Senior Electronics Engineer
Job Description At Sportable, we're not just redefining the future of sports technology; we're creating it. As a leading sports data provider, we've pioneered world-first innovations such as our range of Smart Balls, and we continue to expand into new sports and new markets. Our products combine cutting-edge embedded systems, wireless technology, and cloud-based platforms. We are looking for a Senior Electronics Engineer on a fixed-term contract basis to design the electronics for our ball and player tag products, from architecture through to production. This is a hands-on, senior design engagement at the centre of our hardware roadmap as we scale into Premier League Soccer and American Football NFL. Role Overview You will design the electronics for a new generation of instrumented ball and player tag, working alongside our Principal Hardware Engineer, who holds design authority, together with our Mechanical Technical Lead and our Embedded Firmware team. This is a design engagement with genuinely hard constraints. The electronics live inside a ball and inside player tags and hit hard as a matter of normal use. Every cubic millimetre, every gram and every milliwatt is contested. If you like problems where power, radio, mass, mechanical envelope, manufacturability and certification are all pulling against each other at once, this is that job. Scope The engagement is structured based on hours worked. You provide the effort estimate for each phase, we accept it in writing, and that is the basis for that phase. Key Responsibilities Architecture & Design Design the architecture for a sealed, wirelessly charged, battery-powered product: power and energy budget, charging approach, radio and antenna strategy, sensing and data-offload. Decompose product-level requirements into electronic requirements, and state the assumptions behind the decisions. Lead schematic design and PCB layout for high-performance, low-power embedded systems (Altium). Wireless & EMC Lead on inductive charging, radio integration and electromagnetic compatibility, including designing the certification route in at concept stage rather than discovering it at the test house. Integrate antenna solutions on real boards: work to vendor and simulation inputs, tune the match, and measure rather than assume. Validation & Bring-Up Support bring-up of your own designs on site, and validate in the lab and in live field environments with real teams and real athletes. Report measured behaviour against the design intent, including where the board deviates from it. Design Records & Review Capture design intent, the alternatives you considered, and why you rejected each one, so our team can extend the design without you. This is a deliverable, not a courtesy. Take part in design reviews and track findings through to verified closure in the released files. Manufacturing & Lifecycle Design for manufacture and test from the start. Produce the fabrication and assembly pack a...
