Full job description

A Day in the Life

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

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.
