• We are seeking talented Security Remediation Developers to accelerate vulnerability remediation throughput for a large US mortgage lender. Their vulnerability management program is surfacing more fixes than the internal teams can execute, and you will close that gap — researching each finding, implementing the fix at code and configuration level, deploying it, and proving it is closed. This is hands-on engineering work, not advisory work: you will spend your days in the codebase and in AWS.
• Responsibilities:
• • Take prioritized remediation items from the backlog and drive them to deployed, validated completion. • Research assigned vulnerabilities: reproduce where possible, identify root cause, and determine the correct fix rather than the fastest one. • Implement code-level remediation in PHP: refactor vulnerable patterns, fix injection, authentication, deserialization, and exposure defects, and remove hardcoded credentials. • Perform dependency and package upgrades, resolving breaking changes and transitive conflicts. • Perform AWS-side remediation and deployment, including configuration hardening and IAM adjustments. • Execute secret rotation tasks in coordination with the Remediation Lead, updating consumers and migrating credentials to a managed secrets store. • Validate every fix: write or

• Nice to Have:
• • Experience remediating scanner findings at volume (Snyk, Veracode, Dependabot, Checkmarx). • Prior experience burning down a security or technical debt backlog against throughput targets. • Modern PHP frameworks such as Laravel or Symfony, alongside legacy pre-framework PHP. • Infrastructure as Code with Terraform or CloudFormation. •AWS experience deploying and operating PHP applications, covering compute (EC2, ECS, Elastic Beanstalk, or Lambda), IAM, S3, RDS, CloudWatch, and Secrets Manager or Parameter Store.
• •Containerization experience with Docker and ECS or EKS. • Experience integrating with legacy systems such as IBM i / RPG or SOAP services. • Experience in mortgage, lending, or financial services. • Experience working with international clients.
• Join CI&T and be a part of our mission to build secure, resilient software for our global clients. If you have a passion for PHP and AWS engineering and take satisfaction in closing security findings for good, we want to hear from you!
