Descrição da oferta de emprego

At CI&T, we help large enterprises transform the potential of AI into real business impact with AI Deployment, AI-native execution, and tech-integrated business solutions.

With 30 years of experience in technological transformation, we accelerate innovation with expertise in Agentic SDLC, Application modernization, Data & AI, Martech and Business strategy.

We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day.

At CI&T, our rapid growth is fueled by the innovative solutions we create for our global clients.

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 extend automated tests, confirm the finding no longer reproduces, and document closure evidence the client's risk program can report on.
• Work embedded with the client's engineering team, following their branching, code review, CI/CD, and definition of done.
• Identify recurring patterns that warrant a systemic fix rather than repeated one-off remediation, and contribute them to the remediation playbook.
• Support the client's engineers in adopting secure coding practices.

Requirements:

• Bachelor's degree in Computer Science, Information Technology, or a related field.
• Professional PHP development experience, including work on legacy or inherited codebases.
• Good English communication skills (reading, writing, and speaking) — daily collaboration with a US-based engineering team.
• Demonstrated secure coding practice, with the OWASP Top 10 as vulnerabilities you have personally remediated.
• Practical AWS experience
• Strong dependency management with Composer, including resolving upgrade conflicts.
• Proficiency with Git, code review discipline, and CI/CD pipelines.
• Experience writing automated tests with PHPUnit or an equivalent framework.

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!
