Subsurface Design Engineer

Senior Subsurface Design Engineer – Uncrewed Underwater Vehicles

• Lead the design of our next generation of underwater vehicles
• Relocation support available worldwide for the right candidate
• Mount Maunganui, New Zealand location

SYOS Aerospace is a fast-growing global robotics and aerospace company building advanced uncrewed systems across air, land and sea. We're looking for a senior engineer with a proven track record in underwater vehicle design to take technical leadership of vehicle development within our Subsea Vehicles team.

This is a senior, hands-on role. You'll set the design direction for our AUV, ROV and UUV platforms, guide other engineers, and own vehicles from first concept through to open-water validation. You'll be the person the team looks to on subsea design decisions.

The SYOS Way

We're a down-to-earth, collaborative team with a startup mindset: we move quickly, take ownership and turn ideas into real-world capability. Bureaucracy is minimal, your expertise will directly shape what we build, and no two days are the same. You'll join a small group of engineers who love hard technical problems and want someone experienced to help lead the way.

In this role you'll:

• Lead the design and development of AUV, ROV and UUV vehicle systems, from concept to deployment.
• Own the architecture of vehicle frames, structural components and pressure vessels.
• Make and guide key technical decisions on materials, hydrodynamics, propulsion and payload integration.
• Mentor and support other engineers, reviewing designs and raising the standard of the team's work.
• Lead prototyping, testing and field validation programmes.
• Work across multidisciplinary teams to integrate sensors, electronics and subsea systems.
• Help shape new vehicle concepts and the long-term direction of our subsea capability.

What you'll bring:

• 5+ years' experience designing underwater vehicles (AUVs, ROVs, UUVs or similar), with vehicles you can point to that you've taken from design into the water.
• Deep expertise in pressure vessel design, subsea materials and hydrodynamics.
• Strong knowledge of underwater propulsion systems.
• Advanced CAD skills (Solid Edge or similar).
• Practical experience with subsea cabling, wiring looms and PCB integration.
• Hands-on familiarity with CNC machining and 3D printing for prototyping.
• Experience leading technical work, whether formally managing engineers or acting as a lead on design projects.
• Sound engineering judgement and the confidence to make calls in a fast-moving environment.

Nice to have:

• CFD analysis for underwater vehicle optimisation.
• Offshore or marine operations experience.
• Open-water deployment experience with AUV/ROV systems.
• CAM programming.
