Research and Development Scientist - Semiconductor Laser Design / Modeling Engineer

About our group:

Seagate products help more people store, share, and protect their valuable digital content. With 97% of the world’s information being stored on hard drives, the rapid growth of digital data makes Seagate more important every day.

Seagate is where the future is read and written, with continuous innovation proving that a hard drive is not “Seagate-40 years of Data Storage Innovation". Find out how we are shaping a new era of storage as we craft the datasphere.

As an industry leader, Seagate provides unique career opportunities to be part of today’s major technology shifts. They can be found around the globe and on our website.

The Seagate Derry / Londonderry Manufacturing site has been open for 30 years this year. We have over 1750 people working in our facility which is among the most advanced in the world, in the design, development, and volume manufacturing of recording heads. These recording heads write information onto and read information from the recording disc, within the data storage device.

In the role of Laser Design Modeling Engineer, you will be working within the Advanced Technology Research and Development team. This team is part of the broader Recording Head Organisation. Partnering with the worldwide wafer development and test / characterization teams our responsibility is to develop and the recording heads for future generations of Hard Disk drives.

About the role - you will:

• Carry out computational modelling and design of advanced semiconductor laser architectures for next generation Mozaic 4+ (HAMR) read-write heads.
• Use LaserMOD/Crosslight/Harold etc, FDTD, Lumerical Interconnect and other similar methods to simulate laser performance within the HAMR integrated photonic system.
• Carry out data analysis to support modelling conclusions, making closure assessments and recommending improvements.
• Work with R&D engineers and scientists to plan experimental builds and testing of the proposed designs.
• Improving existing modelling capabilities and development of new modelling methodologies.
• Collaborate with adjacent teams and internal customers to ensure that the proposed future designs will meet the performance and reliability requirements of the future product roadmap.
• Keep abreast of developments in the field of III V semiconductor laser research.
• Collaborate with external research partners to translate emerging laser, photonics, and materials research into practical technology options.
