About Medflix - empowering healthcare professionals for better care
Medflix (www.medflix.app/app) is a platform where healthcare professionals (doctors, medical students and more) stay updated through live talks, Q&As, support material and more. 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):
- React / Next.js (required, at least 1 year of experience)
- Express.js (required, at least 1 year of experience)
- Familiarity with cloud services (gcp / azure / aws)
- PostgreSQL (or expertise in any relational database)
- Redis
- Docker/Kubernetes deployment (good to have)
For this role we are looking for engineers with an entrepreneurial mindset, an understanding of how startups operate and who like to get their hands dirty when unknown things come their way. You will work closely with the product team to prioritise and ship features with a predictable cadence.
As this role is full-stack, you need to have a good understanding of frontend design and be obsessed with responsiveness and pixel-perfect behaviour. On the backend side, an OCD for efficiency and optimisation is a required personality trait.
Demonstrated history of solving hard problems (frontend/backend or both) is a great-to- have.
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.
The recruiter has not been active on this job recently. You may apply but please expect a delayed response.
About Byldd:
Byldd is a Startup Studio that helps founders launch and scale software companies. We work closely with founders to refine ideas, identify core pain points, build scalable software products, acquire initial customers, and support growth.
At Byldd, engineers get the opportunity to work on diverse and challenging projects across industries like fintech, healthcare, AI, operations, and enterprise software. Since we work with multiple startups at different stages, the problems are rarely repetitive — one week you may be building an AI-assisted workflow tool, and the next you may be architecting a scalable SaaS platform.
Our engineering culture is strongly focused on ownership, fast execution, and leveraging modern development workflows — including AI-assisted development using tools like Claude Code, Cursor, ChatGPT, GitHub Copilot, and other AI tooling to improve speed, quality, and problem-solving.
We primarily work with technologies such as React/Next.js, Node.js, TypeScript, MongoDB, and modern cloud infrastructure.
About the role:
We’re looking for experienced Full-Stack Engineers with a strong backend inclination to join us on core business projects.
Your role will involve understanding business requirements, product flows, and mockups. We’ll provide the “what” and the “why” behind the product decisions, and you’ll take ownership of translating them into scalable technical solutions.
While this is a full-stack role, the expectation is backend-heavy ownership — including system design, APIs, database architecture, integrations, scalability, and performance optimization. You’ll collaborate with founders and senior engineers to architect and build products end-to-end.
Since we move fast, we highly value engineers who can independently figure things out, use AI effectively in their workflows, and ship high-quality products with speed.
This role is ideal for someone who enjoys combining strong backend engineering fundamentals with modern AI-assisted development practices.
What You’ll Do
- Build and ship scalable full-stack applications from scratch
- Design and develop robust backend systems, APIs, and database architectures
- Work closely with founders, designers, and product teams
- Architect systems with scalability, maintainability, and performance in mind
- Use AI-assisted development tools (Claude Code, Cursor, ChatGPT, Copilot, etc.) to improve development speed and productivity
- Review, debug, and optimize production systems
- Think through edge cases, reliability, and long-term scalability
Who you are:
- You have 2+ years of non-internship experience as a full-stack developer with strong backend expertise
- You enjoy building products from 0 → 1
- You think beyond tasks and understand business objectives
- You are comfortable taking ownership and contribute towards making technical decisions
- You actively use or are excited to use AI tools in your engineering workflow
- You are strong in problem-solving and figuring things out independently
- You care deeply about writing clean, maintainable, scalable code
- You enjoy working in fast-paced startup environments
- You’re comfortable contributing across the stack while being particularly strong on the backend side
Preferred Tech Stack
(Experience in some or most of the following is preferred)
- Node.js
- TypeScript
- MongoDB
- Express.js
- React / Next.js
- REST APIs
- Cloud deployment & modern dev tooling
Experience with AI-assisted coding tools and workflows is a strong plus.

Job description
Join a small engineering team improving existing software and building new capabilities. You will own backend reliability, data correctness and asynchronous processing, and guide technical decisions across application and automation engineers.
This is a hands-on position involving production debugging, measured performance improvements, safe changes to existing code and release ownership. Company-provided AI coding tools support the work; you remain responsible for understanding and verifying what ships.
Responsibilities
- Develop and improve TypeScript/Node.js APIs and Rust services, including concurrency, failure handling and durable processing.
- Diagnose slow queries and API paths; improve schemas, indexes, caching and background jobs based on evidence.
- Define reliable service contracts, event identities, retries and reconciliation across connected components.

- Strong database fundamentals, including query analysis, transactions or consistency trade-offs, and safe migration practices.
- Experience with API authentication, automated tests, Git review, logging and controlled deployment.
- Clear written English for task plans, technical decisions, incident notes and constructive review discussions.
- Evidence of taking responsibility for a problem, responding to feedback and verifying the corrected result.
Experience with MCP/tool integrations, containerised services or performance profiling is useful. Depth in the core responsibilities matters more than a long list of frameworks.
How we work and hire
Work follows documented tasks, approval, implementation, review and verification. We value early escalation of blockers and honest reporting of results.
Selection includes a short AI-assisted initial interview, an approximately 60–90-minute practical using synthetic material, and an on-site technical discussion. Final hiring decisions include human review.
