Staff Engineer

You’ll join a high-growth B2B fintech building a banking platform from scratch, focused on serving complex corporates with a more tailored, high-touch experience than traditional banks. As a Staff Engineer, you’ll work directly with the CTO, owning key parts of a greenfield Java and AWS-based system across payments, FX, and onboarding, helping drive the MVP launch across Europe. It’s a hands-on, high-impact role where you’ll shape architecture, influence technical direction, and play a critical part in getting the product live.

About the job

Staff Engineer (Fintech, Java, AWS) - Dublin, €120-140k (DOE)

We’re working with a seriously interesting fintech that’s about to go live across Europe this summer.

They’re building a B2B banking platform from scratch, think payments, FX, onboarding, lending, all wrapped in a modern, cloud-native stack.

They’ve got their EMI licence in progress, a strong leadership team in place, and now need one key hire:

👉 A high-calibre engineer who can help get them over the line.

💡What’s in it for you

Join at founding stage, not years in

Work directly with the CTO and Principal Engineer

Build a real product going live in months

High ownership, no red tape

Hybrid working (Dublin-based team)

🛠What you’ll be doing

Designing and building core banking infrastructure

Shipping MVP features across payments, FX, transfers

Owning backend architecture (Java + AWS)

Contributing across systems, deployment, and scaling

Working closely with product and leadership

✅What they’re looking for

Strong backend engineer (10+ years ideally)

Java + AWS experience

Background in fintech (payments ideally)

Someone who’s built modern systems, not legacy banking platforms

Comfortable in fast-moving, high-ownership environments

➕Nice to have

Payments / KYC / onboarding experience

Crypto / stablecoin exposure

Startup or early-stage experience

⚠️Quick note

This isn’t a cushy “Staff Engineer in a 200-person team” role.

It’s closer to:

“come in, build, solve problems, and help get a fintech live”

If that excites you, you’ll love it. If not, probably not the right fit.

💰 Salary

€120k – €140k depending on experience
