At Offchain, we aren’t just building products: we’re leading a movement.
As pioneers in blockchain scalability and security, we're at the forefront of transforming how the world interacts with decentralized applications. We're laying the foundation that will define the next generation of digital commerce, governance, and human interaction.
At the center of this vision is our people. Our team is made up of thinkers and doers that embrace new challenges and seek solutions that push existing boundaries.
Why Offchain?
Offchain is setting the pace for the entire Ethereum ecosystem. We built the Arbitrum stack that powers Arbitrum One, the most widely adopted Ethereum scaling solution that exists today.
Arbitrum’s ecosystem is undergoing tremendous growth with hundreds of projects and dApps on Arbitrum One today. Over 100 different teams have used Offchain technology to build their own Arbitrum chains.
Arbitrum’s thriving ecosystem wouldn’t exist without our advanced technology stack. Arbitrum, Prysm, ZeroDev.
To top it all off? We’re backed by $124 million in funding.

The Role
Day-to-day scope for the Senior Backend Engineer, Rust as described in the posting:
- 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.
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.
What you'll work on
- 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
Who you are
Experience and skills the team lists as required:
- 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
Nice to have:
- Experience with WASM
- Familiarity with blockchain infrastructure or smart contract platforms
- Open source contributions within the Rust ecosystem
Perks
What the posting highlights about the offer:
- Remote-first global workforce + NY office
- Professional reimbursement program (facilitates industry conference attendance, certifications, and more)
- Medical, dental & vision coverage (US + some other countries)
- 401k retirement plan + company match (US only)
- Wellness stipend
- Home office set up / ergonomic equipment program
