About Venxr
VenXR is an AI-driven AdTech startup building AdsGPT, redefining how brands plan, execute, and optimize ad campaigns through AI. We're a fast-growing, lean team looking for a Product Engineer who can own features end-to-end, from idea to shipped product.
About the Role
We're looking for a Product Engineer who thinks like a builder, not just a coder. Someone who cares as much about why we're building something as how it's built, and takes real ownership of the product outcomes, not just the code they ship.
Tech Stack
Frontend: React.js | Backend: Python (Django) | AI: Claude / LLM-driven development
Roles & Responsibilities
- End-to-End Feature Ownership
- Own features from concept to deployment — writing clean, scalable code while staying closely tied to the product goal and user impact behind it.
- Full-Stack Development
- Build and maintain front-end interfaces in React.js and back-end systems in Python/Django, ensuring performance, reliability, and scalability across the product.
- Product Thinking
- Work closely with Product, Design, and Founders to shape specs, question assumptions, and suggest simpler or smarter ways to solve user problems.
- Rapid Iteration
- Ship fast, test in production, gather feedback, and iterate, balancing speed with code quality.
- Cross-Functional Collaboration
- Partner with Design and Data teams to bring dashboards, AI-driven features, and data visualizations to life.
- System Design & Architecture
- Contribute to technical architecture decisions, ensuring the codebase stays scalable as the product and team grow.
- Debugging & Problem Solving
- Diagnose and resolve complex technical issues quickly, treating downtime or bugs as urgent, customer-impacting problems.
- AI-Native Development
- Actively build with AI — using Claude and other LLM tools not just to assist coding, but to develop AI-powered features, prompt workflows, and intelligent product capabilities within AdsGPT itself.
Requirements
- 1-2 years of experience as a Product Engineer, ideally in a startup or B2B SaaS environment
- Candidates with B.Tech in CSE, AI/ML or any other equivalent educational background from Tier-1 and Tier-2 colleges will be preferred
- Strong proficiency in React.js for front-end development
- Strong proficiency in Python, with hands-on experience in Django for back-end development
- Solid understanding of REST APIs, databases (SQL/NoSQL), and system design fundamentals
- Hands-on experience building with AI tools (like Claude), not just using them for coding assistance, but developing core AI products.
- Experience working directly with Product/Design teams, not just executing tickets
- Comfortable working in ambiguous, fast-changing environments with minimal hand-holding
- Strong debugging and problem-solving skills
Good to Have
- Familiarity with the Model Context Protocol (MCP) for securely connecting LLMs to external tools and APIs.
- Experience building conversational AI interfaces or managing complex multi-turn chatbot state across various platforms and channels.
- Experience in AdTech, MarTech, or data-heavy SaaS platforms.
- Exposure to cloud infra (AWS/GCP/Azure), Docker, and CI/CD pipelines.
- Experience with LLM evaluation/monitoring tools (Ragas, LangSmith, Langfuse, or similar).
- Experience with data visualization libraries (Recharts, D3.js, Chart.js).
- Familiarity with compliance-aware or explainable AI design in regulated domains.
What We Look For In Candidates
- Customer Obsession – A genuine curiosity about how your code impacts the customer's experience, not just whether it compiles.
- Ownership – You drive features to completion, chasing down blockers instead of waiting on them.
- Stakeholder Understanding & Management – You know when to loop in Product, Design, or Business to unblock yourself fast.
- High Standards – You hold your own code to a higher bar, even when no one's checking.
- Disagree and Commit – You debate technical decisions hard, then commit fully once the call is made.
- Simplify Relentlessly – You reach for the simplest working solution, not the most "clever" one.
- Solidarity with the Team – You show up for your teammates, no invitation needed.
- Vitality – You bring real energy and resilience that keeps you (and others) going.
- Why Join Venxr?
- Be part of a fast-growing startup that puts data at the heart of every decision.
- Opportunity to work on high-impact, real-world business challenges.
- Collaborative, transparent, and learning-oriented work environment.
- Flexible work culture with a strong focus on career development.

We are looking for a Founding Product Engineer to help build the platform from the ground up. This is a 0→1 product engineering role where you work directly with the founder and engineering team to turn ambiguous product problems into working software.
You will be expected to:
Understand the problem → explore solutions → make trade-offs → design → build → ship → measure → improve.
WHAT YOU WILL BUILD & OWN
MOBILE
Onboarding, profiles, discovery, interactions, messaging, activities, and companion experiences.
SOCIAL SYSTEMS
Relationships, social graph, compatibility, and interaction flows.
BACKEND
APIs, services, authentication, notifications, and background processes.

• Mindset: High ownership, curiosity, strong fundamentals, clear communication, learning velocity, and the ability to work through ambiguity.
WHAT WE LOOK FOR
MOBILE CAPABILITY
Can you build and ship a polished mobile experience?
ENGINEERING DEPTH
Do you understand why a system works, not just how to make it run?
PRODUCT JUDGMENT
Can you determine what should be built when the problem is ambiguous?
ARCHITECTURE / SYSTEMS
Can you reason across APIs, databases, services, real-time systems, scale, and cost?
SPEED OF EXECUTION
Can you move from idea → prototype → production quickly without compromising fundamentals?
AI FAMILIARITY
Do you understand how modern AI can become a useful, reliable product capability?

Through the platform we believe that these professionals can be empowered to deliver better care to patients (like our families) throughout the globe.
In its current (and evolving) form, it is a live learning and engagement platform seeing tremendous week-on-week growth through stellar speakers and a very active early community. The product is in the growth stages and you will be playing a key role in steering the tech to create a scalable and lovable product experience.
We are backed by startup, VC and PE veterans including Kunal Shah (CEO, Cred), Raghunandan G (Zolve, ex-TFS), Avnish Mehra (Everstone) and more.
Medflix is a platform by PlexusMD (www.plexusmd.com/app), a network trusted and loved (4.4 stars on Playstore and 4.4 on Appstore) by more than 3 lakh doctors in India and working closely with leading healthcare providers and companies like AIIMS, Jaslok, Hinduja, Apollo, HCG, Elsevier, Association of Physicians of India, Indian Association of Cardio-thoracic surgeons, Society of Nuclear Medicine, Govt of Gujarat (HFW Dept), Govt of Haryana (SIFHW), McKinsey and company, Takeda, Mankind and others.
About the Role
Tech stack (expertise in all is not required, experience in some will be sufficient):

Benefits and growth
While we ensure competitive compensation (plus ESOP options for deserving candidates), at Medflix, you will also have a strong say in how final solutions look. You will get the opportunity to learn to steer an accelerating rocket ship.
College credentials, background or years of experience are no bar for growth inside the company for enthusiasts who believe in our mission and demonstrate that passion to create a product that healthcare workers love.

We're hiring an SDE-2 Full Stack Engineer to build the web experiences adjusters and policyholders use to report, track, and settle insurance claims. You'll spend most of your time on the frontend in React and TypeScript — owning features end to end from design handoff to production — while understanding and contributing to the backend services that power them.
Our claims services are written largely in Go, so Go experience is a strong plus, though solid backend fundamentals in any language are what matter most. We're also building a desktop application in Electron, so Electron experience is a real plus. You'll design APIs alongside backend engineers, reason about data models, and understand how your UI behaves under real production load.
This is a mid-level role for someone who ships independently, raises the bar on frontend quality, and wants to learn the claims domain deeply. The people using what you build are often filing a claim on a bad day or working through a high-volume queue — thoughtful, reliable UX matters here.
What You'll Own
- Frontend features across the claims lifecycle: claim intimation, claim status tracking, document and photo upload, adjuster workbench tools, and settlement flows
- Translating designs into accessible, responsive, performant UI, and partnering with design and product on usability
- API design with backend engineers, and contributions to Go services when a feature needs an endpoint, a data model change, or a fix
- Integrations with third-party vendor APIs — surveyors, garages/repairers, hospitals or TPAs, payment gateways, document verification — including error handling, retries, and graceful degradation when a vendor is slow or down
- Frontend observability: error tracking, performance monitoring, user-journey analytics, and alerting so we know when a claims flow breaks before customers tell us
- Test coverage and observability for everything you ship — unit, integration, and end-to-end
Who You Are
- You take a feature from ambiguous requirement to production without waiting to be told each step
- You explain technical tradeoffs clearly to engineers, product, and design, in writing and in conversation
- You debug across the stack — browser, API, database — and fix root causes, not symptoms
- You review others' code generously, ask for review on your own, and help junior engineers level up
Required Qualifications
- 3+ years of professional software engineering experience, with at least 2 years focused on frontend development
- Strong command of React, TypeScript, and Tailwind CSS, including state management, component architecture, and performance tuning
- Solid HTML/CSS fundamentals, hands-on Tailwind CSS experience, accessibility (WCAG) awareness, and experience building responsive, cross-browser UI
- Working knowledge of backend systems: REST or gRPC API design, relational databases and SQL, authentication/authorization, and how services are deployed and monitored
- Hands-on backend experience in at least one server-side language (Go preferred; Java, C#, Python, Node.js, or similar also fine)
- Experience writing automated tests at multiple levels
- Experience integrating third-party APIs into a product, and instrumenting frontend code with error tracking and performance monitoring
Nice to Have
- Experience building or shipping Electron desktop applications: packaging, auto-updates, main/renderer process communication, and native OS integration
- Production experience with Go: writing services, concurrency patterns, testing, and the standard toolchain
- Experience in another regulated domain (fintech, healthcare, banking) where auditability, data privacy, and compliance shape product decisions
- Familiarity with event-driven architectures, message queues, or workflow engines
- Cloud platform experience (AWS, GCP, or Azure), containers, and CI/CD
- Exposure to applied AI/ML features in product — document classification, intake triage, or LLM-backed assistants
About Vijay Sales
Vijay Sales is a consumer electronics and appliances retailer, selling through its stores across India, its website and its app.
Our technology team builds the software the business runs on: order management, customer support automation over WhatsApp, reviews and ratings, and the dashboards our operations teams use every day.
The role
We are hiring full stack engineers who can take a feature from spec to production across React, Node.js and MongoDB.
You will work on customer-facing and internal products, often both in the same week. One sprint may be a review submission page used by customers on their phones. The next may be an API that pulls order status from our order management system for the support bot.
We are looking for engineers with 3 to 6 years of experience who are comfortable owning both the front end and the back end of what they ship.
What you'll do
- Build responsive, mobile-first interfaces in React using our in-house UI component libraries.
- Design and build REST APIs and background services in Node.js.
- Model data in MongoDB and keep queries fast as collections grow.
- Integrate with the systems the business runs on: order management, ERP, point of sale and ticketing.
- Build messaging flows over WhatsApp, email and SMS, including delivery tracking, retries and fallbacks.
- Work with the conversational AI team to expose order, invoice and support actions to the customer support bot.
- Write tests, review code and own your features in production, including monitoring and fixing what breaks.
- Work directly with product and operations teams to turn a business problem into a working release.
Our stack
React, Node.js and MongoDB are the core. Everything else in the table is what you will connect to or build alongside.
- Front end: React, with Vijay Sales' in-house UI component libraries
- Back end: Node.js services and REST APIs
- Database: MongoDB
- Messaging: WhatsApp Business, Amazon SES for email, RCS and SMS as fallback
- Conversational AI: LangChain and Rasa, behind the customer support bot
- Business systems: Order management (OMS), ERP, POS, Ticketing Systems
What we're looking for
- 3 to 6 years of professional experience building and shipping web applications.
- Strong JavaScript and TypeScript fundamentals: async patterns, the event loop, modules, error handling.
- Solid React skills: hooks, state management, component design, performance on low-end mobile devices.
- Hands-on Node.js experience: building REST APIs, authentication with JWT, role-based access, input validation.
- Working knowledge of MongoDB: schema design, indexing, aggregation pipelines.
- Experience integrating third-party APIs and webhooks, and handling their failures gracefully.
- Comfort with Git, code review, automated tests and CI/CD.
- Clear written and spoken communication. You will talk to operations and business teams, not only engineers.
Nice to have
- Experience with the WhatsApp Business API, Gupshup or similar messaging platforms.
- Exposure to LLM application development: LangChain, retrieval, tool calling, or bot frameworks such as Rasa.
- Background in retail, e-commerce or order management systems.
- Experience integrating with ERP or POS systems.
- Familiarity with AWS, Redis and message queues.
- React Native or other mobile app experience.
Why join and how to apply
- Your work reaches real customers and store teams quickly. There is very little distance between a release and the people who use it.
- You own features end to end, from the first conversation with the business team to production.
- You get hands-on exposure to conversational AI and LLM-based products alongside core full stack work.

What Success Looks Like
In the first 30 days, you will:
- Understand our thesis, target customer, and product direction
- Help refine the first product wedge
- Build and iterate on early prototypes
- Set up core frontend and backend foundations
- Move quickly across product, design, and engineering decisions
In the first 60–90 days, you will:
- Ship the first usable product prototype
- Help build demo experiences that clearly communicate the product vision
- Create the first version of the adaptive frontend architecture
- Help test the product with early users, customers, or design partners
- Identify what should become production-grade versus what should remain experimental
Leadership Opportunity
This is a founding role with significant upside.
For the right person, strong performance can lead to a leadership position as the company grows. We are looking for someone who can become a long-term technical and product partner — someone who can help build the first version, shape the architecture, hire future engineers, and potentially lead major parts of the engineering organization.
This is an opportunity to join at the earliest stage and help define both the product and the company.
Why Join
- Build from zero with high ownership
- Work directly with the founder
- Help create a new category of software
- Own meaningful technical decisions from day one
- Opportunity to join the leadership team as the company scales
