Participate in optical performance testing and analysis (e.g., insertion loss, return loss, optical power, wavelength performance).
Help document test results, prepare technical reports, and contribute to design reviews.
Collaborate with cross-functional teams (mechanical, electrical, firmware) to support product development.
Maintain lab equipment and ensure proper usage and calibration where required.

Qualifications

Bachelor’s or Master’s student in Optics, Photonics, Optical Engineering, Physics, or related fields.
Basic understanding of optical principles (e.g., geometrical optics, fiber optics, wave optics).
Familiarity with optical testing equipment (e.g., optical power meter, oscilloscope, OSA) is a plus.
Experience with optical simulation tools (e.g., Zemax, LightTools, or equivalent) is preferred.
Strong analytical thinking and problem-solving skills.
Good communication skills and a collaborative mindset.
Proficiency in English reading/writing for technical documentation.

Preferred Qualifications

Exposure to optical communication systems (e.g., DWDM/WDM, transceivers, modules).
Basic programming skills (Python, MATLAB, or similar) for data analysis.
Internship or project experience in optics/photonics is a plus.

What You’ll Gain

Hands-on experience in real-world optical product development.
Mentorship from experienced optical engineers.
Exposure to cutting-edge optical communication technologies.
Opportunity to convert to a full-time role based on performance.

About the Company

Koch Industries

Private conglomerate in energy and materials

Koch Industries is a large, private, diversified conglomerate that operates in energy, chemical processing, and manufacturing. It started from an innovation that turned heavy crude oil into gasoline and grew through long‑term investments rather than short‑term market moves. The company generates value by refining fuels and producing chemical products, and it operates Georgia-Pacific, a major maker of paper and building products. Its business model relies on reinvesting most earnings back into the company to fund steady, long‑term growth rather than paying out frequent dividends or seeking quick profits. Koch differentiates itself from many competitors by staying privately owned, which reduces pressure from public markets and enables longer‑range planning. The company’s goal is to build scale and durability across its holdings by sustainable, multi‑decade growth rather than rapid, episodic gains.
