Lightmatter
Test Engineering Manager, Lightmatter
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.
Key Responsibilities
Define and implement test strategies for PIC characterization, validation, reliability, and manufacturing qualification.
Oversee the design, deployment, and scaling of automated test setups for optical/electrical validation, including probe stations, active alignment systems, and temperature‑controlled environments.
Own and drive program‑level milestones for test readiness, encompassing test plan definition, execution tracking, schedule risk mitigation, and cross‑functional alignment.
Engage with laser and integrated photonics design teams to establish design for test criteria and ensure efficient testability of device characterization DOEs and product designs.
Collaborate cross‑functionally with test, design, packaging, firmware, reliability, and systems teams to align test coverage with product and system‑level requirements.
Drive smooth transition of test flows from R&D to pilot and high‑volume manufacturing, including SPC implementation, yield monitoring, and process optimization.
Coordinate with external foundries, supply chain, and operations to align test capabilities with wafer/die delivery, production timelines, and sourcing constraints.
Establish test plans with external component suppliers and review test reports.
Manage relationships with capital equipment vendors, oversee tool procurement and calibration, and supervise outsourced test and reliability services as needed.
Lead and mentor a team of test engineers supporting laser and photonics test activities at wafer, die and package levels.
Required Qualifications
Master’s in Electrical Engineering, Applied Physics, Photonics or related discipline.
12+ years of experience in photonics test engineering.
5+ years of people management experience.
Demonstrated experience building and scaling automated optical/electrical test systems.
Proficiency in test automation environments (Python, LabVIEW, or similar).
Experience with program tracking tools (e.g., JIRA, Asana, MS Project) and engineering documentation management. Familiarity with reliability standards (e.g., Telcordia GR-468) and compliance (e.g., IEC 60825).
Strong analytical, organizational, and cross‑functional communication skills.
Experience in integrated photonics such as InP, SiPh, or hybrid platforms.
Preferred Qualifications
Experience collaborating with foundries and OSAT partners.
Knowledge of supply chain operations and contract manufacturer test integration.
