Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Automated Testing Module Lead - **Company:** Harmattan AI - **Location:** Paris, France - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Test Suite, Automation of Tests, C++ (Programming Language), Linux, Hardware-In-The-Loop Simulation, Python (Programming Language), Multi-Agent Systems, Reliability of Systems, GNSS, Docker - **Published:** September 18, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=f9f6726c3be549ae ## About the Role * Experience: 8+ years in automated testing, simulation-based validation, or test engineering for complex physical / hardware-in-the-loop systems (e.g., Autonomous Driving, Aerospace, Defense, Robotics). Scenario & Simulation Depth: Hands-on experience designing scenario-based test suites on a simulation platform and defining coverage that genuinely catches defects. This is the capability our current team lacks, and therefore the most valuable thing you can bring. * Technical Depth: Hands-on proficiency in Python, C++, Linux, Docker, and CI environments, with deep domain expertise in scenario design, SITL/HITL execution, and simulation tools. * Leadership & Ownership: Proven ability to step into an existing engineering team, establish immediate clarity, and manage distributed engineers (Paris and Lausanne) effectively**, including engineers more senior than you in years of experience**. * Validation Mindset: A rigorous, analytical approach to noisy physical metrics, false positives, and flaky test environments, instinctively questioning what a passing test proves. * Cross-Functional Diplomacy: Track record of defining and holding clear interfaces with platform providers and internal customer teams. Bonus: Background in defense/aerospace flight software, control systems, or experience closing sim-to-real fidelity gaps. * Location & Travel: Based in Paris or Lausanne, with travel between sites. Working- level English. ## Description As Automated Testing Module Lead, you take ownership of how Harmattan validates its autonomy and flight-software stack. Today, our software is validated mostly against real hardware, a process that consumes airframes, range time, and crew while sampling only a handful of nominal trajectories. The cases we actually build for, such as degraded GNSS, sensor dropout, electronic warfare, and multi-agent situations, are rarely reached economically that way. Your mission is to establish the scenario library, execution strategy, and interface bricks to turn our existing simulation platform into a fast, reliable, and continuous validation engine. This is a senior, hands-on technical leadership role. You inherit an active team of four engineers across Paris and Lausanne, with a target of around eight by mid-2027. Beyond leading the team, you become the technical authority on our scenario-based testing: defining what runs across SITL, HITL, and CI, holding critical technical boundaries with adjacent teams, and bridging the gap between simulation fidelity and real flight data. What You Will Do * Team Leadership & Strategy: Take over, structure, and give a clear mandate to our existing team of four engineers, while building the case and the roadmap to scale the module to around eight by mid-2027. Scenario & Simulation Engineering: Drive the design of a versioned scenario library covering nominal, edge, off-nominal, and contested flight conditions, expanding into Monte Carlo and multi-agent testing, and bring a team with no prior simulation experience up that curve. * Execution Strategy & Gating: Establish what tests run across SITL, HITL, and CI, defining gating policies, telemetry capture, deterministic replay, and coverage analytics. * Interface & Boundary Ownership: Negotiate, then maintain, strong, written technical boundaries with Tooling (who provide the simulation platform) and co-ownership splits with Validation (who define acceptance criteria and own final sign-off). * Sim-to-Real Correlation: Correlate simulation models against real flight data to continuously measure and close the sim-to-real gap, ensuring green test gates reflect real-world flight readiness., * Immediate Impact: Take over an established mandate with an existing team and pre-built simulation platform, delivering test capability in weeks rather than building from scratch. * High System Scope: Own the entire scenario library and execution strategy across our autonomy stack. Direct Mission Impact: Build test pipelines that directly accelerate the deployment of resilient autonomous systems in real-world defense environments. Cross-Functional Ownership: Work closely with Tooling, Validation, GNC, Perception, and Embedded SW teams to shape the future of flight-software reliability. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Are you still programming unit tests or already generating?](https://www.wearedevelopers.com/videos/722-are-you-still-programming-unit-tests-or-already-generating) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) - [How to add test automation to your project: The good, the bad, and the ugly](https://www.wearedevelopers.com/videos/1668-how-to-add-test-automation-to-your-project-the-good-the-bad-and-the-ugly) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers)
