Software Development Engineer in Test II, NavNative

What You'll Do

We are looking for smart, fast-learning engineers who care as much about proving that navigation works as about making it work. As an SDE(T), you will:

• Build and maintain the unit, integration, and functional test architecture for a C++17 library, and the CMake and CI pipelines that run it.
• Turn real-world location recordings into regression tests, and define the quality metrics for map-matching, routing, and route-following.
• Keep the quality signal fast and trustworthy: eliminate flaky tests, run sanitizer and performance builds, and track coverage.
• Build AI-driven test tooling: agent-based test generation, automated dogfooding and triage, and AI-assisted PR review.
• Partner with feature engineers on testability and review designs for how they will be verified.
• Thoughtfully leverage AI tools in your workflow and set the standard for how the team uses them.

What We Believe Are Important Traits for This Role

• 5+ years of experience in C++17: comfortable writing test code and tooling, reading production code, and debugging with sanitizers and profilers. Python or similar for harnesses and analysis.
• Proven experience building test infrastructure for a large native codebase: test frameworks, CMake, and CI systems.
• A data-driven mindset: you define metrics, build the tooling to measure them, and use them to argue for or against a change.
• Experience diagnosing hard-to-reproduce failures: flakiness, platform-specific behavior, memory and threading bugs.
• Strong English skills, with the ability to explain test results, risk, and trade-offs to peers and stakeholders.

Would be a Plus

• Familiarity with navigation concepts (map matching, dead reckoning, route progress, or Electronic Horizon).
• Experience with replay- or simulation-based testing using real sensor and GPS data.
• Hands-on experience building AI- or agent-based developer tooling for testing, code review, or triage.
• Experience with coverage tooling, performance benchmarking, or testing SDKs through generated bindings.

Employment Requirements

• Employment Type: Full-time
• Weekly Hours: 40 h per week
• Location/Hybrid Policy: Remote (from any city in Germany)
