Job summary

TOPdesk is seeking a Senior Agentic Quality Engineer to drive automated test suites on a platform team, collaborating with Claude Code as the primary testing partner. You will own quality across interfaces, guide test infrastructure, and advance agentic testing maturity while keeping engineers accountable for product quality.

The role focuses on designing robust automated tests, integrating contract testing, data integrity checks, and advanced quality practices.

Qualifications

• 5+ years in test or quality engineering with ownership of automated test suites across a team or service.
• Strong API and integration testing skills — the team's output is almost entirely interfaces.
• Hands-on Claude Code experience — test generation, failure analysis, multi-file editing; not just autocomplete.
• CI/CD fluency — writing and maintaining quality gates, not just running them.
• Writes acceptance criteria that leave no ambiguity for implementation or for Claude to execute against.
• Comfort with data-adjacent testing: databases, data integrity, consistency, and API contracts.
• Fluent English for clear communication with engineers, product stakeholders, and other teams.

Responsibilities

• Design and maintain automated test suites across your team's interfaces and surfaces.
• Write integration and contract tests that validate the interfaces your team provides to others — focused on correctness, schema stability, and clear failure isolation.
• Bring advanced quality practices where they earn their place: property-based testing, fuzzing, mutation testing, contract testing, non-functional testing, and production-quality signals.
• Assess non-functional risks: performance regressions, data consistency, access control, sensitive-data handling, migration safety, backward compatibility.
• Investigate failing builds: triage root cause, distinguish product bugs from test brittleness, clarify ownership across team boundaries.
• Work with Claude, stay accountable — review Claude-generated test suites before merge; verify correctness and coverage.
