Our photonic switching technology delivers the high-speed, ultra-low latency networking fabrics AI datacenters need and can’t get anywhere else. We’re a multi-disciplinary team of physicists, engineers, and machine learning specialists on a mission to remove the bottlenecks holding AI infrastructure back.\nJob Overview\nAs a Hardware Engineer at Salience Labs, you will play a crucial role in designing and testing the electronics that power our hybrid photonic-electronic systems. As an early member of the team, you will contribute directly to our mission of bringing photonic products to high-performance compute systems, particularly those used for AI.\nThe role offers a varied mix of system design, PCB design, system bring-up and qualification, with a significant share of hands-on lab work at our Oxford office.\nWhat you’ll be doing\nCarry out detailed hardware design, including specification, simulation, schematic capture (using Altium) and component selection. PCB layout experience is a strong advantage\n\nBring up and test new hardware in the lab, focusing on the electronics and how they interact with photonic elements\n\nDiagnose and resolve issues during hardware bring-up and testing\n\nCharacterise new electronic systems and their integration with photonic components\n\nCharacterise the mechanical and thermal properties of our systems and their impact on photonic performance\n\nQualify electronic systems for production, working with external test houses as needed\n\nWork closely with photonics, firmware and test colleagues to turn system requirements into hardware that works first time\n\nWhat we’re looking for\n3+ years of experience in high-speed digital or analogue design, including high-speed discrete analogue-to-digital conversion, high-performance FPGAs and high-speed digital interfaces (including Ethernet and DDR)\n\n3+ years of experience bringing up and testing new electronic systems\n\nStrong diagnostic skills, including hands-on rework\n\nComfort working both independently and within small, multidisciplinary teams\n\nStrong technical, organisational and time management skills, with the ability to translate requirements into successful hardware implementations\n\nDrive, motivation and flexibility to thrive in a fast-paced start-up environment\n\nExperience with PCB layout\n\nExperience working with external vendors for layout, manufacturing, assembly and qualification\n\nExperience characterising the mechanical and thermal properties of electronic systems\n\nThis is an \"on -site\" role with 4/5 days in the office required.","description_format":"text","description_chars":2649,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
