Principal AI Engineer
Job Description
The Principal AI Applied Engineer will define long-term AI technical strategy and architecture for enterprise healthcare AI-enabled products, while staying hands-on across prototyping, experimentation, and software delivery.
Role Overview
This position guides model strategy, platform direction, standards, governance, and cross-team adoption to support scalable, reliable, and responsible production AI systems. The role combines strategic architecture leadership with direct engineering involvement to advance both emerging capabilities and enterprise-grade operational readiness.
Key Responsibilities
- Define and drive long-term technical strategy, reference architecture, and technology roadmap for AI-enabled products and platforms.
- Set 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 across model strategy, vendor selection, platform investments, build-versus-buy decisions, and shared infrastructure capabilities.
- Design and promote 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.
- Develop prototypes, proofs of concept, and reference implementations to reduce risk for emerging technologies and strategic platform investments.
- Conduct 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, communicating 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 to meet privacy, security, compliance, governance, and auditability requirements.
Required Qualifications
- Bachelor’s degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
- 12+ years of software engineering experience, including extensive experience designing and operating large-scale distributed systems.
- Proven experience designing, delivering, and operating production AI-enabled platforms or products at enterprise scale.
- Deep expertise in large language model technologies, AI platform design, retrieval-augmented generation (RAG), agentic systems, orchestration frameworks, evaluation methodologies, and AI operations.
- Extensive experience designing cloud-native architectures and highly scalable, resilient systems.
- Ability to define technical direction that influenced teams, organizations, or product portfolios beyond direct reporting relationships.
- Experience establishing engineering standards, architectural frameworks, or technical platforms adopted across multiple teams.
- Strong understanding of AI operational challenges including model reliability, latency, cost optimization, governance, observability, and risk management.
- Demonstrated success influencing executive stakeholders and driving organizational decisions through technical leadership and evidence-based recommendations.
- Expert-level proficiency in Python and/or TypeScript/JavaScript.
- Ability to prototype, debug, review, and contribute code across multiple layers of the technology stack.
Preferred Qualifications
- Experience leading AI platform strategy across multiple business units or product organizations.
- Experience developing enterprise standards for AI evaluation, testing, observability, governance, and responsible AI practices.
- Expertise evaluating and managing AI vendor ecosystems across multiple model providers and platform technologies.
- Experience building shared AI infrastructure and platform capabilities consumed by multiple engineering teams.
- Experience with agentic architectures, Model Context Protocol (MCP), workflow orchestration, autonomous systems, and emerging AI frameworks.
- Experience operating AI systems at significant scale while managing performance, reliability, and cost tradeoffs.
- Experience working in regulated industries such as healthcare, financial services, life sciences, or government.
- Deep understanding of privacy, security, compliance, governance, and risk management requirements in highly regulated environments.
- Experience driving adoption of AI-assisted software development practices across engineering organizations.
- Experience advising executive leadership on emerging technologies, platform strategy, and enterprise architecture decisions.
- Exceptional communication, leadership, collaboration, and strategic problem-solving skills.
