OverviewAt LEX, where engineering and biology meet to create technologies that push boundaries, we need an R&D Test & Development Engineer, or as we like to call you, the person with the R&D hat on who makes things work... Whether it's setting up an experiment, building a fixture, or digging into data, you'll be the one who ensures ideas turn into reliable results.You will be central to our R&D process. Testing, troubleshooting, and refining both full systems and subcomponents. Your work will provide the data and practical solutions that keep development moving forward. ResponsibilitiesPlanning and performing structured tests to characterise performanceCollecting, analysing, and presenting experimental data in clear, actionable reportsDesigning and assembling prototype test fixtures (mechanical, electrical, and software)Using Python, LabVIEW, or similar tools to acquire, manipulate, and present data (e.g. cameras, serial comms, TCP etc)Developing expertise in cartridge/instrument test workflowsSupporting and maintaining the LEX database and associated software toolsWorking closely with engineering, software, and biology teams to make sure systems deliver in practice, not just in theory RequirementsWe are looking for a practical problem-solver. Someone who thrives on making complex systems work, and not just on paper. You'll enjoy working across multiple disciplines and be quick to adapt and learn new approaches when the situation demands it.You may view yourself as an engineer or a scientist, but you do have to be comfortable running experiments as well as critiquing your findings; not just "turning the handle". We believe this role sits somewhere in the range between a ‘Technician +’ level up to ‘Engineer' level.
