Remote Backend Jobs

For blockchain technology to revolutionize the digital economy, we require mass adoption, which can only happen with a drastic improvement in UX. Account abstraction is the path to achieving this, and a modular smart account infrastructure will provide the foundations to go beyond just UX improvements (e.g. gas fee and seed phrase abstraction) to a world where powerful onchain products become the norm.

Build at the forefront of account abstraction infrastructure and prepare web3 for its first 1 billion users.

As a Senior Solidity Developer (Solidity + Rust), you’ll lead projects across the Rhinestone Protocol, developer tooling (e.g. ), and the Rhinestone Wallet. You’ll be expected to learn the inner workings of smart accounts, understand the different implementations (e.g. Safe, Biconomy, ZeroDev’s Kernel, etc), and how developers are using them at the application layer. This role will also build supporting infrastructure for the Rhinestone Protocol. This will include building offchain services for the registry operations, and audit marketplace, to support common module types, for example, the integration of relay services and data oracles, and more.

Rhinestone is in its earliest innings and we are innovating at the tip of the spear of account abstraction and wallet infrastructure. This is an opportunity for you to leave a mark on the broader ecosystem and become a true domain expert. You’ll be expected to hold your own with leading teams across the space who we regularly interact with, including Safe, core contributors of ERC-4337, Biconomy, ZeroDev, Circle, and OKX to name a few, to drive forward our development initiatives and ecosystem standards, like .

Responsibilities

• Architecture and design of our protocol with an emphasis on security, performance, and scalability
• Architecture and design of offchain components with an emphasis on security, performance, and scalability
• Develop and execute on best practice frameworks for protocol upgrades and versioning across networks
• Write, deploy, and test smart contracts (either protocol components, or developer tooling or smart account modules) and maintain them in production
• Work closely with the Founders, engineering, and product on the B2B and B2C applications built on top of the Rhinestone infrastructure, including our own wallet
• Stay up to date with the latest Solidity releases, developer tooling, and exploits to ensure we as a team are using best practices

• 6+ years of relevant industry experience
• 2+ years of smart contract development including production deployments of non-trivial protocols and contracts
• Experience building and helping scale complex backend systems with a focus on DevOps
• A sound understanding of CI/CD tools, Docker and container orchestration tools, cloud platforms, and monitoring and logging tools
• High proficiency with Solidity and Rust
• Experience designing, building, testing, deploying, and maintaining high-traffic smart contracts
• Ability to balance shipping quickly with building stable infrastructure
• Experience working with startups
• Contributions to various open source projects, especially in the Ethereum Ecosystem
• A hustler mentality, founding a company or building side projects is a huge plus!
