• Proven experience training, evaluating, and deploying custom ML models in production environments
• Hands-on experience with both LLM-powered applications and traditional ML model development
• Deep understanding of model architectures, training methodologies, and optimization techniques
• Strong software engineering fundamentals, including system design, APIs, and cloud architectures
• Experience leading technical initiatives across teams or operating at staff or tech lead level
• Active hands-on coder with ongoing experience writing production code and training models
• Expert-level knowledge of ML fundamentals, including neural networks, transformers, and optimization algorithms
• Deep experience with deep learning frameworks such as PyTorch, TensorFlow, or JAX
• Experience with LLM application patterns including RAG, prompt engineering, fine-tuning, and agentic architectures
• Proficiency with distributed training, GPU optimization, and experiment tracking tools
• Strong foundation in statistics, probability, and mathematical optimization
• Experience with advanced ML architectures such as transformers, diffusion models, graph neural networks, or reinforcement learning
• Knowledge of vector databases, embeddings, and semantic search technologies
• Experience in data engineering for ML, including feature stores, data pipelines, and data quality practices
• Understanding of MLOps practices such as model monitoring, A/B testing, shadow deployments, and versioning
• Cloud experience (AWS, Azure, or GCP) supporting ML workloads at scale
• Strong technical communication skills with ability to explain complex concepts to diverse audiences
• Pragmatic, collaborative leadership style with comfort operating in ambiguity
• Experience working in enterprise SaaS environments with mature products

Nice To Haves

• Publication record (academic papers, patents, or significant open-source contributions) is a strong plus

Responsibilities

• Architect and implement AI-powered features across the SaaS platform, including agentic workflows, intelligent data extraction, and analysis capabilities
• Lead research and development of custom AI/ML models tailored to the commercial real estate domain
• Evaluate fine-tuning foundation models versus building domain-specific models from scratch
• Establish technical standards, patterns, and best practices for AI/ML development across feature teams
• Lead hands-on development of complex AI systems, including LLM integrations, RAG architectures, and multi-agent orchestration
• Design and implement model training pipelines, experiment tracking, and model versioning infrastructure
• Make build-versus-buy decisions for AI tooling and frameworks, balancing innovation with pragmatism
• Design scalable infrastructure for AI workloads, including model serving, inference optimization, and GPU resource management
• Partner with engineering and architecture leaders to identify AI opportunities and guide implementation
• Collaborate with Platform, Data, and Analytics teams to ensure access to high-quality, unified data
• Work with product managers to translate business requirements into technical AI solutions
• Mentor engineers on AI/ML techniques, prompt engineering, and agentic frameworks
• Drive the technical roadmap for AI capabilities across applied LLM work and custom model development
• Lead research initiatives advancing CRE-specific AI applications
• Champion AI adoption through internal knowledge-sharing initiatives such as the AI Guild
• Evaluate emerging AI technologies and research, leading proofs-of-concept where appropriate
• Establish experimentation frameworks for rapid iteration and A/B testing of AI features
• Contribute to the AI/ML community through publications, blogs, or open-source work
• Define governance models, quality gates, testing strategies, and safety measures for AI systems
• Create documentation and runbooks to support reliable operation of AI-powered features
• Balance rapid innovation with responsible AI practices and risk management
