Rhinestone is building at the bleeding edge of the crypto wallet tech stack.
We built the first ERC-4337-compliant Modular Smart Account, the precursor to ERC-7579.
This is the dominant technical standard for Smart Accounts, which we lead and use as a foundational layer to permissionless wallet innovation and interop.
Our vision is simple: For blockchain technology to revolutionize the digital economy, we require mass adoption, which can only happen with a drastic improvement in user experience (UX).
Smart Accounts are the bedrock for solving crypto’s UX challenges, from easy ones like gas abstraction and key recovery to more complex ones like Ethereum’s fragmented liquidity.
Rhinestone provides Smart Account infrastructure and tooling, enabling developers to build powerful onchain products with web2-like UX.
Our intent-powered infrastructure allows seamless onchain actions regardless of the chain the user is transacting on.
Our open Smart Account module library gives developers maximum flexibility to build the wallet stack they need for their users.
The role
We’re looking for a Senior Engineer to play a foundational role in developing our offchain tech stack.
This includes developer tooling, offchain services, and our developer-facing platform.
This role requires versatility, working across a traditional software stack and integrating with smart contracts on EVM chains.
Developer tooling: We maintain an open-source SDK that enables any developer to easily build on and extend the capabilities of any ERC-7579-compliant Smart Account.
This includes account deployment, key management integration, module customization, and a default transaction infra powered by intents.
Offchain service: We provide an intent-based transaction infrastructure that utilizes settlement layers like Across Protocol to provide chain abstracted transactions and De Fi actions.
Developer-facing platform: We’re developing a simple dashboard to streamline developer interactions and improve Dev X.
If you are nerd-sniped by complex problems at the intersection of scalability, UX, and trustlessness, we’d love to speak with you!
This is an opportunity for you to leave a mark on the broader ecosystem and become a true domain expert.
Responsibilities
- Developer SDKs that are used in frontend and backend applications.
- Offchain services that interact with smart accounts.
- Frontend applications that are used directly by end users.
- Developer-facing applications, such as developer hubs and dashboards.
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.
- Relevant experience
- 3+ years of relevant experience with blockchain technology (EVM-focused).
- 3+ years of experience writing Type Script/Java Script code for production environments, preferably both frontend and backend
- Experience building developer tooling, crypto wallets (preferably smart accounts), bridging technologies, blockchain nodes, relayer or intent-based systems.
- Experience reading Solidity contracts and translating them into code in other languages.
- Ability to balance shipping quickly with building a stable infrastructure.
- Self-starter, problem-solving 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.
- Our tech stack
- Onchain: Solidity (Foundry)
- Offchain backend: Rust, Node, Typescript, and various other JS/TS-based frameworks
- Offchain frontend: Next JS, Typescript, and Tailwind
- Location
- London, UK
What we offer
- Startup equity
- Opportunity to own complex part of tech stack end-to-end
- Flexible working hours and holidays
- Regular team meetups, offsites, and conferences
- A chance to work with the leading minds in account abstraction and the broader web3 space
Rhinestone employs a meritocratic mindset when hiring.
Regardless of background, gender identity, age, religion, etc., we assess candidates by their ability to contribute, collaborate, and deliver excellent work.
