Staff / Senior Staff Hw Test Automation Engineer

Product Engineering builds the software that brings up, characterizes, and qualifies Lightmatter’s photonic chips on real hardware — from bench-top bring-up through production test on automated test equipment (ATE). You’ll write the code that drives instruments, testers, wafer probers, and lab automation to bring a chip to life and prove it works. Test software infrastructure at Lightmatter spans multiple platforms, wafer test, hardware validation, and laser/optical test, and this role often acts as the bridge between engineers working at the bench and the broader test software teamAs a Hardware Test Automation Engineer you’ll have the opportunity to work across some combination of: an internal test software framework (Java/Python-based), industry-standard ATE test method and testflow development, wafer prober integration, instrument control (optical and electrical sources, meters, sensors), embedded/firmware interfaces on the hardware side, and data pipelines from lab equipment to structured resultsLearn the hardware you’re automating well enough to make informed software decisions about itDesign and build test software that automates device bring-up, characterization, and production test sequences across bench and ATE environmentsDevelop and maintain test methods, test flows, and instrument control code depending on level and project while writing code and reviewing code are both daily parts of the roleWork directly with hardware and characterization engineers to understand their needs and translate device physics and test requirements into working, repeatable test softwareBuild and maintain data logging and results pipelines so test data is captured accurately and usable downstream (metric computation, yield analysis, production handoff)Debug test hardware/software integration issues, working across the device under test, the fixture, the instrument, and the test code to find root causeSupport test program releases to internal test cells and, at senior levels, to external test facilitiesCommunicate daily with the team on progress and blockers, and spend regular time in the lab working hands-on with hardwareBenefits
Commuter benefit401(K)Happy hour -Spend time together and build friendshipsGenerous vacation policy and holidaysOpportunity to learn from your peers and teach them what you know across electronics, photonics, machine learning, and moreHistory of mentoring engineers and driving cross-functional technical decisions with hardware, characterization, and manufacturing teamsCan articulate, end to end, how they scoped, planned, implemented, and validated an automation projectTrack record of owning test software architecture for a product line, including decisions on how the framework scales across projects and teams8+ years of experience in hardware test software, ATE systems, or test architecture, ideally in semiconductor or photonicsDeep hands-on experience with ATE test method/test flow development and/or embedded test frameworks for hardware test automation, plus fluency with instrumentation automation (SCPI/VISA or equivalent) at a level where you can teach it to othersBachelor’s degree in Computer Science, Electrical Engineering or related fieldComfortable working at the hardware/software boundary — reading and reasoning about embedded software (C/C++), controls, or firmware well enough to co-develop directly with the engineers who own itMaster’s/PhD with 3+ years, of experience in hardware test software, ATE systems, or test architecture, ideally in semiconductor or photonicsExperience integrating ATE with wafer-level hardware (probers, handlers) is a strong plusExperience with photonic test instrumentation
