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.
