Principal Customer Engineer

C-Serv

Building an AI security services practice as a founding hire in North America with Fortune 500 support. Leading customer success, technical delivery, and team growth in a fast-scaling environment.

Posted 6/30/2026full-timeRemote • 🇺🇸 United StatesLeadWebsite

About the role

Key responsibilities & impact
  • Own the long-term success of enterprise customers from go-live onward: adoption, expansion, renewal, and measurable risk reduction.
  • Lead the delivery of AI security engagements: threat modeling, guardrail design, red-team exercises, control frameworks, and implementation advisory against the platform.
  • Embed alongside customer security and engineering teams, translating their AI risk exposure into outcomes they can see and defend to their board.
  • Turn what you find in delivery into clear, executive-ready narratives that drive decisions, not just technical artifacts.
  • Act as the senior technical voice in enterprise sales cycles: presenting, demonstrating, and defending the proposition to CISOs, security architects, and engineering leaders.
  • Lead discovery that surfaces real risk exposure and shape it into a compelling case for the platform and the services around it.
  • Partner with sales on scoping, solution design, and proposals that win complex, multi-stakeholder deals across the Fortune 500.
  • Help shape the strategy, roadmap, and success of the AI security offering in North America.
  • Define repeatable delivery methods, and feed patterns from the field back into product direction.
  • Lay the foundations of the North America team, and grow into leading it as the function scales.

Requirements

What you’ll need
  • 8+ years in a senior post-sales technical role: customer engineering, solutions architecture, professional services, or security consulting at principal level.
  • Deep, credible knowledge of AI and ML security: adversarial attacks, prompt injection, data poisoning, model inversion, supply-chain risk, and the threat landscape around LLMs and agentic systems.
  • A track record of owning enterprise customer relationships and outcomes, from first deployment through expansion.
  • Comfort across the full sales cycle without losing technical credibility. You can hold a room with a CISO and go deep with a security engineer in the same afternoon.
  • Proven delivery leadership: you have scoped, led, and closed out complex technical engagements with enterprise clients.
  • Entrepreneurial: you are energized by a blank page and comfortable building the road as you walk it.
  • Commercial: you understand deal mechanics, pipeline, and what it takes to win, and you care about the number.
  • Curious: you follow emerging technology because you want to, and you have built with AI systems yourself.
  • Owner's instinct: you take accountability for the long game, not just the launch.
  • Strongly preferred
  • Hands-on experience securing LLM deployments in enterprise environments: RAG architectures, agentic frameworks, fine-tuning, and the security considerations of each.
  • Background in offensive security, red teaming, or adversarial ML research. You understand how these systems are attacked, not only how they are defended.
  • Familiarity with AI governance and compliance frameworks: NIST AI RMF, EU AI Act, ISO 42001, SOC 2.
  • Domain depth in a regulated vertical: financial services, healthcare, defense, or critical infrastructure.
  • A public presence: speaking, writing, research, or a recognized reputation in AI security.
  • Experience standing up a practice, service line, or methodology from the ground up.
