We are seeking a Lead Software Engineer to design, build, and scale next-generation agentic AI systems and advanced solutions that improve healthcare delivery and operations.
In this individual contributor (IC) leadership role, you will operate as a hands-on technical expert, driving architecture, development, and deployment of complex AI-powered solutions. You will architect end-to-end question answering and multiagent workflows, integrate with our internal AI platform (e.g., UAIS), and ensure responsible, compliant use of AI in a regulated environment (HIPAA). The ideal candidate combines deep software engineering expertise with hands-on experience in LLMs, RAG, agent/tool use, and evaluation on modern cloud and data platforms.
This role is ideal for someone who thrives on solving complex problems, enjoys working at the intersection of AI/ML and distributed systems, and wants to make a meaningful impact in a highly regulated, mission-driven environment.
You'll enjoy the flexibility to work remotely * from anywhere within the U.S. as you take on some tough challenges. For all hires in the Minneapolis or Washington, D.C. area, you will be required to work in the office a minimum of four days per week.
Primary Responsibilities:

• Agentic AI Architecture & Delivery
  • Design and implement (multi) agentic workflows where LLMs plan, decompose tasks, invoke tools/APIs, and synthesize answers across heterogeneous data sources and services
  • Build retrieval augmented generation (RAG) and hybrid search pipelines to power robust question answering over clinical and operational data
  • Design, code, test, document, and maintain high quality, scalable Big Data and cloud solutions
  • Develop scalable microservices and APIs for integrating agent capabilities into clinician tools and internal apps
  • Create prototypes/POCs and conduct design/code reviews to derisk delivery and raise engineering quality
• LLMs, GenAI & Model Adaptation
  • Leverage and adapt LLMs; perform prompt engineering, grounding, guard railing, and domain adaptation for healthcare terminology and tasks
  • Design intelligent frameworks and finetune models for compliance, accuracy, and ethical standards
  • Establish evaluation frameworks (automatic + human in the loop) to measure faithfulness, helpfulness, bias, toxicity, privacy leakage, and overall quality
• Data & Platform Engineering
  • Partner with data engineering to build feature/retrieval stores, embeddings pipelines, and ETL/ELT jobs on Spark/Databricks; design analytics models and rules engines
  • Define and develop APIs for integrations across the enterprise; improve data access patterns for low latency inference
• Delivery, MLOps & Reliability
  • Own MLOps/LLMOps: CI/CD for models/prompts, automated tests (unit/contract/eval), versioning, lineage, rollback; enable blue/green or canary releases
  • Instrument SLOs/SLIs (latency, availability, hallucination/defect rate) and cost KPIs (tokens, GPU hours) with dashboards and alerts
  • Lead production deployments on internal platforms (e.g., UAIS) with solid observability, reliability, and cost controls
• Security, Privacy & Compliance
  • Champion HIPAA and regulated industry controls; integrate access controls, PHI/PPI safeguards, data minimization, encryption, and auditability
  • Collaborate with legal, compliance, and clinical safety to operationalize Responsible AI principles
• Product, Estimation & Collaboration
  • Analyze and define customer requirements; assist in defining product technical architecture and delivery roadmaps
  • Provide effort estimates and inputs for resource planning; collaborate with QA, architecture, and peer teams
  • Write technical documentation, support production, and mentor engineers, and keep skills current through continuous learning

You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role as well as provide development for other roles you may be interested in.
