• Document APIs in OpenAPI and keep the docs current
• Coordinate with frontend and mobile engineers on API contracts and versioning
• Reduce cloud costs by right-sizing services and cleaning up unused resources
• Model data and write migrations for PostgreSQL, MySQL or DynamoDB
• Secure endpoints with OAuth 2.0, JWT validation and proper input checks

About you

• 3+ years of backend development experience in a production environment
• Hands-on experience with AWS, GCP or Azure services
• Experience designing and versioning HTTP APIs
• Understanding of concurrency, transactions, idempotency and retries
• Comfort reading logs, metrics and traces to debug problems in production
