Accenture is a leading global professional services company.

As a member of the SOC Content Team, you will be responsible for contributing to the creation, deployment, and tuning of threat detection content and delivery of proactive threat hunting. You will work in close partnership with client Lead Analysts, threat intelligence teams, and other SOC functions to help ensure that detection strategies are tailored to each client’s threat profile and security objectives.

This role offers a balance of technical hands‑on work, collaboration, and knowledge sharing, with a strong emphasis on continual learning and process improvement.

Design and implement detection logic aligned to specific threat scenarios, using industry frameworks such as MITRE ATT&CK. Maintain detection content throughout its lifecycle – from development and testing to deployment and tuning. Work with client Lead Analysts to ensure content relevance and effectiveness in detecting threats across various environments.

Conduct hypothesis‑driven threat hunts based on client telemetry, threat intelligence, and observed anomalies. Use available data sources and tools to identify suspicious or malicious activity that may bypass existing detections. Document and present findings in a clear and actionable format for both internal teams and clients.

Participate in the review and validation of detection content prior to deployment. Assist in updating runbooks, SOPs, and detection playbooks to reflect changes in tools, threats, or client requirements. Support efforts to maintain consistency, accuracy, and quality in all delivered content.

Actively engage with the wider SOC, threat intelligence, and tooling teams to refine detection strategies. Share insights, findings, and improvements with team members through documentation, workshops, or informal sessions. Support cross‑team initiatives and help drive a culture of continuous improvement and innovation.

At Accenture in addition to a competitive basic salary, you will also have an extensive benefits package which includes 25 days’ vacation per year, private medical insurance and 3 extra days leave per year for charitable work of your choice! Flexibility and mobility are required to deliver this role as there may be requirements to spend time onsite with our clients and partners to enable delivery of the first‑class services we are known for.
