We're a fast-moving technology company focused on bringing to market innovative solutions that solve complex engineering problems. You'll be part of a highly accomplished team with excellent professional development and upside potential.

JOB DESCRIPTION

We are seeking a highly motivated and experienced Silicon photonic design engineer to join our team developing next-generation optical interconnects for AI and data center applications. You will design, simulate, and validate photonic devices and circuits. This role combines technical depth with cross-functional collaboration.

This role necessitates a hands-on approach in designing photonics IC which includes schematic capture, layout and validating device in the lab. The successful candidate will be responsible for taking products from the initial concept phase through production.

Responsibilities include

• Design, layout and optimize photonic devices (lasers, modulators, detectors, waveguides).

• Perform simulations using industry-standard tools (Lumerical, Synopsys, COMSOL).

• Collaborate with packaging, electronics, and firmware teams to ensure system-level integration.

• Support prototype development, testing, and bring-up of photonic integrated circuits (PICs).

• Document design methodologies and contribute to IP development.

THE IDEAL CANDIDATE SHOULD DEMONSTRATE THE FOLLOWING BEHAVIORAL TRAITS:

• Proven leadership and mentoring skills

• Excellent problem-solving skills

• Ability to work independently as well as within a dynamic team environment

• Strong multi-tasking and project management ability

• Strong written and verbal communication skills

MINIMUM QUALIFICATIONS:

• MS/PhD in Electrical Engineering, Physics, Optics, or related field.

• Hands-on experience with PIC design and layout.

• Strong background in optical device physics and semiconductor fabrication.

• Familiarity with scripting/programming (Python, MATLAB, C++).

Compensation will be competitive.
