- We’re looking for a talented engineer to join the Nitro team and help build the core technology powering Arbitrum, the leading Ethereum scaling solution. Nitro is Arbitrum’s node software and the foundation of one of the most widely used scaling solutions in crypto. It enables Ethereum to handle significantly greater throughput at a fraction of the cost while maintaining compatibility with the broader Ethereum ecosystem. The team tackles challenges across execution engines, networking, state management, performance optimisation, and reliability as we continue to push the limits of blockchain scalability. One area of development within Nitro is Stylus, which allows smart contracts written in Rust and C/C++ to be compiled to WebAssembly (WASM) and executed on Arbitrum alongside the EVM. Stylus combines the performance and tooling of modern systems languages with the security and composability of Ethereum, opening the ecosystem to a much broader set of developers. This is a hands-on engineering role focused on solving difficult technical problems at scale. You'll work closely with researchers, protocol engineers, and product teams to design, build, and operate systems used by developers and applications across the Arbitrum ecosystem.
- Building and improving Nitro, the core node software that powers Arbitrum
- Designing and optimising systems responsible for transaction execution, state management, and network performance
- Scaling throughput and improving the performance and efficiency of Arbitrum's core infrastructure
- Solving distributed systems challenges across a large-scale blockchain network
- Enhancing reliability, observability, and security across critical infrastructure
- Developing new capabilities for the Arbitrum stack
- Experienced Rust engineer with a track record of building production systems
- Comfortable working across distributed systems, infrastructure, and performance-critical applications
- Motivated by solving complex technical problems at scale
- Able to take ownership of projects from technical design through implementation and operation
- Pragmatic, collaborative, and capable of making sound engineering trade-offs
- Interested in runtimes, execution environments, WASM, developer tooling, and/or systems programming
- Maintained a security focused mindset, always keeping an eye out for potential threats and vulnerabilities in your code
- Experience with WASM
- Familiarity with blockchain infrastructure or smart contract platforms
