Location: San Jose, CA
Company: Ayar Labs
**Engineer: Silicon Validation** Location: San Jose (on-site) Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models. Backed by industry giants like NVIDIA, AMD and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next-generation AI scale-up architectures. In this role, you will own the silicon bring up and validation of our optical chiplets. You will execute post-silicon bringup and characterization across SerDes, photonic, and mixed-signal blocks, building the test infrastructure and automation that ensures our products meet and exceed specification before customer deployment. **Essential Functions** - Perform initial power-on and bringup of new silicon tape-outs, including boot sequence validation, clock/power domain verification, and initial functionality tests. - Perform functional and electrical characterization of high-speed SerDes interfaces, photonic control blocks, and mixed signal blocks. Define and execute test plans at both block and chip level. - Use lab test equipment (BERT, oscilloscope/DCA, OSA, signal generators) to characterize signal integrity, eye diagrams, BER, jitter, and optical performance metrics. - Develop and maintain Python-based test scripts and automation frameworks for regression and characterization testing. - Systematically investigate silicon anomalies and failures; collaborate with design and firmware engineers to develop and verify fixes. - Write clear test plans, validation reports, and signoff documentation; communicate findings to cross-functional teams. - Partner with firmware, analog/mixed-signal, digital, and systems engineering teams across the full product development cycle. **Basic Qualifications** - Bach
