Introduction Saab UK is part of Scandinavia's largest defence company, bringing together the best of Swedish and British innovation. Saab offers world-leading solutions and services in defence, aviation, space, and civil security to keep people and society safe. Our UK presence has been growing at pace, meaning we can offer a wide range of opportunities for personal fulfilment and career growth. We currently employ over 600 people across eight sites in the UK, and our specialisations include software engineering, underwater robotics, radars, AI, and armed forces training. The Role: This role will be a part of our Saab Seaeye business in Fareham. This can be a 12 month FTC. In this role you will take responsibility for the full-lifecycle design and development of bespoke power conversion and transmission solutions in line with the company's business needs through innovation, creativity and professionalism. As Lead Engineer you will act as Technical Authority for concurrent power projects: from in-house designs to outsourced specification and management. Key Responsibilities: The role seeks an engineer with excellent knowledge of power architectures, transmission, conversion and distribution, whilst having an appreciation for the real-world subtleties involved in creating robust and reliable power systems. You may be working on anything from large-scale power conversion products, efficient cabled transmission designs all the way through to motor drives and low voltage converters. Our voltages range from 24V to 5000V with powers from 500W to 250kW. You will be responsible for the successful design, implementation and delivery into our products.
