About the Role
Own design and delivery of backend services powering a high-impact platform. You’ll build reliable APIs, data models, and event pipelines in TypeScript on AWS, with strong testing and DevOps discipline.
What You'll Do
- Design, implement, and document REST/GraphQL services and internal APIs
- Model data in SQL (Postgres/MySQL); write efficient queries and migrations
- Build cloud-native backends on AWS (ECS/Lambda, API Gateway, SQS/SNS/EventBridge, RDS)
- Set up CI/CD pipelines, IaC (e.g., Terraform/CDK), secrets, and environments
- Add tests (unit/integration) with Jest/supertest; own code reviews and reliability
- Implement observability: logs, metrics, tracing; error budgets and performance guardrails
- Collaborate with Product/Frontend to scope work and ship on a two-week sprint cadence
Must-Have
- 5+ years backend engineering; 3+ years TypeScript in production
- Strong with SQL schema design, transactions, indexing, and query optimization
- Hands-on AWS (serverless or containerized) and CI/CD for multi-env deployments
- Security basics (authN/authZ, OWASP, secrets/KMS), caching, rate-limiting
- Testing mindset (Jest/supertest), clear English, and async collaboration
Nice to Have (Extras)
- NestJS (modules, providers, guards, interceptors)
- Sentry (or similar: Datadog/Honeycomb) for alerts and release health
- Message/event patterns (SQS/SNS/EventBridge, Kafka), idempotency, retries/DLQs
- Performance + cost tuning on AWS; IaC with Terraform or CDK
- Experience integrating with Flutter/React frontends and mobile auth flows
