- Lead the end-to-end design, development and delivery of scalable, secure web applications using NextJS, ReactJS and FastAPI.
- Partner with the Solution Architect to shape system design, technology choices and engineering standards for the platform.
- Drive code quality, performance and reliability through reviews, refactoring, observability and continuous improvement.
- Mentor full-stack and front-end engineers; raise the engineering bar through coaching, pairing and tech talks.
- Champion compliance-by-design and secure coding practices appropriate to a regulated NBFC environment.
- End-to-end delivery of complex, cross-cutting features (NextJS + FastAPI) aligned to the architecture roadmap.
- Performance & reliability of owned services p95 latency, error budgets and uptime SLOs met every quarter.
- Mentor and grow a pod of 25 engineers; demonstrable improvement in their delivery velocity and quality.
- Reduce technical debt through refactoring, library upgrades and removal of dead code.
- Proven track record of designing and shipping high-availability, fault-tolerant systems serving real production traffic.
