Web GUI Engineer - Salt Lake City, UT

The Position

We are seeking a Web GUI Engineer to design and develop advanced, highly interactive user interfaces for our commercial audio, amplification, and security products.

This is not a traditional web development role. Our interfaces are embedded web GUIs served directly from hardware devices such as DSP processors, amplifiers, and control systems. These interfaces visualize and control real-time systems, including audio processing (EQ, compression), system configuration, and live device monitoring.

This position will work on a small, focused project team alongside firmware engineers, a fellow GUI developer, and a product manager to create intuitive, high-performance control interfaces used by professional integrators around the world.

This role is on-site, 5 days a week. Remote option is not available.

We are looking for qualified candidates in the Salt Lake City, UT market.

Essential Functions

• Design and develop rich, real-time web-based GUIs using Angular.
• Build highly interactive interfaces including: Audio EQ graphs, meters, and signal visualization; dynamic control panels for DSP, amplifiers, and system routing; real-time monitoring dashboards using live data streams.
• Integrate with device firmware via WebSockets (primary interface for real-time communication).
• Collaborate closely with Firmware engineers providing device APIs, Product Managers defining features and workflows, and UX designers shaping overall user experience.
• Create and maintain reusable UI components and libraries.
• Optimize UI performance for real-time responsiveness and constrained hardware environments.
• Act as a subject matter expert in frontend technologies, recommending tools, frameworks, and improvements to elevate interface quality.
• Stay current with modern frontend development trends, best practices, and security requirements.

• Familiarity with Real-time data handling (e.g., WebSockets), component-based architecture, and reusable UI systems
• Strong understanding of UI performance and responsiveness
• Experience working with Git and collaborative development workflows
• Able to work cross-functionally with engineering and product teams

Skills

• Experience with PrimeNG
• Experience with data visualization libraries (e.g., charts, graphs, meters)
• Familiarity with MQTT or device communication protocols
• Experience building interfaces for device control or industrial systems

Other Requirements

• Contribute to UI architecture and design decisions
