We are seeking a talented and motivated ASIC Test and Characterisation Engineer to join a cutting-edge technology company revolutionising high-performance computing (HPC) and cloud computing. This role is pivotal in advancing ultra-low-power, high-bandwidth interconnect technologies with applications across industries such as camera sensors, autonomous vehicles, and aerospace. The company operates in both the UK and the US. Key Responsibilities: Bring up, debug, and characterise ASIC ICs on evaluation platforms. Develop and execute test plans and establish infrastructure for ASIC bring-up and characterisation. Provide input on evaluation PCBA designs to support comprehensive ASIC performance verification. Select test equipment and communication tools required for ASIC verification and characterisation. Collaborate with software developers to define and refine test software for ASIC debugging and characterisation. Analyse test results, diagnose issues, and refine test setups and procedures to enhance measurement accuracy and isolate functional or performance issues. Qualifications: Bachelor’s degree or higher in Electrical Engineering, Applied Physics, or a related field with 2 years of relevant work experience. Proficiency in standard communication protocols such as I2C, SPI, MDIO, and Ethernet. Strong knowledge of analogue communication circuits. Experience with RF design and testing using tools such as oscilloscopes, digital communication analysers, VNAs, optical power meters, and power supplies is highly desirable. Strong skills in lab automation scripting with Python are essential. Experience working with and programming microcontrollers and/or FPGAs is advantageous. A flexible, fast learner who thrives in a dynamic start-up environment. Familiarity with the physics of semiconductor devices (emitters and photodetectors) is an advantage. This is an excellent opportunity to contribute to breakthrough technologies shaping the future of high-speed, energy-efficient computing and communications
