What will you contribute?

As an Expert Offensive Security Engineer within the Cyber Defense Team, you'll lead offensive security assessments that strengthen our defense capabilities. Working closely with the larger InfoSec team, detection engineers, and external engineering partners, you'll identify security weaknesses, validate detection mechanisms, and provide actionable recommendations to enhance our security posture. You'll collaborate with various architecture and engineering teams to continuously validate and improve our security controls and detection capabilities, with a strong focus on developing repeatable testing frameworks and metrics-driven security improvements.

Responsibilities & Deliverables :

- Lead offensive security assessments : conduct full-stack security assessments across our entire technology stack.

- Drive detection engineering partnerships : collaborate with detection engineers through purple team exercises, attack simulations, and threat emulation to improve detection coverage.

- Develop custom tools and frameworks : build and maintain security testing tools, frameworks, and automation scripts that enable repeatable testing and quantifiable security improvements.

- Build security metrics : design and implement frameworks to measure security control effectiveness, detection coverage, and improvement over time through consistent testing methodologies.

- Research and innovate : stay current with the latest attack techniques, tools, and methodologies while building out both offensive and defensive security improvements.

- Mentor and collaborate : share knowledge across security teams and foster a culture of continuous security improvement.

Required Experience :

- 5+ years : professional experience in offensive security, with demonstrated experience in red team and purple team exercises, penetration testing, and detection engineering teamwork.

- Development experience : proficiency in Python or other programming language for building security tooling and automation.

- Security assessment expertise : performing full-stack security assessments of web and mobile applications, APIs, on-prem and cloud infrastructure, and backend systems.

- Deep understanding : common attack techniques; exploit development; post-exploitation methodologies; security assessment frameworks (MITRE ATT&CK, PTES); and modern detection stack components (EDR, SIEM, XDR).

- Knowledge : of networking, operating systems, security protocols, security concepts including reverse engineering, cloud security (AWS/Azure), container security, CI/CD pipeline security, API security, and security metrics development.

Certifications :

- Such as OSCP, OSCE, GXPN, or equivalent practical experience.

Interpersonal skills :

- Strong analytical and problem-solving abilities.

- Excellent technical writing for detailed reports; ability to clearly communicate complex technical concepts; self-motivated with a passion for offensive security and detection engineering.
