Overview

We are seeking a Senior AI Application / HMI Developer to build the user-facing and assistant-intelligence components of an aftermarket In-Cab AI Assistant platform for heavy equipment. The solution includes voice-first interaction, a secondary display, grounded Q&A, guided navigation of existing machine functions, and connected-device capabilities such as OTA updates, logging, and diagnostics. This role focuses on assistant behavior, content grounding, UI/HMI implementation, and integration of voice and visual workflows within defined safety and system boundaries.

Responsibilities

· Design, develop, and maintain the assistant application and HMI components for the in-cab platform.

· Implement grounded Q&A and guided workflows using approved content sources and defined guardrails.

· Build user-facing experiences for the secondary display, including visual support for voice-first interactions.

· Integrate assistant logic with machine-scoped data, diagnostics, and existing machine navigation flows.

· Support integration of voice, audio, and multimodal interaction patterns.

· Contribute to assistant quality, response behavior, error handling, and degraded/offline user experiences.

· Develop automated tests and support integration, system, and validation activities.

· Collaborate with the Architect, embedded developers, QA, and TPM to deliver working software increments and release-ready builds.
