• Design agentic workflows with task decomposition, tool and function calling, memory and state management, routing, clear boundaries, human review checkpoints, and fallback paths for high-impact decisions such as benefits verification and prior authorization
• Lead the design of APIs, services, and integrations that embed AI capabilities into existing AssistRx platforms and client-facing workflows, resolving cross-team technical dependencies
• Translate ambiguous business and clinical workflow requirements into technical strategies, designs, and production releases, taking proven pilots to scale across products and clients
• Select the right approach for each problem, including prompting, retrieval augmentation, tool use, task-specific models, and conventional software or deterministic logic when a model is not the right answer
• Author and review design documentation for AI features covering intended behavior, context and retrieval design, prompt and agent structure, evaluation approach, and fallback behavior, setting the documentation standard for the organization

AI Foundations & Platform

• Own the AI reference architecture, reusable components, and engineering standards for AI development at AssistRx, including model access, prompt and version management, and retrieval services, and drive their adoption across engineering teams
• Evaluate commercial models, AI platforms, and vendor tools, and provide build-versus-buy recommendations to the Vice President, Engineering based on quality, cost, security, and time to value
• Shape the AI technical roadmap in partnership with Product and Architecture, helping prioritize work by business value, feasibility, and risk, and maintaining the AI use case inventory and technical backlog
• Identify platform gaps and technical debt in AI systems and lead the investments needed to close them

Model Development, Evaluation & Optimization

• Select, tune, and evaluate models against defined targets for accuracy, groundedness, hallucination rate, task completion, latency, and cost
• Define the organization’s evaluation frameworks, benchmark datasets, and automated test suites that measure output quality and detect regressions before each release
• Optimize retrieval pipelines, embeddings, chunking strategies, and inference performance to improve quality and reduce cost per transaction
• Lead error analysis and human-in-the-loop review cycles with operations and clinical subject matter experts, applying findings to improve prompts, models, and guardrails
• Design and run structured experiments and A/B tests across prompts, retrieval configurations, model selection, and workflow design, and use the results to drive iteration
• Establish and enforce quality gates and regression thresholds so AI features must meet defined accuracy and safety criteria before release

Data Engineering & Integration

• Define and guide the pipelines that prepare structured and unstructured healthcare data, such as enrollment forms, payer documents, and clinical notes, for training, retrieval, and inference
• Partner with Data Engineering to define data contracts, feature sets, vector stores, and lineage for AI workloads
• Set standards for de-identification, masking, and data minimization when working with protected health information

Machine Learning Operations & Production

Support

• Set standards for CI/CD, source control, containerization, and infrastructure-as-code practices for AI workloads
• Maintain versioning, promotion, and rollback practices for prompts, agents, and model configurations, treating them as versioned artifacts alongside application code
• Define monitoring for accuracy drift, groundedness, task completion, token consumption, latency, cost, and reliability through logging, observability, and alerting
• Track and manage model and inference spend, applying caching, routing, and model right-sizing to keep AI solutions cost-effective at scale
• Serve as the escalation point for complex production issues and client-reported defects in AI-enabled features, leading root cause analysis and continuous improvement of deployed AI services

Responsible AI, Security, Privacy & Compliance

• Build solutions that satisfy healthcare privacy, data security, and regulatory requirements, including HIPAA and HITRUST
• Partner with Security and Compliance to address AI-specific risks such as prompt injection, data leakage, and insecure output handling, and to confirm vendor agreements (including Business Associate Agreements) are in place before PHI is processed
• Define guardrails, content filtering, human oversight, and audit trails appropriate to the risk profile of each use case
• Document model design, data sources, intended use, and known limitations to support internal AI governance, audits, and client due diligence

Technical Leadership & Collaboration

• Provide technical leadership across multiple teams, influencing design decisions and engineering direction without direct authority
• Mentor and coach Senior and mid-level engineers on AI development, code quality, evaluation, and design practices, and raise the overall level of AI fluency across engineering
• Lead design reviews and peer code reviews, and contribute to shared standards and reference architectures across the engineering organization
• Work with Product Management and business stakeholders to identify high-value AI use cases and define clear success measures before build begins
• Communicate AI capabilities, limitations, risks, and results in plain language to technical and non-technical audiences, including engineering leadership, executives, and clients
