Software Engineer - Stellar

About The Company

Rain is the global stablecoin payments platform for enterprises, neobanks, platforms, developers, and AI agents. Our technology allows partners to move, store, and use stablecoins instantly and compliantly through global payment cards, rewards, on/offramps, wallets, and cross-border rails. As both a Visa and Mastercard Principal Member, Rain issues cards that work at more than 175 million merchant locations in over 220 countries and territories. Built natively for stablecoins and trusted by more than 100 organizations worldwide, Rain delivers secure, scalable infrastructure that makes money move freely and instantly around the world.

You will have the opportunity to deliver massive impact at a hypergrowth company backed by some of the top investors in fintech, crypto, and SaaS. In January 2026, we closed a $250M Series C led by ICONIQ, valuing Rain at $1.95B, with Sapphire Ventures, Dragonfly, Bessemer Venture Partners, Galaxy Ventures, FirstMark, Lightspeed, Norwest, and Endeavor Catalyst also participating. If you're curious, bold, and excited to help shape a borderless financial future, we'd love to talk.

Our Ethos

We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.

About The Role

You'll design, build, and maintain Soroban smart contracts on Stellar and the backend services that integrate with them, while contributing to shared infrastructure across EVM, Solana, and Stellar. Our platform powers crypto-backed card products — processing high transaction volumes, continuously ingesting on-chain data, and navigating the unique complexity of each chain, with scalability and reliability engineered in from day one.

What you'll do

• Own and evolve Soroban smart contracts end-to-end — from development through deployment and maintenance
• Build robust, scalable backend services that interact with Stellar, EVM, and Solana networks
• Scale our on-chain infrastructure to support millions of users globally — powering transactions, data ingestion, and real-time processing
• Play a central role in shaping the technical and product roadmap
• Drive architectural decisions in a fast-moving, rapidly evolving product
• Ship new capabilities quickly and iteratively to our customers

What we're looking for

• Deep expertise in the Stellar ecosystem, including Soroban's programming model, tooling, and best practices
• Strong proficiency in Rust
• Solid understanding of smart contract security patterns and common vulnerability classes
• Experience with Node.js and backend systems
• 2–10+ years of engineering experience; compensation will be calibrated accordingly

Nice to have, but not mandatory

• Fintech experience — neobank or card issuing background gets extra brownie points
• Familiarity with Stellar classic operations

Benefits

• Unlimited time off — we require Rainmakers to take 10 days minimum for themselves.
• Flexible working — work from home, come into an office, or both.
• Easy to access benefits — we cover 95% of your health, dental, and vision plan costs and 90% for your dependents.
• Retirement goals — we offer a 401(k) with a 4% company match.
• Equity plan — every Rainmaker gets an equity option plan.
• Health and Wellness — Rainmakers receive a monthly stipend for eligible health and wellness spending.
