What the job involves
- We are seeking a detail-oriented and technically skilled Detection Engineer to join our X-OPS team
- In this role, you will be responsible for analyzing advanced security threats - ranging from malware to complex web attacks - and translating threat intelligence into high-fidelity detections across our platform
- Your work will help ensure our analysts and clients receive highly accurate, actionable alerts with minimal noise
- You will leverage data from over 40 third-party and internal sources, partner with our CTU Threat Intelligence team, and use a range of scripting and automation tools to strengthen detection capabilities
- The ideal candidate is a hands-on security practitioner with a deep understanding of endpoint behavior, malware analysis, and detection development who thrives in fast-paced, technical environments
- Develop countermeasures to detect advanced threats based on research and intelligence from the CTU team
- Analyze endpoint behaviors and logs to design detections using multi-source telemetry
- Continuously refine and monitor detection rules to optimize the signal-to-noise ratio for alerts
- Research and implement alert handling for new device ingestions, ensuring high-value signal delivery
- Leverage internal tooling to distinguish native from standard integrations for detection accuracy
- Collaborate on the development of internal tools, automation, and detection infrastructure
- Act as a subject matter expert across departments including Product Management, Marketing, and Labs Research
Our take
Due to the fast-evolving nature of cybercrime, companies can struggle to keep their security up-to-date and resilient. Sophos provides managed cybersecurity services to identify and resolve cyberthreats within all sizes of organisations, combining cutting edge cybersecurity tech with expert support teams.
Leveraging AI and machine learning, Sophos' system automates the detection and blocking of over 99% of threats, meaning its analysts only have to hunt down and stop the most sophisticated attackers. As well as its Managed Detection and Response (MDR) product - which, serving over 15,000 customers, is the most-used on the market - the company also delivers Incident Response Services for those experiencing an active threat.
Sophos is not a new player in the cybersecurity space, but has demonstrated its dedication to innovation with continued product launches, updates, and acquisitions such as that of BAE spinout SOC.OS that have kept its tech at the front of the market. Alongside many of its peers, the effects of the economic climate have caused Sophos to cut staff as it focusses on achieving “the optimal balance of growth and profitability", but this recent hiccup does not take away from its position as a market leader continuously leading adaption in the space.
