Matrix Systems and Technology is seeking a Systems Security Specialist to perform internal and external penetration testing of networks, web applications, API's, and cloud environments to identify security vulnerabilities and exploit paths, and other related tasks.
Duties/ Responsibilities:
- Conduct internal and external penetration testing of networks, web applications, APIs, and cloud environments to identify security vulnerabilities and exploit paths.
- Perform red team engagements simulating real-world adversary tactics, techniques, and procedures (TTPs) aligned with MITRE ATT&CK.
- Execute vulnerability assessments and validate remediation efforts through retesting and technical verification.
- Develop comprehensive penetration testing reports, including executive summaries, risk ratings, proof-of-concept evidence, and actionable remediation guidance.
- Perform threat modeling and attack surface analysis to identify high-risk exposure areas and privilege escalation pathways.
- Conduct secure configuration reviews of operating systems, network infrastructure, cloud platforms, and identity systems.
- Evaluate application security through dynamic and manual testing techniques, including authentication, session management, input validation, and access control testing.
- Review source code for security weaknesses and secure coding gaps, particularly in C/C++, Python, Java, or similar languages. Develop and maintain custom scripts or tooling to automate testing activities and enhance offensive security capabilities.
- Support incident response activities by recreating attack chains, validating compromise scenarios, and identifying root causes. Assess Zero Trust implementations, micro-segmentation strategies, and identity-based security controls for effectiveness.
- Conduct phishing simulations and social engineering exercises to evaluate user awareness and organizational resilience.
- Provide technical briefings to executive leadership and technical stakeholders regarding risk posture and remediation prioritization.
- Collaborate with engineering, DevOps, and infrastructure teams to remediate identified vulnerabilities and strengthen security architecture.
- Contribute to the development of security policies, testing methodologies, and enterprise security standards.
- Support compliance efforts by mapping testing results to NIST, OWASP, CIS, or other applicable security frameworks.
- Participate in continuous improvement of penetration testing methodologies, tools, and adversary emulation strategies.
- Adhere to all security, change control, and Project Management Office (PMO) policies, processes, and methodologies.
Minimum Qualifications:
- A Minimum eight (8) years of progressive experience in cybersecurity
- A minimum of five (5) years performing penetration testing or red team engagements.

- A minimum of five (5) years developing and delivering formal penetration test reports, including executive summaries and technical remediation guidance.
- A minimum of five (5) years supporting incident response investigations and validation testing.
- A minimum of five (5) years with common penetration testing tools (e.g., Metasploit, Burp Suite, Nmap, Wireshark, Nessus, etc.).
- Strong knowledge of Secure coding practices, Application security testing (SAST/DAST concepts), Network architecture and segmentation and Identity and access management concepts
- A minimum of five (5) years of demonstrated scripting or development ability in at least one language (e.g., Python, C/C++, PowerShell, Bash).
- A minimum of five (5) years of working with NIST Cybersecurity Framework, NIST 800-53 or similar federal control frameworks, MITRE ATT&CK and OWASP Top 10 A minimum of five (5) years of experience mapping findings to security control frameworks.
- At least one recognized offensive security certification (e.g., OSCP, GPEN, GXPN, CEH, or major experience can substitute for certification).
- Demonstrated ability to communicate technical findings to executive and non-technical audiences, and provide actionable remediation recommendations. Demonstrated experience working in government or highly regulated environments.
