Security Engineer
Job Type: Fixed-Term Contract (6 months)
Working Arrangement: Hybrid – 2 days in the office per week
Office Location: City of London
Full Job Description
This is an exciting opportunity to play a pivotal role in delivering and advancing security engineering initiatives within a globally recognised law firm. You will join a fast-paced and dynamic environment where you'll contribute to a variety of security projects, helping to strengthen the firm's security capabilities while supporting key business objectives.
This is not a traditional SOC role. Whilst SIEM engineering and integration experience remain essential, the focus is firmly on security engineering, project delivery, platform improvements, and business engagement. We're looking for someone who can successfully balance multiple priorities, adapt quickly to changing requirements, and drive security initiatives forward with minimal supervision.
The Role As a Security Engineer, you will:
* Lead and contribute to a range of security engineering and improvemeant projects across the business.
* Enhance, optimise, and integrate security technologies, with a particular focus on SIEM platforms and associated tooling.
* Identify, onboard, and integrate new log sources across cloud, on-premise, network, endpoint, and identity environments.
* Design, build, and implement security solutions that improve the organisation's detection, monitoring, and response capabilities.
* Develop and refine detection use cases, dashboards, workflows, and automation initiatives.
* Support the design and execution of security-related change and build activities.
* Work closely with technical teams, security stakeholders, and business users to deliver successful outcomes.
* Provide subject matter expertise and technical guidance across security platforms and projects.
* Produce and maintain high-quality technical and operational documentation.
What We're Looking For Essential Experience
* Proven experience working in a Security Engineering role rather than a purely SOC or analyst-focused position.
* Strong hands-on SIEM engineering and integration experience with platforms such as Microsoft Sentinel, Splunk, Exabeam, QRadar, or Elastic.
* Experience delivering security-related projects, change initiatives, and platform enhancements.
* Strong understanding of log ingestion technologies and formats including JSON, Syslog, CEF, and XML.
* Experience building and tuning detections, correlation rules, dashboards, and security workflows.
* Scripting and automation experience using tools such as Python, PowerShell, or similar technologies.
* Ability to manage multiple projects and competing priorities within a fast-paced environment.
* Excellent communication and stakeholder management skills, with the confidence to engage directly with both technical and non-technical audiences.
* Strong business English, both written and verbal.
Highly Desirable
* Previous experience working within a law firm, professional services organisation, or consultancy environment.
* Experience working in client-facing or business-facing security roles.
* Knowledge of MITRE ATT&CK, threat detection, security operations, and security architecture principles.
* Familiarity with SOAR platforms and security automation.
* Relevant certifications such as CISSP, SSCP, Microsoft SC-200/SC-100, or GIAC certifications.
* A Level 4 qualification or higher in a computing-related discipline, or equivalent commercial experience.
Who Will Succeed in This Role?
We're looking for a high-energy, proactive individual who thrives in a fast-moving environment. You'll be comfortable operating autonomously, driving initiatives forward, and adapting to changing business priorities. This role will suit someone who enjoys building relationships across the organisation, can communicate effectively with a wide range of stakeholders, and has a track record of delivering successful security engineering outcomes.
