Jobs at K4 Tech Solutions

We hire engineers who want to own a product, not a ticket queue. Roles we typically open: backend (Node.js, NestJS), mobile (Swift, Kotlin, Flutter) and full-stack (React, Next.js, TypeScript). What we look for: solid fundamentals over framework trivia, comfort with ambiguity, and the habit of asking why before how. Fintech is regulated and security-critical work — we care that you slow down in the right places. Seniority: mid to senior. We're under twenty people, so there's no layer of leads to catch mistakes. You'll be making calls yourself — with support, but without process as a safety net. All roles are remote. We hire across Europe and work on CET/EET overlap.
