Our requirements
- Strong hands-on experience in Platform Engineering, Site Reliability Engineering, DevOps, or infrastructure engineering.
- Advanced knowledge of Kubernetes in production, particularly stateful workloads, persistent storage, disruption management, and safe upgrades.
- Production experience with Infrastructure as Code and configuration management using tools such as Terraform, Helm, or Kustomize.
- Practical experience with GitOps and automated delivery, ideally using ArgoCD, Flux, or comparable tooling.
- Experience owning production systems, participating in on-call rotations, and resolving complex incidents.
- Hands-on experience operating Kafka, Redpanda, or another production event-streaming platform.
- Experience administering or supporting at least one additional data technology such as Spark, Airflow, PostgreSQL, Elasticsearch, Hadoop, or Apache Druid.
- Good understanding of data ingestion, streaming, partitioning, replication, consumer lag, capacity, and performance.
- Experience implementing monitoring, alerting, dashboards, and structured root-cause analysis.
- You do not need experience with every technology in the stack. Apache Druid, Spark, Redpanda, and OpenStack can be learned if you bring strong Kubernetes, platform reliability, and data infrastructure fundamentals.
- Strong ownership mindset and the ability to operate independently in a small, high-impact team.
- Confidence contributing to architectural discussions and challenging existing solutions when improvements are possible.
- Openness to learning unfamiliar technologies and using modern AI-assisted development tools.
- Clear written and spoken English for collaboration across Poland, Canada, India, and Sweden.
Your responsibilities
- Own the operational health and ongoing development of a self-hosted data platform running on Kubernetes and OpenStack.
- Operate production systems including Apache Druid, Redpanda, Spark, Airflow, PostgreSQL, and Elasticsearch.
- Participate in platform stabilisation, upgrades, bug fixes, capacity planning, and performance improvements following the infrastructure migration.
- Build reliable operating patterns for stateful Kubernetes workloads, including storage, replication, disruption management, and rolling upgrades.
- Define and monitor the KPIs, alerts, dashboards, SLOs, and error budgets required to maintain platform reliability.
- Build observability coverage using Prometheus, Grafana, logging, and distributed tracing.
- Participate in the on-call rotation, respond to production incidents, and coordinate the resolution of major platform issues.
- Drive root-cause analysis, post-incident reviews, runbooks, and preventive improvements.
- Codify infrastructure and platform configuration using Terraform, Helm or Kustomize, and GitOps practices.
- Improve CI/CD processes to make platform changes safe, repeatable, and easy for the wider team to support.
- Automate recurring operational work and reduce manual intervention across the platform.
- Apply appropriate security, secrets management, backup, and disaster-recovery practices.
- Contribute to architectural discussions and help shape the future technology stack rather than simply maintaining the existing design.
- Partner with globally distributed architects, SREs, data engineers, analysts, and data scientists.
- Translate platform requirements into scalable and supportable technical solutions.
- Use AI-assisted engineering tools pragmatically while maintaining strong quality controls for production infrastructure.
About the project
We are hiring on behalf of our client, an established and profitable international technology company operating within a larger global group. Its mission-critical product platform processes tens of billions of data points and supports hundreds of millions of searches every day.
As a Senior Data Platform Engineer, you will take operational ownership of a self-hosted, open-source data platform following its migration from bare-metal virtual machines to Kubernetes on OpenStack. Your focus will be on stabilising, maintaining, automating, and continuously improving the platform that supports data engineering, analytics, and data science teams.
This is a hands-on role at the intersection of Platform Engineering and Site Reliability Engineering. You will work closely with architects and technical leaders, contribute to architectural decisions, and act as a key point of contact for the platform’s reliability and evolution. This is not a traditional data engineering, analytics, or ticket-based operations role.
Key takeaways:
Stack: Kubernetes, OpenStack, Terraform, Helm/Kustomize, ArgoCD/Flux, Apache Druid, Redpanda/Kafka, Spark, Airflow, PostgreSQL, Elasticsearch, Prometheus, Grafana
