Hey there!👋
At Fourthline, our mission is to fight financial crime. We help protect the global financial system by verifying millions of identities for banks, neobanks, online brokers, crypto exchanges, or insurers like N26, Trade Republic, flatexDEGIRO, Nationale Nederlanden, Qonto, Shine, Solarisbank, and more.
Having started our journey in January 2018 only, we're incredibly proud to count around 250 employees between our Amsterdam and Barcelona offices with over 50 nationalities.
🚀 The Mission
We’re building something big — a next-generation multi-cloud, multi-account platform built on strong GitOps principles. Our mission is to create a reliable, scalable, and secure infrastructure foundation that accelerates development, drives automation, and empowers both internal and external teams.
As part of the Platform Engineering team, you’ll design, build, and run our Platform-as-a-Service — the backbone that hosts all our microservices. You’ll take ownership across the stack: CI/CD, API-driven automation, Infrastructure as Code, observability, security, scalability, cost optimization, and incident response.
We’re in the exciting phase of building from scratch — designing and delivering a cutting-edge infrastructure while experimenting with new technologies like Crossplane, CDK8S, and our custom-built CLI that automates manifest generation with ArgoCD.
It’s a place where you can make an impact, learn fast, and shape the future of how we do cloud and AI infrastructure. You’ll also collaborate with our AI team to deliver high-performance ML infrastructure that accelerates model delivery to production. And yes — we’re a smart, passionate, and fun bunch of engineers who love what we do. We love experimenting with and using new AI technologies, like LLMs, MCPs, and Cursor. We do weekly knowledge-sharing sessions and internal demos where we showcase our achievements with the security team.
