About Squads

Squads is a financial technology company building products and APIs for the stablecoin economy. We build on open infrastructure, global money and internet capital markets to deliver better financial services to every business, individual and developer.

Our Products

  • Squads Multisig: The premier multisig platform for Solana.

  • Altitude: A global business account to save, earn and move money.

  • Fuse: A personal finance app for stablecoins and tokenized assets.

These three products are powered by our stablecoin infrastructure and developer platform: Grid.

Our investors include Haun Ventures, Multicoin Capital, Electric Capital, Coinbase Ventures, Toly, Mert, and others.

Grid is our stablecoin API for accounts, payments, cards, policies, and yield. It powers our first-party products and provides developers with the tools to launch stablecoin products 10x faster, with infrastructure that scales from MVP to managing billions in deposits.

Grid combines programmable policies with key management, payment orchestration, card issuance, and yield providers in a single integration point to offer a complete solution for building a fintech app.

About the Role

We’re hiring a Senior Backend Engineer to design and build high-performance REST APIs in Rust.

The role can flex between a purely hands-on builder or a backend architect who still codes regularly. EU Friendly timezone preferred.

What you will be doing

  • Design and build high performance REST APIS

  • own key backend services,

  • integrate with external systems,

  • contribute to architectural decisions as we scale.

Qualifications

  • 5+ years backend experience building production-grade APIs

  • Strong experience with Rust, or deep systems background in Go or C++

  • Proven experience designing and maintaining high-throughput services

  • Strong understanding of REST design, data flows, and system boundaries

  • PostgreSQL experience (schema design, performance tuning)

  • Exposure to caching (Redis), Docker, and AWS or similar infra

Nice to Have

  • Architectural design experience across multiple services

  • Async Rust (Axum or similar), Terraform, DataDog

  • Fintech or transaction-heavy product experience

  • Startup or small-team experience

  • Technical mentoring or setting backend engineering standards

  • Unlimited, flexible PTO

  • Flexible work schedule

  • Company laptop and allowance for any necessary home equipment

Our Values

  • Kindness Matters. We show kindness and respect to all users, customers, and team members in every interaction (internal and external). Being kind compounds and strengthens our relationships.

  • Craftsmanship Excellence. We deeply care about the quality of everything we create. Every contribution, regardless of size, must meet our high standards for excellence.

  • Radical Transparency. We communicate openly and honestly with each other. Respectful candor is valued over comfortable silence, as we can't afford to miss insights due to fear of speaking up.

  • Bias for Action. We believe action produces information. At no more than 20% completion of a project we must have a working prototype to test and iterate on.

  • Speed with Purpose. We move with urgency and focus. Slow and expensive usually go together. Good, fast, and cheap outcomes are perfectly achievable through disciplined execution.

  • Professional Integrity. We never speak negatively about competitors, partners, vendors, or others. Such behavior reflects insecurity and provides no value.

  • Creative Problem-Solving. We value innovative thinking that challenges conventions. The best solution aligns with the task at hand, not necessarily with how things have always been done.

  • Team Over Ego. We share both successes and failures collectively. No individual's ego should surpass our commitment to the product and its impact.

  • Results Over Hierarchy. We do not care about titles in this company. No politics, no hierarchy. All we care about is winning together.
