About the role
- This position requires access to information that is subject to U.S. export controls.
- MatX does not accept unsolicited resumes from individual recruiters or third-party recruiting agencies in response to job postings.
- No fee will be paid to third parties who submit unsolicited candidates directly to our hiring managers or People team, and any resumes submitted are deemed to be the property of MatX.
Responsibilities
- 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 directly against the designs
- Collaborate with architecture, compiler, and silicon verification teams to identify correctness worth proving and translate them into tractable proof obligations
- Drive methodology for integrating formal tools (JasperGold, SymbiYosys, or equivalent) into our existing practices
- Comfort working across the hardware/software boundary: you understand both RTL microarchitecture and compiler IR design well enough to find the correctness that matter
- Able to work in a small team where the scope of what you own will be large and shift quickly
Nice to have
- Hands-on experience with hardware model checking-writing SVA/PSL, 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
