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.
At Rhinestone, our technology transforms smart accounts into an open platform for innovation. Today, smart account development is cumbersome and complex. Only the core developers of the account contribute to its features, stifling creativity. Rhinestone enables any developer to build self-contained components, called modules, that extend the functionality of smart accounts. Creating an “app store moment” and introducing a new primitive to supercharge onchain products.
Some of the most compelling products are being built on smart accounts today, including WalletConnect’s Smart Sessions to revolutionize app UX, ZK Email to improve user privacy, Safe7579 to unleash the Safe app marketplace, chain abstraction solutions for instant cross-chain transactions without bridging, and debit card offerings that can be plugged into any smart wallet.
The role
We’re looking for a Senior Full-Stack Engineer to play a foundational role in working across the entire offchain stack of Rhinestone products. These products include developer tooling, offchain services, internal tools, developer-facing platforms, and user-facing applications. This role requires versatility and working across a traditional software stack and integrations with smart contracts on EVM chains.
Rhinestone offers the opportunity to build at the frontier of one of the most important emerging technologies in the Ethereum ecosystem and collaborate with some of the most prominent thought leaders. You’ll be expected to hold your own with leading teams across the space with whom we regularly interact, 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 ERC-7579.
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
Building various components that interact with EVM-based smart contracts, such as:
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 TypeScript/JavaScript 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 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.
Our tech stack
Onchain: Solidity (Foundry)
Offchain backend: Rust, Node, Typescript, and various other JS/TS-based frameworks
Offchain frontend: NextJS, Typescript, and Tailwind
