What is a UX/UI Designer at Johnson Controls?

As a UX/UI Designer at Johnson Controls, you will play a critical role in shaping the digital future of smart buildings, sustainability, and industrial automation. Unlike consumer-facing design roles, your focus will be on translating highly complex, technical data into intuitive, human-centered interfaces. You will work on software platforms like Johnson Controls OpenBlue, which integrates IoT (Internet of Things) data, AI, and physical hardware to optimize energy efficiency, building security, and indoor air quality.

Your designs will directly impact facility managers, building technicians, and enterprise operators who rely on real-time dashboards to make mission-critical decisions. This role sits at the intersection of physical infrastructure and digital innovation. To succeed, you must be comfortable designing for high data density, complex system architectures, and diverse user groups who operate in high-stakes environments.

This position offers a unique challenge: making the invisible visible. You will not just design clean layouts; you will map out complex workflows that connect physical hardware devices—such as HVAC sensors, security cameras, and smart thermostats—with cloud-based monitoring systems. It is an inspiring space where your design decisions contribute to reducing global carbon footprints and creating safer, smarter built environments.

Common Interview Questions

Preparing for the interview process requires a strong understanding of how your design decisions impact technical systems. Because Johnson Controls operates in the industrial and building automation space, interview questions will evaluate your system-level thinking, technical curiosity, and behavioral fit.

The following questions are representative of what you can expect, drawn from real interview experiences at the company.

Portfolio & Design Process

These questions evaluate how you approach complex design problems, validate your decisions, and structure your end-to-end design process.

Walk us through your favorite project in your portfolio. What was your specific contribution, and what was the ultimate business impact?

How do you approach designing interfaces that must display massive amounts of real-time data without overwhelming the user?
Can you describe a time when user research completely changed the direction of a design?
How do you maintain design consistency across a suite of legacy software applications and new digital platforms?
What is your process for creating user personas when your target audience is highly specialized, such as building engineers or facility technicians?

Technical & Hardware Integration

Because Johnson Controls designs software that interacts directly with physical systems, you may face technical questions that bridge the gap between digital UI and physical hardware.

How do you design digital workflows that correspond to physical actions, such as a technician repairing a physical HVAC unit?
Explain your understanding of how basic circuitry or hardware sensor inputs translate into digital data states in a user interface.
How do you handle latency or delayed feedback from physical devices in your user experience designs?
Describe your experience working with technical design systems and collaborating directly with front-end and embedded systems engineers.

Behavioral & Collaboration

These questions assess your communication style, how you handle stakeholders, and how you navigate cross-functional dynamics in a large enterprise.

Tell me about a time you had a strong disagreement with a product manager or lead engineer. How did you resolve it?
Describe a situation where you had to present a design concept to non-design stakeholders who did not understand UX principles.
How do you handle constructive criticism on a design that you spent a significant amount of time developing?
Tell me about a time you had to work under a tight deadline with incomplete user research. How did you prioritize your design decisions?

Deep Dive into Evaluation Areas

To pass the rigorous interview loops at Johnson Controls, you must perform exceptionally well across several core evaluation areas. Understanding these areas will help you tailor your portfolio presentation and behavioral stories.

Portfolio Presentation & System Design

This is the most critical technical round of the interview process. You will present your work to a panel of 5 to 6 designers and product leads, walking them through your design journey and explaining a key project in detail.

Be ready to go over:

Information Architecture – How you organize complex hierarchies of data and navigation.
Data Density Management – Your strategies for making highly dense data tables, charts, and dashboards legible and actionable.
Design System Utilization – How you leverage, contribute to, or build scalable design systems to maintain UI consistency.

Example scenarios:

"Walk us through a dashboard design where users had to monitor dozens of real-time data streams simultaneously."
"Show us a project where you had to redesign a legacy interface with significant technical debt."

Physical-Digital Integration & Technical Curiosity

Because Johnson Controls builds software for physical spaces, you must show an appreciation for how software interacts with hardware. You do not need to be an electrical engineer, but you should possess a basic curiosity about physical systems.

Be ready to go over:

Hardware constraints – Understanding how network latency, physical environment limitations, and device capabilities affect digital UI.
Basic circuitry and sensor concepts – Knowing how physical triggers (like a temperature sensor firing) map to UI states (like an alert banner).
Responsive and environmental design – Designing interfaces that might be viewed on mobile devices, rugged tablet screens in mechanical rooms, or giant wall monitors in a command center.

Example scenarios:

"How would you design an alert system for a building technician who is walking around a noisy mechanical room?"
"Explain how you would represent a malfunctioning physical valve in a digital schematic UI."

Cross-Functional Collaboration & Enterprise Navigation

Designing at a multi-billion-dollar company means working within established frameworks, aligning with engineering constraints, and managing diverse stakeholders.

Be ready to go over:

Developer handoff – How you document your designs, redlines, and transitions to ensure developers implement them accurately.
Handling pushback – Your approach when engineering says a proposed design is technically impossible to build within the current sprint.
User research in specialized fields – How you gather feedback when your users are highly specialized professionals rather than general consumers.

Example scenarios:

"Tell me about a time you had to compromise on a design to meet a critical product release deadline."
"How do you validate your design assumptions when you have limited direct access to the end-users?"

Key Responsibilities

As a UX/UI Designer at Johnson Controls, your daily work will directly influence the usability of enterprise-grade industrial software. You will be responsible for translating complex building automation requirements into seamless digital experiences.

Your primary responsibilities will include:

Designing intuitive user flows, wireframes, high-fidelity mockups, and interactive prototypes for web, mobile, and specialized hardware interfaces.
Collaborating closely with product managers to define user requirements, map out customer journeys, and translate business goals into design strategies.
Partnering with engineering teams to understand technical constraints, explain design intent, and ensure high-fidelity implementation of your UI designs.
Conducting user research, usability testing, and heuristic evaluations to continuously validate and iterate on your design solutions.
Contributing to and expanding the global Johnson Controls digital design system to ensure design consistency across all product lines.

You will typically work in an agile environment, collaborating daily with product owners, front-end developers, QA engineers, and industrial designers to bring complex smart-building features to life.
