Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # UK - Fluid Systems Engineer - **Company:** Uk Orbit Fab - **Location:** Oxford, UK - **Contract:** Permanent contract - **Skills:** Systems Engineering, Hardware Design, Iterative and Incremental Development, Systems Analysis, Systems Development Life Cycle, Software Tools, Subsystems, Hardware Testing - **Published:** September 5, 2026 - **Apply:** https://startup.jobs/uk-fluid-systems-engineer-orbit-fab-9011780 ## About the Role We have described the skills, qualifications, and experience that would be valuable to the team, but you do not need to meet every criterion. Aptitude for solving complex technical problems, combined with practical experience designing, building, and testing hardware, is more important than any specific qualification, software tool, or career path., * Demonstrated experience developing fluid components or subsystems from requirements and concept through design, prototyping, testing, and key development milestones. * Demonstrated collaboration with space systems engineering teams * Experience developing verification plans and supporting or leading qualification, acceptance, or performance test campaigns. * Deep knowledge and experience in one or more of the following areas: * Fluid systems design and development * Fluid components design and development * Fluidic system analysis * Space systems engineering * Experience defining customer needs and crafting engineering requirements, including a proven ability to successfully push back on unnecessary or mission affecting customer requirements. * Excellent communication skills, both written and verbal * BS degree and three years of related engineering experience, or * MS degree in related field and two years of related engineering experience, or Ph.D. in related field NICE TO HAVE * Experience taking components or subsystems through the full development lifecycle, including flight operations. * Experience with fluid and thermal analysis tools such as EcosimPro, Thermal Desktop, Dymola, Modelica, or equivalent. * Experience with spacecraft propulsion systems and/or high-pressure fluid systems. * Understanding of the spacecraft propulsion and fluid component supply chain. * Experience developing both low-cost technology demonstrators and higher-budget flight systems. * Experience working in a fast-paced, multidisciplinary hardware development environment. * Experience working directly with customers, suppliers, and external technical partners. ## Description As a Fluid Systems Engineer, you will contribute to the development of the technologies and fluid systems that enable in-orbit refuelling. This includes fluidic components, subsystems, and the wider fluid and propulsion systems supporting Orbit Fab's refuelling missions. You will support early phase work as well as later phase development, integration, and testing through to acceptance and delivery. A strong candidate will call upon a breadth of experience developing components and subsystems in space propulsion and related fields, pursuing a hardware centric iterative approach to deliver on time and on budget. The successful candidate will bring broad experience in fluid systems, propulsion, or a related engineering discipline, together with a practical, hardware-focused approach to iterative development. You will work closely with engineers across the company and with external customers and suppliers to deliver robust technical solutions to challenging schedules and budgets., * Contribute to the definition and development of fluid system architectures for major UK and European in-orbit refuelling missions. * Develop preliminary and detailed fluid system designs, supported by appropriate analysis and modelling. * Support BD activities from an engineering perspective as required * Manage and maintain development schedules, systems requirements, and design budgets * Guide systems engineering processes and facilitate technical trades across the system * Support technical reviews and technical decision-making processes and development * Plan, specify and follow up simulations and test campaigns to verify subsystem and components performance and requirements compliance. * Lead hands-on build and testing of development models of components and subsystems * Support flight hardware AIT activities, qualification, acceptance testing, and delivery as required. * Identify technical issues and proactively implement resolutions to mitigate schedule and cost impacts * Identify suppliers and oversee component selection ## Related Videos - [What I learned as a developer from accidents in space](https://www.wearedevelopers.com/videos/642-what-i-learned-as-a-developer-from-accidents-in-space) - [Quantum Computing - The tiny and the big challenges](https://www.wearedevelopers.com/videos/934-quantum-computing-the-tiny-and-the-big-challenges) - [ Secure Code Superstars: Empowering Developers and Surpassing Security Challenges Together](https://www.wearedevelopers.com/videos/422-secure-code-superstars-empowering-developers-and-surpassing-security-challenges-together) - [10M Data Records Lost, Underwater Computing, and Psychedelic Fish - Matthias Geniar](https://www.wearedevelopers.com/videos/1908-10m-data-records-lost-underwater-computing-and-psychedelic-fish-matthias-geniar) - [The future of automotive mobility: Upcoming E/E architectures, V2X and its challenges](https://www.wearedevelopers.com/videos/374-the-future-of-automotive-mobility-upcoming-e-e-architectures-v2x-and-its-challenges) - [Old tools, new tricks](https://www.wearedevelopers.com/videos/1916-old-tools-new-tricks) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Software Engineer Salary in The UK](https://www.wearedevelopers.com/magazine/231-software-engineer-salary-in-the-uk) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [Frontend Developer Salary in The UK](https://www.wearedevelopers.com/magazine/233-frontend-developer-salary-in-the-uk) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [UK Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/326-uk-business-culture-and-etiquette)
