Principal Mechanical Engineer

Orbex has an exciting opportunity for a Principal Mechanical Engineer to act as a Technical Authority for the structural development and analysis of our launch vehicle, Orbex Prime.

You will take significant responsibility for flight structure development projects across technical performance, schedule and costs, taking a proactive role in the project from concept to manufacturing and launching flight hardware. For this role, experience in the design and analysis of finely toleranced flight structures for the space industry and/or composite structures would be extremely desirable, in particular Composite failure mode analysis and Launch vibration environments.

Orbex

Orbex is a leading micro-launch company with our Prime vehicle being prepared to launch from our home spaceport, Space Hub Sutherland. We are well placed to be one of the first operational micro-launch companies in Europe with over €122m of project financing secured, a number of customers signed up, launch licence application submitted, and backing from organisations including UKSA and ESA.

We are a rapidly growing company with staff located between our production and test facilities in Forres, Scotland and Copenhagen, Denmark. Working on cutting edge advances in rocket fuel technology, Prime’s carbon footprint is up to 96% lower than comparable vehicles, leading to innovations in propulsion and tank structures. A state-of-the-art re-flight system means we can recover and reuse our technology, and innovations in separation mechanisms mean we leave no debris on orbit.

Having developed in-house production capability, we can 3D print complex engines, produce full-scale carbon composite fuel tanks, and have avionics and software testing labs in both Scotland and Denmark. Based in Forres, you will be right in the heart of this fast-paced cutting-edge company, gaining a unique insight into what it takes to build a new launch vehicle for a buoyant commercial market.

Orbex is an Equal Opportunity Employer and is working towards a more diverse workforce in the aerospace industry.
