Senior Software Engineer

Who are Heidi?

Heidi is building an AI Care Partner that supports clinicians every step of the way, from documentation to delivery of care.

We exist to double healthcare's capacity while keeping care deeply human. In 18 months, Heidi has returned more than 18 million hours to clinicians and supported over 73 million patient visits. Today, more than two million patient visits each week are powered by Heidi across 116 countries and over 110 languages.

Founded by clinicians, Heidi brings together clinicians, engineers, designers, scientists, creatives, and mathematicians, working with a shared purpose: to strengthen the human connection at the heart of healthcare.

Backed by nearly $100 million in total funding, Heidi is expanding across the USA, UK, Canada, and Europe, partnering with major health systems including the NHS, Beth Israel Lahey Health, MaineGeneral, and Monash Health, among others.

We move quickly where it matters and stay grounded in what's proven, shaping healthcare's next era. Ready for the challenge?

What do we believe in?

Heidi builds for the future of healthcare, not just the next quarter, and our goals are ambitious because the world's health demands it. We believe in progress built through precision, pace, and ownership.

• Live Forever -
  Every release moves care forward: measured, safe, and built to last. Data guides us, but patients define the truth that matters.
• Practice Ownership -
  Decisions follow logic and proof, not hierarchy. Exceptional care demands exceptional standards in our work, our thinking, and our character.
• Small Cuts Heal Faster -
  Stability earns trust, speed delivers impact. Progress is about learning fast without breaking what people depend on.
• Make others better -
  Feedback is direct, kindness is constant, and excellence lifts everyone. Our success is measured by collective growth, not individual output.

Our mission is clear: expand the world's capacity to care, and do it without losing the humanity that makes care worth delivering.
