Contract - 12 Months

Location (mandatory): Redmond, WA Client is seeking a Prototyping Engineer to join our Advanced Development Team. The ideal candidate is a self-starter who thrives in ambiguity, takes initiative to identify gaps in systems and processes, and builds solutions from the ground up. They are naturally curious and fine tinkering with a number of components. 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 AR/VR devices. A portion of the role will also involve developing, maintaining, and refining AI workflows that improve efficiency and increase impact.

Job Responsibilities:

  • 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 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 AI model skills and recipes
  • Design, develop, and maintain multi-agent AI infrastructure and automated data pipelines.
  • Integrate AI agents with enterprise platforms using APIs and serverless platforms.
  • Collaborate with cross-functional teams (product, design, operations, infrastructure) to build innovative AI-native application experiences.
  • Build and integrate LLM / generative AI capabilities into product surfaces, including prompt engineering, structured prompting, and context management.
  • Troubleshoot display hardware and firmware/software issues.

Skills:

  • Hands-on hardware prototyping and systems integration experience with demonstrated ability to independently build and debug multi-disciplinary systems.
  • Bachelor's degree in Electrical Engineering, Mechanical Engineering, Systems Engineering, Physics, or equivalent practical experience.
  • Proficiency with electrical debugging tools (multimeter, oscilloscope, logic analyzer) and software debugging tools (ADB, serial consoles, log analysis).
  • Cross-disciplinary knowledge spanning mechanical, electrical, and software systems with ability to integrate subsystems and troubleshoot interface issues.
  • Experience with AR/VR display systems, optical alignment, or metrology.
  • Scripting/programming ability (Python, C/C++, shell) for test automation, data collection, or embedded systems work.
  • Experience with PCB rework, schematic reading, and firmware debugging environments.

Education/Experience:

  • 6+ years of hands-on experience in hardware prototyping, systems integration, or lab engineering, OR a relevant advanced degree + 3 years equivalent experience.
  • 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.
  • Experience with embedded systems debugging using tools such as ADB, UART/serial consoles, 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 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.
  • Experience with test/debug automation
  • Experience with latest AI tooling (eg: Claude, Codex, Gemini, etc.)
  • Hands-on experience with mechanical assembly, including torque-sensitive and precision-alignment operations.
  • Familiarity with firmware development environments, embedded Linux, or RTOS-based systems.
  • Experience building and maintaining lab infrastructure, test systems, or custom instrumentation.
