• Laser Alignment & Testing: Perform hands-on alignment, calibration, and characterization of laser diodes, optical systems, and microoptics within the lab environment.
• Laboratory Work: Operate and maintain lab equipment such as spectrometers, optical power meters, lasers, and other measurement tools, ensuring precision and accuracy in experiments.
• Optical Design: Assist in the design and optimization of optical systems for laser diode applications, including microoptics, lenses, beam-shaping elements, and alignment systems.
• Development of Workstations: Contribute to the development and improvement of optical alignment workstations, incorporating both hardware and software to enhance productivity and precision.
• Hands-On Experimentation: Work closely with senior scientists and engineers to design experiments, analyze data, and identify opportunities for improvement in laser performance and packaging.
• Microtechnology & Microoptics: Work with microtechnology and microoptics components, helping to integrate them into laser systems and ensuring optimal functionality.
• LabVIEW & Automation: Utilize LabVIEW or similar software to develop automated test systems for monitoring and controlling experiments, capturing data, and generating reports.
• Product Development: As you gain expertise, you will gradually take on product ownership responsibilities, ensuring that all technical aspects of the product meet performance standards, timelines, and cost targets.
• Collaboration: Work alongside a cross-functional team of physicists, engineers, and product managers to optimize product performance, share insights, and contribute to product development.
• Documentation & Reporting: Maintain accurate experimental records and provide detailed reports on lab work, experimental results, and improvements for ongoing projects.
• Continuous Learning: Stay current with advancements in laser physics, microoptics, and optical design technologies through research, training, and collaboration with senior team members.

Qualifications:

• Education: Bachelor’s or Master’s degree in Physics, Optical Engineering, or a related field. A strong foundation in laser physics and optical systems is essential.
• Laboratory Skills: Experience working in a laboratory environment, including alignment, calibration, and testing of optical systems, lasers, and related equipment.
• Software Skills: Proficiency in LabVIEW or similar programming environments for developing automated testing systems and controlling lab equipment.
• Optical Design Knowledge: Understanding optical design principles, including beam shaping, lens systems, and microoptics. Experience with optical simulation tools (e.g., Zemax, COMSOL) is a plus.
• Mechanical Design: Basic knowledge of mechanical design principles, particularly in the context of optical alignment and integration. Familiarity with ceramics and their use in laser and optical systems is an advantage.
• Attention to Detail: Strong ability to troubleshoot and analyze experimental results, paying close attention to the smallest details to ensure precision and accuracy.
• Communication Skills: Good written and verbal communication skills to document experiments, present findings, and work with cross-functional teams.
• Motivation & Initiative: Eagerness to learn and contribute to innovative projects, with a strong interest in laser technologies and optical systems.
• Team Player: Ability to work effectively both independently and as part of a collaborative team.

Preferred Qualifications:

• Experience with optical alignment workstations and automated testing setups.
• Familiarity with microtechnology or microoptics applications in laser systems.
• Understanding mechanical design software (e.g., SolidWorks, AutoCAD) to assist with alignment system design.
• Prior experience working in an R&D environmen or with laser diodes, microoptical components, or photonics.
• Familiarity with ceramics and their role in optical systems or laser packaging.

Why Join Us?
