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.
About the role
We are hiring a Principal Engineer to own the hardest technical problems in our product and see them through from first sketch to stable production. You will set technical direction, design systems that scale, and raise the engineering bar through your own work and the people around you. This is a hands-on leadership role: you write code, review designs, and ship.
What will you do?
You will own outcomes, not just tasks. Expect to spend your time on the following.
• Own projects end to end. Take an ambiguous problem, shape the requirements, design the solution, break down the work, deliver it to production, and stay accountable for how it runs afterwards.
• Lead system design. Author and review architecture for services, data pipelines and integrations, with clear trade-offs on scale, latency, cost, consistency and reliability.
• Write and review critical code. Build the hardest components yourself, and set standards for code quality, testing and maintainability through code and design reviews.
• Own deployment and operations. Design CI/CD, infrastructure and release strategies. Drive observability, on-call readiness, incident response and post-incident learning.
• Solve hard problems. Debug production issues across the stack, and find root causes in performance, concurrency, data and scaling problems.
• Mentor and multiply. Coach senior and junior engineers, grow future tech leads, and make the whole team faster and more confident.
• Partner across functions. Work with product, design, data and business teams to turn goals into technical plans, and to say no or reshape scope when needed.
• Shape technical strategy. Guide build-versus-buy decisions, manage tech debt, evaluate new technologies, and contribute to the engineering roadmap.
• Raise the bar. Help define engineering practices, hiring standards and culture, and take part in interviewing.
What are we looking for?
• Bachelor's degree in Computer Science or a related field, or equivalent practical experience.
Core engineering
• 10+ years of professional software engineering, with a track record of shipping and running production systems.
• Strong computer science fundamentals: data structures, algorithms and complexity, operating systems, networking, databases and concurrency.
• Fluency in at least one major backend language (for example Python, Go, Java, or Node.js/ TypeScript) and the ability to pick up others quickly.
• Deep knowledge of relational and NoSQL data stores: schema design, indexing, transactions, query tuning and replication.
System design and problem solving
• Proven ability to design distributed systems that are scalable, fault tolerant and cost aware, and to explain the trade-offs clearly.
• Experience with APIs, event-driven and asynchronous architectures, queues, caching and service-to-service communication.
• A structured approach to ambiguous problems: break them down, test assumptions, decide with incomplete data, and measure results.
• Strong debugging instincts, including performance profiling and production troubleshooting.
Delivery and operations
• Have led at least two significant projects from inception to production, including planning, milestones, risk management and launch.
• Hands-on experience with deployment: CI/CD pipelines, containers (Docker, Kubernetes), a major cloud (AWS, GCP or Azure), and infrastructure as code.
• Practical experience with monitoring, logging, alerting, SLOs and incident management.
• Habit of writing tests and automation, and of leaving systems more reliable than you found them.
Leadership and communication
• Experience leading engineers without formal authority, through influence, mentoring and clear technical writing.
• Excellent written and verbal communication: design docs, RFCs and concise updates to non-technical stakeholders.
• Ownership mindset, sound judgment on priorities, and comfort working in a fast-moving environment.
Nice to have
• Experience in fintech, lending or another regulated, data-heavy domain.
• Exposure to AI/ML or LLM-based systems in production: model serving, evaluation, retrieval, and cost and latency management.
• Deep experience with data engineering: streaming, batch pipelines, warehouses or search systems.
• Security and compliance awareness: authentication, encryption, audit trails, secure SDLC.
• Experience with multi-tenant SaaS, high-throughput systems or zero downtime migrations.
• Open-source contributions, conference talks, or technical writing.
• Experience scaling an engineering team or helping set up hiring and onboarding practices.
