## About the Role

We want an engineer who thinks in systems, and who is motivated to define how software gets built rather than just execute tickets.

 * Real enthusiasm for agentic coding, and hands-on experience directing coding agents (Claude Code or similar) on non-trivial work.
 * 4+ years of backend software engineering, specifically with TypeScript and Node.js. Strong enough in the fundamentals to judge agent output, not just accept it.
 * Solid grounding in backend architecture and system design.
 * Experience building scalable, distributed systems.
 * Experience with GitLab, Jira, and CI/CD pipelines.
 * Knowledge of Redis, MySQL, MongoDB.

Bonus points:

 * Experience influencing technical direction within a team.
 * Ideas about agentic testing, verification, or developer tooling, and a track record of building or improving it.
 * Experience with event-driven or message-based architectures.
 * Hands-on experience with Google Cloud, including Pub/Sub, Cloud Tasks, Cloud Run, and Kubernetes.

## Description

You will join a young, fast-moving team in Tilburg, building backend systems for a high-scale SaaS platform in an agentic-first way. We operate like a high-growth startup with the backing of a global powerhouse - a small team moving fast, with real impact you can see daily. Concretely:

 * Build and scale backend systems, with coding agents as part of how you work: decompose problems, write clear specs, and steer the work to a correct result.
 * Own the quality bar. Review and validate agent-generated code with the depth to catch what an agent gets subtly wrong, and take end-to-end ownership of the components you ship.
 * Push agentic testing forward. Help move us from automated coding into agent-driven testing, so correctness scales with speed instead of lagging behind it.
 * Help build the harness. With frontier models converged, the tooling around the agent is where most of the leverage now lives, and our team is building that layer at Cape.io: shared skills, codebase context served over MCP, agentic testing that blocks bad code from merging, and tight tool curation. You will help shape and extend it.
 * Make architecture decisions for performance, reliability, and long-term maintainability on our Node.js and TypeScript services.
