Remote Backend Jobs

We’re looking for a Senior Backend Engineer to play a foundational role in developing the offchain infrastructure of Rhinestone’s Protocol. These core components will support the interoperability, security, and viability of an open and permissionless module ecosystem for smart accounts. The position will require experience with blockchain systems and building highly performant backend services.

Responsibilities

• Architect and design our off-chain services using Rust to support feature growth and the rapidly changing requirements of being a startup.
• While your focus will be writing concurrent backend systems, you will also interact with our smart contract systems written in Solidity.
• Work closely with the team to ship new products and develop solutions for challenging technical problems.
• Deliver high-quality code from concept until production.
• Dive into the code of other team members to provide thorough reviews and contributions outside of your own responsibilities.

• 3+ years of relevant experience with blockchain technology (EVM-focused).
• 2+ years of experience writing Rust server code in a production environment (e.g., ethers.rs and/or alloy).
• Experience working with crypto wallets (preferably smart accounts), bridging technologies, blockchain nodes, relayer or intent-based systems, and an understanding of Layer 2 solutions and their integration into the application layer.
• Ability to balance shipping quickly with building a stable infrastructure.
• Self-starter, problem solve from the root cause, able to break down complex problems into simpler components and chart the phases of getting to a stable and scalable solution.
• A hustler mentality; founding a company, working in startups (pre-series A), or building side projects (open source is a plus).
• Able to be a thought leader and highly collaborative to drive toward 10x outcomes.

• Onchain: Solidity (Foundry)
• Offchain backend: Rust, Node, Typescript, and various other JS/TS-based frameworks
• Offchain frontend: NextJS, Typescript, and Tailwind
• Location
• London, UK or Remote (±2 hours of London timezone)
