You will work with the NE AI and AppSec teams as part of the NE DevSecOps team, building practical skills in tooling, code analysis, and AI-enabled security automation. You will also participate in limited client-facing engagements under mentorship, gaining early exposure to professional security consulting.

• AppSec Tool Management
  • Operate and configure SAST, DAST, SCA, IAST, and RASP tools under mentorship, gaining hands-on experience with each tool category
  • Triage and validate findings from automated security tools, distinguishing true positives from false positives
  • Support tool configuration, tuning, and integration tasks within CI/CD pipelines and SDLC workflows
  • Assist in evaluating and benchmarking emerging AppSec tools, including agentic pentesting platforms
  • Participate in client-facing tool discussions and shadowed engagements under mentorship

• Manual Code Review
  • Review application source code for common vulnerability classes including injection flaws, authentication weaknesses, and insecure data handling
  • Perform manual code review under mentorship across multiple languages, applying OWASP and secure coding standards
  • Document findings with supporting evidence, risk context, and remediation guidance
  • Collaborate with the AppSec team to correlate manual review findings with automated tool output
  • Shadow client code review engagements and contribute to findings documentation under mentorship

Qualifications

• Currently enrolled, or recently graduated with a degree in computer science, software engineering, or a related engineering field; significant hands-on experience with multiple programming languages (required)
• Exposure to one or more programming languages (Python, JavaScript, Java, or similar) and interest in reading and analyzing code
• Demonstrated interest in AI tools and their application to security workflows
• Strong written and verbal communication skills, with the ability to document findings and present results to technical audiences
• Technical aptitude and eagerness to learn hands-on in a fast-paced, practitioner-led environment
• Eastern/Central time zone, preferred
