Summary:

Client is seeking an Application Security Consultant to join the greater Information Security Team and help advance our enterprise application security program. This role will play a critical part in the design, build, and operation of security capabilities that protect Wyndham s web, mobile, and cloud-native applications. The position requires broad application security experience across secure development practices, code analysis, cloud security, and production protection technologies.

As a member of the Cybersecurity Team, the consultant will execute and mature the application security architecture and framework across development, cloud, and production environments. The position will work directly with business application teams on secure design, code review oversight, release coordination, and production resilience. This role will formally represent the application security team in discussions involving new projects, architectures, and security control design, ensuring cybersecurity requirements are embedded early and consistently. Regular interaction with both technical and business personnel will be required to provide risk-based security analysis and recommendations that balance protection, performance, and delivery timelines.

The consultant will administer and optimize static code scanning solutions such as Checkmarx, ensure vulnerabilities are identified and remediated in alignment with OWASP Top Ten and broader industry risks, and collaborate closely with AWS engineering teams to secure Lambda functions and runtime resources. The role will also partner with change and release management to coordinate production code deployments from both security and reliability perspectives, while maintaining operational oversight of application-layer protection technologies.
