Job Description

About the role

We're a fast growing startup scaling from small, surge-built batches of our 1 metre ocean robots to continuous, high-volume production. Your mission is to "McDonaldise" our manufacturing: build processes so clear and robust that a new team member can be assembling C-Star parts confidently within an hour.

You'll ideally join in January, learn the ropes during our next fleet build, then lead production of our new concept design (small batch) and a larger 50-unit customer delivery over the following six months. You'll start as a team of one, with part-time builders, working closely with the executive and engineering teams to build a smooth, scalable production operation.

What you'll do

Own the full manufacturing lifecycle: sourcing, supplier management, QC, assembly, testing, and commissioning sea trials. Build and refine processes, SOPs, and quality controls that make production repeatable and teachable. Lead mechanical and electronics assembly, including 3D-printing workflows and post-processing, improving speed, repeatability, and cost as we scale. Balance one-off R&D builds with scalable production, and provide design-for-manufacture feedback into engineering. Build and lead a small production team, managing priorities and timelines. Early on, you'll be hands-on and building robots yourself. Contribute to high-level decisions on scaling strategy, facility layout, tooling and investments.

The Package

Salary: Competitive + meaningful stock options. We're open to a wide range of candidates and can reward compensation accordingly. Location: In person at our Plymouth waterfront office & workshop

Who you are

Organised and methodical. You take satisfaction in building clean, reliable processes. Experienced in hands-on hardware production: whether from a startup, marine yard, fabrication shop, or similar environment. Comfortable moving between the bench and the boardroom. You can build a fixture one day and present a scaling plan the next. Confident leading people: in a workshop, factory line, crew, or any practical environment. Curious and resourceful, with a builder's mindset and the drive to improve systems every time you touch them.

Why Oshen?

The ocean is still a blind spot for the planet, there's no persistent, wide-area sensing network. Solving this requires nodes that are mass-deployable, persistent, and navigable. Persistence means surviving multi-month missions through the worst winter storms. Navigability means reliably going from A?B or holding station. And mass deployment means units must be small, low-cost, and easy to field in swarms.

Oshen is the only company to have solved all three. Our one-metre ocean robots have completed multi-month missions, navigated autonomously at sea, and are the only surface robots in the world known to have sailed into, and survived, a Category 5 hurricane.

We're signing new contracts rapidly and expanding the team to meet demand. You'll be joining at an inflection point, where your work helps lay the foundations of a global ocean network that moves missions, customers, and climate science forward.
