Excentium, Inc. is a Service-Disabled Veteran-Owned Small Business (SDVOSB) that provides Cybersecurity Consulting and Advisory, Assessment, and other IT services to government and commercial organizations. Excentium is an accredited FedRAMP Independent Assessor (IAS), formerly known as a Third-Party Assessment Organization (3PAO).

We have an opportunity for a Senior Cybersecurity Consultant to join our growing Cybersecurity Professional Services (CPS) practice. CPS delivers cybersecurity consulting and advisory, and assessment services to commercial companies that deliver capability to the government, helping clients build, mature, and sustain compliant, risk-informed security programs.

Position Description:

The Senior Cybersecurity Consultant will serve as a trusted advisor to client leadership, providing hands-on guidance across governance, risk, and compliance (GRC); security assessment and authorization; and enterprise security program development. This role will lead client engagements spanning gap assessments, control implementation support, and compliance readiness against frameworks such as NIST SP 800-53, NIST SP 800-171, CMMC, ISO 27001/9001/20000-1, and FedRAMP, as well as support for Authority to Operate (ATO) preparation.

The consultant will develop and present assessment findings, risk register updates, remediation roadmaps, and executive-level briefings to client stakeholders, while helping shape the internal methodologies, templates, and playbooks that scale across the practice. Will serve as a principal point of contact between assigned clients and Excentium for CPS engagements, demonstrating strong written and oral communication skills and sound judgment in balancing security requirements against client operations and business risk.

Excentium is a small but growing company, and this role is expected to grow with it. As the CPS practice expands, this individual will be expected to take on increasing leadership responsibility — mentoring junior consultants, overseeing engagement quality, contributing to business development and proposal efforts, and helping define the practice's service offerings and delivery standards.

Excentium is also developing a cloud-based compliance platform designed to help organizations meet CMMC and FedRAMP 20x requirements. This individual may support the platform's development and cloud deployments — contributing security engineering, cloud architecture, and compliance-automation expertise alongside the development team, and helping validate the platform's own security posture as it matures. This is expected to be a growing part of the role over time and offers the opportunity to help shape a new product line at Excentium.
