Job Description:

Accountabilities

• Lead UI Modernization Initiatives
  Drive the migration of legacy UI codebases into newer, scalable platforms (e.g., QT or equivalent). Use AI‑powered code‑transformation and refactoring tools to accelerate modernization efforts.
• Define Future‑Facing User Experiences
  Ensure Lattice EDA tools deliver intuitive, coherent, and productive user experiences across platforms—enabling engineers to design, debug, and optimize FPGA systems with ease.
• Cross‑Functional Architectural Ownership
  Translate marketing requirements into UI architecture, UX flows, interaction models, and functional specifications. Own the design intent throughout implementation.
• Mentorship & Technical Leadership
  Guide junior UI engineers, promote best practices, and foster a culture of innovation and continuous improvement in UI engineering and UX design.
• UX and Visual Design Excellence
  Elevate the aesthetic and functional quality of the Lattice EDA suite, including layouts, color systems, iconography, and design patterns that reflect contemporary standards.
• Accessibility & Inclusive Design
  Champion accessible UI development—including disability‑friendly interactions, optimized workflows for diverse user needs, keyboard‑only navigation, contrast‑optimized themes, and screen‑reader compatibility.
• Workflow Optimization for Power Users
  Reimagine and streamline engineer workflows through thoughtful interaction design, responsive UI behaviors, automation‑driven assistance, and human‑centered UX optimizations.
• User Research & Usability Testing
  Identify opportunities for user studies, conduct heuristic evaluations, gather real‑world feedback, and iteratively enhance UI designs.
• Maintain High Engineering Standards
  Ensure performance, stability, scalability, and maintainability of UI architectures. Establish robust design documentation and technical guidelines.
• Drive Process Improvements
  Contribute to the Spec and Plan process and continuously improve development methodologies.

Qualifications

• BS/MS/PhD in Computer Science, Electrical Engineering, HCI, or related field
• 15+ years of experience in UI engineering for complex systems such as EDA tools, CAD applications, modeling environments, or other professional engineering software.
• Experience modernizing large legacy UI codebases, including use of AI‑assisted refactoring, code translation models, or automation‑based transformation tools.
• Strong UI architecture expertise across one or more modern environments (e.g., C++, QT, cross‑platform UI systems).
• Deep understanding of UX principles, human‑computer interaction, information hierarchy, interaction models, and end‑to‑end workflow design.
• Experience with scripting languages such as Python, TCL, or shell scripting.
• Knowledge of FPGA or ASIC design workflows is a strong plus.
• Background in performance‑sensitive UI engineering (e.g., visualization, large data models, graphical workflows) is desirable.
• Independent problem‑solving ability, attention to detail, and proven project leadership.
• Excellent communication and collaboration skills, with the ability to work across multifunctional teams.
