The Role

We are looking for a technical lead to join our fast-growing Threat Detection and Response (TDR) team and help us forge a next-generation cloud-native managed security service. This role would suit someone currently in a senior security operations or DevOps role that is looking to take the next step in their career and become an expert in cloud security.

Our philosophy is that solid defense requires intimate knowledge of offensive tactics. Our managed security service leverages our penetration testing and red team expertise to ensure our TDR team is across current cyber-attack techniques. This, combined with our cloud-native tooling and deep understanding of AWS services, allows us to deliver best-in-class protection for AWS customer environments.

The successful candidate will work closely with our experienced offensive security and incident response teams to understand the latest TTPs used in real-world breaches. That knowledge will be used to continually improve our next-generation threat detection service and protect our customers from cyber-attacks. Our customers include start-ups, scale-ups, enterprises, and state/federal government agencies, giving this role exposure to a range of technologies and industry sectors.

Your Responsibilities

Our in-house SIEM platform, built on Amazon Security Lake, ingests telemetry from AWS services, endpoint security products, and third-party SaaS vendors. You will be working with our team to continuously improve the detection and investigation capabilities of the platform. You will use findings from our offensive team engagements and MITRE ATT&CK® Matrices to detect the latest threat IOCs and TTPs used by highly skilled adversaries.

You will be responding to alerts generated by our SIEM platform and investigating complex attack chains to ensure breaches are rapidly discovered and contained. Using penetration testing techniques, you will also validate any security exposures detected by our Attack Surface Management (ASM) platform and review the security of new customer assets identified by the platform discovery engine.

Your Typical Day

This is not a typical SOC role where you wait for SIEM alerts to come through, you will be constantly applying your current skillset across different areas and learning new skills every day. A typical day will include enhancing the capabilities of our TDR service, using exploit POCs to validate real cyber threats, and giving security advice to customers in shared slack channels.

Your daily activities will include the following:

• Investigating and responding to potential cyber threats:
• Ownership through to resolution of alerts generated by our SIEM and ASM platforms.
• Liaising with customers to provide updates on alert investigation status.
• Escalating to our offensive security team for validation of complex exposures.
• Closing alerts with investigation outcomes once appropriate action has been taken.
• Review of new assets discovered by our ASM platform and assessing exposure risk.
• Developing high-signal threat detection rules:
• Tuning existing rules to reduce false positive rates.
• Developing new rules to search and alert on threat activity.
• Engaging our offensive security team for rule testing.
• Building a best-in-class cloud TDR solution:
• Updating event ingestion pipelines to enrich data for threat detection rules.
• Monitoring CloudWatch metrics and modifying AWS service configurations as required.
• Reviewing OpenSearch metrics and modifying index configurations as required.
• Developing and maintaining runbooks that improve our threat detection processes.
• Automating routine tasks such as filtering low-priority alerts and sending notifications.

You will also be using your client-facing and engineering skills to work collaboratively with the broader team on projects and periodic reporting. These activities will include:

• Assistance with onboarding new clients to our TDR and ASM platforms.
• Integration of new log sources for existing TDR clients.
• Generation of reports for our managed service clients.
• Presentation of report content to our managed service clients.
