The listing
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. This involves tackling real-world challenges that come with scaling blockchain technology, without compromising on its core principles: decentralization, security and transparency.
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. If you’re energized by solving unprecedented problems, and believe in the role that decentralized systems will play in creating a more equitable digital future, then we want to hear from you.
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. Major players in the space, Robinhood, BlackRock, Ethena Labs, Securitize, Aave, and Apechain are all using the Arbitrum stack.
Arbitrum’s thriving ecosystem wouldn’t exist without our advanced technology stack. Arbitrum, Prysm, ZeroDev. These aren’t just product names. These are tools that are actively reshaping what's possible on Ethereum and advancing its core infrastructure.
To top it all off? We’re backed by $124 million in funding. We’ve demonstrated consistent execution with billions in secured value, thousands of supported projects, and infrastructure processing millions of transactions seamlessly.
The Role:
- 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.
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
