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 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, post-silicon validation formal verification, emulation, and both performance modeling and verification.
Responsibilities
- Define and enhance the DV methodologies required for integrated digital, analog, and photonic devices with a strong emphasis on emulation for design verification.
- Create and execute test plans to ensure high-quality tapeouts that meet functional and performance goals, while leveraging emulation where appropriate.
- Collaborate with architects, DV engineers, digital designers, and analog/photonics designers to define validation flows.
- Create reusable and scalable test bench components that enable efficient and effective verification.
- Close coverage and finish all DV signoff requirements, with a focus on leveraging mixed signal simulations to achieve high coverage metrics
- Work on block level and full chip design verification.
- Integrate analog design IPs from vendors and internal teams and develop verification environments for simulation and emulation.
- Work with analog design engineers to create behavioral models for analog designs and with digital design engineers to integrate models/testcase/checkers into upper levels
Qualifications
- Bachelor’s degree in Electrical Engineering, Computer Engineering, a related field, or equivalent experience
- Minimum of 8 years of design verification and SystemVerilog experience
- 2+ years of experience in Python
- Expertise in developing with the UVM library
- Experience with simulators such as Xcelium, ModelSim, Questa, or VCS
- Strong problem solver and collaborator
Preferred Qualifications
- Master’s degree or higher in Electrical Engineering, Computer Engineering, a related field, or equivalent experience with 6 years of relevant experience
- Experience with post-silicon validation and debug
- Experience with AMS verification
We offer competitive compensation. The base salary range for this role determined based on location, experience, educational background, and market data.

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.
