Platform Engineer

Our client is working on a new initiative that 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 becoming a bank. The work environment resembles a startup rather than a corporate setting. The team works mostly remotely, meeting in the office in Warsaw twice a month for collaboration.

• 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

• 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
