About Athanor

We build Kairos, a verification engine that proves or disproves computational claims with formal methods. Our customers are hardware teams, accelerator developers, and infrastructure engineers whose designs have to hold up to scrutiny, not just pass a testbench.

We are a small, technical team where every engineer ships across the full stack. There is no distinction between "research" and "production" here. You will write Rust that runs in CI, Lean proofs that gate customer releases, and Python orchestration that coordinates multi-engine verification campaigns.

What we look for

• Strong backend software engineering: you write clean, tested, production-quality code
• Rust experience: systems-level thinking, ownership model, no-panic production code
• RTL design knowledge: Verilog/SystemVerilog, synthesis, timing closure, gate-level reasoning
• EDA tooling familiarity
• Accelerator kernel development: NKI, CUDA, HLS, or similar hardware-targeted programming
• Comfort with formal methods: model checking, theorem proving, or equivalence checking (practical, not just theoretical)

Nice to have

• Networking systems experience: congestion control, protocol verification, eBPF
• Lean 4 or other proof assistant experience
• Experience with Verus, Dafny, or other verified systems languages
• Prior work at an EDA company, chip design team, or hardware verification group
• Contributions to open-source EDA or formal verification tools

How we work

• Small team, high autonomy, fast iteration
• Every engineer owns features end to end: design, implement, test, ship, support
• Heavy emphasis on correctness: property-based testing, mutation testing, formal proofs, CI gates that reject regressions
• Lean codebase discipline: complexity ratchets, no-scaffold rule, quality bar rises with every PR
• Direct access to founders and customers
