Skills and Experience * Six Sigma black belt Team R&D Engineering Location Cambridge Contract Permanent (Full time or part time) About CGD A spin‑out of the University of Cambridge, CGD is a fabless semiconductor company that develops energy‑efficient GaN‑based power devices to make greener electronics possible. The global power semiconductor market is expected to exceed $50BN. CGD has secured seed, Series A and B funding, and four projects funded by iUK, BEIS and the EU. The team’s technical and commercial expertise has been fundamental in early market traction of our proprietary technology. We pursue innovation to address the world’s most significant challenges—energy consumption and CO₂ emissions—by delivering sustainable power solutions. With a mindset of pushing semiconductor limits and an outstanding team of worldwide experts, we engineer green solutions that respect natural resources and support a more sustainable future. The Opportunity This is an amazing opportunity to join CGD at an early stage and lead the test and reliability engineering team as it grows in size and capability. The team is responsible for the test, characterisation, and reliability of CGD’s leading‑edge GaN products. The Senior Test and Reliability Manager will manage team day‑to‑day operations, provide technical and personal leadership, and serve as a senior engineer. As line manager and senior engineer, you will work as a hands‑on member while leading other engineers, collaborating with other CGD groups to ensure timely delivery of projects. The role offers a chance to shape industry direction as GaN technology transitions to high‑volume production, impacting future test standards through CGD’s involvement with the JEDEC group. You will report directly to the VP R&D and work closely with senior management daily. The role is based at our office and lab in Cambridge, UK, with occasional travel required. Main Responsibilities * Design and execute device reliability characterisation experiments of GaN power ICs * Develop characterisation strategies and test planning (DOE) * Develop GaN device reliability models * Develop new test methods for GaN‑IC reliability * Write reliability‑specific application notes and white papers * Lead reliability aspects of Technology R&D and Product R&D projects * Design and run customer‑specific tests * Lead TCAD and multi‑physics simulation projects for reliability insight * Liaise with electrical engineers for the development of reliability characterisation systems * Manage the team of test and reliability engineers focused on characterisation, lifetime and reliability, and test hardware infrastructure * Manage resource allocation for test and reliability activity across current CGD projects Requirements Essential * Degree in Electrical Engineering or a similar technical subject * Demonstrable experience in test engineering, ideally including device reliability and characterisation * Strong experience managing an engineering team, ideally within a power semiconductor or power electronics environment * Basic knowledge of wide bandgap semiconductors * Experience working with customers * High self‑motivation with a results‑oriented approach * Excellent communication skills and motivation to collaborate with multiple stakeholders * Experience in managing and leading technical teams * Expert knowledge of power semiconductor device reliability, preferably GaN * Strategic thinker with practical skills and experience * Inspirational confidence in colleagues, partners and customers * Comfortable in a fast‑paced start‑up environment * Pro‑active nature, responsive to changing needs of the projects and business * Strong communication and presentation skills, including writing white papers and application notes and presenting technical topics to an audience * Mindset for precise and high‑quality results * Eye for detail Desirable * Experience measuring/characterising devices and AC/DC or DC/DC converters * Comprehensive knowledge of wide bandgap semiconductor device physics, preferably GaN power devices * Skills in power electronics, especially circuits for reliability testing * Experience with finite element modelling (TCAD and multi‑physics) * Experience with semiconductor failure analysis * Knowledge of power device packaging technologies and their reliability aspects * Project management qualifications * Six Sigma black belt Benefits * Excellent salary * Share options scheme available (ownership of company) * Pension scheme (6% company contribution) * Life assurance (3x salary) * Medicash cash plan * Flexible working options (both location and times) * Annual leave allowance of 33 days (including bank holidays) * Training and career development * Family friendly policies * Cycle to work scheme * EV leasing scheme * Volunteer leave policy * IP bonus scheme * Involvement in collaborative projects and grants with the University of Cambridge and other partners * Recruitment referral bonus * Regular social events including frequent company lunches, annual summer party, Christmas party, team building and wellbeing activities We believe in equal opportunities We are committed to providing equal opportunities to all current and prospective employees regardless of age, disability, sex, sexual orientation, pregnancy and maternity, race or ethnicity, religion or belief, gender identity, or marriage and civil partnership. We aspire to have a diverse workforce because diversity enables better business outcomes. From application to interview, we place inclusion at the heart of all we do. We are well set up for collaborative hybrid working, with some team members working in the UK office and others from home in the UK and other cities in Europe and Asia. #J-18808-Ljbffr
