Systems 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 design and implement high-performance components in Rust, C++, or Go for a DEX engine and protocol runtime. You will build low-latency pipelines for order execution, event propagation, and state updates. You will optimize concurrency, scheduling, memory layout, and I/O for determinism and throughput. You will profile, trace, and benchmark systems to find and resolve performance bottlenecks. You will work with protocol engineers to ensure safety, composability, and consensus compatibility. For senior candidates, you will drive system design decisions and mentor others in performance engineering.
Requirements
- Strong experience with Rust, C++, Go, or other systems programming languages
- Understanding of high-performance or distributed systems such as low-latency engines, runtimes, databases, or OS-level concurrency
- Ability to reason about execution flows, concurrency models, resource lifecycles, and system invariants
- Practical experience profiling CPU, memory, and synchronization overhead
- Comfort working close to runtime constraints where performance, determinism, and resilience are critical
- Excellent Business English communication skills, spoken and written
Responsibilities
