We’re looking for a senior engineer who’s fluent in Rust and TypeScript and deeply familiar with the Solana ecosystem. You’ll build and maintain platform capabilities and integrations across major Solana protocols—owning on-chain program work, off-chain services, and the TS developer surface (SDKs, tooling).
While deep protocol knowledge is important, you will be building a production web application; strong React/Next.js experience is required.

What you’ll do

- Build and iterate on a production web application in React/Next.js (TypeScript) that integrates directly with our Solana services and SDKs.
- Develop and maintain Squads and its various tooling using @solana/web3.js, SPL libs, and other ecosystem libraries for internal and partner teams.
- Integrate with popular Solana DeFi protocols (DEX/AMM, lending, staking, perpetuals, aggregators).
- Optimize transactions: compute-unit budgets, priority fees, versioned transactions, and batching.
- Collaborate with protocol teams and partners; read specs, review IDLs, and turn ambiguous docs into well-tested integrations.

You might be a fit if you

- Have 5+ years building production systems (systems/backend), with 2+ years in Rust (or deep Go/C++ with Rust ramp) and strong TypeScript.
- Strong experience with React and Next.js (hooks, routing, SSR/ISR) building secure, high-quality web applications.
- Understand Solana runtime basics: accounts model, PDAs, sysvars, rent, CPI, compute units, program logs.
- Know the SPL Token Program (ATAs, mints, decimals, transfers), and have touched major DeFi primitives on Solana.
- Are comfortable with web3 clients (@solana/web3.js, SPL, Anchor), RPC commitment levels, rate limits, and backoff patterns.
- Ship high-quality code with tests, code reviews, and clear docs; you bias to action and own outcomes end-to-end.

Nice to have

- Anchor expertise (IDLs, constraints, tests) and/or native solana_program experience.
- Experience with building products and services on Solana, including: program upgrades/governance, or custom account/state layouts, validator management, etc.
- Integrations with DEXs/AMMs, lending, staking/LSTs, perps, and aggregators; comfort reading other teams’ IDLs/contracts.
- Infra literacy: Docker, AWS, Postgres/Redis, and CI/CD.
- Security mindset: reentrancy/CPI safety, account-constraint design, audit collaboration.
- Experience with modern front-end tooling and components (e.g., Tailwind, Radix UI) and performance/accessibility best practices.
- Familiar with JS/TS Build tools (eslint, webpack, remix, etc).

How we work

Remote-first, async-friendly.
Small, senior team; high ownership and direct impact.
Pragmatic process: plan → build → measure → iterate.

Interview flow

Intro + role deep dive (30–45m)
Technical conversation (Solana runtime, Rust/TS design; React/Next fundamentals)
Practical exercise (code review or small integration task, potentially React/Next)
Team fit & offer

Title: Solana Platform Engineer (Senior)
Location: Remote
Employment: Full-time
Comp: Competitive salary + equity (DOE)

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.
