About Nexus Nexus is building a world supercomputer by leveraging the latest advancements in cryptography, engineering, and science. Our team of experts is developing and deploying the Nexus Layer 1, the Nexus Network, and Nexus zkVM in support of our mission to enable the Verifiable Internet. Nexus raised $25M in Series A funding, co-led by Lightspeed and Pantera, with participation from Dragonfly, SV Angel, and more. We are headquartered in San Francisco, and this role will be in-person with the rest of the Nexus team. Software Engineer - Formal Verification As a Software Engineer focused on Formal Verification, you’ll be responsible for ensuring the mathematical correctness of the Nexus system. You’ll work closely with the research, zkVM, and Layer 1 engineers to formally verify core components—from consensus mechanisms and cryptographic primitives to critical smart contracts. If you're someone who obsesses over catching bugs before they exist and thrives on rigor and precision, this role is for you. Responsibilities Apply formal verification to the zkVM, Layer 1 consensus, and core protocol libraries. Collaborate with cryptographers and engineers to model and verify core primitives. Analyze vulnerabilities in other protocols and proactively guard against them. Ensure correctness in a modular, evolving codebase without slowing innovation. Requirements Experience with proof assistants like Coq, Lean, Isabelle, F*, K, or equivalent. Familiarity with formal methods applied to blockchains, distributed systems, or cryptographic protocols. A deep curiosity about correctness and mathematical guarantees. Comfort working alongside research and engineering teams. Bonus Points Research experience in formal verification for cryptographic or blockchain protocols. Contributions to open-source formal verification tools. Benefits Competitive salary and generous equity compensation. Health insurance for employees and their dependents. Daily lunch and dinner provided at SF headquarters. Company-paid travel to events and conferences. Nexus is committed to diversity in our workforce and is proud to be an Equal Opportunity Employer (EEO). #J-18808-Ljbffr Nexus
