What they need
Want to take your fluid systems experience and apply it to hardware that will actually operate in space?
Read the overview of this opportunity to understand what skills, including and relevant soft skills and software package proficiencies, are required.
We are supporting a growing space technology business at Harwell that is developing innovative spacecraft hardware for future in-orbit operations.
They are looking for a Fluid Systems Engineer to join their engineering team and take a hands-on role in the development of fluid systems and hardware from initial requirements and design through to manufacture, integration and testing.
You do not need to already work in the space sector.
We're particularly interested in engineers from aerospace, propulsion, automotive, energy or other advanced engineering environments who have genuine experience designing and developing pressurised fluid systems and would like to bring that experience into the space industry.
What you'll be doing
You'll Be Involved Across The Engineering Lifecycle, Including Fluid system architecture, design and development
Requirements definition and engineering calculations
Selection and integration of components such as valves, regulators, pumps, tanks, pipework/tubing and instrumentation
Pressure, flow and pressure-drop calculations
Supporting component specification and supplier selection
Developing and testing prototype hardware
Supporting manufacture, assembly and integration
Planning and conducting system/component testing
Troubleshooting and resolving hardware issues
Working closely with mechanical, systems, test and other engineering disciplines
What we're looking for
Ideally you'll have around 4–5+ years' relevant engineering experience and a strong practical understanding of fluid systems.
Experience Could Come From Areas Such As Fluid systems | Hydraulics | Pneumatics | Propulsion | Fuel systems | Thermal/fluid systems | Pressure systems | Gas handling | Cryogenics | Process systems
You'll ideally be comfortable taking engineering problems from analysis and calculation into real, testable hardware.
Previous space-sector experience would obviously be useful, but it is not essential. We're much more interested in somebody who genuinely understands fluid systems and wants to apply that knowledge to spacecraft hardware.
This could be a particularly interesting opportunity for an engineer who has looked at the space sector from the outside and wondered how to make the move.
