Tech Lead Engineer
Nexus is developing a Layer 1 blockchain designed to function as a 'world supercomputer' for the AI era. By leveraging a zero-knowledge virtual machine (zkVM), Nexus aims to provide a high-performance, scalable, and verifiable compute platform. Users can contribute their device's idle compute power to the network and earn rewards, facilitating mass adoption. The project is focused on building infrastructure for autonomous applications and agentic intelligence.

About Nexus Laboratories, Inc.
Nexus is a technology company building infrastructure for the AI era. Their core products include the Nexus Layer 1, a 100% EVM-compatible blockchain designed to function as a world supercomputer by concentrating global compute power. This is powered by the Nexus zkVM, a general-purpose virtual machine that enables fast, verifiable compute at a large scale, compatible with languages like Rust, Go, and C++. Nexus also operates the Nexus Verifiable AI Lab, an R&D division focused on the intersection of AI and zero-knowledge proofs, exploring areas like verifiable AI, AI for verification, economic AI agents, and AI-driven economic systems. They encourage participation through their Testnet, where users can contribute their device's idle compute power to earn rewards and help build the network. Nexus targets developers, researchers, validators, and collaborators looking to build autonomous applications and agentic intelligence on their platform.
Skills
About the Role
You will own and evolve the technical architecture across Rust services, Go infrastructure, and Next.js/TypeScript surfaces on Google Cloud. You will write production code in high-leverage parts of the stack, implement shared libraries and complex integrations, and deliver load-bearing changes. You will align system boundaries and interfaces across multiple pods, lead design reviews, and unblock teams on hard technical decisions. You will raise engineering standards by improving code review, testing, observability, on-call, and incident response practices. You will mentor engineers, help calibrate seniority, and translate ambiguous product goals into clear technical plans and execution sequences. You will write crisp design docs, RFCs, and post-mortems to communicate complex systems.
