Mechanical Airframe Systems Design Engineer – Landing Gear, Fuel, ECS, Hydraulics

About the role

The Mechanical Airframe Systems Design Engineer will lead the design, integration and validation of key mechanical systems for UAV platforms. This role combines advanced CAD modelling, analysis, and cross‑disciplinary collaboration to deliver high‑performance, airworthy solutions.

Key responsibilities

• Lead design, integration and validation of landing gear, fuel distribution, ECS, hydraulic circuits and actuation mechanisms for UAVs.
• Develop 3D CAD models, detailed drawings and manufacturing documentation using CATIA V5/V6, Siemens NX or SolidWorks.
• Perform structural, hydromechanical and thermal analyses to verify system integrity under operational loads.
• Collaborate with avionics, propulsion and flight‑control teams to ensure seamless system integration.
• Define system requirements, interface control documents (ICDs) and bill of materials (BOM) in line with aerospace standards (MIL‑STD, RTCA DO‑160).
• Support prototype builds, ground tests and flight trials, troubleshooting design issues in real time.
• Ensure compliance with airworthiness regulations and defense‑sector quality standards.
• Drive continuous‑improvement initiatives to enhance performance, manufacturability and maintainability.

Required profile

• Bachelor’s degree in Mechanical or Aerospace Engineering (Master’s preferred).
• Minimum 5 years experience in aerospace mechanical systems design, with expertise in at least three areas: landing gear, fuel systems, ECS, hydraulics, actuation.
• Proficiency in 3D CAD and PLM systems (CATIA, NX or equivalent).
• Strong knowledge of aerospace materials, manufacturing processes and GD&T.
• Experience with hydraulic/pneumatic system design, fuel system architecture and ECS thermodynamics.
• Familiarity with finite element analysis (FEA) and computational fluid dynamics (CFD) tools.
• Understanding of aerospace and defence standards such as AS9100, MIL‑STD and DO‑160.
