Job description

Who We Are

Healthcare needs a better rhythm: one that keeps care continuous and deeply human. Heidi is building an AI Care Partner that works alongside clinicians to make that possible.

We’re a team of doctors, engineers, designers, researchers, and creatives building tools that help clinicians stay focused on what matters most: their patients.

In just 18 months, Heidi has given back more than 18 million hours to healthcare professionals — supporting 73 million patient visits in 116 countries. Today, more than two million patient visits each week are powered by Heidi worldwide.

Backed by nearly $100 million in funding, we’re growing in the US, UK, Canada, and Europe, partnering with leading health systems including the NHS, Beth Israel Lahey Health, and Monash Health.

The Role

Working closely with the respective Engineering Manager, you’ll be a Senior/Intermediate Software Engineer who designs and scales the services that power our AI-driven products

What you’ll do

• Architect and build backend services that power LLM-based agents and clinical automations.

• Design robust APIs & data models that are secure, observable and easy for other teams to extend.

• Optimise performance and cost— profile hot paths, tune databases and right-size cloud resources.

• Automate quality: write unit / integration tests, craft alerts and own on-call runbooks so clinicians can trust every interaction.

• Partner with product, design and other engineers to ship new capabilities from concept to production in weeks, not quarters.

What we’re looking for

• Mastery of software-engineering fundamentals ; Python is our primary language, but you move fluently between technologies when the problem demands.

• Deep database expertise —schema design, query optimisation and scaling for both relational and NoSQL stores.

• Cloud fluency (GCP or AWS): containers, CI/CD, infrastructure-as-code, security and observability.

• Track record of shipping and operating systems at scale with high reliability.

• Rigorous testing, code-review and documentation habits that elevate team standards.

• Bonus points: hands-on work with AI/LLM services or real-time audio/streaming pipelines.

The way we work

1. Build to Last

We design for safety and reliability so clinicians, patients, and our teams can trust what we build every day.

2. Own Your Practice

Ideas rise on merit, not title, and everyone shares responsibility for the standards we set together.

3. Move Fast, Stay Steady

We move quickly but never at the cost of trust. Progress only matters if people can depend on what we make.

4. Make Others Better

Honest feedback, steady support, and shared growth keep our teams improving together.

Why you will flourish with us

• Flexible hybrid working environment, with 3 days in the office.

• A generous personal development budget of $500 per annum

• Learn from some of the best engineers and creatives, joining a diverse team

• Become an owner, with shares (equity) in the company, if Heidi wins, we all win

• The rare chance to create a global impact as you immerse yourself in one of Australia’s leading healthtech startups

• If you have an impact quickly, the opportunity to fast track your startup career!

Heidi is dedicated to creating an equitable, inclusive, and supportive work environment that brings people together from diverse backgrounds, experiences, and perspectives. Our strength is in our differences. We’re proud to be an equal opportunity employer and welcome all applicants as we’re committed to promoting a culture of opportunity for all.
