• Excellent working knowledge about cloud security in relation to the major CSPs.
• Proficiency in scripting languages (Python, Go, Bash, PowerShell, etc.).
• Deep knowledge of MITRE ATT&CK and adversary-emulation frameworks.
• Understanding of detection architectures (EDR, SIEM, SOAR) and telemetry generation.
• Ability to build secure, observable, fault-tolerant services.
• Experience automating adversary simulation or Purple Team workflows.
• Hands-on with IaC (Terraform/CloudFormation) and containerization (Docker/Kubernetes).
• Familiarity with MITRE ATT&CK, D3FEND, CAPEC, and threat-informed defense methodologies.
• Integration experience with ServiceNow, Jira, or enterprise workflow systems.

Responsibilities

• Help maintain and evolve a secure, scalable adversary-emulation platform for campaign scheduling, agent orchestration, payload execution, and results cataloging.
• Review commercial alternatives for Purple Team exercises using custom runners or commercial tools (e.g., Cymulate, Picus).
• Provision static or ephemeral test environments via Terraform/Kubernetes across cloud and on-prem infrastructure.
• Develop continuous adversarial threat-simulation tests for defensive control validation and resiliency assessment.
• Generate high-fidelity telemetry for EDR, SIEM, and SOAR to measure detection coverage, latency, and control effectiveness.
• Research detection brittleness, design mutation/variant tests, and enhance test cases to strengthen detection logic.
• Manage work intake pipeline and ensure timely closure of ticketed requests within SLA.
• Produce ATT&CK-mapped artifacts, dashboards, and coverage metrics for Detection Engineering and leadership.
• Enforce platform security through RBAC, secrets management, audit logging, and execution safety controls.
• Collaborate with CTI, Threat Hunt, and SOC teams to evolve test cases based on real-world threats and gaps.

Benefits

• Affordable medical plan options, a 401(k) plan (including matching company contributions), and an employee stock purchase plan.
• No-cost programs for all colleagues including wellness screenings, tobacco cessation and weight management programs, confidential counseling and financial coaching.
