Job description

Mechanical Engineer (Design & Small-Series Production/Autonomy), Paris, France (90,000-130,000 EUR)

Mechanical Engineers sought for a well-funded, high-growth maritime & robotics scaleup developing autonomous marine and payload systems. We are seeking a hands-on Mechanical Builder to take full ownership of the vehicle’s physical structure and CAD design - leading the hardware from early prototyping through workshop assembly, field trials, and small-series production.

The company is developing high-speed, autonomous edge platforms designed to operate in complex, real-world environments. Its technology combines robust mechanical integration, watertight structural designs, and optimized sub-system packaging to deliver continuous operational capability without reliance on conventional infrastructure.

Ideally you will have experience performing engineering design in one or more of the following areas:

• End-to-End Mechanical CAD Design: Proven experience using Fusion 360 or SolidWorks for component sizing, functional dimensioning, structural architecture, and material selection.
• Sealed & Watertight Assemblies: Hands-on experience designing watertight enclosures, dynamic/static seals, cable penetrations, and hull interfaces for demanding environments.
• Multi-Disciplinary System Integration: Proven ability to account for thermal management, physical space constraints, vibration, and wiring harness routing in close collaboration with electronics and firmware teams.
• Manufacturing & Production (Preferred but NOT essential): Exposure to Design for Manufacturing (DFM), small-batch production transitions, supplier management for machining/fabrication, or establishing inspection methods.

Key Skills

Mechanical Engineer, CAD Design, SolidWorks, Fusion 360, Hardware Architecture, Subsystem Integration, Watertight Enclosures, Seals, Cable Penetrations, Structural Sizing, Material Selection, DFM, Design for Manufacturing, Prototyping, Workshop Assembly, Machining, Machined Parts, Small-Series Production, Field Testing, Robotics, Drones, Autonomous Systems, Defense Tech, Marine Systems
