Your New Company

Your New Role

The Senior Application Security Analyst is responsible for embedding security into the software development lifecycle (SDLC) by partnering closely with application and engineering teams.
This role focuses on identifying, assessing, and reducing application and API security risk through threat modeling, secure design reviews, vulnerability management, and the operationalization of application security controls.
The successful candidate will act as a subject matter expert for application security, providing hands-on guidance to development teams while helping mature secure development practices across the enterprise.

What You Need to Do

What You'll Need to Succeed:

Application & API Security

Perform application and API security assessments, including design reviews, threat modeling, and architecture reviews, in alignment with enterprise application security standards.
Identify security risks across custom-built, SaaS, and third-party applications and work with application owners to define practical remediation plans.
Review authentication, authorization, data handling, and integration patterns to ensure secure-by-design implementations.

Secure SDLC & DevSecOps

Embed security requirements and controls early in the SDLC (“shift left”) by working directly with development and delivery teams.
Support the integration and tuning of Static Application Security Testing (SAST), Software Composition Analysis (SCA), secret scanning, Dynamic Application Security Testing (DAST), and other application security tooling within CI/CD pipelines.
Provide secure coding guidance and recommendations based on OWASP Top 10 and industry best practices.
Develop and maintain clear, reusable documentation and standardized frameworks to enable consistent adoption of application security practices across teams.

Vulnerability & Risk Management

Triage and assess application security findings from automated tools, penetration tests, and manual reviews.
Partner with application teams to prioritize remediation based on risk, exploitability, and business impact.

Advisory & Stakeholder Engagement

Act as a trusted security advisor to application owners, architects, and developers.
Contribute to the development and maintenance of application security standards, patterns, and guidance documentation.
Support third-party assessments and security reviews for externally developed or hosted applications.

Continuous Improvement

Identify opportunities to improve application security processes, tooling, and governance.
Stay current with emerging application security threats, vulnerabilities, and defensive techniques.

Required Qualifications:

Bachelor’s degree in Computer Science, Information Security, or a related field, or equivalent practical experience.
5+ years of progressive experience in application security, secure software development, or product security.
Strong understanding of web and API technologies (HTTP/S, REST, JSON, OAuth, OpenID Connect, SAML).
Hands-on experience with application security testing tools (SAST, SCA, DAST, secret scanning).
Solid knowledge of OWASP Top 10, threat modeling methodologies, and secure coding principles.
Strong analytical, problem-solving, and communication skills, with the ability to explain security risks to both technical and non-technical audiences.
Exceptional interpersonal skills and proven to flourish working in a fast-paced
Ability to work effectively in a cross-disciplinary team, across multiple projects and multiple locations.
Experience securing cloud-native applications in AWS and/or Azure environments.
Familiarity with API gateways, WAFs, and runtime protection controls.
Experience working in agile or DevOps delivery environments.
Relevant security certifications (e.g., CSSLP, GWAPT, GWEB, CISSP, OSCP).
Strong knowledge of one or more modern programming languages (e.g. Python, Java, C++, JavaScript).

Additional Requirements

Must be eligible to obtain a Reliability Security Clearance.
Proficiency in English is required for this position due to the frequent communications that must be conducted in English with various stakeholders. This requirement is justified by the nature of the responsibilities and operational needs.

What You'll Get in Return:

Opportunity to work in a fast-paced environment focused on secure software development and application security.
Exposure to enterprise-scale application, API, and DevSecOps security initiatives.
Opportunity to partner closely with engineering, architecture, and product teams to advance secure development practices.
Professional growth through engagement with modern security technologies, frameworks, and cloud-native environments.
