Jobtailor; Massachusetts; On-site; USD 140,000 - 190,000; Full time

Job summary

Jobtailor is seeking a senior UI/architecture leader to drive Prism Mapping UI design and implementation. You will own Qt/QML architecture, state management, theming, accessibility, and performance for a complex, real-time clinical application.

You will partner with UX, product, and cross-functional teams to define multi-release UI direction, uphold coding standards, and mentor engineers across multiple subsystems. Strong Python/C++ expertise and regulatory context are preferred.

Qualifications

• Bachelor's degree and 7+ years of experience, or a Master’s/PhD with fewer years.
• Deep expertise architecting Qt/QML applications at scale with state management.
• Strong track record shaping UI architecture for complex technical or clinical products across releases.
• Understanding of UI interaction with real-time data, GPU rendering, and clinical workflows.
• Proficiency in Python and C++ for multi-component systems.
• Experience delivering complex, real-time, device-integrated, or networked systems.

Responsibilities

• Lead architecture for the Prism Mapping 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.
