We are seeking an expert practitioner and thought leader to join our team as a Senior AI Platform Lead. This is a senior, hands-on technical leadership role for a seasoned expert who will be instrumental in shaping and scaling our Artificial Intelligence practices across the enterprise. You will be responsible for defining best practices, building core frameworks, and establishing the standards for how we build, evaluate, and deploy next-generation AI solutions.
The ideal candidate is not just a strategist but a deep, hands-on practitioner with a passion for solving complex problems. You have extensive, practical experience with the latest AI tools and techniques. You are an expert in the science of AI evaluation and have built systems to measure and validate AI performance at an industrial scale. This role is for a practical problem-solver who can lead by example and guide our engineering community toward building robust, reliable, and scalable AI applications.
Key Responsibilities:
AI Practice Leadership: Act as a senior technical authority to help define and scale our AI engineering practices. Create reference architectures, development blueprints, and best-practice guidelines for building advanced AI solutions.
Hands-On Prototyping & Framework Development: Lead the design and development of core AI frameworks and libraries. Build production-quality proof-of-concepts and reference implementations for complex patterns like advanced RAG pipelines and multi-agent systems.
AI Evaluation at Scale: Architect and implement a comprehensive, enterprise-grade AI evaluation framework. This includes defining key metrics, developing automated testing pipelines, and establishing processes to continuously evaluate the performance, accuracy, safety, and cost of our AI models and systems.
Technical Mentorship & Evangelism: Serve as a senior mentor to AI engineers across the organization. Evangelize best practices in AI engineering, MLOps, and system evaluation through workshops, documentation, and direct consultation.
Expert Consultation: Act as the go-to expert for application teams on advanced AI topics. Provide deep technical guidance on architecture, tool selection, and implementation challenges related to RAG, agentic systems, and large-scale deployment.
