Senior Digital IC Design Engineer (AI / Compute) Cardiff Join a company who are building a next-generation design house focused on AI, advanced compute, and emerging semiconductor technologies. This is a rare opportunity to join at an early stage and define how digital design is done, technically and culturally. You’ll support and lead the development of AI and compute-focused ICs, working from architecture through RTL to silicon and have the opportunity to support and mentor the 6 graduates within the group. This role is well suited to someone motivated by the opportunity to give back to the industry sharing their experience, mentoring the next generation, and helping shape the growth of an emerging company.
