Squads Labs is seeking a Senior Engineer to help design and implement a financial APIs platform (Grid) that abstracts complex infrastructure into developer-friendly interfaces. Our REST APIs enable global USD accounts, borderless payments, yield integration, asset trading, and card programs without traditional banking dependencies.

About Squads

Founded in 2021, we started with the release of Squads Protocol, the autonomous finance layer built on Solana. Secured by Solana’s permissionless ledger, Squads Protocol enables programmable payments, 24/7 USD liquidity, competitive yields, and security enforced by deterministic code, not corporate promises. We build on Squads Protocol to bring this stack to every developer, business, and individual. Squads Labs is proud to have its products be the first selected for the initial Stripe stablecoin card launch!
