Summary
What you’ll impact
The Senior Offensive Security Engineer plans and executes red‑team exercises, threat modeling, and penetration testing across applications, infrastructure, and enterprise environments. They develop automation scripts in Python, Go, and JavaScript, leveraging network protocol knowledge, cloud platforms (AWS, GCP), and Kubernetes/Docker to uncover and remediate security weaknesses. In addition, they mentor team members, communicate findings to stakeholders, and lead incident response when critical vulnerabilities are discovered.
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.
