Formal Verification Engineer

What You'll Do Here

• 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.

Who You Are

• 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.
• Experience with compiler correctness proofs or verified compilation (e.g. CompCert-style or translation validation) is a strong plus.
• Comfort working across the hardware/software boundary: you understand both RTL microarchitecture and compiler IR design well enough to find the correctness properties that matter.
• Able to work in a small team where the scope of what you own will be large and shift quickly.
