Intermediate Designer – Operator Experience

APPLY

At MacLean Engineering, we’re not just building machines — we’re redefining the future of mining through innovation. We’re seeking a additional Intermediate Designer to join our Operator Experience Team and help bring our next generation of operator interfaces to life on underground mobile equipment.

The Position:

This role focuses on the technical implementation of user interface designs. The successful candidate will work closely with UX/UI designers to translate approved interaction concepts and visual designs into real, fully functional, and high‑performance software running on mechatronic systems. If you enjoy turning polished designs into robust, production‑ready interfaces with a strong attention to detail, this role is for you.

Responsibilities and Duties

• Implement on‑machine HMIs using CODESYS Visualizations, ensuring high fidelity to UI/UXspecifications.
• Develop HMI middleware that interfaces with the machine control system via CAN (e.g., J1939/CANopen) and Ethernet, including data handling, messaging, and state management
• Contribute to our architecture migration toward an OPC UA–based stack
• Maintain legacy remote-control operator station software (PySide,tkinter)
• Develop modern user interfaces using QML and C++
• Collaborate daily with software, controls, and systems engineering from other teams to ensure technical feasibility, reliability, and alignment with platform constraints.
• Work within an agile framework; contribute to planning, estimation, and demos with Product Management; deliver incrementally.

First Year Goals:

• Help deliver a first production slice of the OPC UAGUIarchitecturefor ourGR8 machine.
• Contribute to a sharedcomponentlibrary that can be reused across on‑machine and off‑machine GUIs.
• Contribute to the evolution of Operator Experience design standards and best practices.

Qualifications:  The ideal candidate will demonstrate strong problem-solving skills, attention to detail, and the ability to collaborate in a multidisciplinary environment. They will show initiative, adaptability, and a desire to continuously improve their craft. Additionally, they should meet the following qualifications:

• 3–5 years of experience building production UI for complex systems (industrial, automotive, robotics, embedded, or similar)
• Strong communicationskills, with the ability to clearly articulate design rationale in English
• Strong implementation skills with at least one of:
  • Qt/QML for UI development
  • C++ for application logic / integrations
  • CODESYS Visualization (or similar industrial HMI platform)
• Experience integrating with machine/data interfaces (e.g., CAN, J1939/CANopen, Ethernet, or similar)
• Proven ability to match design intent (layouts, states, transitions, behaviors) from tools like Figma, and to collaborate effectively with UI/UXdesigners
• Solid software engineering fundamentals: version control (Git), code reviews, debugging, and performance-minded development

The following are considered assets:

• Hands‑on experience with OPC UA (server and/or client), data modeling, subscriptions, and binding to UI.
• Experience withPySideortkinter
• Familiarity with deploying software to systems running Linux
• Experience in industrial design using CAD
• Exposure to mining, heavy equipment, or mobile machinery environments
• Proficiencyin French/Spanish
• Degree or diploma in software engineering, computer engineering, mechatronics,or related (or equivalent practical experience)
