About The Position

Maya HTT is seeking an experienced UI/UX consultant for a six-month engagement to define the UI/UX strategy, wireframes, workflows, and interaction patterns for a new thermal simulation technology application. This role focuses on modernizing the user experience for thermal modeling, analysis, and results interpretation, building on existing enterprise technology. The consultant will work closely with the Product Owner, software development team, and domain engineers to create an application that is intuitive, efficient, and approachable for experienced engineers, while preserving deep functionality. The ideal candidate has experience designing interfaces for technically sophisticated software such as engineering simulation, CAD, CAE, or PLM, where usability must balance with complex functionality and expert users.

Requirements

• 7+ years of UI/UX design experience
• Demonstrated experience designing complex technical or scientific software (CAE, CAD, PLM, Simulation, GIS, EDA, Industrial software)
• Portfolio demonstrating UX work for sophisticated expert-user applications rather than primarily consumer products
• Strong proficiency with Figma, Sketch, or equivalent design tools
• Ability to produce developer-ready wireframes, interaction flows, and design documentation
• Comfortable collaborating directly with Product Owners, software engineers, and technical domain experts
• Ability to improve established interaction patterns using sound UX principles, workflow analysis, and user-centered design
• Excellent written and verbal English communication skills

Nice To Haves

• Familiarity with commercial CAE environments such as Siemens Simcenter 3D, Ansys Workbench, Thermal Desktop, COMSOL Multiphysics, or similar engineering simulation tools
• Experience designing interfaces for engineering simulation applications, including thermal, structural, CFD, or systems modeling
• Experience creating design systems for TypeScript or SolidJS applications
• Basic knowledge of C or C#
• Familiarity with aerospace, satellite, or industrial thermal engineering domains
• French is an asset

Responsibilities

• Evaluate existing CAE and engineering simulation workflows to identify opportunities for improved usability, efficiency, and clarity
• Partner with the Product Owner to define the application's UX strategy, information architecture, navigation, and interaction model
• Design wireframes, interactive prototypes, and high-fidelity mockups for core engineering workflows
• Define user journeys for domain-specific interactions including thermal model definition and setup, solver configuration, and reporting
• Establish and document a scalable design system and component library appropriate for a data-dense engineering application
• Work closely with Product Owner and developers to ensure designs are practical, implementable, and consistent throughout development
• Conduct usability reviews with internal engineers and, where possible, customers or beta users
• Balance expert-user productivity with discoverability and ease of learning for newer users
• Deliver design documentation, workflows, prototypes, and handoff materials that can be maintained by the internal team
