PRINCIPAL, TECHNOLOGY ENGINEERING

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.

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.

We believe in an open and flat structure. We are hiring a Head of Engineering to own the craft, quality, and technical direction of a roughly 30-person engineering organization. It is a role about making a small, senior team produce output that looks like a much larger one — by raising the engineering bar, tightening the systems that move real money, and being genuinely in the code and the architecture rather than adjacent to it.

You will lead through a mix of direct reports and a small group of engineering managers and tech leads, partnering closely with Product, Risk, and Compliance. If your ideal week includes a hard design debate, a code review that changes someone's mind, and a coaching conversation that raises a manager's ceiling, keep reading.

Set and own Rain’s engineering quality bar across system design, code review, testing, observability, documentation, and technical decision-making, ensuring correctness is treated as critical for systems that move customer funds.

Provide hands‑on technical leadership by staying active in the codebase, reviewing critical PRs and designs, prototyping high-risk components, debugging production issues, and making key architectural and build‑vs‑buy decisions.

Own the technical architecture and strategy across card issuing, wallets, ledger, money movement, onchain settlement, and integrations with card networks and banking partners.

Drive reliability, scalability, and operational excellence by establishing SLOs, improving incident response, capacity planning for 10x growth, and designing resilient systems with graceful degradation, idempotency, and replay capabilities.

Build security, compliance, and correctness into the platform by design , partnering closely with Risk, Compliance, and Security to meet PCI, SOC 2, fraud‑control, regulatory, and blockchain infrastructure requirements.

Increase engineering velocity without sacrificing quality through improvements to CI/CD, developer tooling, local environments, technical debt management, and architecture that enables teams to ship safely and independently.

Build and develop a high-performing engineering organization by coaching engineering managers and technical leads, maintaining a high hiring and performance bar, establishing clear team ownership, and partnering effectively across Product, Design, Risk, Compliance, and GTM.

10+ years building production software, including 4+ years leading engineers — ideally as a Head of Engineering, Director, or Senior EM at a company where the systems handled real consequences.

Deep experience with distributed backend systems at scale: data modeling, consistency and idempotency, queues and event‑driven design, and the operational reality of running all of it.

A track record of raising an engineering bar. You can point to specific practices you introduced and the measurable change in quality, velocity, or reliability that followed.

Experience in payments, fintech, banking infrastructure, or another domain where money, ledgers, or regulatory obligations made correctness non‑negotiable.

Strong hiring and coaching instincts, with managers or senior engineers you have developed who would work for you again.

You can make a complex technical tradeoff legible to a CEO, a compliance officer, and a partner's engineering team in the same week.

You would rather ship something correct this quarter than design something perfect for next year.

Hands‑on experience with card issuing, processing, or the Visa and Mastercard network stack.
