UI/UX Design Engineer

Mujin•Suwanee, GA

About The Position

Mujin is developing intelligent robotic systems for production and distribution environments, giving robots perception and awareness to handle advanced tasks. The company aims to revolutionize robotics in industry, freeing human resources for more intellectual challenges. This role is for a UI/UX Design Engineer who will create and build interfaces for running intelligent robot systems on a factory floor, including operator HMI touchscreens and PC control applications. The UI designed and coded will be the sole source of information for humans regarding robot operations. The goal is to make intelligent robots usable by anyone without custom development or training. In this role, you will own features end-to-end, designing solutions and shipping the production front-end in the MUI/React codebase. You will collaborate across teams, including product, engineering, subject-matter experts, operators, integrators, and field teams, to translate user needs and business goals into intuitive experiences. You will 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 status), and operator scanner screens. Designing for unhappy paths, including complex safety-relevant states like loading, degraded, faulted, and recovering, is crucial to ensure operators always understand robot status and operational needs. Rapid prototyping is encouraged for fast learning, with the ability to produce multiple concepts, test them, and decide when to deepen or pivot. You will contribute to and extend the MujinController design system and MUI theme for a cohesive, high-craft user experience. Design decisions must be grounded in real-world user data, scenarios, and context, with collaboration with engineers and subject-matter experts, engagement with stakeholders, and review of field data to support design choices with evidence.

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.
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.

Nice To Haves

MUI experience is a strong plus.
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.

Responsibilities

Own features end to end — in Figma and in code.
Design the solution and ship the production front end for it in our MUI/React codebase.
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 MujinController 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.
