Senior Backend Engineer, Go

A bit about us

Our engineering, trust and safety, and customer support teams work across offices in Rotterdam and several other countries. Traffic during holiday peaks can reach ten times normal levels, and the platform is built for it. Product reviews happen on Thursdays, with demos of whatever shipped that week.

Waal Online has an opening for a Senior Backend Engineer, Go. This hire will help us split a large monolith into a handful of well-defined services without breaking anything customers rely on. Remote within the Netherlands. The team meets in Rotterdam once a quarter, travel covered. We do not have many meetings. Most updates happen in writing. Most communication happens in Slack, with short video calls when needed.

Main duties

Coordinate with frontend and mobile engineers on API contracts and versioning. Design and build REST and gRPC APIs in Go, Java or Python. Secure endpoints with OAuth 2.0, JWT validation and proper input checks. Handle on-call for services the team owns and lead incident follow-ups. Document APIs in OpenAPI and keep the docs current. Model data and write migrations for PostgreSQL, MySQL or DynamoDB.

Qualifications

7+ years of backend development experience in a production environment. Familiarity with Docker and CI/CD pipelines. Hands-on experience with AWS, GCP or Azure services. Understanding of concurrency, transactions, idempotency and retries. Comfort reading logs, metrics and traces to debug problems in production.
