Senior Application Security Engineer

Required Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Information Security, or a related field — or equivalent hands-on experience.
• Minimum 8 years of experience in roles related to application security, information security, software engineering, SecDevOps.
• A demonstrable track record of independently owning AppSec domains and delivering remediation without close supervision.
• Hands-on experience operating application security scanning tooling (SAST, SCA, secrets, IaC) and integrating it into CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, Azure DevOps, or equivalent).
• Experience securing cloud-native and container/Kubernetes-based applications (AWS, Azure, GCP; Docker, Kubernetes, OpenShift).
• Ability to read and reason about code in one or more modern stacks (Java, JavaScript/TypeScript, Python, Go, or C#) well enough to perform and review secure code, trace data flows, and identify vulnerabilities in source code.
• Scripting and automation in Python, Bash, or PowerShell.
• Design-level understanding of authentication, authorization, and identity — session management, SSO and federation, and OAuth2/OIDC as architectural patterns.
• Working knowledge of applied cryptography — TLS, certificates and PKI, secrets and key management, hashing versus encryption.
• Strong command of HTTP and web API internals — request/response semantics, auth flows (OAuth2/OIDC, JWT, session management), and the authZ failures, injection, and business-logic flaws common to REST and GraphQL APIs.
• Solid understanding of the secure software development lifecycle and where security testing, gates, and controls fit within it.
• Strong working knowledge of OWASP ASVS, OWASP Top 10, OWASP API Security Top 10, MITRE ATT&CK, and CWE.
• Working knowledge of NIST SSDF (SP 800-218), NIST 800-53, NIST 800-171, ISO 27001, SOC 2, and CMMC as they apply to secure software development.
• Hands-on threat modeling experience (STRIDE, PASTA, or equivalent).
• Excellent interpersonal, written, and verbal communication — able to explain and document security risk and remediation credibly to both engineers and non-technical stakeholders.
• Self-starter, team player, and enthusiasm for learning.
• Applicants must be authorized to work in the United States without sponsorship. We are unable to provide sponsorship now or in the future for this position.

Preferred Qualifications

• Direct, hands-on experience with one or more leading application security platforms (e.g., Wiz, Snyk, Apiiro, OX Security, Cycode, Checkmarx, Veracode, or GitHub Advanced Security).
• Hands-on experience securing AI/LLM-enabled and agentic applications; familiarity with OWASP Top 10 for LLM Applications, OWASP Top 10 for Agentic AI, MITRE ATLAS, NIST AI RMF, and Model Context Protocol (MCP) security implications.
• Hands-on penetration testing or offensive security experience across web, API, infrastructure, or AI systems (including prompt injection, jailbreaks, and agent abuse).
• Industry certifications such as CISSP, CSSLP, GWAPT, GWEB, OSCP, OSWE, or AWS/Azure/GCP security certifications.
