Why This Role Matters
Our backend is what keeps checkout, RTO, and payments fast and reliable at ~$2B GMV across 15,000+ merchants. As an SDE 2 you own services end to end, make the architecture calls that keep them performant, and set the technical bar for the engineers around you. The trade-offs you pick show up directly in merchant conversions and platform reliability - this is a builder's seat with real ownership.
What You'll Own
- Design and build backend services primarily in Node.js/NestJS, with Go for select services, backed by Postgres, Mongo, and Redis.
- Own event-driven flows on Kafka - throughput, ordering, and failure handling.
- Make and document the architecture and trade-off decisions for systems you lead.
- Ship features end to end, dropping into the frontend (React/Svelte) when it's the fastest path.
- Strengthen CI/CD, observability, and deployments on AWS.
- Review code, mentor SDE 1s and AEs, and raise the quality bar on the team.
- Take ambiguous problems and drive them to delivery with minimal hand-holding.
Who You Are
- Strong backend engineer in JavaScript/TypeScript on Node.js/NestJS (our primary stack); working knowledge of Go, or ready to pick it up.
- Solid at data modelling across Postgres and Mongo, and knows when Redis earns its place.
- Has built and scaled event-driven systems (Kafka or equivalent).
- At home on the backend but happy to work across the stack in React/Svelte.
- Thinks in systems - scalability, reliability, maintainability - not just features.
- Has mentored engineers and owns code quality and delivery, not just their own tickets.
- Communicates clearly and does well with ambiguity in a fast-moving team.
