Automated Test-Bench Reliability Engineer, Wissous

About Us

Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.About the Role

The Automated Equipment Maintenance Engineer owns the reliability, uptime, and continuous improvement of our automated test bench infrastructure and production systems. Hands-on and technically deep, the role operates at the direct interface between manufacturing and engineering— commissioning and maintaining complex test benches, diagnosing cross-domain faults, and translating shopfloor observations into actionable engineering feedback. You will work daily alongside Test Bench, Automation, and Manufacturing Engineers, acting as the operational anchor that keeps systemsrunning while feeding structured technical insight back into the engineering cycle. Reports to the Plant Manager.Responsibilities

Test Bench Ownership&Maintenance Own availability and reliability of automated test benches— from commissioning and qualification through to day-to-day maintenance and recovery

Perform hands-on fault diagnosis across hardware, software, electrical, and integration layers

Execute commissioning, qualification, and requalification of test benches following upgrades, repairs, or configuration changes

Monitor bench health proactively— identify degradation before it impacts production throughput or test validity

Support test cycle time and station configuration improvement in close coordination with Test Bench Engineers

Engineering Team Integration Work directly and daily with Test Bench, Automation, and Manufacturing Engineering teams— the primary operational feedback loop between shopfloor and engineering

Support deployment and validation of software, hardware, and configuration updates on test benches and production equipment

Translate shopfloor observations— anomalies, failure patterns, recurring faults — into structured technical feedback for engineering and industrialisation teams

Participate in engineering reviews and deployment planning for new test systems, providing operational and maintenance perspective

Production&Factory Systems Maintain broader production infrastructure: automated storage, industrial PCs, scanners, and label-printing systems

Contribute to establishing a structured preventive maintenance system across test benches and manufacturing equipment

Coordinate and support on-site maintenance technicians as production scales

Candidate Requirements

Technical Background Experience in maintenance, test systems, or industrial automation— aerospace, defence, advanced electronics, robotics, or similar high-precision environments

Hands-on commissioning, maintenance, and troubleshooting of automated test benches or complex electromechanical systems— core requirement

Strong diagnostic capabilities across hardware, software, and electrical domains

Python, industrial software, or automation environments— meaningful advantage

Engineering Collaboration&Mindset Works closely with engineering teams— contributes technically to system improvement, not just task execution

Produces structured technical documentation: maintenance records, troubleshooting procedures, fault reports, and engineering feedback

Execution-driven, high ownership— proactive on fault detection, rigorous on prevention, comfortable in fast-scaling industrial environments

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
