Senior/Principal Mechanical Design Engineer Imagine being the go-to mechanical expert in a rapidly growing engineering team, trusted to make decisions, shape design culture, and bring technically innovative products to life. This is a unique opportunity to work on highly complex, high-spec electro-mechanical systems that push the boundaries of engineering. You will lead the mechanical design and development of products from initial concept through CAD modelling, testing, iteration, and production. You will remain hands-on, solving technical challenges creatively, applying your expertise, and mentoring others as the team grows. Autonomy is real in this role. You will be trusted to make decisions without red tape, balancing risk, speed, and quality, while collaborating with colleagues across electronics, software, and systems disciplines to deliver fully integrated solutions. You will see the full product lifecycle, designing entire systems rather than just components, and helping shape engineering standards for the future. The environment is start-up in spir...
