    Compensation: $200,000–$350,000 + Equity

    Overview

    We’re hiring a world-class Senior AI Engineer to build cutting-edge systems for an AI doctor platform. You’ll design and deploy safety-critical, production AI that delivers diagnostic reasoning, chronic disease management, and seamless healthcare data processing—all with rigorous accuracy and clinical safeguards.

    What You’ll Build

    Core AI Architecture

    • Multi-agent consensus: specialized models debate cases before reaching conclusions.

    • RAG at scale: pipelines ingesting thousands of clinical guidelines curated for LLMs.

    • Real-time inference: optimize latency and throughput for millions of daily consultations.

    • Domain workflows: custom reasoning chains for condition- and specialty-specific care.

    Clinical Data Systems

    • HIPAA-compliant NLP: extract structured data from patient conversations.

    • EHR connectivity: integrate with QHINs for automated retrieval/reconciliation.

    • Intelligent triage: route cases between AI and clinicians via complexity scoring.

    • Documentation: generate notes that conform to provider protocols and coding rules.

    Safety & Scale Infrastructure

    • Emergency detection with sub-second human escalation.

    • Validation layers targeting 99%+ plan accuracy vs. clinical standards.

    • Distributed systems for explosive peak loads and rapid user growth.

    • Fail-safes for regulated, critical-path decisions.

    You’ll also tackle voice/video interfaces, multilingual medical NLP, predictive health modeling, and the platform foundation for the next billion patient interactions.
