Senior Site Reliability Engineer

Job Description

The Position

Join a global healthcare biopharma technology team in Prague as a Senior Site Reliability Engineer. You will own reliability, scalability, and security for critical platforms and applications that support medicines, vaccines, and animal health products worldwide. This role combines hands-on engineering with strategic leadership: you’ll drive modernization, shape operational best practices, mentor engineers, and collaborate across products and regions to deliver resilient, high-performing systems.

What will you do?

• Lead reliability efforts: define and own SLOs/SLIs, error budgets, availability goals, and improvement plans for services under your scope.
• Design and implement robust, scalable architectures and automation that minimize operational toil and support rapid delivery.
• Build and maintain IaC, CI/CD pipelines, and automated testing to ensure consistent, auditable deployments.
• Drive observability and proactive monitoring: implement metrics, logging, tracing, and alerting that enable data-driven reliability improvements.
• Lead incident response for complex issues, coordinate cross-team resolution, conduct blameless postmortems, and drive preventative actions.
• Establish and codify operational frameworks, runbooks, and standard methodologies to raise operational maturity across teams.
• Coach and mentor SRE and DevOps engineers; foster knowledge sharing and create a pipeline of technical leaders.
• Partner with product engineering, security, platform, and vendor teams to align technology roadmaps, compliance, and lifecycle management (patching, upgrades).
• Perform capacity planning, performance analysis, and troubleshooting for distributed systems and cloud platforms.
• Produce and maintain technical documentation, architecture diagrams, installation qualification/validation artifacts, and compliance evidence when required.

Qualifications, Skills & Experience Required

• BSc in Computer Science, IT, Engineering, or equivalent experience; advanced degree a plus.
• 5+ years of hands-on experience in SRE, Platform, or DevOps engineering with proven ownership of reliability for production systems.
• Deep experience with cloud platforms (AWS preferred; Azure/GCP experience valuable) and cloud-native services.
• Strong skills with IaC (Terraform, CloudFormation, or similar), Git-based workflows, and mature CI/CD pipelines.
• Demonstrated experience defining and operating SLOs, SLIs, SLAs, and error budget processes.
• Proficiency with observability tooling (Prometheus, Grafana, ELK/EFK, OpenTelemetry, distributed tracing).
• Solid programming/scripting skills (Python, Go, Bash, PowerShell, or similar) and experience building automation and tooling.
• Strong knowledge of networking (VPCs, VPNs, load balancing, firewalls) and cloud security best practices and compliance frameworks.
• Experience with platform engineering patterns, multi-tenant platforms, and managing analytics or data platforms is a plus.
• Familiarity with Conversational BI tools, Power Platform, and emerging LLM/Copilot concepts.
• Excellent problem-solving, communication, and stakeholder-management skills; experience working with global, cross-functional teams.
• Relevant certifications (AWS Professional, Kubernetes, etc.) are a plus.

Nice to have

• Prior experience in regulated industries (pharma/healthcare) with understanding of validation and compliance requirements.
• Experience designing or operating cloud-native analytics platforms and multi-tenant services.
• Leadership experience in building and scaling engineering teams or center-of-excellence functions.
