About the Role

We're growing our Global Security team and are looking for Security Operations Engineers (Mid/Senior) who enjoy building security capabilities - not simply operating them.

This is not a traditional SOC role.

Instead of spending your day triaging alerts, you'll engineer the systems that make Security Operations smarter, faster and more scalable.

You'll work across Detection Engineering, Security Automation, Threat Hunting and Incident Response, building detection logic, automating repetitive workflows and partnering closely with Product Engineering to improve security telemetry across the CloudBees platform.

Whether you're already operating at Senior level or you're a strong Security Operations Engineer ready for the next step, we're interested in engineers who think in automation, code and continuous improvement.

What You'll Do:

Detection Engineering

• Design, build and continuously improve detection rules across cloud, endpoint, SaaS and application environments. 
• Own the full detection lifecycle from hypothesis through deployment and continuous tuning. 
• Create high-fidelity detections using operational threat intelligence, incident learnings and purple team findings. 
• Measure and improve detection coverage using the MITRE ATT&CK framework. 
• Continuously reduce false positives while improving visibility into emerging attacker techniques.

SOAR & Automation Engineering

• Design and maintain SOAR playbooks that automate alert triage, enrichment, containment and response. 
• Identify repetitive analyst workflows and automate them using APIs, scripting and orchestration platforms. 
• Build integrations across SIEM, EDR, CNAPP, vulnerability management and ticketing systems. 
• Help introduce AI-assisted workflows that improve investigation quality and analyst productivity.

Security Operations & Incident Response

• Monitor and investigate security events across corporate and production environments. 
• Participate in weekend on-call support for Security Operations. 
• Lead or support incident response activities including investigation, containment, recovery and lessons learned. 
• Perform proactive threat hunting using telemetry across multiple security platforms. 
• Improve operational playbooks and incident response processes.

Product & Engineering Collaboration

• Partner with Product and Platform Engineering teams to improve security telemetry and logging. 
• Help define security observability requirements for new services. 
• Collaborate with developers to improve security visibility across the CloudBees platform. 
• Translate operational findings into practical engineering improvements.

Vulnerability & Threat Intelligence

• Contribute to vulnerability assessment and management processes, prioritising findings based on threat context and exploitability
• Consume and operationalise threat intelligence feeds, translating indicators and TTPs into detection logic and hunting hypotheses
• Participate in red team/purple team exercises, using findings to validate and improve the detection stack

What You'll Bring:

Required

• 3+ years of experience in Security Operations, Detection Engineering or Security Engineering. 
• Hands-on experience with enterprise SIEM platforms such as Splunk, Microsoft Sentinel, Elastic, Chronicle or QRadar. 
• Experience building and tuning detection rules. 
• Experience developing SOAR playbooks or security automation. 
• Strong scripting skills using Python, PowerShell or similar languages. 
• Experience working within cloud environments (AWS preferred; Azure or GCP experience also valued). 
• Solid understanding of the MITRE ATT&CK framework. 
• Experience supporting security incident response. 
• Comfortable working with Git, APIs and engineering workflows. 
• Excellent communication skills with both Security and Engineering teams.

Preferred

• Experience with Detection Engineering methodologies. 
• Experience with AI-assisted detection or security automation. 
• Familiarity with Sigma, Atomic Red Team or detection testing frameworks. 
• Experience with Infrastructure as Code (Terraform, CloudFormation, ARM). 
• Kubernetes or container security experience. 
• Experience working within SaaS, DevOps or software delivery organisations. 
• Relevant certifications including GCIH, GCIA, GCDA, GCED or AWS Security Specialty.

What Success Looks Like:

Within your first year you'll help CloudBees:

• Increase detection coverage across enterprise and production environments. 
• Improve automation throughout Security Operations. 
• Reduce manual investigation effort. 
• Improve incident response efficiency. 
• Build scalable engineering solutions that enable Security Operations to grow without increasing operational overhead.

What You'll Get:

• Highly competitive benefits and vacation package. 
• Ability to work for one of the fastest growing companies with some of the most talented people in the industry. 
• Team outings.
• Fun, Hardworking, and Casual Environment.
• Endless Growth Opportunities.
