Lead Product GRC Subject Matter Expert

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it.

Vanta for Government (V4G) is how we bring that mission to the public sector. As federal compliance undergoes its biggest shift in a decade — FedRAMP 20x, machine-readable authorization, OSCAL — we're building the platform that turns federal frameworks into automated, continuously monitored product experiences. The GRC Subject Matter Experts on this team are the people who make that possible.

As Vanta's Lead GRC Subject Matter Expert for V4G, you'll own federal compliance content used by every customer pursuing or maintaining federal authorization on our platform. This is an interpretation-and-authoring role, not a compliance program administration role: your job is to interpret underlying control requirements, identify where FedRAMP modifies or constrains the NIST framework, and translate those interpretations into precise, technically testable guidance that engineering can build and customers can act on. The content you write ships as product — a five-person startup and a Fortune 100 CSP both receive it — so calibrating depth, precision, and universality is the core craft.

You'll join Vanta's Security organization, which directly influences product development, facilitates the creation of automated GRC solutions for customers, and provides expert advisory services across the company.

What you’ll do as a V4G GRC SME at Vanta

- Build and own federal compliance frameworks — Lead the creation, enhancement, and lifecycle management of controls, evidence requirements, and implementation guidance for FedRAMP (Low/Moderate/High), NIST SP 800-53, NIST SP 800-171, CMMC, DFARS, and StateRAMP. Author clear control rationales, acceptance criteria, and customer-facing guidance shipped as out-of-the-box product content.

- Interpret controls at the mechanics level — Work fluently with 800-53A assessment procedures and 800-53B baselines; resolve organization-defined parameters and FedRAMP's constraints on them; decompose controls into distinct technical obligations; correctly resolve inherited, shared, and customer-owned responsibilities within a customer responsibility matrix; and anchor evidence expectations in authoritative artifacts (PPSM, STIG and CIS hardening standards and their scan outputs across operating systems, databases, network devices, and endpoints).

- Author automated tests & continuous monitoring — Translate controls and infrastructure context (AWS GovCloud, Azure Government, GCP, SaaS, endpoints, CI/CD) into spec-level automated tests and detectors. Define test logic, data sources, edge cases, and — critically — failure conditions: how unapproved items, exceptions, missing data, and unevaluated resources affect a result. Pair with Engineering to implement and maintain detectors with versioned framework mappings.

- Lead V4G's machine-readable future — Shape how Vanta's federal content is architected for OSCAL and FedRAMP 20x: machine-readable SSPs, config-as-compliance, and continuous authorization workflows.

- Design crosswalks and mappings — Maintain bidirectional crosswalks across federal frameworks (800-53 ↔ 800-171 ↔ CMMC ↔ StateRAMP) with canonical control IDs, mapping confidence, and traceability to source authority.

- Act as a product advisor across discovery & design — Partner with the V4G PM and Design on feature discovery, review UI/UX for control, evidence, and authorization workflows, and author PRDs and acceptance criteria grounded in agency, auditor, and 3PAO needs.

- Enable AI-assisted compliance — Partner with Engineering/ML to design LLM-powered guidance and automation for federal workflows. Translate SME knowledge into machine-readable sp
