What You’ll Do:
- Identify security issues, implement and design security controls, tools, and services to improve security systems and processes.
- Collaborate with product and engineering teams to conduct product security assessments during the design phase, including rapid threat modeling and architecture analysis to proactively identify and prioritize security risks, ensuring timely feedback.
- Leverage threat intelligence and an offensive security mindset to anticipate attacker behavior, identify emerging risks, and inform security controls and detection strategies.
- Research novel security threats and vulnerabilities to the business, offering recommendations to the organization and contributing to the evolution of our security team's expertise.
- Protect public-facing applications by analyzing edge traffic and tuning WAF, DDoS, rate-limiting, DNS, and anti-bot controls to detect anomalies while minimizing disruption to legitimate users.
- Develop new security standards and playbooks.
- Lead and execute incident response simulations, including tabletop exercises and red/blue team engagements.
- Provide guidance and mentorship to other security engineers within the team.
- Build and expand capabilities within our agentic security platform to improve threat detection, investigation, and response.
