Summary

The Senior Application Security Engineer is a technical leader responsible for ensuring the security, integrity, and resilience of our cloud-native SaaS applications. This role partners closely with Software Engineering, Product, DevOps, and Security Operations to embed security into every phase of the SDLC. The ideal candidate is hands-on, highly collaborative, and capable of scaling AppSec processes that align with best practices, regulatory requirements, and the needs of a rapidly growing technology organization.

Key Responsibilities

• Embed security into CI/CD pipelines through scalable guardrails, automated security checks, and continuous improvements to developer workflows.

• Drive adoption of secure coding best practices across engineering teams through tooling, guidance, and direct partnership.

• Lead threat modeling exercises for high-risk features and new architecture patterns.

• Own, maintain, and tune AppSec tooling including SAST, DAST, SCA, secrets scanning, container scanning, and dependency management.

• Partner with DevOps to ensure automated testing integrates into build, test, and deploy workflows with high signal-to-noise and minimal developer friction.

• Evaluate emerging technologies and automation opportunities to strengthen AppSec capabilities.

• Lead triage, prioritization, and root-cause analysis for application vulnerabilities discovered through internal testing, bug bounty programs, pentests, and external researchers.

• Ensure timely remediation through strong cross-functional partnership, driving the right balance of risk, velocity, and operational maturity.

• Support security reviews, pen test scoping, and remediation programs tied to GovRAMP, SOC 2, and customer requirements.

• Conduct manual reviews of critical code paths, APIs, backend services, and cloud components to identify security defects that automation may miss.

• Advise on secure design patterns for microservices, cloud-native architectures, authentication/authorization mechanisms, secrets management, and data protection.

• Collaborate with Security Operations during active incidents involving application or product vulnerabilities.

• Perform deep-dive analysis of new vulnerabilities, exploit techniques, frameworks, and supply-chain risks affecting our tech stack.

• Mentor engineering teams on secure design, secure coding, and modern AppSec patterns.

• Lead internal workshops, brown bags, and knowledge-sharing sessions.

• Contribute to internal AppSec documentation, policies, and secure development standards.

Qualifications Required

• 6+ years of application security, secure development, or software engineering experience (or equivalent real-world experience).

• Strong knowledge of modern application architectures: microservices, REST/GQL APIs, React/Node/Java/Kotlin/Go, containerized workloads, Kubernetes.

• Hands-on experience with SAST, DAST, SCA, secrets scanning, container scanning, and CI/CD integration.

• Expertise in OWASP Top 10, ASVS, SANS CWE Top 25, and secure coding principles.

• Ability to perform threat modeling, code review, and architecture analysis.

• Experience partnering with Engineering to drive remediation and long-term maturity improvements.

Preferred

• Experience in SaaS, multi-tenant systems, or high-scale cloud environments (AWS preferred).

• Familiarity with SOC 2, GovRAMP, & TX-RAMP.

• Prior background in DevOps, software engineering, or cloud security.
