Senior AI​/HMI Developer

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.

• 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.

• Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or a related field.
• 5+ years of experience in software development, including experience building user‑facing applications.
• Experience developing AI-enabled applications, preferably assistant, search, or RAG-style systems. LLM deployment and optimization/inference.
• Experience building frontend or HMI applications for device, industrial, automotive, or embedded environments.
• Experience integrating applications with backend services, APIs, or device‑side data sources.
• Familiarity with prompt design, grounding strategies, response guardrails, and assistant behavior design.
• Experience with automated testing and software quality practices.
• Strong problem‑solving, communication, and cross‑functional collaboration skills.

• Experience with voice‑enabled systems, including ASR, TTS, or multimodal interaction workflows.
• Experience building applications for secondary displays, in‑vehicle systems, industrial HMIs, or operator‑facing products.
• Familiarity with machine, vehicle, or industrial data integration.
• Experience in heavy equipment, automotive, industrial IoT, robotics, or connected machinery.
• Experience with offline/degraded mode design and performance-sensitive edge applications.
• Familiarity with logging, diagnostics, OTA-connected products, or field‑deployed systems.
• Experience working with technical documentation, service content, fault codes, or similar grounded knowledge sources.
