Full Stack Engineer

📍 Kolkata / Mumbai · Full-time · On-site / Hybrid We're a technology-driven healthcare company building a modern platform used across multiple cities, backed by an established healthcare group with deep infrastructure and relationships already in place. We're looking for a senior engineer to take technical ownership of the platform — architect it, build the critical parts personally, and set the standard for how everything else gets built. This is a hands-on senior role, not a purely managerial one. You'll make the foundational technical decisions, work directly in the codebase, and guide junior engineers and modern AI development tools to build at speed — while you own the parts that matter most.

What you'll own

• The core architecture and data model the entire platform is built on
• Integration with existing production systems and external services
• Data security, access control, and sound handling of sensitive information
• Technical direction, code quality, and review across the stack
• Mentoring junior developers and directing AI-assisted development effectively

What we're looking for

• 5+ years of professional software development, with real ownership of production systems
• Strong data-modeling and system-design ability — you can turn a complex, messy real-world domain into a clean, extensible structure
• Proven experience integrating software with existing, imperfectly-documented systems and third-party APIs
• Full-stack depth: a modern backend language (Python, Node.js, Java, or similar), a modern frontend framework (React, Vue, or similar), and both SQL and NoSQL databases
• Genuine seriousness about security and handling sensitive data
• Fluency with AI-assisted development tools (Claude Code, Cursor, or similar) — you use them to move faster and review their output critically
• The judgment to know when to move fast and when to slow down and be careful

Nice to have

• Experience in healthcare, fintech, or another regulated, data-sensitive domain
• Cloud architecture and deployment experience (AWS, GCP, or Azure)
• Having built a product from zero to one
• Experience leading or mentoring a small team

Why this role matters You won't be a small piece of a large machine. You'll own the technical foundation of a healthcare platform that reaches real patients, with the backing of an established group. If you want architectural ownership, real scope, and a product that genuinely matters, this is it.

• To apply: share examples of systems you've architected and owned end-to-end — that tells us far more than a formal CV.
