Senior Field Security Architect

Prime Security is pioneering the future of Product Security with the first Agentic Security Architect. As AI transforms how software gets built, we’re reshaping how it gets secured, shifting security to the design phase, where the biggest impact is made.

Backed by top-tier investors and already trusted by members of the Fortune 500, Prime is defining a new category and setting the standard for how AI will power the next generation of secure software development.

Prime Security is seeking a Senior Field Security Architect to serve as the technical cornerstone of our customer‑facing team. This role is the bridge between our Agentic Security Architect platform and the enterprise security leaders who depend on it.

This is a senior individual contributor role. The ideal candidate combines the strategic mindset of a Security Architect, the technical fluency of a Solutions Engineer, and the relationship instincts of a trusted advisor. You will own the full technical relationship with prospects and customers, from initial Proof of Value through production adoption, ensuring they realize measurable outcomes from design‑stage security coverage.

• Lead end‑to‑end POV execution for prospects, the value of the platform through all stages of the POV period.
• Map customer threat models, security workflows, and architectural patterns to Prime’s platform, translating technical fit into business outcomes.
• Collaborate with Sales to build compelling, evidence‑based business cases that resonate with CISO and senior buyers.

• Own the technical onboarding journey—from integration configuration through first automated design review and beyond.
• Configure the Security Context Engine to reflect each customer’s organizational security posture, approved design patterns, and risk tolerances.

• Serve as the authoritative technical voice for key accounts, providing strategic guidance on integrating design‑stage security into their PDLC.
• Translate customer security architecture challenges into platform requirements, feeding insights to Product and Engineering.
• Advise customers on emerging risks from AI‑generated code and how Prime’s Guard capability provides secure architecture context to AI coding assistants.
• Provide proactive, high‑touch engagement for strategic accounts, ensuring satisfaction, retention, and expansion.
• Act as the senior escalation point for complex technical issues, coordinating across engineering, product, and customer success to drive resolution.
• Contribute to platform strategy by surfacing patterns across customer environments—common integration challenges, recurring security architecture gaps, and opportunities for new use cases.

• 8+ years in a customer‑facing technical role (Sales Engineering, Solutions Architecture, Security Engineering, or similar) with at least 3 years at a senior or principal level.
• Demonstrated experience as a Security Architect or in a security‑focused role within a mid‑to‑large enterprise environment.
• Deep, hands‑on understanding of product security review processes, threat modeling, and secure design principles in enterprise settings.
• Proven track record of leading POVs and onboarding for security or developer tooling platforms with enterprise customers.
• Experience working within or alongside software development and product teams—you understand how features move from design to production.

Security Architecture & Frameworks:

• Comprehensive knowledge of threat modeling methodologies (STRIDE, PASTA, Attack Trees, LINDDUN) and practical experience applying them in design reviews.
• Fluency with security frameworks: OWASP, NIST CSF/SSDF, ISO 27001, MITRE ATT&CK.
• Understanding of secure‑by‑design principles and how they apply across the PDLC—from requirements and architecture through implementation, testing, and deployment.

Development Lifecycle & Tooling:

• Extensive familiarity with engineering planning and collaboration tools like Jira, Linear, Git Hub/Git Lab, and CI/CD pipelines.
• Understanding of where security integrates across the SDLC/PDLC and the…
