Cybersecurity Solutions Specialist (Federal Sales)

-Serve as the primary security subject matter expert across federal and commercial pre-sales cycles, owning the security narrative from first conversation through contract award

Lead security discussions with senior stakeholders — CISOs, Program Security Officers, IT leaders, and technical leads — translating complex platform architecture into clear, credible security posture statements

Respond to security sections of RFPs, RFIs, and security questionnaires with accuracy and conviction; support ATO readiness discussions for federal customers and security review processes for commercial customers

Proactively identify and surface security gaps early in the sales cycle — before they become deal blockers — and develop mitigation strategies in partnership with engineering

Build and maintain secure reference architectures for deployments across classified federal environments and enterprise commercial environments

Conduct detailed security gap analysis against customer requirements, drawing on frameworks including NIST 800-53, NIST 800-171, CMMC, RMF/ATO, ISO 27001, and SOC 2 as appropriate to the customer context

Develop security-focused solution concepts and deployment patterns tailored to GovCloud (AWS GovCloud, Azure Government, Google Public Sector) and commercial cloud environments

Define and document how Istari's platform integrates within customer security architectures, including identity and access management, data protection, network segmentation, and audit/logging requirements

Partner with Istari's engineering and product teams to translate customer security requirements — federal and commercial — into concrete roadmap items

Serve as the voice of the customer on security, ensuring product decisions reflect the realities of classified environments, enterprise compliance mandates, and evolving regulatory landscapes

Maintain current awareness of emerging threats, regulatory changes (e.g., CMMC 2.0, Executive Orders on cybersecurity, SEC cyber disclosure rules), and industry trends, advising both customers and internal teams accordingly

Contribute to white papers, technical briefs, and conference presentations that establish Istari as a trusted voice in digital engineering security — across both government and commercial sectors

Develop and maintain sales-enablement materials — security one-pagers, architecture diagrams, compliance matrices — that scale your expertise across the broader team

Build lasting relationships with senior security decision-makers across customer accounts, positioning Istari as a long-term strategic partner

Active TS clearance with SCI eligibility

5+ years of experience in cybersecurity, systems engineering, or a related technical discipline, with meaningful exposure to both federal and/or commercial security environments

Solid working knowledge of NIST 800-53, NIST 800-171, and RMF/ATO processes, combined with familiarity with commercial frameworks such as ISO 27001, SOC 2, or CSF

Experience with cloud security in AWS, Azure, or GCP environments — including GovCloud compliance postures (FedRAMP, IL4/IL5) and commercial security configurations

Demonstrated ability to communicate security architecture to both technical engineers and non-technical executives; strong written and verbal communication skills

Prior experience supporting or leading security aspects of pre-sales, proposal responses, or customer advisory engagements

Experience working within or alongside DoD, Intelligence Community, or Special Access Program (SAP) environments

Familiarity with CMMC 2.0 requirements and their practical implications for defense contractors and software vendors

Exposure to enterprise commercial security requirements, including vendor security assessments, third-party risk management, and enterprise compliance reviews (SOC 2, ISO 27001, FedRAMP)

Familiarity with digital engineering, MBSE, or model-based systems engineering environments — understanding how engineering data flows and what it means to secure a digital thread

Relevant certifications: CISSP, CISM, CISA, CCSP, or equivalent

Hands-on familiarity with DevSecOps practices, including STIG implementation, vulnerability scanning (ACAS/Nessus), and POA&M management

Team Player -- Must possess and demonstrate excellent communication, expectations setting, and trust building skills with internal and external stakeholders

You can walk into a room with a customer's security team — whether a DoD ISSM or a Fortune 500 CISO — and say, "Yes, we meet your requirements — and here's exactly how," and back it up with architectural detail

You understand that every customer's security journey is different: some live in RMF, others in SOC 2 audits, and you adapt your approach accordingly

You are energized by the intersection of emerging technology and security requirements, not intimidated by it

You think in systems: you can see how a security gap in one part of a deployment creates risk in another, and you communicate that clearly

You are a builder: you do not wait for materials to exist — you create the reference architectures, compliance matrices, and security narratives that help Istari win

Shape the future of digital engineering across the DoD and national security ecosystem.

Lead the technical motion at the intersection of AI, engineering infrastructure, and multi-domain collaboration.

Work directly engineering leadership and mission stakeholders on high-impact deployments.

Influence the product roadmap through real mission needs and demo feedback.

Join a high-trust, mission-driven team building transformative technology.
