Senior Fullstack Engineer (NextJS, NestJS, TypeScript)

The Role
You'll join a small team building a new product component from scratch (greenfield). You'll pair with a senior NestJS engineer, fully own the frontend, and deliver incremental, vertical slices of the product end to end. You'll collaborate closely with the PO, QA, and Scrum Master. What you build will be used by tens of thousands of users daily, so great UX, security, availability, reliability, and cost-efficient operation are crucial. Based full-time in-office at our Koramangala, Bangalore office.

What You'll Do

• Discuss, review, and collaborate on requirements, solution design, and user stories
• Write clean, testable code following best engineering practices (YAGNI, KISS, SOLID, lean)
• Own the frontend: build responsive, accessible, and performant user interfaces in NextJS
• Deliver vertical slices end to end, from the UI via the GraphQL/Apollo BFF down to the NestJS services behind it
• Practise true test-driven (test-first) development; deliver ship-ready work without reliance on manual testing
• Build and run: provide L3 support for your component and help build the L1/L2 knowledge base
• Participate in agile ceremonies and team activities; leverage and improve our AI-assisted coding tools (Claude Code)

What You Bring

• 6+ years as a TypeScript-native fullstack developer
• 3+ years using NextJS as a core, daily technology, with excellent grasp of rendering strategies and GraphQL BFFs
• 2+ years building backend services with NestJS
• A visual eye and strong UX/UI sense; you build responsive, accessible, performant interfaces
• Proven experience in true test-first development; advanced proficiency using Claude Code
• Track record of having built, shipped, and supported NextJS and NestJS applications in production
• Working understanding of microservices and event-driven architectures
• Experience in agile/lean startup environments balancing pragmatism and craft
• Bangalore-based, ready to work from Koramangala, able to start within 30 days

Bonus: Ideally started as a frontend dev and moved toward the backend; experience building/running apps in AWS; design systems and component libraries; IaC with Terraform.

Tech Stack: NestJS, NextJS, AWS (Fargate/ECS/ECR, SNS/SQS, Aurora/Postgres, S3, CloudFront, Service Connect, Kafka), ClickHouse, GraphQL, gRPC, Vitest, Terraform, Docker, CircleCI, Datadog, GitHub, Claude Code.
