Senior Technical Consultant - Security GRC

Responsibilities

Client consulting and engagement leadership
Shape problem statements, engagement scope, assumptions, and success criteria with the client sponsor and the account team.
Build workplans, RAID logs, and stakeholder maps; keep delivery on quality even when the client’s evidence or ownership is incomplete.
Facilitate workshops with CISOs, control owners, internal audit, legal, procurement, and business executives. Drive decisions, not status meetings.
Manage resistance, conflicting frameworks, and “we already have a policy” arguments without losing the room or the facts.
Write and present deliverables that survive legal, audit, and executive review: current-state assessments, target operating models, control crosswalks, risk registers, quantified scenarios, roadmaps, and board narratives.
Coach client staff so the program does not collapse when the engagement ends. Consulting value is transfer, not slide volume.
Support pre-sales and scoping when asked: approach, level of effort, risks to delivery, and what “good” looks like for this client.
Framework design, assessment, and rationalization
Assess and design against NIST CSF (1.1 and/or 2.0): profiles, subcategory outcomes, tiers, and CSF as the executive reporting spine.
Assess and tailor NIST SP 800-53 (Rev. 5 preferred): control families, baselines, overlays, common/hybrid/system-specific controls, and assessment procedures.
Assess NIST SP 800-171 implementation for CUI: requirement status, 800-171A-style objectives, scoping of CUI flows, POA&Ms, and contractor obligation implications.
Apply CIS Controls (v8 preferred) as a prioritized operational control set (IG1–IG3), mapped to CSF and 800-53 rather than run as a second bureaucracy.
Interpret and assess the CRI Profile, including diagnostic statements and financial-sector or critical-third-party expectations.
Design or uplift an ISO/IEC 27001 ISMS: scope, SoA, risk assessment and treatment, internal audit liaison, management review inputs, and certification or surveillance readiness.
Build and maintain crosswalks so one control, one owner, and one evidence package can satisfy multiple frameworks
Assurance, evidence, and defensible writing
Design test procedures, challenge evidence quality, and write deficiency and residual-risk narratives that are factual and unambiguous.
Prepare clients for internal audit, ISO certification bodies, customer assessments, and 800-171 / CRI / CSF inquiries.
Produce executive summaries that a non-specialist leader can act on without a decoder.

Required qualifications

Highly proficient written and spoken English at an executive, audit, and client-delivery standard. Grammar, structure, and tone must be consistently professional. You can explain a control failure, a residual-risk position, or a quantified scenario to an engineer, an auditor, and a board member in the register each expects. A writing sample or timed drafting exercise may be required.
Demonstrated senior consulting or equivalent client-advisory experience: scoping ambiguous problems, facilitating senior workshops, managing difficult stakeholders, producing commercial-quality deliverables, defending recommendations under challenge, and transferring methods to the client. Internal GRC operations experience alone is not sufficient unless you can show the same client-facing muscle.

Frameworks (all required, with working depth—not acronym familiarity)

NIST Cybersecurity Framework

NIST SP 800-53

NIST SP 800-171

CIS Controls

CRI Profile

ISO/IEC 27001 (working command of 27002 expected)

Risk (required)
End-to-end risk management (identify, analyze, evaluate, treat, accept, monitor) and risk quantification (scenarios, ranges, expected loss or equivalent, explicit assumptions). “High / medium / low” without a method is not qualification.

Experience and education
Roughly 5+ years in security GRC, risk, audit, or control assurance, including substantial time in consulting, professional services, or a comparably senior client-advisory capacity. Bachelor’s degree in a relevant field or equivalent experience. Seniority is judged by judgment, writing, and client impact—not title inflation.
