Field Service Lead

About the role

Harmattan AI builds autonomous and scalable defense systems and is expanding its teams after a $200M Series B. As Field Service Lead, you run the team that keeps deployed complex technical systems operational across customer sites. You own the maintenance program, the readiness of the deployed estate and the standards your team follows, and act as the senior escalation point for complex faults. This is a hands-on leadership role combining advanced technical depth with team coordination on the ground.

Key responsibilities

• Lead, schedule and mentor a team of Field Service Specialists across multiple customer sites, allocating resources and ensuring consistent, high-quality maintenance.
• Own the preventive and corrective maintenance program so systems stay at operational readiness.
• Define and maintain maintenance standards, procedures and checklists, and drive continuous improvement.
• Act as the senior point for complex fault diagnosis and corrective action, overseeing depot-level and sub-assembly repair capability.
• Own the spare-parts and sustainment model: availability, consumption tracking, reorder signals and obsolescence management, feeding reliability and failure-trend data back to engineering.
• Track and report system availability and maintenance status, resolving issues before they affect readiness.
• Oversee knowledge transfer and support to customer maintenance teams, and act as the link between field maintenance and engineering for recurring or systemic issues.

Required profile

• Substantial hands-on maintenance experience on complex electromechanical and/or electronic systems.
• Demonstrated experience leading or coordinating field service or maintenance teams; leadership is a hard requirement.
• Ability to lead complex fault diagnosis and oversee component and sub-assembly-level repair.
• Solid grasp of maintenance management: preventive programs, spares and sustainment, readiness tracking and procedure definition.
• Comfortable with hardware servicing and system software operations, including diagnostics, configuration checks and applying updates.
• Sound judgment under pressure, keeping a team effective and safe in austere environments, with a strong safety mindset.
• Comfortable with regular travel across customer sites; clearance eligibility and ability to meet confidentiality obligations.
• Proficiency in English is mandatory; French and Arabic are a plus.

Nice to have

• Experience in technical or industrial sectors maintaining complex equipment.
• Leading field service or sustainment teams in aerospace, heavy-equipment or similar high-tech sectors.
• Depot or repair facility setup and management experience.
• Train-the-trainer or customer enablement experience.
• Prior leadership in industrial maintenance or large-scale technical operations.
