About Us

At Sully.ai, We’re Building the Most Impactful Healthcare Company on Earth

We believe that access to a great doctor is a basic human right. Today, that’s not a reality. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

Our Mission:

One Human, One Doctor. We build AI teammates that augment clinicians — scribes, nurses, receptionists, translators — all powered by our own world-class models and deployed in real-world care.

Our Traction

  • 450+ organizations signed 16 months
  • AI agents cut admin by ~2.8 hours daily and reduce onboarding 85%.
  • 5M+ Clinical Tasks completed to date, serving 36+ specialties.
  • Raised $25M from YC, Eric Yuan, Amity, Semper Virens
  • Patented AI architecture (MedCon-1) outperforms GPT-4.5, Gemini, Claude on clinical reasoning tasks

Sully requires A-players capable of 4 months = 1 year output.

What You’ll Do:

Own the strategy, design, and execution of all platform integrations that connect Sully.ai’s AI medical employees with major EHRs, partner APIs, and healthcare data standards. Build and scale a high-performing team, work closely with Product, Clinical, Security, and Customer Success, and ensure integrations are robust, secure, HIPAA compliant, and loved by customers.

What You Must Bring:

  • 6+ years of software engineering, including 3+ years managing and scaling teams in high-growth early stage startups.
  • Deep integrations experience across industries with the ability to quickly master healthcare data standards and EHRs.
  • Strong system design skills: microservices, REST or gRPC, message buses like Kafka or RabbitMQ, and SQL or NoSQL design.
  • Hands-on coding in Python, Node.js, or TypeScript. Familiarity with React and TypeScript integration patterns is a plus.
  • CI/CD and cloud expertise: GitHub Actions or Jenkins, Docker and Kubernetes, AWS or GCP or Azure.
  • Security and compliance knowledge: HIPAA and SOC 2, security reviews, threat modeling.
  • Excellent communication with technical and non-technical stakeholders.
  • Experience at a Series A or B AI or healthcare startup.
  • Working knowledge of ML, AI, and LLMs.

First-Month Focus

  • Audit current integrations, reliability, and security posture. Define and publish SLAs and on-call runbooks.
  • Finalize a 12-month integration roadmap and target list across EHRs and partner APIs.
  • Ship an SDK and sample app MVP for partner onboarding. Kick off hiring for two key roles.

90 Day OKRs

  • Deliver one net-new EHR connector to production or pilot, and set a repeatable template to hit Q4 target of 5 integrations.
  • Establish gold-standard CI/CD and observability: p95 deploy time under 15 minutes, error budget policy in place, on-call rotation running.
  • Reduce integration incident rate and MTTR by 30 percent through automated monitoring, alerting, and self-healing.
  • Define and drive a unified integrations strategy across FHIR, HL7, DICOM, and custom partner APIs.
  • Lead design and hands-on development of core connectors for Epic, Cerner, Athenahealth, Meditech, and others.
  • Recruit, mentor, and grow an integrations and reliability engineering team. Partner cross-functionally to prioritize the roadmap and meet HIPAA and SOC 2 requirements.
