Heidi Health is building AI Care Partners for clinicians to reduce administrative burden and strengthen patient care. The company has achieved product-market fit with a freemium medical scribe used across 190+ countries, supporting 2.5 million patient sessions weekly.
As a Mid Level AI Models Engineer, you will own delivery across four core areas: model customization, deployment and inference, agent systems, and customer delivery. You should bring strong experience in at least two of these domains.
Model Customization: Convert customer use cases into training and evaluation plans, select appropriate data and models, fine-tune for specialized domains, and iterate based on testing and production feedback.
Deployment and Inference: Design cost-effective cloud or on-premises deployment strategies, select infrastructure and serving configurations, optimize reliability and latency, and build monitoring and recovery processes.
Agent Systems: Build agent workflows around language models, integrate with customer data and existing systems, and add production-grade controls and observability.
Customer Delivery: Understand customer requirements and constraints, communicate trade-offs between quality, cost, privacy, and complexity, and guide solutions from discovery through production launch.
Required qualifications include practical experience building or operating production AI systems, solid software engineering or machine learning skills, familiarity with open-weight language models and the modern LLM ecosystem, and ability to balance model quality, cost, latency, and reliability. You should communicate clearly with both technical and non-technical stakeholders and work through ambiguous requirements.
Heidi values building for long-term impact, leading proactively, following evidence, owning outcomes end-to-end, shipping iteratively, and understanding clinician workflows. The company offers competitive benefits including learning budget, wellness allowance, home office budget, generous parental leave, fertility support, and equity.
