About the role
- The company invented the world's first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.
Responsibilities
- Design and build test software that automates device bring-up, characterization, and production test sequences across bench and ATE environments.
- Develop 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 role.
- Build and maintain data logging and results pipelines so test data is captured accurately and usable downstream (metric computation, yield analysis, production handoff).
- Support test program releases to internal test cells and, at senior levels, to external test facilities.
Requirements
- Bachelor's degree in Computer Science, Electrical Engineering or related field.
- 8+ years of experience in hardware test software, ATE systems, or test architecture, ideally in semiconductor or photonics.
- Track record of owning test software architecture for a product line, including decisions on how the framework scales across projects and teams.
- Deep 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 others.
- History of mentoring engineers and driving cross-functional technical decisions with hardware, characterization, and manufacturing teams.
- Can articulate, end to end, how they scoped, planned, implemented, and validated an automation project.
- Comfortable 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 it.
Nice to have
- Master's/PhD with 3+ years, of experience in hardware test software, ATE systems, or test architecture, ideally in semiconductor or photonics.
- Experience integrating ATE with wafer-level hardware (probers, handlers) is a strong plus.
- Experience with photonic test instrumentation
Skills
- Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress.
- Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion.
- Lightmatter is (re)inventing the future of computing with light!
