Senior Software Engineer in Test

You'll own the quality bar for our innosabi Innovation software platform - designing, building, and running the automated testing and performance validation program that gives all 3 innosabi platform teams confidence to ship fast.

This isn't a "write more tests" role. You'll establish DORA metrics instrumentation from the ground up, architect a Playwright-first automation framework across Angular TypeScript and PHP layers, and enforce quality gates in GitLab CI that the team actually trusts. You'll work closely with the Munich engineering team daily and coordinate cross-platform testing standards with our US-based team.

Quality as velocity. Automation as the default. Metrics that drive decisions.

What You'll Do

• Build DORA metrics from the ground up - Instrument cycle time, deployment frequency, change failure rate, and defect escape rate. Make delivery health visible and actionable across the innosabi Innovation software platform.
• Architect the automation framework - Playwright-first E2E tests covering Angular TypeScript frontend, PHP backend, and API layers. Performance and scale validation for both cloud and on-prem deployments.
• Enforce quality gates in GitLab CI - Integrate automated testing into every MR so quality confidence is built in, not bolted on. Gates that catch real problems without false-positive fatigue.
• Validate across every environment - Cloud deployments, available on-prem test instances, dev, staging, and prod. No release ships without passing the appropriate gate.
• Align standards cross-platform - Establish shared Playwright conventions and compatible quality gates with the US-based product team. Make patterns portable between GitLab and GitHub Actions.
• Lead AI-native testing adoption - Build agentic testing artifacts (prompts, workflows, automation templates) that every engineer on the team can use. Accelerate test authoring and maintenance through AI tooling.
• Document everything that matters - Testing standards, framework architecture, environment setup guides, and regression runbooks that let the team scale without tribal knowledge.
