Senior Security Engineer (SIEM) - RDT Security Platforms

At Roche you can show up as yourself, embraced for the unique qualities you bring. Our culture encourages personal expression, open dialogue, and genuine connections,  where you are valued, accepted and respected for who you are, allowing you to thrive both personally and professionally. This is how we aim to prevent, stop and cure diseases and ensure everyone has access to healthcare today and for generations to come. Join Roche, where every voice matters.

The Mission: You will be a key member of the SIEM team, contributing to the engineering and strategic evolution of our global Security Log Management and Vulnerability Scanning services. This is an end-to-end ownership role: from defining the roadmap and architectural strategy to hands-on engineering and operational excellence. You will ensure our security infrastructure is not only reliable and scalable but also optimized for the modern era of federated data and AI-driven automation.

Description of the area

• →

  Service Ownership & Strategy: Drive the end-to-end lifecycle of our Security Log Management (Splunk & Cribl) and Security Scanning (Tenable) platforms.

• →

  Service Reliability: Ensure the high availability and performance of our security services globally, acting as an escalation point for complex technical challenges.

• →

  System Interconnectivity: Develop and manage sophisticated API integrations to ensure seamless data flow between the security scanning (Tenable) and logging (Splunk/Cribl) tiers.

• →

  Next-Gen Security Log Architecture: Drive the transition from a traditional "index-all" logging approach to a "data-tiering" mindset. You will focus on cost optimization and performance across all data lifecycle phases: routing, filtering, storing and searching, ensuring security data is accessible and cost-effective.

• →

  Infrastructure as Code (IaC): Orchestrate the evolution of our security infrastructure by managing all configurations via CI/CD pipelines (GitHub, Ansible, and Python), to ensure a fully automated and version-controlled environment.

• →

  AI-Augmented Engineering: Actively integrate AI Agents and MCP (Model Context Protocol) servers into daily operations. You will build agentic AI workflows to automate configuration, troubleshooting, and complex interconnectivity, while simultaneously improving service offerings and user experience.

• →

  Mentorship: Act as a technical catalyst for the team, mentoring colleagues in the art of prompt engineering, agentic AI development, and advanced AI ecosystems.

• →

  Technical Leadership: Serve as a technical lead, defining implementation plans and driving continuous process improvements.

• →

  Stakeholder Engagement: Effectively manage relationships across functional teams, acting as a clear communicator and advisor to ensure alignment on security goals and project delivery.

• Security Service Depth: Deep conceptual understanding of the SIEM/Log Management lifecycle (Collection, Indexing, Storage, Retention and Searching) and Vulnerability Management.

• Networking Fundamentals: Expert understanding of networking (TCP/IP, Load Balancing, Firewalls) as it relates to high-volume security data transport.

• Coding & API Mastery: Strong experience with Python and interacting with complex REST APIs. Proven ability to interconnect disparate technologies via APIs and custom integrations.

• Modern DevOps: Strong experience with Ansible and GitHub for managing infrastructure.

• Advanced AI/Automation: Proven experience or deep project work building Agentic AI workflows. Practical expertise in MCP (Model Context Protocol) or building custom LLM-based tools to automate technical tasks.

• Tooling (Preferred): Experience with Cribl, Splunk, or Tenable is a plus, but the ability to rapidly upscale and automate these via AI is essential.
