The Optimism Collective leads the blockchain protocol landscape, dedicated to fostering a scalable and sustainable ecosystem. Optimism’s ethos, in sync with Ethereum's vision, tackles pivotal coordination challenges of the digital age. Optimism’s goal is to harmonize private incentives with public good, shaping a resilient future for the Internet. Optimism’s scope spans diverse areas like Gaming, DeFi, NFTs, and Enterprise.

The Proofs team is looking for an experienced software engineer with Rust expertise. We’re developing the infrastructure to enable the secure and permissionless withdrawal of funds from OP Stack chains and the Superchain.

We’re contributing to the Rust Ethereum ecosystem, enabling OP Stack chains to use Reth, and building a rust-based fault proof VM and fault proof program which complement the existing Go-based implementation. We also maintain important Go-based infrastructure, and while we do have Go specialists our values are to put the Optimism mission first and help anywhere that’s needed.

What are the role responsibilities?

• Contribute to important Rust-based Ethereum and OP Stack infrastructure including OP Reth, Kona, and related open-source tools and libraries.
• Evolve our proof system to meet stage 2 requirements using dispute games and/or validity proofs.
• Assist in occasional maintenance of existing Go-based infrastructure as needed.
• Work with other teams and other disciplines within OP Labs, and with our ecosystem of external developers and partners.

What skills do you bring? 

• A deep understanding of the Rust language and ecosystem.
• Blockchain development experience.
• Experience in systems programming, particularly in developing low-level software such as virtual machines, interpreters, or compilers.
• Excellent written and verbal communication skills, with the ability to document technical details clearly and collaborate effectively with team members.
• Strong understanding of cryptographic principles.
• Experience with Zero Knowledge Proofs is a nice-to-have.
