Security Operations Engineer I in London

CloudBees helps organizations build, run, and govern software factories, giving enterprises the confidence to ship software better, faster, and safer. Writing code is no longer the bottleneck. Governing what reaches production and validating its impact is. As enterprises adopt agentic coding, software is created faster than most teams can review, secure, and validate. Without consistent governance, organizations risk shipping code they cannot explain, audit, or trust.

Across every toolchain a customer runs, CloudBees makes each change, human or AI, visible, auditable, and accountable before it reaches production. CloudBees Unify is the product behind this: a governance layer, with context and control-plane capabilities, that enforces consistent policy and evidence across every tool, team, and workflow.

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

Responsibilities:

• 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.
• Design and maintain SOAR playbooks that automate alert triage, enrichment, containment and response.
• Help introduce AI-assisted workflows that improve investigation quality and analyst productivity.
• Monitor and investigate security events across corporate and production environments.
• Participate in weekend on-call support for Security Operations.
• Perform proactive threat hunting using telemetry across multiple security platforms.
• 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.
• 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:

• 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).
• 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.
• 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.
• Build scalable engineering solutions that enable Security Operations to grow without increasing operational overhead.

What You'll Get:

• Highly competitive benefits and vacation package.
• Fun, Hardworking, and Casual Environment.
• Endless Growth Opportunities.

A global community like Jenkins demands a global focus from CloudBees. Organizations with greater diversity - gender, racial, ethnic, and global - are stronger partners to their customers. Whether by creating more innovative products, or better understanding our worldwide customers, or establishing a stronger cross-section of cultural leadership skills, diversity strengthens all aspects of the CloudBees organization.

In the technology industry, diversity creates a competitive advantage. CloudBees customers demand technologies from us that solve their software development, and therefore their business problems, so that they can better serve their own customers. CloudBees attributes much of its success to its worldwide workforce and commitment to global diversity, which opens our proprietary software to innovative ideas from anywhere.
