Principal Applied AI Researcher (Prisma AIRS)

Job Summary

Your Career

As a Principal Applied AI Researcher on the Prisma AIRS Runtime Security team, you will serve as a technical visionary and strategic leader shaping the future of AI security.

You will partner with executive leadership, product management, UX designers, ML engineers, and cross-functional engineering teams to conceptualize, architect, and deliver enterprise-grade, cutting-edge AI detection and protection solutions for the Prisma AIRS Runtime Security product. You will be at the vanguard of innovation for an industry-defining product in the rapidly evolving space of AI Runtime Security.

Your responsibilities will transcend standard model development to lead continuous accuracy, latency, and efficiency optimizations, enabling high-throughput integrations across AI threat detection infrastructure, real-time guardrail pipelines, and partner engineering teams.

You will drive technical excellence across the organization, set architectural and research standards, and act as a force multiplier by mentoring other researchers and engineers on the team.

Your Impact

• Lead cross-functional collaboration with Product Management, ML, and Quality Engineering teams to deliver new, enterprise-grade AI security-as-a-service offerings in a timely, predictable fashion.
• Tackle complex, ambiguous technical challenges across system boundaries, translating high-level product and security vision into resilient, production-ready AI detection models and backend architectures.
• Design and select optimal AI architectures-from lightweight ML baselines to complex Transformers-to solve high-impact runtime security challenges.
• Train, fine-tune, and align domain-specific foundation models using modern techniques (PEFT, LoRA, DPO) and distributed training frameworks.
• Build scalable pipelines to filter, clean, and generate high-quality synthetic datasets for model training workflows.
• Develop automated benchmarks, LLM-as-a-judge evaluations, and real-time pipelines to monitor model accuracy, and drift in production.
• Develop models using techniques to minimize compute costs and meet strict, low-latency performance targets.
• Architect scalable model-serving infrastructure using high-throughput engines (vLLM, Triton) integrated into enterprise backend services.
• Mentor senior and junior engineers and researchers, fostering a culture of technical excellence, algorithmic rigor, and continuous learning within the team.

Your Experience

• 8 years of related experience with a Bachelor's degree; or 6 years and a Master's degree; or a PhD with 3 years experience; or equivalent experience.
• Mastery of modern deep learning frameworks such as PyTorch and extensive hands-on experience with modern architectures (Transformers, LLMs).
• Proven experience with the modern LLM stack and a strong understanding of LLM guardrails and alignment techniques.
• Demonstrated history of successfully transitioning complex AI research or prototypes into high-throughput, low-latency production systems at scale.
• Advanced skills in Python and standard software engineering workflows, with experience deploying models using high-performance inference servers such as vLLM or Triton.
• Exceptional ability to distill complex statistical and architectural concepts for non-technical stakeholders and partner effectively with cross-functional executive leadership.
