Job description

We’re Heidi. We're building the future of healthcare by giving every clinician the earth's finest AI Care Partner. In just 18 months, our clinical AI products have absorbed the administrative chaos of 73 million patient visits. Today, we support over 2.5 million patient sessions a week across 190+ countries. Healthcare systems are failing us; clinicians spend more time on documentation than on patients, and the human connection that makes medicine worth practicing is eroding. Our mission is simple: double the world’s healthcare capacity and strengthen the human connection at its heart. We found product-market fit with a freemium medical scribe that clinicians love. Now, we're expanding. Every task a clinician hands to Heidi is a patient who feels more attended to, a health system unclogged, and a clinician who gets to be a clinician again. If you don’t choose easy and you want to build something way bigger than yourself then, choose the challenge, choose Heidi. 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 Ultimately, you will have the opportunity to work closely with the engineering leadership behind Heidi, developing desktop products that will change the face of healthcare.

What you’ll do

Ultimately, you will have the opportunity to work closely with the engineering leadership behind Heidi, developing desktop products that will change the face of healthcare.

• 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 you'll need

• 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.

How we show up

• Build for the next decade, not next quarter. Our targets are outrageous on purpose. The world's health doesn't have the luxury of incrementalism.
• Lead, don't wait. We treat tomorrow's problems today. Sometimes we build what's needed before it's wanted, and we're fine with that.
• Follow the evidence. Trust the patient. We pursue truth relentlessly. But when the subjective and objective disagree, we treat the patient, not the numbers. Ego is a comorbidity we can't afford.
• Own the outcome. Everyone here carries the company. Raise problems with solutions, solve them end-to-end, and never be a bystander.
• Ship, measure, go again. A button today, a workflow tomorrow. More iterations beat better planning. We're precise at pace, not reckless.
• Live in clinicians' reality. Not the ideal workflow, the twenty-patients-before-lunch actual one. We build for exhausted humans, and we'd better be decent ones while we do it.

Why Heidi?

You’ll join a team focused on real-world impact over imaginary valuations and glos
