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.

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
