Process Engineer (Propulsion)

Job description

**Help Build Europe's Hypersonic Capability** At **Hypersonica**, we’re redefining what’s possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast. By joining **Hypersonica**, you’re not stepping into a predefined role. You’re joining a talent dense environment where every individual shapes the direction of the company. Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously. We hire for talent, not rigid boxes. This role represents a business need, but the way it evolves will be shaped by the individual. If you’ve achieved what others said was impossible, or you bring a unique combination of skills that doesn’t fit a traditional mould, we want to hear from you. The work you do here directly contributes to Europe’s technological independence. ### What you'll do - Define the end-to-end manufacturing pathway for the rocket motor, from reception of hardware through to delivery of the completed motor, owning the process from first principles. - Plan the optimal sequence and layout of operations to minimise component waiting time and keep material flowing efficiently through the site. - Define how the manufacturing process remains compliant with safety legislation, establishing this early so it shapes the process rather than constraining it after the fact. - Apply Process Failure Mode and Effect Analysis (PFMEA), Control Plans, and Production Part Approval Process (PPAP) to build robust, repeatable manufacturing processes. - Own compliance to COSHH, ITAR, and COMAH within the manufacturing process design, working closely with safety, quality, and engineering teams. - Work hands-on across the shop floor, from early process trials through full-rate production, supporting build, troubleshooting, and continuous improvement. - Partner closely with propulsion, quality, and safety teams to ensure manufacturing processes are safe, compliant, and ready to scale. - Use production feedback to continuously refine processes, eliminate bottlenecks, and reduce risk. ### Who you are - A manufacturing engineer with experience in high volume manufacturing of explosive materials. - Experienced in Manufacturing Engineering within an ISO 9001 environment. - Skilled in PFMEA, Control Plan, and PPAP, and comfortable applying them to define new processes from scratch. - Experienced defining processes in compliance with COSHH, ITAR, and COMAH legislation. - Someone who understands how process design decisions show up in safety, throughput, and compliance, and designs accordingly. - Able to balance engineering rigour with startup speed, making sound decisions with incomplete data. - Motivated by building core capability from the ground up in a small team where your processes directly affect production success. - Energised by responsibility, ownership, and seeing your work move from concept to full-rate production. ### Security and Elibigility Requirement Due to the nature of the work with the UK MOD, applicants must be a British Citizen (or Dual UK national with British citizenship) and eligible for UK Security Clearance (SC) and, where required, Developed Vetting (DV) ### What we offer - A mission driven environment with the opportunity to work on one of Europe's most consequential defence challenges, with direct impact on sovereign capability and security. - Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow. - High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes. - A fast paced environment where good ideas are implemented quickly, and feedback from production drives real decisions. - A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly. - Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
