K4 Tech Solutions careers
K4 Tech Solutions is a remote-first team of under twenty people building fintech products: neobanks, payment platforms, mobile apps and SaaS tools.
What we work on: payment systems and banking integrations, PCI DSS-compliant platforms, neobanking apps for iOS and Android, SaaS products, and LLM-based automation.
Stack: Node.js, NestJS and Express on the backend; React, Next.js and Angular on the frontend; Swift, Kotlin and Flutter on mobile; Python and OpenAI for AI integration.
How we work: weekly demos, clear deadlines, and estimates that come from the engineers who do the work. Async by default — we keep meetings few so nobody's day gets fragmented.
A small team means engineers see the whole product and take part in architecture decisions. We look for people who want to understand the problem domain, not just close tickets.
