Principal Research Engineer

Shape the Future of Sustainable Aerospace

We are seeking an exceptional Principal Research Engineer – Cryogenics to lead the development of next-generation cryogenic electrical power distribution systems for hydrogen-powered aerospace applications.

This is a rare opportunity to work at the forefront of sustainable aviation, driving MW-class cryogenic power technologies from early-stage research (TRL
1) through validation and system integration (TRL
6). You will play a critical role in defining technical strategy, influencing long-term technology roadmaps, and translating breakthrough research into certifiable aerospace systems.

As a technical authority in cryogenic systems, you will:

• Lead system architecture and component design for cryogenic-electrical power distribution (20K–70°C)
• Drive development of MW-class superconducting/high-current systems
• Own system requirements, safety assessments, and certification strategy (including DO-160 compliance)
• Define materials, design principles, and scalable technology solutions
• Lead validation, verification, and qualification activities
• Chair design reviews and provide technical governance across multidisciplinary teams
• Mentor engineers and grow internal cryogenic capability
• Shape and protect intellectual property aligned to long-term hydrogen propulsion strategy

• BEng (or equivalent) with 8+ years’ relevant experience
• Strong grounding in thermodynamics and mechanical principles
• Proven experience in cryogenic system development and integration
• Experience with superconducting or high-current power systems
• Understanding of material behaviour in cryogenic environments
• Experience across full product lifecycle (concept to certification)
• Knowledge of safety assessments, risk evaluation, and airworthiness requirements
• Ability to lead complex technical programmes and cross-functional teams

• Competitive salary + performance bonus
• Private medical and life assurance
• Flexible working hours (including early Friday finish)
• The opportunity to redefine aerospace power and propulsion
