$145,600–$156,000 year
On-siteBrea, California, United States
Job Summary
Design, build, and maintain backend services and APIs in Go with supporting infrastructure in TypeScript. Define and operate cloud infrastructure on AWS using CDK, including API Gateway, Lambda, SQS, DynamoDB, S3, RDS, and WAF. Build and scale event-driven pipelines for telemetry ingestion and command delivery while working across the cloud/edge boundary with AWS IoT Greengrass and MQTT. Strengthen multi-tenant isolation through PostgreSQL Row-Level Security, OAuth2, and edge protection. Own reliability by implementing structured logging, retry logic, and latency tracing. Write CI/CD pipelines with Jenkins and Docker, managing security scanning across environments. Collaborate with architecture and product teams to define data contracts and participate in design reviews and on-call rotation.
Required Qualifications
- Strong professional experience building backend services in Go and Node/Typescript (services, middleware, concurrency, testing)
- Hands-on experience with AWS — Lambda, API Gateway, SQS, DynamoDB, S3, IAM, Cognito, RDS/Aurora, CloudWatch — and comfort operating what you build
- Experience writing infrastructure as code, ideally AWS CDK (TypeScript) (Terraform/CloudFormation experience translates)
- Solid understanding of distributed systems — event-driven architecture, message queues, retries/idempotency, dead-letter handling, eventual consistency, and fault tolerance
- Experience designing and securing multi-tenant SaaS backends — tenant isolation, authn/authz (OAuth2, JWT), and API gateway patterns
- Working knowledge of PostgreSQL — schema design, migrations, and query performance (Row-Level Security a strong plus)
- Comfort with CI/CD and containerization — Jenkins (or similar), Docker, and multi-environment promotion
- Strong debugging and observability instincts, and clear technical communication
Desired Qualifications
- Experience with IoT / device-to-cloud systems — AWS IoT Greengrass, MQTT, device provisioning, fleet management, and telemetry pipelines
