Formal Verification Engineer

MatX's mission is to make the world's best AI models run as efficiently as allowed by physics, bringing the world years ahead in AI quality and availability. We build the full stack—from silicon and rack design through compilers, kernels, and ML models. We are seeking a Formal Verification Engineer to bring rigorous mathematical guarantees to our hardware and software at every layer of the stack.

Apply model checking and formal property verification to RTL blocks, memory subsystems, and interconnects, providing complete coverage wherever possible, using tools such as JasperGold or VC-Formal.

Develop and maintain machine-checked proofs for critical compiler transformations, ensuring correctness of lowering passes from our high-level programming model down to hardware

Build embeddings of our hardware description languages and simulator models into interactive theorem provers (e.g. Lean 4, Rocq, Isabelle/HOL), and use those embeddings to prove functional correctness and microarchitectural properties directly against the designs

Collaborate with architecture, compiler, and silicon verification teams to identify correctness properties worth proving and translate them into tractable proof obligations

Drive methodology for integrating formal tools (JasperGold, SymbiYosys, or equivalent) into our existing practices

Hands-on experience with hardware model checking—writing SVA/PSL properties, running bounded or unbounded proofs, and closing out formal verification targets at block or subsystem level

Practical experience with at least one interactive theorem prover (Lean, Coq, Isabelle/HOL, Agda, or similar)

Experience embedding an existing language or IR into a theorem prover—whether an HDL, compiler IR, ISA, or similar—is a strong plus
