Jobs at Lightmatter

The Photonics Technical Lead develops scalable laser solutions for silicon photonics, collaborating with cross-functional teams and overseeing product design and validation.

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.

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.

Design and develop photonics architecture solutions for high-volume products, collaborate with engineering teams, and validate models through experiments.

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

Lead system-level electrical design for silicon photonics AI accelerators: define requirements, design power/memory/interconnect circuits, select components, oversee PCB layout and manufacturability, validate in lab, integrate cross-functionally, support manufacturing, and research new components and processes.

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 design verification for integrated digital, analog, and photonic devices using UVM, mixed-signal/AMS methods, RNM, and emulation. Define DV methodology, create reusable testbenches, run block and full-chip verification, integrate analog IP and behavioral models, close coverage and signoff, and collaborate with architects and designers for performance and post-silicon validation.

Implement complex digital blocks in advanced nodes (3nm) from synthesis through physical verification. Drive timing closure, power integrity, clocking, DRC/LVS cleanup, ECOs, manual layout, and collaborate with EDA vendors. Automate flows with TCL/Python/Shell and support tape-out readiness for high-performance ASICs, including silicon photonics integration.

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.

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.

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 and develop photonics components and subsystems for high-performance AI data center engines. Collaborate with cross-functional teams to deliver manufacturable designs, create and maintain documentation, support integration and testing, and drive technical solutions that impact performance, scalability, and product roadmap.

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.

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 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.

The role involves developing firmware for photonic products, collaborating across teams, defining architectures, and integrating with Data Center capabilities.

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

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