We're hiring for this role in Kraków, Poland or Toronto, Canada. It's a hybrid position, with two days a week in office at the hiring location.
The role
Tripstack is moving its entire data stack from bare-metal VMs to Kubernetes on OpenStack in a new data centre. We are looking for a senior infrastructure engineer who has done stateful migrations before, who can plan, codify, and execute this one safely, and who will own the day-to-day operational health of the data platform once we are there.
This is a hands-on platform and SRE role with a clear, time-bounded mission. You will partner closely with our SRE team on networking, hardware, and Kubernetes fundamentals, and own the data applications — Druid, Spark, Redpanda, Airflow, PostgreSQL, Elasticsearch — end-to-end.
It is not an ML role. We have a separate plan for evolving our MLFlow platform, and the right hire here may grow into more of that work over time, but day-one impact is the migration and the operational health of the platform.
Responsibilities
Lead the data-stack migration
- Plan and execute the migration of Druid, Spark, Redpanda, and our orchestration layer from bare-metal VMs to Kubernetes on OpenStack, with no downtime on stateful workloads.
- Design StatefulSet, PVC, pod-disruption-budget, and rolling-upgrade patterns that are safe for production data systems.
- Codify the migration with Infrastructure as Code — Terraform for OpenStack, Helm or Kustomize for Kubernetes, GitOps via ArgoCD or Flux — so the result is reproducible and supportable by the whole team.
Operate the data platform
- Own the operational health of Druid, Spark, Redpanda, Airflow, PostgreSQL, and Elasticsearch as production systems — segment lifecycle, JVM tuning, ingestion specs, broker/coordinator/overlord internals, partition design, consumer lag, replication tuning.
- Build the KPIs, alerting, dashboards, and runbooks that let us see cluster exhaustion before it becomes an incident, and diagnose it quickly when it does.
- Own the query, report, segment, and tiering optimisations that keep our analytics cost-effective and responsive under load.
Raise the bar on observability and reliability
- Build the Prometheus, Grafana, and distributed-tracing coverage our data systems need. Treat SLOs, error budgets, and post-incident discipline as table stakes.
- Partner with SRE on hardware, networking, and Kubernetes fundamentals — but own the data applications themselves end-to-end.
Requirements
- Strong Kubernetes experience with stateful workloads — StatefulSets, PVCs, pod disruption budgets, and rolling upgrades for data systems. You have done a real stateful migration before and can talk through what went wrong.
- Infrastructure as Code at a senior level — Terraform, Helm or Kustomize, GitOps with ArgoCD or Flux. You have shipped production infrastructure this way, not just experimented with it.
- Observability and RCA discipline — Prometheus, Grafana, distributed tracing, SLOs, error budgets, and the habit of writing the runbook that stops the next incident.
- Production operations experience with at least one of Apache Druid, Apache Kafka or Redpanda, Apache Spark, or Elasticsearch — deep enough to be credible on internals and willing to learn the others.
- 7+ years building and operating production data or platform systems, at least 2 of them on self-hosted or bare-metal infrastructure. You have been on-call for what you built.
- Clear written and verbal English; comfortable working across Kraków, Toronto, Pune, and Stockholm time zones.
Additional Experience That Would Be Considered An Asset
- Deep Apache Druid production operations — segment lifecycle, JVM tuning, ingestion spec authoring, and RCA on broker/coordinator-class failures.
- Apache Spark at scale — DAG execution, shuffle optimisation, memory tuning, Spark-on-Kubernetes.
- OpenStack familiarity — Neutron networking, Cinder/Ceph storage.
- Fluency with agentic coding tools (Claude Code, Gemini, or equivalent) as a real part of your workflow — including the judgement to know when not to trust an AI-generated config for a production data system.
- Python that is production-grade, plus working knowledge of at least one JVM or Go-family language so you can integrate with our services directly.
- Security and secrets management in Kubernetes — Vault, network policies, encryption at rest.
- Change Data Capture patterns, especially PostgreSQL-to-Druid streaming.
- Delta Lake or Apache Iceberg experience and architectural judgement about when to introduce a table format.
- Exposure to travel, flights, or large-scale search and cache systems.
- Interest in growing into ownership of our MLFlow-based ML platform over time. We have a separate plan for that work, but a curious operator is welcome.
