About The Position

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.

Requirements

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.
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.
Extensive familiarity with engineering planning and collaboration tools like Jira, Linear, GitHub/GitLab, and CI/CD pipelines.
Understanding of where security integrates across the SDLC/PDLC and the friction points that slow teams down.
Awareness of AI-assisted software development trends, including the security implications of AI-generated code.
Familiarity with Model Context Protocol (MCP) or similar integration standards for AI tooling is a differentiator.
Understanding of the evolving AI code co-pilot landscape and its impact on security architecture.
Executive-level communication: ability to present security strategy to CISOs and translate complex technical concepts for diverse audiences.
Consultative problem-solving: you diagnose root causes, not just symptoms, and propose solutions that account for organizational constraints.
Cross-functional collaboration: comfortable working across product, engineering, sales, and customer success in a fast-moving startup environment.
Self-directed and proactive: you anticipate customer needs and surface issues before they escalate.
Comfort with ambiguity: this is a senior role in a Series A company—you’ll help define the playbook, not just run it.

Nice To Haves

Industry certifications: CISSP, ISSAP, CSSLP, or equivalent.
Prior experience at a cybersecurity vendor or in a field engineering role at a security-focused startup.
Background in Application Security Posture Management (ASPM), SAST/DAST tooling, or security orchestration platforms.
Experience with enterprise customers in Financial Services, Healthcare, or other regulated industries.
Familiarity with SOC 2 Type II, FedRAMP, or similar compliance frameworks from a vendor perspective.

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.
