Senior UX Designer

Role

Senior UX Designer responsible for shaping AI-native user experiences for Energy Exemplar’s suite (PLEXOS, Aurora, Adapt2, PLEXOS Intelligence). The role focuses on designing interfaces and visualizations for energy analysts, grid planners, market traders, and other expert users, collaborating closely with product, engineering, and domain experts.

Key Responsibilities

• Own end-to-end UX for complex, data-intensive features across the product suite from discovery through delivery and iteration.
• Apply UX heuristics and principles to reduce cognitive load in dashboards, simulation builders, and results visualizations.
• Design AI-native experiences including conversational interfaces, copilot features, intelligent recommendations, and human-in-the-loop workflows.
• Use vibe-coding and AI-assisted tools to rapidly prototype and iterate on interactive concepts.
• Conduct user research with domain experts and customers (interviews, usability testing, contextual inquiry) to inform design decisions.
• Define and maintain the design system: component libraries, interaction patterns, design tokens, and Figma implementation.
• Translate complex simulation and time-series data into intuitive visualizations (charts, scenario comparisons, dashboards).
• Collaborate cross-functionally with engineering, data science, product, and customer success to ensure designs are feasible and validated.
• Champion design quality through design reviews, usability testing, and stakeholder presentations.

Requirements

• 5–8 years of UX design experience with a portfolio demonstrating end-to-end product design, research, information architecture, interaction design, and visual design.
• Expert proficiency in Figma.
• Deep knowledge of UX heuristics and the ability to apply them to justify design decisions.
• Hands-on experience with AI design and coding tools (examples cited: Figma Make, Claude, GitHub Copilot, Lovable, or similar).
• Experience designing complex data visualizations for expert B2B users (dashboards, time-series, scenario comparison, simulation outputs).
• Experience designing AI-native product features (copilots, generative UI, recommendation systems) and designing for model uncertainty and trust.
• Strong skills in planning and conducting qualitative and quantitative user research and synthesizing findings into actionable designs.
• Proven experience building or maintaining component libraries and design systems in Figma (design tokens, variants, auto-layout, engineering handoff).

Preferred Qualifications

• Background designing cloud-native SaaS platforms for technical or domain-expert users.
• Front-end literacy: ability to read and write basic HTML, CSS, and JavaScript; comfortable collaborating closely with engineers.
• Exposure to energy market concepts is a plus.

What Great Looks Like

• Able to spin up an interactive prototype in an afternoon using tools like Figma Make or Claude to validate ideas quickly.
• Makes complex data legible without oversimplifying; strong opinions about AI UI anti-patterns and builds trustworthy AI assistance.
• Treats UX heuristics as a shared language to improve cross-functional design conversations.

Benefits / Working Model

• Flexible work location: work from home, in the office, or on the move; global, distributed team.
• Mission-driven product work with measurable impact on energy market planning and operations.
• AI-forward product culture and opportunity to work on PLEXOS Intelligence.
• Learning and growth: domain training (Energy Exemplar Xpert), conference attendance, and mentorship from product and engineering leaders.
