Role

Who you are

Currently enrolled in a graduate engineering program, preferably in an ECE, EE or Computer Engineering degree
Relevant
Proficiency in Hardware Description Languages (HDL) such as SystemVerilog
Knowledge of verification methodologies such as UVM
Proficiency in using simulation tools like Xcelium, ModelSim, Questa, or VCS
Experience with Scripting Languages (perl or python)
Strong problem-solving skills to identify and resolve issues in the design
Exposure to AMS verification
Exposure to formal verification
Fluency in English, both written and verbal
Ability to work with diverse teams of engineers and scientists

What the job involves

We are hiring an intern for our Design Verification team at Lightmatter! Lightmatter has created a solution in photonic computing: using photons instead of electrons to take advantage of their higher bandwidth
Collaborate closely with digital, photonics, and analog designers to gain a thorough understanding of their designs and formulate comprehensive test plans for verifying their work
Create UVM test benches for subsystem-level verification and provide support for full-chip verification. Debug test benches, identify and address issues, achieve high coverage, and ultimately sign off on Design Verification (DV)
Develop Real Number Models (RNM) for photonics and analog Intellectual Properties (IPs) and conduct AMS verification to ensure accurate model representation. Integrate the RNM models seamlessly into the UVM test bench

Our take

Neural networks and CPUs are vital to AI solutions, but manufacturers have largely failed to maintain innovation in recent years. Lightmatter solves this problem by offering a next-generation computing platform powered by photonics (light waves).

Lightmatter offers a forward-facing platform for AI-building that acts as an alternative to traditional solutions. It works by replacing wired CPUs with a combination of photonics and new algorithms. Lightmatter's solution is not only faster, but it is considerably more sustainable, and it has the potential to drive the next generation of AI development.

As of 2025, Lightmatter has raised $850 million across six funding rounds and grown to a staggering valuation of $4.4 billion, a testament to growing industry demand for faster, more effective AI-building solutions. Lightmatter currently has three products on the market - Envise, Passage, and Idiom - and is poised to take on the incumbent chiplet industry with a photonics-based alternative.
