Description

• Own day-to-day operations of the Burp Suite Enterprise DAST program: scan scheduling, agent and Linux infrastructure health, scan tuning, and result triage across multiple federal application environments. • Configure and troubleshoot authenticated scans against modern web applications and APIs, including recorded login sequences (via the official Burp recorder Chrome extension), session-handling rules, and macro-based re-authentication. • Diagnose and resolve Burp Enterprise scan failures end to end: consecutive audit-item failures, skipped insertion points, timeouts, session invalidation, and authentication state loss. • Extend Burp Suite Professional with custom extensions (Python/Java/Montoya API) to automate repetitive manual verification, custom authentication flows, and findings validation for the bug bounty program. • Design and implement authenticated scan workflows that survive multi-factor authentication, including SMS one-time passwords, TOTP tokens, hardware dongles, PIV and smart card client-certificate authentication, and SSO federation. • Administer the AppSec team’s own Linux infrastructure in AWS (currently EC2 with containerized Burp Enterprise components) and contribute to the migration to on-premise OpenShift. • Convert legacy Python and shell tooling left behind by previous engineers into Ansible roles and playbooks; manage YAML, Dockerfiles, and Kubernetes manifests as code. • Integrate AppSec tooling into GitHub Actions workflows alongside Dependabot SCA, including the appropriate use of workflow_dispatch versus workflow_call patterns and reusable workflows. • Provide secondary support to the broader AppSec toolset: Veracode SAST, Contrast IAST for interactive scanning and runtime security testing, GitHub Advanced Security workflows, and the HackerOne bug bounty program (validating reported findings with Burp Suite Professional).

🎯 Exigences

• 6+ years of hands-on application security engineering experience. • Demonstrable, current expertise with Burp Suite Enterprise (DAST operations, scan authentication, troubleshooting) and Burp Suite Professional (manual testing, repeater, intruder, session handling). • Strong Linux/Unix administration skills from the command line. • Comfortable answering basic questions like "what command checks disk space" or "how do I check whether a service is running" without hesitation, and equally comfortable with more advanced diagnostics. • Proficiency writing custom Burp extensions and security automation scripts in Python (and ideally Java for the Montoya API). • Working experience with Kubernetes, Docker, and YAML-driven infrastructure. • Experience with AWS CloudFormation (or equivalent IaC) and Ansible. • Experience integrating security scanning into CI/CD pipelines using GitHub Actions, including reusable workflows and Dependabot. • Demonstrated experience designing authenticated DAST scans against applications protected by SSO, MFA, OTP, or PIV/smart card authentication. • Clear understanding of modern authentication and authorization protocols, including OAuth 2.0 flows (authorization-code, client-credentials, refresh tokens), SAML, and OpenID Connect. • U.S. Citizenship and ability to obtain and maintain the required federal Public Trust clearance.

🏖️ Avantages

• Fully remote within the United States. • Standard work day is 8.5 hours with a 30-minute lunch, starting at 8:30 AM EDT with the federal client daily stand-up. • Hours are flexible around the stand-up and any scheduled client meetings. • Small team: you will be one of two to three engineers focused on the AppSec work stream, with direct, daily collaboration with the government technical lead.
