Everything below — scope, salary band, equity — is real and current. Join the pipeline at the bottom and you will hear from us first, before the role is ever posted publicly.
Build the Solana leg of Furlpay's x402 facilitator — verify and settle agent payments at scale on the chain where most x402 volume lives today.
What you will own
- Design and ship Solana programs for x402 settlement, escrow and booking receipts.
- Build the Rust services that verify payment authorizations at high throughput.
- Own cross-chain routing between Solana and Arbitrum (CCTP).
What we need to see
- 3+ years of Rust, with at least one production Solana program shipped.
- You can explain rent, CPI, PDAs and versioned transactions without notes.
- Security-first mindset — you write the attack before you write the fix.
Nice to have
- Anchor and program-audit experience.
- Familiarity with the x402 or AP2 specs.
