About KAST
KAST is redefining what it means to bank with stablecoins - think Revolut, rebuilt from scratch on Web3. Backed by top-tier VCs, weâve grown from 0 to 1 million users in under a year. Weâre building the next-gen global bank based entirely on stablecoins.
Design is at the heart of everything we do - itâs how we simplify the complex, make money feel easy, and turn crypto skeptics into brand ambassadors.
The Role
Weâre hiring a Tech Lead to own our DeFi and onchain product stack end-to-end. Youâll lead the architecture and development of systems that power our asset management, lending/borrowing, and earn products.
This role is highly hands-on. Youâll design and build backend services, blockchain integrations, and transaction infrastructure while ensuring secure interaction with smart contracts, wallets, and custody systems.
Youâll also help grow the engineering team as we scale â setting technical direction, mentoring engineers, and establishing strong engineering practices.
â
What Youâll Be Doing
- Own the DeFi architecture across backend services, blockchain integrations, and supporting systems.
- Build and integrate DeFi products including lending, borrowing, yield, and liquidity strategies.
- Design secure blockchain interactions, including wallet infrastructure, signing flows, and custody integrations (MPC, multisig, hardware wallets).
- Develop backend systems for transaction management, protocol integrations, and onchain/offchain coordination.
- Lead engineering execution â define architecture, review code, and ensure systems remain reliable, scalable, and secure.
- Hire and mentor engineers as the team grows, establishing strong technical standards.
- Collaborate closely with product and design to deliver high-quality user-facing financial products.
What You'll Bring
- 8+ years of software engineering experience, with experience leading technical projects or teams.
- Strong backend engineering experience in one or more of the following:
Go, Python, or Node.js. - Experience building production systems that integrate with blockchain networks.
- Familiarity with Solana and/or EVM-compatible chains.
- Strong understanding of DeFi systems, including lending/borrowing protocols, swaps, liquidity aggregation, and yield strategies.
- Knowledge of DeFi risk mechanics such as collateral management, liquidations, staking, and yield generation.
- Experience designing APIs, distributed services, and database-backed systems.
- Experience building or operating cloud-based systems (AWS or similar).
- Strong communication skills and ability to drive engineering execution in a fast-moving environment.
â
Nice to have:
- Experience with smart contract development (Solidity, Rust, or similar).
- Experience integrating with custodial and non-custodial wallet solutions.
- Exposure to cross-chain infrastructure or multi-chain architectures.
- Experience with frontend technologies such as React or Next.js.
- Experience scaling engineering teams in a high-growth startup environment.
- Familiarity with AI-assisted development tools (Copilot, Cursor, agentic workflows).

Interview Process
What does a React developer in web3 do?
A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain
These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network
Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain
As a React developer in web3, some of your responsibilities might include:
- Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
- Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
- Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
- Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
