Golang Engineer (Mid/Sr/Staff) - FinTech experience required -> 100% Greenfield in Payments - High salary + Stock package - Amsterdam

We're supporting one of Europe’s most exciting fintech scale-ups that is revolutionizing payment infrastructure, headquartered in Amsterdam. Operating cloud-natively on AWS and backed by top-tier investors, the company is on a fast track toward unicorn status, with a Series B funding round scheduled for late 2025, early 2026.

Role

As a Golang Engineer, you’ll join a small, high-performing squad to design, architect, and build greenfield POS payment flows integrated with the company’s core payment platform.

You'll work directly with one of the brightest CTO's we know that is technically very strong and open minded for top-notch solutions. This is greenfield development: no legacy, no red tape – just a clear roadmap, a solid mission, and the right tools.
