About Guidehouse

Guidehouse is a leading professional services firm dedicated to helping clients navigate complex challenges. We are committed to creating a diverse and supportive workplace where every employee can thrive. As an Equal Opportunity Employer, we consider qualified applicants regardless of background, including protected veterans and individuals with disabilities. We adhere to all applicable laws regarding criminal history and recruitment practices, ensuring a fair and transparent hiring process.

About the Role

The Senior IT Security Auditor serves as a critical bridge between technical security realities and federal compliance requirements. In this role, you will lead stakeholder engagement and technical delivery for efforts supporting federal agencies with IT controls assessments and program evaluations. This position is ideal for professionals with a background in information security, assurance, or IT audit who are passionate about utilizing their expertise to analyze IT control weaknesses, identify root causes, and develop robust remediation plans for the federal government.

Your day-to-day involves conducting deep-dive assessments using industry-standard guidance and leading best practices. You will interact with a wide range of client stakeholders, from Information System Security Officers (ISSOs) and system administrators to senior leadership, to gather insights and communicate findings. A significant portion of your time will be dedicated to reviewing artifacts such as system security plans, SOPs, audit logs, and vulnerability scans to evaluate the implementation and effectiveness of IT controls against federal requirements like FISMA and NIST SP 800.

Beyond technical analysis, you will play a key role in mentoring junior team members and providing subject matter expertise on IT security matters. You will document your findings in a high-quality, consistent manner that allows for easy review and understanding, ensuring that assessment results are clearly summarized and actionable for clients. This role offers the opportunity to work on ad-hoc requests and lead the planning and execution of IT assessments, both individually and as part of a team.
