Are you looking for the next opportunity to revolutionize an industry? If so....

Entertainment Partners (EP) is seeking a Senior Software Engineer specializing in AI and Machine Learning to join our AI Services organization. This role sits at the intersection of applied ML engineering, LLM product development, and production-grade system design. The AI Engineer is responsible for building, training, evaluating, and deploying AI/ML models and agentic systems that power EP's intelligent product suite - including Rosey Intelligence, Project Florence, and EP Answers. The ideal candidate brings deep hands-on expertise in PyTorch, transformer architectures, and the full ML lifecycle, combined with the software engineering discipline required to ship reliable AI products at scale in a production entertainment technology environment.

KEY RESPONSIBILITIES

In addition to the following, other duties may be assigned to meet business needs.

AI / ML Engineering

• Design, develop, train, fine-tune, and evaluate machine learning models using PyTorch and associated ecosystem libraries (torchvision, torchaudio, torch.nn, torch.optim).
• Build and maintain ML training pipelines, experiment tracking workflows, and model evaluation frameworks.
• Implement transformer-based models and large language model (LLM) integrations for production use cases including NLP, information extraction, classification, and generation.
• Apply parameter-efficient fine-tuning techniques (LoRA, QLoRA, PEFT) to adapt foundation models for EP-specific domains (payroll, residuals, production management).
• Design and implement RAG (Retrieval-Augmented Generation) architectures using vector databases (pgvector, Pinecone, Weaviate) and semantic search pipelines.
• Optimize model inference for latency and throughput; implement quantization, batching, and caching strategies for production serving.
• Develop and maintain AI evaluation frameworks - including automated evals as unit tests - to ensure model behavior is reliable, safe, and production-grade.

LLM Integration & Agentic Systems

• Design and implement LLM-powered agentic workflows using LangChain, LangGraph, and EP's internal MCP (Model Context Protocol) server architecture.
• Build multi-step reasoning pipelines, tool-calling agents, and autonomous task execution systems that integrate with EP's enterprise data and product APIs.
• Implement prompt engineering strategies, few-shot templates, chain-of-thought scaffolding, and structured output validation.
• Apply and maintain EP's AI quality engineering (QE) standards including failure taxonomy, runtime guardrails, and evidence-driven release gates.
• Contribute to EP's Enterprise Context Engine - the governed, zero-data-retention AI context layer exposed via MCP to Tabnine Agent and Claude Code.
• MLOps & Production Engineering
• Build and maintain MLOps infrastructure for model training, experiment tracking (MLflow, Weights & Biases), versioning, and deployment.
• Containerize and deploy ML services using Docker and Kubernetes; integrate with CI/CD pipelines (GitHub Actions, Azure DevOps).
• Monitor model performance in production; implement drift detection, feedback loops, and automated retraining triggers.
• Ensure AI systems meet EP's security, privacy, and compliance requirements including data minimization and access control for sensitive payroll data.
• Collaborate with the data engineering team to design and maintain feature stores, data pipelines, and training data infrastructure.

Collaboration & Technical Leadership

• Partner with the Chief Architect AI & Data and CAIO to define AI architecture patterns and best practices for the EP engineering organization.
• Collaborate with product managers, UX designers, and full stack engineers to translate AI capabilities into well-designed product features.
• Conduct code reviews for AI/ML code with a focus on reproducibility, correctness, and production readiness.
• Mentor engineers across the organization in AI engineering fundamentals, LLM integration patterns, and responsible AI practices.
• Stay current with the rapidly evolving AI/ML landscape; evaluate new models, frameworks, and techniques for potential application at EP.
• Contribute to EP's PE AI Maturity Scorecard (S1-S3) by advancing the organization's AI capability maturity.
• Represent EP's AI engineering practices in Architecture Review Board discussions.
