Staff Engineer

Staff Engineer – Stablecoin (with growth path to Engineering Manager)

Be part of the team building SURO – Europe’s first EUR-backed stablecoin designed for merchants.

At SumUp, we believe small businesses are the heartbeat of Europe’s economy. Our mission has always been to help them thrive. Now we’re taking the next leap: SURO – a stablecoin that will make payments instant, cheaper, and fully compliant.

This is a rare chance to shape the technical foundations of a product at the intersection of fintech, crypto, and regulation — backed by a profitable business serving 4M merchants across 35+ markets.

What’s the opportunity?

We’re looking for a Staff Engineer who thrives on building from scratch, loves mentoring others, and still enjoys rolling up their sleeves in production code. As SURO grows, so will you: this role has a clear path to Engineering Manager once the team reaches scale.

This is a newly created role, designed to bring internal technical leadership to a high-priority project. It’s fast-moving, complex, and full of potential - perfect for someone who thrives in ambiguous, high-impact environments.

What you’ll do

• Build from zero: Lead technical discovery and MVP build-out for SURO, coding daily in Kotlin or Go.
• Architect for trust: Design high-SLA, service-oriented systems that integrate with our ledger, reconciliation, and treasury platforms.
• Grow a team: Start with a small cross-functional squad (2–3 backend engineers + PM), then hire and coach as SURO scales.
• Raise the bar: Embed reliability, security, and observability from day one.
• Bridge domains: Partner with Product, Finance, Legal, and Banking to deliver features that meet regulatory standards.
• Shape the roadmap: Define the engineering path forward and, over time, step into Engineering Manager while staying hands-on.
