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)
