Platform Engineer

About the project:

We’re looking for a Platform Engineer to join our team to manage and deliver Kafka, databases and other stateful workloads to engineers. You would be a part of our client's team, which is improving their internal platform.

Our client need a qualified person to run the new initiative which enables businesses to embed financial services products such as payments, deposits, point-of-sale credit and merchant cash advances directly into their customer journeys without the hassle of becoming a bank. So there is more like a start up environment rather than corporate one.

Teams will do most of their work remotely from home, coming together, in the office in Warsaw, twice a month to connect & collaborate with colleagues, what they highly value.

Responsibilities

• Build and operate shared platform capabilities for stateful systems such as Kafka, PostgreSQL, and YugaByteDB

• Deliver platform changes in a controlled, well-tested, and safe manner

• Develop Kubernetes-native, self-service solutions using automation and reusable tooling

• Improve developer experience by simplifying provisioning and reducing manual, ticket-driven workflows

• Design and implement solutions that enhance platform resilience, scalability, security, and operational stability

• Develop and maintain platform software, including operators, controllers, and supporting services managing infrastructure at scale

• Define and improve observability practices, including monitoring, alerting, SLOs, dashboards, and runbooks

• Collaborate with engineering and product teams on platform adoption, technical design, and best practices

Requirements

• Hands-on experience with Kubernetes and cloud-native platform engineering concepts

• Practical experience operating or developing systems based on Kafka, PostgreSQL, YugaByteDB, or other stateful distributed technologies

• Solid understanding of reliability engineering, observability, incident response, and safe production change practices

• Experience building automation or self-service tooling that improves developer experience and reduces operational workload

• Strong software engineering skills, with a focus on writing clean, maintainable, and well-tested code (Java/Go)

• Good judgement, strong collaboration skills, and proven ability to work effectively with internal platform users

• Ability to balance deep technical expertise with pragmatic, value-driven delivery

• Excellent English skills (B2+)

Nice to have: 

• Experience building Kubernetes operators or controllers (preferably in Go)

• Familiarity with AWS managed data services such as RDS, Aurora, or similar database tooling
