About The Opportunity
As an Application Security Engineer, you’ll play a critical role in helping our engineering teams design and build secure, resilient applications. You’ll lead hands-on product security assessments, collaborate on secure architecture and threat modeling, and influence engineering practices to raise the bar for software security across our organization.
What you'll get to do
• Lead product security reviews: Conduct full-scope security assessments of our applications and services—including code reviews, threat modeling, and both dynamic and static analysis. You'll work across teams to identify and mitigate risks early in the development lifecycle.
• Influence architecture and design: Serve as a security thought partner for product architects and engineers. You'll guide threat modeling efforts, assess technical risk, and champion security best practices throughout the SDLC.
• Drive strategic initiatives: Own high-impact security projects that shape the future of our product security posture. Past initiatives have included supply chain security automation, advanced SAST/DAST integrations, and secure development training programs.
• Identify and support remediation of vulnerabilities: Leverage available tools (e.g., static/dynamic analysis, scanning platforms, and internal reports) to investigate security issues, assess root causes, and design effective remediation strategies. Partner closely with engineering teams to provide guidance and support throughout the implementation of fixes, ensuring they align with security best practices.
• Enable engineering teams: Act as an embedded security advocate and collaborator, helping development teams move fast—safely. You'll create guidance, tooling, and processes that make it easier to build secure software.
