We are looking for an experienced Propulsion Design and Test Engineer to join Orbex, this constitutes a highly versatile position which will expose you to most facets of liquid propulsion systems engineering. You will typically be responsible for the execution of individual work packages in close collaboration with senior engineers and technicians with activities ranging from all the way from conceptual design to qualification testing.

It is essential that applicants have both practical and theoretical experience in rocketry, it is likely that you have experience designing but also in robust testing procedures, ideally hot fire tests or similar.


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 €40m of project financing secured, a number of customers signed up, our 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 in space.

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.

Expected toolchain proficiencies will include:

• Highly experienced with SolidWorks or similar CAD tool.
• Numerical analysis tool (eg. Matlab/Simulink) proficiency.
• Experienced with typical rocket engine performance modeling tools (eg. CEA, RPA, Redtop etc.)
• Cycle simulation tool proficiency desired (eg. Ecosimpro, Simscape)
• MS Office tools, full proficiency expected
• Strong communication skills in both written and spoken English


You will have:

• A self-starter mentality, with minimum direction required
• A flexible and dedicated mindset
