Senior Backend & Smart Contract Engineer (Rust/Solana)

At Breeze, we’re building the modern infrastructure for earning yield on digital assets — a seamless, non-custodial platform integrated directly into the apps users already love.

Our philosophy is simple: build fast, validate quickly, double down on the things users love, and kill the ones that don’t deserve to live.

You are the right candidate if you care deeply about users, enjoy working close to metal on chain-level systems, and love getting scrappy to build 0→1. At Breeze, the backend is the product — from our risk engine and fund accounting to our Solana programs powering seamless, non-custodial yield.

What you’ll do

• Design and implement Solana smart contracts in Rust for our core yield platform, managing funds, shares, and on-chain routing logic.
  

• Extend and maintain backend systems — indexers, risk engines, and real-time fund analytics — ensuring they are performant and reliable at scale.
  

• Work across the stack to integrate backend logic with our API and SDKs, surfacing clean interfaces to frontend developers and integration partners.
  

• Push our product experiments forward by quickly validating ideas and iterating based on user and partner feedback.
  

• Collaborate with fullstack engineers and product teams to deliver a world-class developer and user experience.
  

Requirements

• Humble and hungry senior-level engineer with 5+ years of experience and exceptional technical skills in your domain.
  

• Deep experience building and shipping Rust-based smart contracts on Solana.
  

• Demonstrated ability to lead medium-to-large scope backend and protocol engineering projects.
  

• Strong understanding of DeFi primitives (staking, lending, AMMs) and experience building crypto products.
  

• Proven track record of delivering in fast-paced, iterative environments and finding product-market fit.
