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?
Hybrid: 2x/msc from the office in Warsaw
What you’ll be doing
- 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.
