Principal AI Applied Engineer

Become a part of our caring community
Every large organization is making critical decisions today about how it will leverage AI over the next decade. Few have leaders who can both define that vision and demonstrate its viability through hands-on engineering. This role requires both.

We build the platform that transforms millions of clinical documents into trusted, actionable data. Our systems use large language models (LLMs) to read medical records, extract structured facts, answer complex questions with citations to source documents, and route difficult cases to human experts. These capabilities support decisions that impact real healthcare outcomes for members.

As a Principal AI Applied Engineer, you will define the technical strategy, architectural standards, and long-term vision for AI-enabled products across the organization. You will influence enterprise-wide decisions regarding AI platforms, model strategies, engineering standards, and technology investments while remaining deeply hands-on in prototyping, experimentation, architecture, and software development.

This is the highest-level individual contributor role within the AI Applied Engineering organization. Success requires exceptional technical depth, organizational influence, strategic thinking, and the ability to translate emerging AI capabilities into scalable, reliable, and responsible production systems.

Why Join Us

• Shape the long-term AI architecture and engineering direction for a large enterprise healthcare organization.

• Influence how AI-enabled products are designed, built, evaluated, deployed, and governed across multiple teams.

• Drive strategic decisions involving models, vendors, platforms, infrastructure, and shared capabilities.

• Prototype and validate emerging technologies before the organization invests at scale.

• Establish engineering standards and platform capabilities that will influence the business for years to come.

• Solve complex challenges involving trust, explainability, compliance, reliability, and operational excellence in AI systems.

• Work on systems that process healthcare information at significant scale and directly support member outcomes.

• Remain hands-on with architecture, software development, experimentation, and technical problem solving.

Key Responsibilities

• Define and drive the long-term technical strategy, reference architecture, and technology roadmap for AI-enabled products and platforms.

• Establish architectural patterns and best practices for retrieval systems, LLM orchestration, agentic workflows, human-in-the-loop processes, evaluation frameworks, and AI governance.

• Lead organization-wide technical decision-making regarding model strategy, vendor selection, platform investments, build-versus-buy decisions, and shared infrastructure capabilities.

• Design and champion scalable architectures that balance reliability, performance, security, compliance, maintainability, and cost efficiency.

• Establish engineering standards for evaluation, observability, model lifecycle management, responsible AI practices, and operational excellence.

• Build prototypes, proofs of concept, and reference implementations that de-risk emerging technologies and strategic platform investments.

• Lead cross-functional architecture reviews and provide technical guidance across multiple engineering teams.

• Mentor Lead Engineers, Senior Engineers, and emerging technical leaders through architecture reviews, design feedback, coaching, and technical sponsorship.

• Develop and communicate technical roadmaps aligned with business strategy and organizational objectives.

• Partner with executive leadership to translate business priorities into technical strategies and communicate technical opportunities, risks, and tradeoffs.

• Represent engineering in strategic vendor evaluations, compliance discussions, governance reviews, and enterprise planning initiatives.

• Drive adoption of common platforms, standards, and engineering practices across teams.

• Ensure AI systems are designed and operated in accordance with privacy, security, compliance, governance, and auditability requirements.

Required Qualifications

• Bachelor's degree in Computer…
