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:
Cross-Functional Delivery: 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.
Architectural & Security Problem-Solving: 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.
Performance & Scale Optimization: Proactively identify technical bottlenecks and scaling opportunities, driving continuous performance and efficiency optimizations to maximize throughput, lower inference latency, and streamline compute resource utilization at scale.
Modern Engineering Best Practices: Evangelize and implement modern engineering best practices, including agentic coding workflows, reproducible research pipelines, and spec-driven development within the team.
Model Serving & Enterprise Infrastructure: Lead the architectural design and execution of large-scale enterprise systems with high-performance model serving infrastructure, ensuring seamless, scalable integration across backend security services and partner engineering teams.
Mentorship & Technical Excellence: Mentor senior and junior engineers and researchers, fostering a culture of technical excellence, algorithmic rigor, and continuous learning within the team.
Qualifications: Your Experience
Experience & Education:
8+ years of post-academic industry experience developing and deploying machine learning models in production environments, with a Ph.D. or Master’s degree in Computer Science, AI, Applied Mathematics, or a related field.
Deep Learning Expertise: Mastery of modern deep learning frameworks (PyTorch, JAX) and extensive hands‑on experience with modern architectures (Transformers, LLMs).
Generative AI & LLM Security: Proven experience with the modern LLM stack (pre‑training, fine‑tuning via LoRA/SFT, RAG) and a strong understanding of LLM security vulnerabilities, guardrails, and alignment techniques.
Research-to-Product Track Record: Demonstrated history of successfully transitioning complex AI research or prototypes into high-throughput, low-latency production systems at scale.
Engineering Proficiency: Advanced skills in Python and standard software engineering workflows, with experience deploying models using high-performance inference servers (vLLM, Triton, ONNX) and containerized orchestration (Docker, Kubernetes).
Technical Communication: Exceptional ability to distill complex statistical and architectural concepts for non-technical stakeholders and partner effectively with cross-functional executive leadership.
