WHY SOLIDGATE?

• Impactful work: You're building financial infrastructure that solves a real, felt problem — international companies that can't access EU banking. What you ship directly affects company revenue and the lives of the businesses using it.
• Creative freedom: The Banking product is two years old, the codebase is clean, and there's no legacy holding you back. Experiment, propose architecture decisions, and lead the solutions you believe in.
• Career growth: Middle to Senior in 6–12 months is a realistic path here, with coaching from engineers who have 8–10+ years in fintech. Want to expand into Golang or Kotlin? That door is open too.
• Ownership culture: You own features end to end — from RFC to production. No hand-offs, no waiting for someone else to decide. What you build today shapes how the platform scales tomorrow.
• People worth working with: A small, senior team that writes thoughtful code, does real reviews, and ships things that matter. Smart, experienced teammates who raise the bar and actually have each other's backs.

💌 The Extras: 30+ days off, unlimited sick leave, free office meals, health coverage, and Apple gear to keep you productive. Courses, conferences, sports and wellness benefits — all designed for ideas, focus, and fun.

Tomorrow’s fintech needs your mindset. Come build it with us.

🫂 Know top talent? We’re always on the lookout. Refer someone https://jobs.ashbyhq.com/solidgate/form/external-referral-program for our role, and if they get hired, there’s a bonus waiting for you — simple as that.

You will join the Banking team – a small, focused group building financial infrastructure for digital companies that struggle to access EU banking. Many businesses, especially from Ukraine and CEE, can't open EU business accounts at all, or wait months to do so. Our product removes that blocker: companies get a business account, can send SEPA and SWIFT payments, receive payouts to cards, exchange currencies, and manage everything through one portal.

Your immediate team: a Senior Backend Engineer with 10+ years in fintech and AI, a Senior Backend Engineer with 8+ years including crypto, a Middle Frontend Engineer with 6+ years, and a Junior AQA Engineer. We're growing it now to launch corporate cards — a new product that lets business clients issue and manage cards directly through the platform.
