Principal / Senior Mechanical Design Engineer - Drone / UAV (Engine Integration) - Hampshire - £65k

Description

This position will see you drive both concept and detailed design, ensuring engine systems are integrated safely and efficiently within airframes. You will play a key role in shaping innovative propulsion solutions that meet demanding aerospace performance, safety, and regulatory requirements.

An exciting opportunity for an experienced Senior or Principal Mechanical Design Engineer to take a lead role in the design and integration of powertrain systems into next-generation Unmanned Aerial Vehicle (UAV) platforms.

• Guide and mentor junior engineers while embedding best practice and continuous improvement.
• Produce CAD models and detailed technical drawings using SolidWorks and PDM tools.
• Conduct structural and vibration analyses using FEA; apply calculations for loads and stresses.
• Support prototype testing, validation, and documentation of integrated systems.
• Lead the design and development of UAV engine integration systems.
• Ensure compliance with aerospace standards and manage risk, cost, and schedule impacts.
• Packaging of ancillary systems (fuel, exhaust, electronics, wiring looms).
• Design engine mounts, vibration isolation systems, cooling baffles, cowlings, exhausts, and power take-off assemblies.
• Collaborate across disciplines including airframe, autopilot, manufacturing, testing, and quality assurance.

Requirements

• Experience in mechanical design, ideally within aerospace, automotive, or UAV sectors.
• Background in the design of rotating/reciprocating machinery such as combustion engines or transmissions.
• Expertise in SolidWorks (including PDM) with strong 3D CAD proficiency.
• Reduction drive brackets and power-take-off/propeller mounting solutions.
• Strong knowledge of materials, manufacturing, and processes including fabrication, machining, and casting.
• Excellent problem-solving, analytical, and leadership skills.
• Cooling solutions including cylinder/head baffles and airflow-optimised cowlings.
• Hands-on experience with FEA (structural/vibration analysis); CFD exposure beneficial.
• Degree (or equivalent) in Mechanical or Aerospace Engineering; further study or professional accreditation desirable.
• Passion for aerospace and UAV technology.
