Mechanical Engineer – UAV Airframe Design

About the role

Harmattan AI is building autonomous defence systems and is looking for a Mechanical Engineer to join its Airframe team. You will be responsible for designing and prototyping UAV platforms and subsystems, taking projects from concept through production while ensuring performance, reliability and manufacturability.

Key responsibilities

• Design and prototype UAV airframes and complex mechanical subsystems from scratch.
• Own system‑level constraints such as thermal management, mass budget, cost of goods sold and environmental sealing.
• Collaborate with electrical, software and industrialisation teams to integrate sensors, payloads and electronics.
• Conduct stress and failure analysis, develop test benches, calculation sheets or scripts for validation in extreme environments.
• Manage delivery packages and technical specifications, meeting tight deadlines.
• Oversee manufacturing with suppliers, focusing on plastic injection moulding and precision machining.
• Maintain accurate 2D/3D documentation and the “source of truth” in Confluence.

Required profile

• Master’s degree in Mechanical Engineering, Aerospace Engineering or a related field.
• Proven experience designing and prototyping mechanical systems, preferably for UAVs, robotics or defence.
• Strong written and verbal communication skills and ability to lead cross‑functional discussions.
• Full commitment to Harmattan AI’s mission and willingness to go the extra mile.

Required skills

• Proficiency with CAD software (SolidWorks).
• Experience with structural and thermal analysis tools (FEA).
• Knowledge of high‑precision machining processes.
• Understanding of plastic injection moulding.
• Familiarity with Confluence for documentation.
