The ideal candidate is detail-oriented, comfortable working with delicate components, and interested in supporting the development of advanced photonic computing hardware.

• Perform hands-on assembly, packaging, and final-stage processing of PCBs and silicon photonic chips. Including but not limited to conducting PCB assembly, soldering, wiring, and troubleshooting activities.
• Perform wire bonding for PCBs and chips. Experience preferred but not required.
• Design mechanical components, fixtures, and enclosures using CAD software.
• Assemble and modify mechanical parts and laboratory test fixtures.
• Coordinate with vendors.
• Conduct initial electrical and optical testing of components, assemblies, and devices.
• Operate, maintain, and organize optical, electrical, and mechanical laboratory equipment.
• Record test procedures, measurement results, observations, and assembly information accurately.
• Analyze test data and prepare plots, reports, and technical documentation.
• Collaborate with project managers, test engineers, and other team members to complete project objectives efficiently.
• Maintain a clean, organized, and safe laboratory workspace.
• Willing to learn new things.

• Bachelor’s degree or at least two years of post-secondary education in Optical Engineering, Mechanical Engineering, Electrical Engineering, Applied Physics, or a related technical field.

• At least one year of relevant professional, academic laboratory, internship, or project experience.
• Hands-on experience with electrical or optical test equipment.
• Experience working in an electronics, optics, semiconductor, manufacturing, or research laboratory environment is preferred.

• Proficiency with CAD software, such as Autodesk Fusion.
• Experience with mechanical design and assembly.
• Familiarity with PCB assembly, soldering, or rework.
• Familiarity with common electrical test equipment, such as oscilloscopes, multimeters, power supplies, and signal generators.
• Familiarity with optical laboratory equipment and fiber-optic components is a plus.
• Ability to prepare engineering reports, analyze data, and create clear technical plots.
• Strong written and verbal communication skills.
• Attention to detail and ability to work carefully with small, fragile components.
• Ability to work independently while contributing effectively in a team-oriented environment.
• Previous experience in a similar role is preferred.

• Work is primarily performed in an engineering laboratory and office environment.
• Regular use of computers, laboratory equipment, hand tools, and other office equipment is required.

• Ability to stand at a laboratory workstation for extended periods.
• Ability to occasionally lift and carry equipment or materials weighing up to 40 pounds.
