Job Overview

The Advanced Security Engineer is a technically deep, hands-on practitioner who forms the operational backbone of the enterprise security function. Operating within a layered defense-in-depth program, this engineer owns the design, deployment, implementation and optimization of AI-enabled security technologies at all layers. With the goal of enabling automated orchestration of security operations into day-to-day detection and response capabilities, hardening rigor, and rapid response. This role works closely with the Senior Manager of Enterprise Security and cross-functional engineering teams to reduce the organization's attack surface, enable threat landscape adaptability, and improve detection and response times across Relativity's technical ecosystem.

Job Description and Requirements

• As applicable, design, deploy and optimize security controls that span perimeter, network, host, application, identity and data layers, ensuring and maintaining effectiveness of controls at each layer.
• Collaborate cross-functionally to ensure controls are aligned to industry recognized frameworks.
• Validate that telemetry from each layer feeds the central analytics platforms and supports 360-degree visibility and appropriate attack surface coverage.
• Continuously assess effectiveness of enterprise security controls as the ecosystem expands and the threat landscape evolves, supplement or extend coverage accordingly.
• Proactively partner with IT, Engineering and other stakeholders to embed security controls natively.
• Periodically provide recommendations on technical design of security controls aligned to vulnerabilities, risks, issues and/or events.
• Support purple-team exercises and control-efficacy testing to verify depth and resilience under attack conditions.
• Ensure redundant, complementary security capabilities to prevent bypasses and ensure failure redundancy through all security layers.

• Deploy, integrate, optimize and manage EDR/XDR platforms and periodically define custom detections and automated response actions across security tooling.
• Establish and enforce endpoint and image hardening baselines, configuration standards, and application control baselines.
• Integrate endpoint telemetry into the central analytics platform (or SIEM) to support security context and cross-domain correlation; ensure SIEM coverage is adequate and effective.
• Collaborate cross-functionally to ensure security events, exposures, vulnerabilities and alerts are remediated within appropriate SLA's.
• Investigate endpoint-based alerts and incidents through to root cause: perform triage, forensic artifact collection (memory, disk, logs), timeline reconstruction, and containment/eradication actions.

• Collaborate cross-functionally to support purple team exercises and analyze security telemetry to surface anomalous and malicious behavior to the relevant stakeholders.
• Develop, execute and document structured hunts mapped to MITRE ATT&CK and ATLAS techniques and current threat intelligence.
• Perform exposure analysis on identified vulnerabilities, zero-day, alert telemetry, threat intelligence feeds and notifications from partners and customers and conclude on exploitability risk and/or exposure.
• Maintain awareness of the evolving threat landscape, adversary TTP's, and emerging vulnerabilities and their relevance to Relativity's technical ecosystem and organizational trajectory.
• Standardize and document hunt methodology, hypotheses, and outcomes and collaborate with security stakeholders to mature threat hunting program over time.
• Convert successful hunts, exposure analysis, purple team findings and alerts into durable, automated detections and containment logic and improved coverage.

• Build and maintain SOAR workflows that automate enrichment, triage, containment, and routine response actions.
• Measure and continuously improve the impact of automation on time-based detection, containment and response to reduce threat actor dwell time.
• Identify, evaluate and operationalize AI/ML capabilities for semantic anomaly detection, behavioral analytics, alert triage, and prioritization.

• Implement data classification, discovery, and data security posture management across cloud and on-premises stores.
• Deploy and tune data loss prevention controls across endpoints, network, email, cloud and SaaS surfaces.
• Investigate data key risk indicators associated with data access, exfiltration, and integrating data telemetry into central analytics (SIEM).

• Bachelor's in Computer Science, Information Security, or equivalent experience.
• 5+ years of hands-on experience in enterprise security engineering, with a focus on network and/or endpoint security domains (or) Master's Degree in Cybersecurity or relevant field.
• Hands-on experience with common security tools such as EDR, XDR, SIEM, CNAPP, CSPM, CWP, etc. and intermediate knowledge of applicable security technologies at all layers of the OSI model.
• Threat hunting, digital forensics, and/or detection engineering experience and writing automation scripts and rules for security enforcement and/or observability.
• Basic knowledge of industry standard common security benchmarks and frameworks (e.g., MITRE, NIST, etc.)
• Proficiency in at least one scripting/automation language (Python, Bash, or PowerShell) applied to modern containerized services, CLI based commands, and/or security specific use cases.
• Ability to communicate technical findings clearly to both engineering peers and non-technical stakeholders.

• Familiarity with AI-enabled SecOps (e.g., detection: UEBA, ML-based alert prioritization, or AI-assisted threat hunting workflows)
• Basic knowledge of common cloud environments such as AWS, Azure or GCP.
• Working knowledge of software development lifecycle, software engineering practices or infrastructure as code environments: contributing endpoint or network security controls to CI/CD pipelines.
• Experience supporting compliance and audit requirements (SOC 2, ISO 27001, HIPAA) from a technical control perspective.
• Relevant certifications such as SEC+, CISSP, CISA, GCIH, GCFA, GCIA, GPEN, OSCP, CySA+, or equivalent.
