Run and maintain services in production, including:

Manage vendor-specific software services running in AWS
Write automated tests and contribute to improving test coverage and quality
Participate in CI/CD pipelines, deployments, and operational procedures
Work closely with product and security stakeholders to translate requirements into technical solutions
Continuously improve engineering standards, tooling, and reliability
What it takes
Expertise in TypeScript
Strong backend engineering fundamentals with Node.js and NestJS or Express
Experience designing and building REST APIs
Understanding of authentication protocols: OAuth 2.0, JWT
Hands-on experience with AWS (ECS, Lambda, CloudFront, S3, Secrets Manager)
Familiarity with Infrastructure as Code (CloudFormation or CDK/Terraform)
Strong Git practices and CI/CD experience (GitHub Actions or similar)
Experience writing unit and integration tests (Jest)
Nice to Have
Experience with identity, authentication, or MFA systems
Familiarity with Kong API Gateway or similar
Exposure to Aurora PostgreSQL or DynamoDB
