As a Design Verification Engineer at Lightmatter, you will find yourself at the heart of a dynamic, interdisciplinary team. Your role will involve close collaboration with our digital design experts, using UVM testbench techniques to rigorously verify their designs. Your responsibilities will include working alongside photonic and analog designers, gaining a deep understanding of their innovative designs, and applying Real Number Modeling (RNM) and AMS verification methods. This critical function ensures the integrity of their work. We are hiring Design Verification Engineers at multiple levels.
Your interaction with the Architecture team will be crucial in comprehending system requirements and spearheading performance verification. This role offers a unique platform to enhance your skills across a spectrum of areas including UVM, AMS modeling, mixed-signal verification, formal verification, emulation, and both performance modeling and verification.
Responsibilities
- Engage collaboratively with teams specializing in digital, photonics, and analog design to develop comprehensive test plans.
- Design and implement UVM testbenches for both subsystem-level and full-chip verification. This includes debugging testbenches, resolving issues, achieving high coverage, and overseeing the final sign-off on Design Verification (DV).
- Develop Real Number Models (RNM) for photonics and analog circuits, conduct AMS verification in conjunction with UVM, and ensure precise model representation. Contribute significantly to the development of the Golden Reference Model (GRM) for design verification. Play an integral role in the execution of emulation and formal verification for DV purposes.
Qualifications:
- Bachelor’s degree in Electrical Engineering, Computer Engineering, a related field, or equivalent experience
- 12 years of design verification and SystemVerilog experience
- 2+ years of experience in python
- Expertise in developing the UVM library
- Experience with simulators such as Xcelium, ModelSim, Questa, or VCS
Preferred Qualifications
- Master’s degree or higher in Electrical Engineering, Computer Engineering, a related field, or equivalent experience with 8 years of design verification and Systemverilog experience
- Knowledgeable about assertion languages, power verification, reset-domain crossing verification, and AMS verification
- Strong problem solver, communicator, and team player with the ability to work with teams across multiple sites
- Ability to react to change and thrive in a fast-paced (startup) environment
- Communicates complex concepts effectively to diverse stakeholders, fostering support and consensus for initiatives
- Previous leadership experience
- 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

What We Do
Lightmatter is a startup photonics company that has pioneered a new paradigm in processor chip architecture that uses photons instead of electrons. Now the leader in the photonic AI compute “space race,” this new class of high performance semiconductors is the foundation of Lightmatter’s mission to enable the growth of computing, reduce harmful emissions associated with this growth, and democratize computing for all.
Lightmatter's technology accelerates critical operations in deep neural networks, using an array of programmable photonic elements fabricated alongside transistors in conventional computer chip fabrication processes. Our close-knit team of engineers has created an integrated photonics chip and ultra-high performance interconnect that is faster, more efficient, and cooler than anything else on earth (or anything ever experienced before) to power the next giant leaps in human progress.
