Lead Application Security Engineer

This position follows a hybrid work model, with an expectation to be in the office 3 days per week at the St. Petersburg, FL Corporate Office location.

Please note: This role is not eligible for Work Visa sponsorship, either currently or in the future.

Responsibilities:

• Lead application security engineering activities across web applications, APIs, mobile applications, cloud-native services, containers, and supporting platforms.
• Embed security controls throughout the software development lifecycle (SDLC), including requirements, architecture, design, development, build, test, release, and post-production monitoring.
• Design, implement, tune, and govern automated security testing in CI/CD pipelines, including static application security testing (SAST), dynamic application security testing (DAST), interactive application security testing (IAST), software composition analysis (SCA), secrets detection, infrastructure-as-code scanning, container image scanning, API security testing, and mobile application testing.
• Develop reusable automation, integrations, and security-as-code using Python, PowerShell, JavaScript, shell scripting, APIs, webhooks, and pipeline platforms to reduce manual effort and improve control coverage.
• Build automated workflows that normalize, correlate, enrich, deduplicate, prioritize, ticket, route, retest, and close application vulnerability findings across security tools and engineering systems.
• Leverage AI-assisted application vulnerability analysis to summarize evidence, identify code-to-vulnerability relationships, propose test cases, prioritize likely exploit paths, explain findings to developers, and draft remediation guidance.
• Perform manual and tool-assisted application and API security assessments, validate exploitability, eliminate false positives, create proof-of-concept evidence when appropriate, and provide clear, actionable remediation guidance.
• Lead application threat modeling and architecture risk reviews using practical methods such as abuse cases, data-flow analysis, trust-boundary analysis, and attack-path modeling.
• Partner with software engineers, architects, product owners, DevOps/platform teams, cloud teams, and risk stakeholders to translate security requirements into pragmatic engineering solutions.
• Develop and maintain secure coding standards, reusable security patterns, guardrails, reference implementations, and developer enablement materials aligned with OWASP guidance and recognized industry practices.
• Serve as a technical escalation point for complex application vulnerabilities and major cybersecurity incidents; participate in an on-call rotation as required.
• Mentor application security engineers and developers, contribute to technical strategy and roadmaps, and remain current with emerging attack techniques, defensive technologies, and AI-enabled software development risks.

Knowledge, Skills, and Abilities:

• Demonstrated expertise identifying, validating, explaining, and remediating application and API vulnerabilities, including vulnerability classes represented in the OWASP Top 10 and OWASP API Security Top 10.
• Advanced understanding of authentication, authorization, session management, cryptography, input handling, deserialization, server-side request forgery, business-logic abuse, and modern client/server attack surfaces.
• Hands-on experience with SAST, DAST, IAST, SCA, API testing, secrets detection, container scanning, infrastructure-as-code scanning, and penetration-testing tools; ability to tune controls and validate tool output rather than rely solely on scanner severity.
• Strong automation and software engineering capability in Python and at least one of PowerShell, JavaScript/TypeScript, Go, Java, C#, or shell; experience consuming REST/GraphQL APIs, processing structured data, writing tests, and maintaining production-quality code.
• Experience integrating security tools with CI/CD and engineering platforms such as GitHub, GitLab, Azure DevOps, Jenkins, Jira, or comparable technologies.
• Demonstrated experience applying AI-assisted or machine-learning-enabled security tooling to source-code review, vulnerability triage, exploit-path analysis, test generation, remediation support, or finding correlation.
• Experience securing cloud-native applications on Microsoft Azure, Amazon Web Services, and/or Google Cloud Platform, including identity, secrets, workloads, APIs, containers, serverless services, and Kubernetes.
• Ability to communicate technical risk clearly to developers, architects, executives, auditors, and non-technical stakeholders, and to translate findings into prioritized engineering actions.
• Ability to lead through influence, exercise sound judgment under uncertainty, mentor others, and balance security outcomes with client and business needs.

Previous Experience:

• Typically requires 3 or more years of hands-on application security, product security, penetration testing, secure software development, or software security assessment experience.
• Demonstrated experience developing security automation and integrating application security controls into CI/CD workflows.

Certifications:

One or more of the following certifications, or the ability to obtain a relevant certification within one year, is preferred:

• GIAC Web Application Penetration Tester (GWAPT), GIAC Certified Web Application Defender (GWEB), or comparable application security certification.
• Offensive Security Web Expert (OSWE) or comparable advanced assessment certification.
• AWS, Microsoft Azure, Google Cloud, Kubernetes, or DevSecOps certification relevant to the assigned environment.
