Summary
What you’ll impact
The Senior Offensive Security Engineer is responsible for planning, executing, and leading red team assessments and adversarial simulations across applications, infrastructure, and physical environments. The role leverages scripting in Python, Go, and JavaScript to develop custom tools, and utilizes cloud platforms (AWS, GCP), container orchestration (Kubernetes/Docker), and network analysis techniques to test and harden systems. Key deliverables include threat modeling, penetration testing, automated security testing pipelines, and providing actionable remediation guidance to engineering teams. The engineer collaborates with detection and response teams, mentors junior security staff, and communicates findings to stakeholders at technical and executive levels.
Responsibilities
What you'll do
- Evangelize the Offensive Security Team's Findings and Projects with stakeholders throughout the organization and collaborate with other teams to create solutions that balance security with other priorities.
- Mentor and provide guidance to members of the Offensive Security team.
- Plan and execute red team exercises, including long-term assessments that simulate real-world attack scenarios.
- Perform threat modeling and penetration testing across applications, infrastructure, and corporate environments.
- Develop scripts and tools to support and automate security testing activities.
- Partner with detection and response teams to run adversarial simulations and improve incident readiness.
- Communicate findings clearly and work with engineering teams to remediate identified risks.
- Lead security incidents when pentest or red team findings require them.
- Plan and participate in adversarial simulation exercises with various security teams.
