Job description

The Senior Information Security Administrator is responsible for strengthening the security of enterprise applications, cloud services, APIs, and development practices. This role partners closely with software engineering, DevOps, architecture, infrastructure, and business teams to identify and remediate application security risks, perform secure code reviews, guide secure design decisions, and embed security controls into the software development lifecycle. The ideal candidate combines hands‑on application security experience, a strong development background, cloud security knowledge, and practical security operations expertise to reduce risk across the enterprise.

Key Responsibilities

• Lead or support application security assessments for internally developed, third‑party, SaaS, cloud‑hosted, web, mobile, and API‑based applications.
• Perform secure code reviews and provide actionable remediation guidance for common application security issues, including authentication, authorization, input validation, secrets exposure, insecure dependencies, API abuse, logging gaps, and insecure configuration.
• Partner with development teams to implement secure coding practices throughout the SDLC, including threat modeling, design reviews, peer review standards, and release readiness checks.
• Operate and improve application security tooling such as SAST, DAST, SCA, container scanning, IaC scanning, secrets detection, API security tools, and CI/CD security controls.
• Review application architecture, data flows, cloud deployment patterns, and integration designs to identify security risks before production deployment.
• Translate vulnerability findings into prioritized, risk‑based remediation plans and work with application owners, developers, DevOps, and product teams to drive closure.
• Secure application‑side configurations, including encryption, session management, authentication flows, authorization models, logging, error handling, secure headers, CORS, API gateways, and secrets management.
• Support cloud security control design and validation across platforms such as Azure, AWS, or GCP, including IAM, network segmentation, workload protection, logging, storage security, key management, and policy‑as‑code.
• Advise on DevSecOps practices, including secure CI/CD pipelines, branch protection, dependency governance, artifact signing, container hardening, and environment separation.
• Coordinate with security operations teams on application‑related incidents, suspicious activity, exploit attempts, and remediation validation.
• Support vulnerability management by validating exploitability, reducing false positives, documenting compensating controls, and tracking remediation evidence.
• Develop and maintain application security standards, secure coding guidelines, design patterns, checklists, procedures, and technical documentation.
• Support audit and compliance activities by providing evidence for secure development, change management, access controls, logging, vulnerability remediation, and cloud security controls.
• Mentor developers, security analysts, and IT teams on application security concepts and practical remediation techniques.

Required Qualifications

• Bachelor's degree in information security, Computer Science, Software Engineering, Information Technology, or related field; or equivalent combination of education and experience.
• 5-8+ years of experience in cybersecurity, application security, secure software development, DevSecOps, cloud security, or related technology roles.
• Strong development background with practical experience reading, reviewing, or writing code in languages such as Java, C#, JavaScript/TypeScript, Python, Go, or similar.
• Hands‑on experience performing secure code reviews, application risk assessments, vulnerability validation, and remediation guidance.
• Working knowledge of web applications, API, authentication, authorization, encryption, session management, and secure data handling concepts.
• Experience with application security testing tools such as SAST, DAST, SCA, container scanning, secrets scanning, IaC scanning, or similar platforms.
• Understanding of cloud security fundamentals across Azure, AWS, or GCP, including IAM, logging, workload security, encryption, networking, and secure configuration.
• Familiarity with CI/CD pipelines, repositories, build processes, release controls, and DevSecOps automation.
• Ability to communicate technical findings clearly to developers, engineers, leadership, auditors, and non‑technical stakeholders.
• Strong analytical, troubleshooting, documentation, and prioritization skills.

Preferred Qualifications

• Professional certifications such as CSSLP, CISSP, GWAPT, GWEB, CASE, Security+, CISM, Azure Security Engineer, AWS Security Specialty, Google Professional Cloud Security Engineer, or similar.
• Experience with OWASP risks, secure coding standards, threat modeling, API security, mobile security, cloud‑native security, Kubernetes/container security, or software supply chain security.
