The Staff Site Reliability Engineer is responsible for the availability, performance, and operational maturity of our cloud-native platform and the critical data and AI/ML services that run on it. This is a senior individual contributor role: you will set reliability direction across teams, raise the engineering bar through standards and mentorship, and do the hands-on work of making complex distributed systems predictable.

This position reports to the Senior Director, Data and AI Platform and is part of the Chief Information Officer (C I O) Office and will be located onsite in Krakow, Poland.

This is a Danaher Corporate role, hosted by our Cytiva operating company in Kraków.

In this role, you will have the opportunity to :

-
Champion SRE practice at scale. Establish and monitor Service Level Objectives and error budgets for critical services, and use them to drive real decisions about reliability, availability, performance, and cost-efficiency — including when to slow down and when to ship.

-
Own observability end to end. Design, implement, and maintain monitoring, logging, and distributed tracing for cloud-native applications and infrastructure (Kubernetes, microservices), and build the dashboards, alerts, and runbooks that give teams deep insight into system health rather than alert noise.

-
Eliminate toil. Identify repetitive operational work and manual process across the production estate and automate it away, developing the tools, scripts, and pipeline improvements that make operations, deployment, and incident response faster and safer.

-
Lead incident response and learning. Participate across the full incident lifecycle — detection, triage, mitigation, resolution — and lead thorough blameless postmortems that get to root cause and produce preventative measures that stick .

-
Shape systems before they're built. Partner with development teams to influence the design of new services so operability, reliability, and cost-efficiency are engineered in from the start, and proactively surface performance bottlenecks and architectural weaknesses before they reach production.

-
Set technical direction and grow the team. Drive cross-team architecture and reliability decisions, establish standards and documentation, mentor engineers across our operating companies, and help foster a culture of technical rigor, blameless learning, and collaboration.

The essential requirements of the job include:

-
5+ years of hands-on experience in a Site Reliability Engineering, DevOps, or equivalent role focused on production system reliability and operations; CS/Engineering degree or equivalent practical experience.

-
Strong understanding and practical application of SRE principles — SLOs, error budgets, toil reduction, and blameless culture — with proven experience participating in and improving incident management processes for business-critical systems.

-
Expertise designing, implementing, and managing observability platforms for cloud-native environments (e.g., Prometheus, Grafana, Datadog, ELK stack, OpenTelemetry , Splunk), including the dashboards, alerting, and runbooks that make them actionable.

-
Extensive hands-on experience with at least one major cloud platform (A
