Contract: 1 year
The Role
As the Lead Node.js developer, you’ll own the design, implementation, and operation of backend services on AWS. You’ll architect secure, scalable APIs and event-driven workloads (Lambda, API Gateway, SQS/SNS/EventBridge, Secrets Manager), set engineering standards, and lead a small team through design reviews, code reviews, and incident response. This role sits in a regulated environment, so reliability, observability, and compliance are central to how you build.
What You’ll Do
- Deliver features end-to-end: design and build Node.js/TypeScript APIs, AWS Lambda functions, and backend services from user stories and technical designs.
- Review requirements for feasibility, scope, and risk; propose pragmatic alternatives where needed.
- Investigate production issues, perform root-cause analysis, and implement resilient fixes with tests.
- Champion quality: write clean, testable code; add unit/integration tests; uphold performance, security, and WCAG accessibility best practices.
- Lead code reviews, maintain coding standards, and improve shared components/libraries.
- Partner with BAs to refine acceptance criteria and clarify edge cases to ensure business value.
- Work in Agile ceremonies (grooming, stand-ups, retros); provide accurate estimates.
- Collaborate on CI/CD, feature flags, and observability(logs/metrics/traces) for safe, frequent releases.
- 6+ years relevant backend experience, including 2+ years hands-on with Node.js on AWS Lambda.
- Strong AWS background: Lambda, API Gateway, S3, DynamoDB/RDS, CloudWatch; experience with handlers, layers, and cold-start awareness.
- Event-driven design: idempotency, DLQs, retries with backoff.
- Proficiency in TypeScript/JavaScript, async patterns, structured error handling.
- Caching expertise (e.g., Redis).
- Authentication/authorization: OAuth2/OIDC, JWT; bonus for Amazon Cognito.
- Testing with Jest/Mocha(including API/integration tests).
- Practical Git workflows (branching strategies, pull-request reviews).
- Security & compliance in regulated contexts: audit trails, data retention, PII handling, OWASP awareness.
- Excellent system design fundamentals (latency, throughput, cost).
- Bachelor’s degree
in a relevant field.
- Infrastructure as Code (e.g., AWS CDK, Terraform) and packaging/deploy pipelines.
- Feature-flag platforms and progressive delivery.
- Experience leading on-call/incident response and post-incident reviews.
- Performance tuning and cost-optimization on serverless workloads.
