Prototyping Engineer IV

About the role

• This role requires a versatile engineer with a working understanding of mechanical, electrical, and software systems who can smoothly integrate various subsystems into functional prototypes.
• The position involves hands‑on building, working together with AI tools, debugging, and iterating on prototype hardware systems for next‑generation Augmented Reality / Virtual Reality (AR/VR) devices.
• A portion of the role will also involve developing, maintaining, and refining AI workflows that improve efficiency and increase impact.

• Independently identify technical gaps and take initiative to design, build, and integrate multi‑disciplinary prototype systems spanning mechanical, electrical, and software domains.
• Integrate and validate subsystems (optical, electrical, mechanical, firmware) into cohesive prototype assemblies, ensuring proper communication and functionality across interfaces.
• Debug hardware and firmware issues using lab instrumentation including multimeters, oscilloscopes, logic analyzers, and power supplies to isolate root causes at the electrical level.
• Perform software‑level debugging through tools such as adb, serial consoles, and log analysis to troubleshoot embedded systems and device firmware.
• Develop Graphical User Interfaces (GUIs) and streamline bring‑up processes with AI practices.
• Develop and maintain test fixtures, jigs, and custom tooling to support prototype builds, alignment, and validation.
• Collaborate cross‑functionally with optical, mechanical, electrical, and software engineers to translate research concepts into working prototype hardware.
• Develop and document assembly processes, integration procedures, and debug workflows to enable repeatable prototype builds.
• Proactively identify risks and propose solutions during prototype bring‑up, driving issues to resolution with minimal oversight.
• Support AR display system hardware integration and process development, including optical alignment, metrology, and functional testing.
• Leverage AI methods for data analysis, data visualization, and process development.
• Develop Artificial Intelligence (AI) model skills and recipes.
• Design, develop, and maintain multi‑agent AI infrastructure and automated data pipelines.
• Integrate AI agents with enterprise platforms using Application Programming Interfaces (APIs) and serverless platforms.
• Collaborate with cross‑functional teams (product, design, operations, infrastructure) to build innovative AI‑native application experiences.
• Build and integrate Large Language Model (LLM) / generative AI capabilities into product surfaces, including prompt engineering, structured prompting, and context management.
• Troubleshoot display hardware and firmware/software issues.

• 8+ years of hands‑on experience in hardware prototyping, systems integration, or lab engineering.
• Demonstrated ability to work as a self‑starter: identifying problems, proposing solutions, and driving projects forward with minimal direction.
• Working knowledge across multiple engineering disciplines (mechanical, electrical, and software) with the ability to understand how subsystems interact.
• Proficiency with electrical debug tools including multimeters, oscilloscopes, and logic analyzers for signal integrity and power analysis (SI/PI).
• Experience with embedded systems debugging using tools such as Android Debug Bridge (adb), Universal Asynchronous Receiver‑Transmitter (UART)/serial consoles, Joint Test Action Group (JTAG), or similar interfaces.
• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Systems Engineering, Aerospace Engineering, Physics, or equivalent practical experience.
• Experience collaborating cross‑functionally with hardware, firmware, and software teams to deliver integrated prototype systems.

• Experience with AR/VR or display system prototyping, including optical alignment and metrology.
• Familiarity with Printed Circuit Board (PCB) design review, schematic reading, and basic soldering/rework for prototype modification.
• Experience with scripting or automation (Python, shell scripting) to support test, data collection, or process automation.
