Staff Backend Engineer

Job summary

Carter Systems is hiring a Staff Backend Engineer to work remotely from Japan. Backend role focused on API design, data modelling and making slow things fast. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. Employment is through our payroll partner in Japan. Salary is paid monthly in local currency. Core hours are 10:00 AM to 4:00 PM UK time. Good written English matters here, since most updates are written.

Responsibilities

• Instrument services with metrics, structured logs and OpenTelemetry traces
• Containerize services with Docker and deploy them to Kubernetes or ECS
• Handle on-call for services the team owns and lead incident follow-ups
• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ
• Tune slow queries, add indexes and read query plans
• Write integration and contract tests so API changes don't break consumers
• Document APIs in OpenAPI and keep the docs current
• Add caching with Redis where it actually helps, and remove it where it doesn't

Qualifications

• 7+ years of backend development experience in a production environment
• Understanding of concurrency, transactions, idempotency and retries
• Hands-on experience with AWS, GCP or Azure services
