Overview

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.

Key Responsibilities

Proof of Value Ownership

• 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.

Customer Onboarding & Adoption

• 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.

Trusted Security Advisor

• 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.

Required Qualifications

Experience

• 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.

Technical Knowledge

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, GitHub/GitLab, and CI/CD pipelines.
• Understanding of where security integrates across the SDLC/PDLC and the friction points that slow teams down.

AI & Emerging Trends:

• 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.

Skills & Attributes

• 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.

Preferred Qualifications

• 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.
