Job details

Posting language: English
Posted: Oct 8, 2026

Original job description

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. 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.

Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!

If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.

Lightmatter is (re)inventing the future of computing with light!

At Lightmatter, an SDET is a software engineer first , not a QA coordinator or manual tester. You'll design and build the frameworks, harnesses, and hardware-in-the-loop infrastructure that let firmware engineers test their own code continuously on real photonic hardware. You'll sit with the firmware team, spend time at the bench with oscilloscopes, debuggers, and optical instruments, and serve as the bridge between firmware and broader software and systems organizations.

Responsibilities

Own the architecture and roadmap of the firmware test automation framework across products, targets, sites, and teams
Design and build stable automation for new firmware features and hardware, held to production-quality engineering standards
Build and operate HIL test infrastructure: bench and rack fixtures, device farms, power/reset control, instrument integration, and CI orchestration on real photonic hardware
Define test strategy, plans, and reporting; lead test plan reviews across teams
Integrate firmware testing into CI/CD so every change is built, flashed, exercised on hardware, and reported automatically
Own framework reliability and flaky test metrics as first-class engineering problems
Build results, telemetry, and log pipelines for triage, trend analysis, and release decisions
Debug failures across the full stack (firmware, board, instrument, fixture, test code) and partner with engineers to resolve them
Participate in firmware design reviews to influence testability and diagnostics early
Integrate with data center management interfaces (CMIS, OpenBMC, DMTF); debug embedded systems using GDB, JTAG, and logic analyzers
Define diagnostics and monitoring architecture for photonic transceivers
Mentor engineers on test architecture and write clear documentation for non-specialists

Qualifications

8+ years of professional software development, primarily on embedded products, including designing test frameworks and infrastructure
BS or MS in Computer Science, Electrical Engineering, or equivalent experience
At least one automation framework or HIL system architected and built from scratch, adopted by other engineers, and in daily use and the ability to discuss its design, tradeoffs, and lessons learned
Strong Python: fixture and abstraction layers, hardware drivers, plugin/configuration architectures
Working fluency in embedded C/C++: able to read firmware drivers or state machines and write tests for edge cases
Experience owning CI/CD pipelines running tests on physical hardware (GitHub Actions, GitLab CI, Jenkins, or equivalent), including runner health, hardware allocation, and recovery
Track record of delivering robust automation under fast-changing requirements and hardware

Preferred Qualifications

PhD, or MS with 8+ years in embedded test automation or firmware development
Experience testing firmware for optical transceivers, photonic systems, or precision analog/mixed-signal hardware
Familiarity with CMIS, OpenBMC, or DMTF/Redfish
Experience with Pytest ecosystem and test tooling for Zephyr or FreeRTOS (Twister, ztest, Renode, QEMU, or similar)
Experience with optical and electrical test and measurement equipment
Startup experience
Thoughtful use of AI-assisted tools in test generation, triage, or analytics

Benefits

Comprehensive Health Care Plan (Medical, Dental & Vision)
Retirement Savings Matching Program
Life Insurance (Basic, Voluntary & AD&D)
Generous Time Off (Vacation, Sick & Public Holidays)
Paid Family Leave
Short Term & Long Term Disability
Training & Development
Commuter Benefits
Flexible, hybrid workplace model
Equity grants (applicable to full-time employees)

Benefits eligibility may vary depending on your employment status and location. Lightmatter recruits, employs, trains, compensates, and promotes regardless of race, religion, color, national origin, sex, disability, age, veteran status, and other protected status as required by applicable law.

Export Control

Candidates should have capacity to comply with the federally mandated requirements of U.S. export control laws.

Responsibilities

You will design and build firmware test automation frameworks and hardware-in-the-loop infrastructure to ensure continuous testing on real photonic hardware. You will also integrate these tests into CI/CD pipelines and collaborate with firmware engineers to debug failures across the full stack.

Requirements

Candidates must have 8+ years of professional software development experience, primarily in embedded systems, with a strong background in Python and C/C++. A bachelor's or master's degree in Computer Science, Electrical Engineering, or equivalent experience is required.
