Senior Backend Engineer – Payments

Amsterdam | 90k - 110k | Permanent

Python • FastAPI • React • GCP • Early Engineer

Working with a payments startup that’s already doing what most early-stage companies are still talking about. They’re live in production, routing real transactions, with real merchants, and just landed a €2.1 million seed round.

Recently raised from a top-tier European B2B SaaS investor, on the back of strong commercial traction.

Small team. High bar. No room for passengers.

Why does this one stand out?

• Early… but not chaos, foundations are already in place
• Product is live, solving real problems in a complex payments ecosystem
• Already working with scaling startups and global brands
• You’ll have real influence across architecture, product, and team
• You’re not joining a team… you’re helping build it

This is one of those roles where, in 12–18 months, you either say:

“Glad I got in early”

or

“ damn it, wish I had.”

What you’ll be working on;

• Building and scaling a payments orchestration platform
• Routing transactions in real-time across multiple providers
• Designing systems that need to be reliable, fast, and correct
• Owning features end-to-end (idea → production → iteration)

Stack:

• Python (FastAPI)
• React
• GCP, Terraform, CI/CD

What they’re looking for 🎯

• 5+ years building and shipping real products
• Backend-leaning full-stack
• Strong fundamentals > specific frameworks
• Cloud experience (GCP or AWS)
• Someone who enjoys ownership, ambiguity, and building things properly

The offer 💰

• €85k–€100k + equity
• Hybrid, flexible, grown-up culture
• Real impact from day one on a live product
• Clear path to Staff / Lead as the team scales

If you want early-stage energy without the “we’re still figuring it out” chaos, this is a very good one.

No corporate fluff. No glossy perks.

Just strong people, a real product, and proper upside.

2026 is going to be big for them. If you want in early, now’s the time. 👊
