Help us build the satellites that will shape the future of space Open Cosmos is scaling – and we’re expanding our engineering team to match. As our new
Mechanical Design Engineer, you’ll take ownership of the mechanical design of our satellites, parts and ground support equipment (GSE). As well as mechanical design you will be dealing with suppliers and customers as well as the other Open Cosmos technical and project teams. When needed you will also support assembly and testing carried out by the Assembly, Integration & Test (AIT) team. This role involves a mix of desk-based work and hands-on work in our cleanrooms and labs. If you thrive in a fast-paced, mission-driven environment, have a keen eye for detail, and want to help solve some of Earth’s biggest challenges from space – we’d love to hear from you. What You’ll Be Doing Leading mechanical design activities across satellites, subsystems, and ground support equipment (GSE)
Producing models, assemblies, and drawings using CAD tools
Applying GD&T standards (ISO 1101, 2692 & 5458 or ASME Y14.5) to ensure precision and manufacturability
Collaborating with suppliers, customers, and project teams to ensure successful outcomes
Supporting satellite assembly and testing alongside our AIT (Assembly, Integration & Test) team
Authoring technical documents producing high-quality documentation including test and analysis reports
Working hands-on in our cleanrooms and labs as needed, with flexible remote working when possible
What You’ll Bring A solid background in mechanical design and manufacturing principles
Proficiency in 3D CAD tools and confident file management
Ability to provide hands-on involvement in cleanroom assembly and testing environments
Strong communication skills – written, verbal, and within multi-disciplinary teams
Ability to take ownership of tasks and collaborate effectively to deliver results
A quality-first mindset and a willingness to adapt in a growing, dynamic company
Why Join Us? You’ll work on real space missions with clear impact from day one
You’ll join a team of ambitious, curious people solving meaningful problems
You’ll be part of a collaborative culture with a flexible hybrid working model
You’ll help us make space data more accessible, affordable, and impactful
Where You’ll Work This is a hybrid role, with time spent at our Harwell site (UK) as required to support testing and build activities. You’ll also have flexibility to work remotely when lab presence isn’t needed. To apply, you must have the legal right to work in the UK. Sound Like Your Mission? Join us in building the spacecraft behind one of Earth’s most ambitious missions — making space data accessible to all.
