Lead Design Engineer
About the Role
The world’s communications infrastructure depends on semiconductor lasers, particularly those based on indium phosphide (InP) technology. InP lasers are engineered to emit at wavelengths optimal for long-distance transmission through fiber optics, enabling the optical networks that form the global internet. Coherent’s broad portfolio of InP components includes application-specific Fabry-Pérot lasers, directly modulated lasers (DMLs), tunable lasers, photodiodes for high-speed receivers, and power monitoring. In 2022, we introduced 200 Gbps InP electro-absorption modulated lasers (EMLs) for high-speed datacenter transceivers, providing advanced, robust, and cost-competitive devices for 800G and next-gen 1.6T datacom transceiver designs. Our proven InP technology platform is one of the few in the industry with over one hundred million lasers deployed in the field.
We are seeking a Lead Engineer to drive the design and development of high-power InP-based semiconductor lasers for high-speed data communication applications. This role requires technical leadership, hands-on device development, and cross-functional coordination across internal teams and external partners. It offers the opportunity to be at the forefront of high-power laser innovation in a fast-paced, results-driven environment.
