Principal DevOps Engineer İş İlanı

We are looking for a Senior DevOps Engineer for one of our international clients operating in the financial technology space. This is a highly ownership-driven role. You will be the sole DevOps Engineer responsible for the infrastructure , so we are looking for someone comfortable working independently, making technical decisions, and owning production systems end-to-end. What you will do: Own the production Kubernetes platform end-to-end: topology, workload isolation, storage guarantees, and upgrade strategy for stateful financial data. Design and operate a dual-footprint model across GCP and Turkish infrastructure with one pipeline and one set of manifests, ensuring environments do not diverge. Build deployment, secrets, and release tooling that enables engineers to ship safely into a regulated environment without creating a gatekeeper. Own observability and on-call processes; define SLOs tied to reconciliation outcomes, build alerting around customer impact, and drive postmortems that improve the system. Enable the platform to produce its own compliance evidence, including audit trails, access logs, data residency proof, and change records. Own the technical side of infrastructure vendor decisions; define requirements, validate provider claims against real workloads, and evaluate proposed solutions. Harden the ingestion path and perimeter, including SFTP intake, tunnel and edge configuration, network segmentation, and key management. Work closely with engineering teams across Istanbul, Frankfurt, and Madrid and help raise the operational standards across the organization. What we are looking for: Strong hands-on experience with Kubernetes and production infrastructure. Experience with cloud environments, ideally GCP. Strong knowledge of CI/CD, containers, networking, secrets management, observability, and infrastructure security. Experience operating business-critical systems where reliability and data integrity matter. The ability to independently own the DevOps function rather than work as part of a large infrastructure team. Strong problem-solving skills and a high level of ownership. Professional working proficiency in English.
