We are currently undertaking a massive evolution of our infrastructure: transitioning our core financial logic from a high-volume Postgres monolith into a clean, Go-based distributed architecture. We are looking for a Senior Engineer who thrives on technical complexity and wants to leave a legacy by building our next-generation transactional systems.
Why Join Transfer & Funds?This is a "change the engines while the plane is flying" opportunity. You will work on the most critical systems at Trustly, solving the industry's hardest problems in transactional consistency and scale. If you enjoy deep technical puzzles and want to own the bedrock of a global fintech leader, we want to hear from you.
Apply now and help us architect the future of global payments.
WHAT YOU'LL DO

System Design & Distributed Architecture: You understand the nuances of distributed systems. You know how to build application-level safety nets, handle partial failures, and ensure "exactly-once" processing across service boundaries.
Relational Power-User: You have experience in SQL and relational databases, like PostgreSQL. You understand transaction isolation, locking strategies, and how to refactor schemas under heavy production load.
Migration Experience: You’ve successfully moved logic out of legacy environments into modern architectures. You know how to bridge the old and the new without disrupting live operations.
High-Availability Focus: You design for failure. You value observability and have experience running mission-critical services in AWS/Kubernetes environments.

What We Do
At Trustly, we envision a world in which online payments are fast, simple and secure for everyone — merchants, consumers and banks alike. One hundred years ago, cash was king. People got paid in cash, carried it in their wallets, and bought things with it at the local store. Payment was easy. Oh, how the times have changed. Today, our salaries are deposited straight into our bank accounts and we shop online, from merchants all around the world. So why is it so hard to pay straight from our bank accounts? For consumers, paying online should be as easy as sliding a bill across the counter. And accepting payments and issuing refunds should be the least of merchants’ worries. Credit cards, debit cards, e-wallets, invoices and cash-on-delivery are all middlemen levying fees, debt and interest for the simple task of moving money from one person to another. At Trustly, we work hard to make online payments easy.
Why Work With Us
At Trustly, we work hard to make online payments easy. We’re dynamic, not stuffy. We’ve got the drive and ambition of a startup and the experience and advantage of a scale-up, all wrapped up in one amazing team. The pace is fast, and change is frequent. We prioritize agility to adapt to whatever tomorrow brings.
