MERN Stack Developer

Total Experience: 4+ years

Mode of Hire: Permanent

Required Skills Set (Mandatory): HTML, JavaScript, Node.js, Express.js, MongoDB, React/Next.js, AI Integration (LLMs/APIs - OpenAI, Anthropic, Gemini)

Desired Skills (Good if you have): Cloud Platforms (AWS), System Design, Application Security

What is the role all about?

We're hiring full-stack engineers who build with AI, not the traditional way. You should be fluent in modern web engineering, primarily Node.js, and just as fluent in using LLMs and AI tools (Cursor, Claude Code, and similar) to ship fast. Work that once took a month should take a week; what took a week should take a day.

The role spans a range, from architecting backends for non-trivial products like assistants and agents, to rapidly turning a requirement into a clean, customer-facing app or MVP. Be strong in at least one area, be comfortable across the system as a whole, and tell us where you're strongest so we can place you accordingly.

What will you do?

• Plan, build, and ship product features end-to-end, with AI embedded where it has the most impact.
• Integrate LLMs and AI APIs into production-grade applications.
• Use AI tools to prototype, build, and deliver at high speed without sacrificing quality.
• Design scalable APIs and data models with Node.js, Express.js, and MongoDB.
• Build responsive, performant, customer-facing interfaces with React/Next.js.
• Contribute to design discussions, code reviews, and architectural decisions.

What are we looking for?

AI leverage: 

• You've shipped real things using LLMs or AI APIs and instinctively reach for AI to move faster. 
• Comfortable with prompt engineering and judging AI output for production-readiness.

Engineering depth and delivery:

• Solid fundamentals: problem-solving, data structures, and how systems fit together. 
• At least 2+ years across frontend (React/Next.js), APIs (Node.js/Express.js), and databases (MongoDB). 
• You write clean, production-grade code and you ship.
• Knowledge of application security or ethical hacking is an advantage.

Culture

• Work with performance-oriented teams driven by ownership and passion.
• Learn to design systems for high accuracy, efficiency, and scalability.
• No strict deadlines, focus on delivering quality work.
• Meritocracy-driven, candid culture. No politics.
• Very high visibility regarding which startups and markets are exciting globally.

You will directly lead, mentor, and scale a high-performing 8-person software team team consisting of 7 software developers (in-house and full-time contractors), 6 AI/data scientists, 1 product designer, and 5 QA specialists.

This is a hands-on architecture and leadership role. You will own the system design, enforce engineering excellence, and build low-latency, highly available pipelines that handle real-time clinical workflows.

Core Responsibilities

• System Architecture & Scaling: Design and scale robust, event-driven microservices using Node.js and high-performance user interfaces using React.js to support multi-modal AI clinical tools.
• AI & Software Integration: Architect the data pipelines and APIs that wrap, serve, and orchestrate heavy AI models (voice-to-text transcription, NLP, and radiology reporting tools).
• Real-Time Data Streaming: Implement secure, low-latency, full-duplex communication protocols (WebSockets, WebRTC) to stream live audio and heavy medical data feeds seamlessly between the client and backend.
• Engineering Leadership: Manage, mentor, and inspire a hybrid team of 7 software developers and 5 QA engineers. Drive agile sprint planning, set high standards for clean code, and establish robust CI/CD pipelines.
• Production Stability: Ensure high availability, data security (HIPAA/healthcare compliance standards), and performance monitoring for a product already live and actively used in market.
• Cross-Functional Collaboration: Partner closely with the 6-member AI research team, design resources, and business stakeholders to translate complex clinical product requirements into technical roadmaps.

Required Technical Skills & Experience

• 10+ years of professional software engineering experience, with at least 3+ years in a Tech Lead or Engineering Manager capacity within a fast-paced startup or high-growth tech environment.
• Deep production-level mastery of Node.js (Express, NestJS, or similar) and React.js (including advanced state management like Redux, Context API, or Zustand).
• Proven experience building event-driven architectures and handling asynchronous workloads using message brokers like RabbitMQ, Kafka, or AWS SQS/SNS.
• Strong proficiency with real-time streaming tools, data processing, and protocol management (WebSockets, Socket.io).

• Solid understanding of database design, optimization, and scaling (SQL and NoSQL).

General Attributes

• Exceptional communication and decision making skills.
• Demonstrated ability to mentor teams and influence architecture direction.
• High ownership mindset and ability to deliver against clear plans.
• Strong adaptability and comfort operating in fast moving environments.

Preferred (Bonus) Qualifications

• Prior experience in the Health-Tech / Med-Tech domain, specifically dealing with medical imaging systems, electronic health records (EHR), or healthcare compliance.
• Familiarity with medical imaging/data standards or frontend medical web viewers (e.g., Cornerstone.js, OHIF Viewer, DICOM web protocols) is a massive plus.

What We Offer

• Competitive Compensation: Highly attractive base salary aligned with top-tier Bengaluru tech standards.
• High Autonomy: Direct influence over technical stack decisions, product architecture, and engineering culture.
• Mission-Driven Work: The opportunity to build software that directly saves lives and transforms global healthcare via artificial intelligence.

Founding Full-Stack Engineer

Consumer AI | Delhi (Hybrid) | Building for the US Market

The Opportunity

We are a pre-seed startup redefining fashion discovery. We believe the future of e-commerce isn't about search bars and endless scrolling; it’s about context-aware curation.

We are looking for a Founding Full-Stack Engineer who sits at the intersection of Systems and Design. You will be the technical anchor of the team, turning chaotic web data into a fluid, consumer-grade experience.

The Role

You won't just be writing code; you will define the product's architecture. We need Vertical Ownership—the ability to take a feature from a raw database row all the way to a pixel-perfect interaction on the screen.

• The Data Engine (Backend & Scraping): You will build robust data pipelines that scrape and frequently refresh data from top fashion retailers. You will further structure and enrich this data, add additional attributes and prepare it for downstream consumption. Added bonus: prior experience with feature engineering
• The Experience (Frontend): You will craft the user interface. We are building a consumer brand, so "functional" isn't enough—it needs to feel "alive.”. If you have a refined design sense, and prior exposure to building eComm websites with complex landing and category pages, then you are the right fit for this role. 
• The Intelligence (AI Integration): You should be able to understand and re-run existing research algorithms on Fill-In-The-Blank (FITB) tasks.

The Toolkit

• Core Stack: Python for the heavy lifting; JavaScript/TypeScript (React) for the web interface.
• Data Ops: Experience building complex scrapers, handling proxies, and managing data pipelines is non-negotiable.
• Design Engineering: A strong grasp of building advanced eCommerce components (multi-tile grid layouts, drag-and-drop elements, etc.)
• Low-code tools: Adept at rapidly prototyping with Replit, Lovable, etc.

The DNA We Are Looking For

• You are a Builder, not just a Coder. You prefer shipping a live prototype over debating a PR for three days.
• You have Taste. You understand that building for the US consumer market requires a level of polish and minimalism that standard B2B SaaS ignores.
• You are "T-Shaped." You have deep expertise in one area (either scraping or frontend), but you are dangerous enough across the entire stack to build solo.
• You embrace the Chaos. You know how to build structure out of messy unstructured data.

Why Join Now?

• 0 to 1 Ownership: No legacy code, no technical debt. Just you, the founders, and a blank editor.
• Global Impact: You are building from India, but for the most competitive consumer market in the world (USA). The standards are higher, and so is the reward.
• Founding Team Status: Competitive pay with a future path to equity
