Jobs at Lightmatter

The role involves architecting digital circuits for mixed-signal and photonic systems, collaborating with teams to design and validate high-speed architectures, and ensuring product readiness for market.

The engineer will architect wafer, package, and system level characterization and test strategies for silicon photonics products, and work closely with architecture and design teams, vendors, and validation teams.

Lead a team of test engineers to architect and execute wafer, package, and system-level tests for silicon photonics products. Define test concepts, drive test software and code-review standards, manage vendor and OSAT relationships, support high-volume manufacturing and reliability validation, and mentor engineers while aligning cross-functional teams on test requirements.

Design, layout, simulate, and test silicon photonic devices (couplers, muxes, rings, switches) and integrated laser systems. Collaborate with packaging, systems, and characterization teams to validate devices, troubleshoot performance, and optimize designs for manufacturability. Publish results and support product integration.

The Senior IT Support Engineer will provide technical support for Mac and Windows users, manage support tickets, administer cloud platforms, and maintain IT infrastructure while training users on security best practices.

Lead design of high-speed analog/mixed-signal transceivers for silicon photonics systems. Drive block specifications with cross-functional teams, run post-layout and mixed-signal simulations, validate circuits in lab, define test plans, document designs, and mentor junior engineers.

As a Design Verification Engineer, collaborate with digital, analog, and photonic designers to ensure robust design verification through methodologies, test plans, and performance validation.

Lead technical program management for silicon, packaging, assembly, and test from design through production. Drive planning, schedules, risk mitigation, cross-functional coordination, vendor/customer engagement, and milestone delivery for chip and interconnect products.

The Product Engineer will optimize manufacturing flows, manage yield and quality, lead cross-functional teams, and develop test strategies for semiconductor products.

The Staff Embedded Software Engineer will develop software for photonic AI processors and interconnects, collaborating with multidisciplinary teams, and integrating device software and firmware while debugging embedded systems.

Design analog and mixed-signal circuits for optical communication systems, collaborate with architects, and validate circuit performance in the lab.

Develop high-speed analog transceiver solutions while collaborating with architects and engineers for optical communication systems.

Lead technical writing for customer-facing content, ensuring quality and technical accuracy while collaborating with cross-functional teams. Manage documentation workflows and innovate with AI tools.

Define control plane architecture for photonic interconnect products and implement active laser control algorithms. Collaborate with a multi-disciplinary team and deliver embedded systems for extreme-scale AI clusters.

The Photonics Architect will design innovative photonics architecture solutions, collaborate with engineering teams, and validate models through testing and data analysis.

Lead hardware systems development for silicon-photonics AI accelerators and interconnects, owning PCB/board/system design through production, integration, verification, and cross-functional coordination while mentoring engineers and maintaining documentation and test/validation processes.

Lead the development of silicon photonics AI accelerators, focusing on system-level electrical design and integration with multidisciplinary teams.

Responsible for mechanical design and testing of hardware in AI server platforms, including CAD generation, collaboration with cross-functional teams, and quality management.

Own and grow major customer accounts across the full sales cycle. Build trusted relationships from engineers to C-suite, position Lightmatter solutions, coordinate cross-functional teams, forecast pipeline, lead negotiations, and close complex enterprise deals while expanding account footprint.

Lead transition of next-gen hardware from design to mass production. Oversee product lifecycle, supplier readiness, ramp management, schedule, and financial targets.
