Job summary

Lightmatter is seeking a Hardware Test Automation Engineer to advance automated test software for photonics chips and semiconductor devices. You will bridge bench hardware, ATE systems, and software to bring devices to life, from bring-up to production test.

Responsibilities include designing test software, maintaining test flows, and collaborating with hardware engineers to translate test requirements into repeatable, scalable solutions. Expect a hybrid workplace and competitive compensation.

Qualifications

• 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)
• 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.

Responsibilities

• Learn the hardware you're automating well enough to make informed software decisions about it.
• 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.
• Work directly with hardware and characterization engineers to understand their needs and translate device physics and test requirements into working, repeatable test software.
• Build 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 cause.
• Support test program releases to internal test cells and, at senior levels, to external test facilities.
• Communicate daily with the team on progress and blockers, and spend regular time in the lab working hands-on with hardware.
