Principal Software Engineer - UI/UX (Qt/QML)

Principal Software Engineer – UI/UX (Qt/QML)

At Medtronic, you can begin a life-long career of exploration and innovation, while helping champion healthcare access and equity for all. You'll lead with purpose, breaking down barriers to innovation in a more connected, compassionate world.

As a Principal Software Engineer – UI/UX (Qt/QML) you will set the technical direction for the Prism Mapping application UI — the architecture that lets clinicians drive an extremely complex real-time medical system without ever feeling its complexity. You'll lead Qt/QML application architecture across the product, partner closely with UX design leadership and product to shape multi-release direction, and drive standards for interaction patterns, state management, accessibility, and performance in a regulated environment. You'll mentor senior UI engineers across teams, drive root cause on the hardest UI problems — the ones tangled up with real-time data, GPU rendering, and clinical workflow — and raise the engineering bar for UI software in a medical device, where every interaction has to be fast, clear, and correct.

About the Affera Prism Mapping System

The Affera Prism Mapping System is an advanced electrophysiology mapping platform used by physicians to diagnose and guide the treatment of cardiac arrhythmias. It captures and processes signals from inside the beating heart, builds detailed real-time three-dimensional maps of cardiac anatomy and electrical activity, and presents that information to clinicians and mapping specialists during live procedures. Engineers on this team build the software that makes that possible — from the runtime and data pipelines that move signals in milliseconds, to the algorithms that turn raw signals into clinically meaningful information, to the visualization and UI surfaces clinicians rely on in the lab.

Primary Responsibilities

• Lead architecture for the Prism Mapping application UI — Qt/QML structure, state management, navigation, theming, accessibility, and performance.
• Define multi-release direction for the UI in partnership with UX design leadership and product.
• Set the engineering bar for UI code on clarity, safety, testability, and performance under clinical conditions.
• Lead the design and delivery of major subsystems, cross-cutting architecture, or large technical initiatives.
• Exercise broad technical judgment in defining approaches to complex system and architectural problems with limited oversight.
• Drive technical alignment across software, systems, quality, product, and other cross-functional teams.
• Establish and promote software design patterns, engineering standards, and development best practices.
• Provide technical leadership across teams through mentoring, design reviews, and guidance on critical engineering decisions.
• Identify and drive improvements in architecture, development processes, and system design.
• Shape the technical roadmap and architectural direction for major subsystems or product capabilities.
• Communicate complex technical tradeoffs, risks, and recommendations to stakeholders across functions.

Required Qualifications

• Bachelor's degree and a minimum of 7 years of relevant experience
• OR Master's degree with a minimum of 5 years of relevant experience
• OR PhD with 3 years relevant experience

Preferred Qualifications

• Deep expertise architecting Qt/QML applications at scale — state management, threading, performance, accessibility, theming.
• Track record of shaping UI architecture for complex technical or clinical products across multiple releases.
• Strong understanding of how UI architecture interacts with real-time data, GPU rendering, and clinical workflow constraints.
• Deep expertise in Python and C++ and in software architecture for complex, multi-component systems.
• Proven experience delivering complex, real-time, device-integrated, or networked systems.
• Experience leading large, complex, cross-functional technical initiatives.
• Experience defining architecture, standards, or technical direction across multiple components or teams.
• Experience solving ambiguous, high-impact technical problems spanning multiple domains or subsystems.
• Experience influencing technical decisions beyond immediate team boundaries.
• Experience in regulated environments preferred.
• Advances how the team uses AI tools — introduces new approaches that raise team productivity and quality.
