Job description

Application Engineer – Vinci4D.ai

Join to apply for the Application Engineer role at Vinci4D.ai

We are building an AI assistant for hardware design. Our product helps engineers explore, analyze, and optimize hardware systems, integrating cutting‑edge AI with the realities of engineering design workflows.

Role Overview

We are seeking an Application Engineer who will work directly with customers to run and validate their test cases through our product. You’ll act as a bridge between our technology and our users, ensuring that customer needs are understood, test cases are well‑executed, and results are actionable. Additionally, you will help customers with questions about how to use our software and also provide training on using new features.

You’ll collaborate closely with our customers, as well as our product and engineering teams to help customers evaluate and deploy AI‑assisted workflows. A strong foundation in hardware design is essential, and experience with thermal problems (thermal analysis, heat transfer, cooling strategies) is highly preferred.

Responsibilities

• Work directly with customers to run their design test cases through our AI assistant.
• Collaborate with customers’ hardware engineers to interpret results, provide insights, and recommend workflows.
• Document use cases, best practices, and lessons learned for internal and customer‑facing knowledge bases.
• Provide feedback to the product and engineering teams to improve features, accuracy, and user experience.
• Support customer onboarding, training, and integration of the AI assistant into existing design processes.

Qualifications

Required

• Degree in Mechanical, Electrical, or Computer Engineering, or related technical discipline.
• 3+ years experience working in hardware design, simulation, or engineering workflows.
• Strong ability to communicate technical results clearly to both engineers and non‑technical stakeholders.
• Hands‑on experience with engineering tools (CAD, simulation software, etc.).

Preferred

• Background in thermal problems (e.g., heat transfer, cooling strategies, thermal analysis).
• Experience working in customer‑facing roles (applications engineering, solutions engineering, field engineering, or technical consulting).
• Strong problem‑solving mindset and ability to quickly learn new tools and workflows.

Why Join Us

• Be part of a team defining the future of AI in hardware design.
• Work at the intersection of advanced AI, real‑world engineering, and customer success.
• Collaborate with world‑class engineers and researchers in a fast‑moving startup environment.
