Platform Engineer (Stateful)

At Mindbox we connect top IT talents with technology projects for leading enterprises across Europe. 

We are on a mission to build the UK’s leading Banking-as-a-Service platform, underpinned by innovative cloud-native technology. As a Stateful Platform Engineer, you will design and operate shared Kafka and database platform capabilities that enable developers to deliver software reliably, securely, and at scale.

If you have a passion for Kubernetes, distributed systems, and automation-driven engineering, this is an exciting opportunity to make a real impact on modern banking technology.

Sounds like your kind of challenge?

• Deliver changes to Kafka, PostgreSQL, YugaByteDB, and other stateful platform components in a controlled and highly automated way.
• Build self-service platform features using Kubernetes-native interfaces, automation pipelines, and reusable tooling to streamline developer experience.
• Reduce operational toil by simplifying provisioning processes, eliminating ticket-driven workflows, and defining platform golden paths.
• Improve resilience, security, scalability, and operational safety across all stateful workloads.
• Investigate incidents and system performance issues, turning findings into actionable improvements.
• Implement and maintain observability standards, alerting systems, SLOs, dashboards, and runbooks for critical infrastructure services.
• Develop platform software such as operators, controllers, and backend services to manage and automate platform operations at scale.
• Collaborate with product and engineering teams to drive safe adoption of shared messaging and data services.

Note: Detailed project information will be shared during the recruitment process. 

• Hands-on experience with Kubernetes and modern platform engineering concepts.
• Practical operational or development experience with Kafka, PostgreSQL, YugaByteDB, or similar database/distributed systems.
• Strong knowledge of reliability engineering, observability, change management, and incident response.
• Track record of building automation or self-service tools that improve developer productivity.
• Proficiency in writing clean, maintainable, well-tested code (Go or similar languages).
• Strong communication and collaboration skills, with a focus on developer experience and supported adoption.

Nice to have:

• Experience building Kubernetes operators/controllers, ideally using Go.
• Familiarity with AWS managed database services (e.g., RDS, Aurora) or equivalent solutions.
