Senior Offensive Security Engineer

Revolutional delivers advanced technology solutions and mission support to federal agencies across civilian, health, and national security environments. We apply modern capabilities, including AI/ML, cloud, cybersecurity, and IT modernization to solve complex challenges, enable faster and more secure operations, and drive measurable mission outcomes.

Title: Senior Offensive Security Engineer Location: Remote Terms: Full-time Salary: $175-185k DOE Clearance: Ability to obtain and maintain public trust as required

This position supports cybersecurity operations and offensive security testing efforts for the Department of Veterans Affairs (VA). The role focuses on conducting time based penetration testing activities that support the Authority to Operate (ATO) process for system owners across enterprise environments.

The environment includes modern web applications, APIs, cloud infrastructure, operating systems, databases, and network devices across both on-premises and cloud hosted systems.

The core challenge: proactively identifying vulnerabilities and security weaknesses before adversaries can exploit them while supporting mission critical healthcare and federal systems and raising the bar of the offensive security team that performs this work.

As a Senior Offensive Security Engineer at Revolutional, you will serve as a technical subject matter expert on an Offensive Security Team; driving the quality, depth, and consistency of penetration testing, web, and Red Team operations support across enterprise systems, applications, cloud infrastructure, and networks.

Beyond executing the most complex assessments yourself, you will help lead the team executing the assessments and aid in providing technical guidance, engagement with government leaders, review findings, mentoring junior and mid-level operators, and elevating the team's tradecraft. You will be expected to be able to conduct assessments and solve hard technical problems end to end, support development of custom tooling and automation (including AI assisted capabilities), and ensure the team efficiently executes and reports offensive engagements.

This role is for a seasoned offensive operator who can think like the adversary, discovery security vulnerabilities that are more than the results of some automated scanning tool, experience using OPSEC minded on target operations as part of a red team campaign and deliver technically accurate reports and articulate the results to leaders that can help improve the security posture of federal systems.

Responsibilities:

• Serves as a senior leader on an offensive security team providing technical expertise across penetration testing, web application testing, and Red Team operations, ensuring a high standard for depth and quality of testing occurs
• Help lead the offensive security team: planning and resourcing engagements, reviewing peer findings, and providing hands on technical mentorship to junior and mid-level penetration testers
• Perform time based penetration tests against web applications, APIs, databases, network devices, operating systems, cloud environments, and infrastructure
• Perform advanced manual web application testing against modern frameworks and APIs, going well beyond OWASP Top 10 to identify complex, business logic, and chained vulnerabilities
• Lead and support advanced Red Team operations, including threat modeling, initial access, command and control (C2), post exploitation, lateral movement, and EDR evasion
• Design and build custom tools, scripts, exploits, and automation to expand and mature the Offensive Security Team's capabilities
• Integrate AI assisted tooling and automation into penetration testing and application security workflows to increase speed, coverage, and consistency
• Review newly published vulnerabilities and develop impact assessments and detection/exploitation guidance for customer environments
• Analyze vulnerabilities and determine associated risk based on exploitability and operational impact
• Author clear, concise, and actionable reports; present findings, metrics, and remediation recommendations to customers, system owners, and executive stakeholders
• Define and evolve testing methodologies, operational procedures, and reporting standards for the team
• Maintain offensive security infrastructure, hardware, and software used for assessments and attack simulations
• Support assessments that may require work outside standard business hour
