Scale security solutions across diverse development teams and applications with varying architectural designs
Analyze code scan outputs from tools like Anchore, WebInspect, and DBProtect, and collaborate with compliance teams to fine-tune and enhance scanning effectiveness
Champion early-stage security integration by building and embedding tools that enforce security checkpoints within CI/CD workflows
Integrate security checks into source control and pipelines to deliver prompt feedback and uncover insecure coding patterns early in the development process
Perform vulnerability scans and penetration tests to detect and address security weaknesses proactively
Apply ethical hacking techniques to uncover and remediate security flaws in both applications and infrastructure
Promote secure development practices in Java, Python, and Angular by offering internal training and hands-on support for secure coding, deployment, and operations
Deploy real-time security monitoring and alerting systems to swiftly identify and respond to potential threats

Bachelor’s degree and over 10 years of hands-on experience in software development using Java, Python, and Angular

Proven expertise in implementing security protocols such as TLS/SSL, IPsec, OAuth, OpenID Connect, SAML, HTTPS, and encryption/key management
Solid grasp of Zero Trust security concepts and practical approaches to implementation
Extensive experience working with AWS services and security tools, including IAM, VPC, CloudTrail, and AWS Security features
Strong background in microservices and container technologies, including Docker and Kubernetes
Track record of integrating security checks and controls into CI/CD pipelines
Knowledgeable in network security, database systems, and hardware-level protections
Exceptional analytical and troubleshooting abilities, with a keen eye for detail
Effective communicator able to explain complex security topics to both technical and non-technical audiences
Experienced in leading projects and mentoring team members to support growth and collaboration
Collaborative mindset with the ability to work closely with developers, ISSOs, security engineers, architects, and other stakeholders involved in solution delivery

Preferred Skills and Experience:

Skilled in using ethical hacking tools and techniques to identify and address security vulnerabilities
Holds relevant certifications such as Certified Ethical Hacker (CEH), Certified Information Systems Security Professional (CISSP), or AWS Certified Security – Specialty
Experienced in contributing to large-scale initiatives involving multiple development and operations teams
Familiar with working on federal government projects, including navigating compliance and regulatory requirements

Salary Range: $75,000 – $155,000 annually This position may be filled at the Entry, Mid, Senior, or SME level based on the selected candidate’s qualifications and experience. Final compensation will be determined based on level alignment, experience, education, and internal equity.
