At ThingsBoard, design is about creating clear product experiences for users who work with data, devices, and automation.

Users configure devices, build logic, monitor real-time data, and make operational decisions.

Your role is to make these workflows clear, usable, and powerful.

We’re looking for a Lead UI/UX Designer who wants ownership, works closely with Product and Engineering, and helps strengthen design inside ThingsBoard.

What you’ll be responsible for

• Designing data-heavy interfaces:
  • dashboards;
  • analytics;
  • monitoring systems.
• Simplifying complex system logic into:
  • clear user flows;
  • understandable UI states;
  • predictable interactions.
• Working on configuration-heavy features:
  • rule chains;
  • automation logic;
  • device setup flows.
• Driving design decisions together with Product & Engineering.
• Building, maintaining, and scaling a design system for both designers and developers.

• Improving existing design processes within the team.

What we expect from your experience

• A strong portfolio demonstrating a thoughtful approach to solving design challenges.
• Proven experience building, implementing, and scaling complex design systems from scratch.
• Ability to work closely with developers and a solid understanding of technical constraints.

• Experience establishing and evolving design processes within a team.
• Experience in hiring, onboarding, mentoring, and growing designers.
• Proven track record of managing a design team.

• Experience working with product metrics
• Experience conducting user research and usability testing to drive product improvements
• Familiarity with Material Design 2 and an understanding of Angular

Why is this role interesting?

• Real complex product, not marketing UI
• Direct impact on how users understand and act on data
• High ownership: you influence product decisions, not just UI

• Work closely with strong engineering team on system-level problems

What we offer

• Competitive and transparent compensation based on your experience and impact.
• Meaningful product challenges and clear ownership.
• Close collaboration with Product and Engineering.
• Supportive team environment with clear goals and feedback.
