Senior Software Engineer (Desktop App)

Department: Engineering

Location: Sydney

Employment Type: FullTime

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

As a Senior Software Engineer in Desktop Applications, you’ll play a key role in shaping Heidi’s cross-platform desktop products, designing robust architectures and building reliable systems that scale across operating systems.

You care deeply about product quality, performance, and user experience, and you’re passionate about crafting intuitive, high-quality desktop applications that clinicians around the world can depend on. You are comfortable working across the stack, from Rust-based system components to web-based interfaces, and you take pride in owning complex problems end to end, from design through to delivery and long-term maintainability.

Your superpower is turning complex product and platform requirements into elegant, reliable desktop software. You bridge low-level systems engineering with delightful user experiences, and you thrive in environments where autonomy, ownership, and impact matter more than hierarchy.

You enjoy working close to the problem space, audio, performance, AI workflows, and cross-platform constraints, and you are excited by the challenge of building an AI-powered healthcare product that works seamlessly across operating systems and geographies.

What you'll do:

• Lead the development of Heidi’s cross-platform desktop applications using Tauri, Rust, and Next.js, shipping production-grade software on macOS and Windows (Linux a plus).

• Own the end-to-end desktop experience, from system architecture and native integrations to frontend implementation, performance, and long-term maintainability.

• Design and build high-performance Rust components powering real-time audio capture, transcription pipelines, local state management, and secure system interactions.
  Build reliable, well-designed interfaces between Rust backends and web-based frontends, with a strong focus on safety, correctness, and developer experience.

• Improve the reliability and accuracy of core experiences such as real-time transcription, AI-assisted note generation, offline/online sync, and integrations with healthcare systems.

• Design and implement end-to-end (E2E) and integration testing strategies for desktop apps, covering Rust services, frontend interactions, and cross-process communication

• Actively leverage AI-assisted development workflows to accelerate design, implementation, debugging, and testing across the desktop stack.
  Advocate for excellent engineering practices, performance, reliability, and accessibility in desktop applications.

• Collaborate across product, design, ML, and backend teams to deliver features that have a real impact on how healthcare is delivered.

• Contribute to improving Heidi’s desktop engineering ecosystem and culture as the team continues to grow.

What we’re looking for

• 5+ years of professional software engineering experience, with clear ownership of complex systems or products.

• Strong experience with systems-level programming (Rust preferred; C++ or Go acceptable), including performance, memory management, and concurrency.

• Hands-on experience building or maintaining desktop applications (Tauri, Electron, or native), with an understanding of OS-level concerns such as file systems, permissions, packaging, and updates.

• Experience with modern frontend technologies such as React / Next.js, and comfort working across the frontend–backend boundary.

• Comfortable owning ambiguous, high-impact technical problems and driving them to resolution with a high degree of autonomy.

• Strong product intuition and a user-centric mindset, particularly for tools used daily by professionals in high-stakes environments.

• Demonstrated ability to embrace AI as a force multiplier in software engineering—using it thoughtfully for system design, problem-solving, debugging, testing, and improving overall development velocity.

Bonus:

• Experience designing or maintaining CI/CD pipelines for desktop or cross-platform applications.

• Hands-on experience with E2E and integration testing for desktop apps (e.g. Playwright, WebDriver-based tools, or custom Rust test harnesses).

• Experience with real-time or low-latency systems (audio, streaming, transcription).

• Background in health tech, AI-powered products, privacy- or security-sensitive systems, or early-stage startups.

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 health-tech 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.
