What this job asks for AI summary
A founding engineering role on a newly formed Agentic AI team, focused on building a production-grade platform for autonomous, multi-step medical reasoning workflows from the ground up. Day-to-day work spans designing multi-agent orchestration patterns, integrating with EHRs and imaging pipelines, and implementing safety guardrails suited to FDA-cleared software. The role suits experienced engineers with hands-on LLM and agentic architecture background who are comfortable operating in greenfield, ambiguous environments.

Why we read it this way (6)
This posting covers BOTH Senior (5+ years, $180K–$215K) and Staff (8+ years, $200,750–$250,922) levels simultaneously. The level advertised in the title is set to Senior (the lower of the two) and the overall years minimum reflects the Senior minimum of 5 years; the Staff band's 8-year floor and higher salary ceiling are captured in the comp range max.
The compensation range spans both levels: $180,000–$215,000 for Senior and $200,750–$250,922 for Staff. The min/max here represent the full combined range across both levels, plus cash bonus and equity.
Heartflow is headquartered in Redwood City, CA (San Jose-Sunnyvale-Santa Clara CBSA). The posting is tagged #LI-Hybrid, so it is not fully remote.
The SOC classification is Medium confidence: the role is primarily software engineering (building an agentic AI platform), but has a meaningful AI/ML dimension that could also point to Data Scientists (15-2051). Software Developers is the better fit given the emphasis on platform architecture, production deployment, and engineering execution.
'Orchestration frameworks' and 'agentic AI frameworks' are listed as a single required skill — the JD does not name a specific tool (e.g., LangChain, LlamaIndex, AutoGen), so the skill is labeled generically per the posting's language.
Fine-tuning appears only under the Nice-to-Have section alongside prompt engineering and RAG optimization; all three are marked preferred accordingly.
