UI​/UX Design Engineer

Summary:

Mujin is the future of industrial robotic systems in production and distribution environments. Our technology gives robots perception and awareness, enabling them to take on more advanced tasks. We aim to revolutionize the use of robotics within industry to free human resources from labor-intensive tasks to focus on more intellectual challenges.

We're looking for a UI/UX Design Engineer — a designer who ships. In this role you'll create and build the interfaces people use to run intelligent robot systems on a live factory floor, across our operator's HMI touchscreens and PC control applications. Everything a human knows about what a robot is doing flows through the UI you design and code. Our goal is to make intelligent robots usable by anyone, with no custom development or training required.

What you'll do:

• Own features end to end — in Figma and in code. You will design the solution and ship the production front end for it in our MUI/React codebase, rather than handing a spec to someone else to interpret.
• Collaborate across teams, not just within design. Work day-to-day with product, engineering, and subject‑matter experts, and directly with the operators, integrators, and field teams who live with these robots — to turn real user needs and business goals into logical and intuitive experiences.
• Design human–machine interactions across multiple surfaces: PC desktop apps (data‑dense job queues, dashboards, integrator tooling), operator HMI touchscreens (gloved‑hand, high‑contrast, real‑time robot and job status) and operator scanner screens.
• Design the unhappy paths as carefully as the happy one. Model complex, safety‑relevant states — loading, degraded, faulted, recovering — so operators always know what the robot is doing and what is needed for continuous operations flow.
• Prototype fast to learn fast. Produce multiple concepts, test them, and know when to go deeper versus when to pivot.
• Contribute to and extend the Mujin Controller design system and MUI theme so the whole team ships a cohesive, high‑craft experience.
• Ground your decisions in real‑world user data, scenarios, and context. Partner with engineers and subject‑matter experts, engage commercial and operations stakeholders, review field footage and support signals, and defend design choices with evidence, not preference.

Position Requirements:

• 3+ years designing complex enterprise or industrial product UI (native or web), with a portfolio showing production‑released, visually refined work — and the reasoning behind each choice.
• Verifiable implementations of your designs into production. MUI experience is a strong plus.
• Product taste and product thinking. Evidence you shaped what got built, not only how it looked but also how it worked — showing you prioritize ruthlessly and tie design to outcomes (adoption, error rate, task time).
• Logical, systems‑level thinking. You reason through state, edge cases, and data density the way an engineer does — the core of good experience design work.
• Communication fluency. You speak and write confidently about your design decisions, argue them without ego, and collaborate fluently in English with a distributed engineering team.
• AI‑native workflow. You already use AI design/coding tools (Claude Code, Cursor, and similar) to build and prototype faster.
• You take initiative. You don't wait to be handed a spec — you spot gaps, raise problems early, propose better ways of working, and push craft and process forward for the whole team.

Preferred backgrounds:

Design engineers from technical‑product or dev‑tools companies; product designers from complex B2B/enterprise or ops tooling who ship their own front‑end; or UX designers from industrial, robotics, automotive, medical‑device, or other real‑time / safety‑critical domains.
