About our group:
From the videos, music and documents we share with friends and family on social networks, to the servers that form the backbone of enterprise data centres and cloud-based computing, Seagate products help people store, share and protect their valuable digital content. As an industry leader, Seagate provides unique career opportunities to be part of today’s major technology shifts.
Seagate’s Springtown facility in Derry/Londonderry, Northern Ireland is among the most advanced in the world in the design, development and volume manufacturing of recording heads.
About the role - you will:
We are seeking highly motivated Material Scientists / Material Engineers to join our Process Engineering team supporting recording-head wafer manufacturing. This is a rare opportunity to work at the forefront of photonic and advanced materials, thin-film engineering, plasma processing and nanoscale device fabrication. You will work on the development, optimisation, characterisation and sustaining of photonic materials and associated wafer processes for Heat-Assisted Magnetic Recording (HAMR) heads, helping to enable next-generation magnetic recording technologies.
We strongly encourage applications from recent PhD graduates, as well as experienced scientists and engineers looking to expand their expertise in a fast-moving, high-technology environment.
You Will:
• Develop, optimise and characterise photonic materials and thin-film processes used in HAMR recording-head wafer fabrication.
• Investigate the optical, physical, chemical and structural properties of photonic materials, and relate these properties to device and process performance.
• Develop, optimise and characterise other thin-film materials used in recording-head fabrication, including metals, dielectrics, magnetic alloys and barrier layers.
• Drive improvements in film structure, composition, stress, uniformity and functional properties through rigorous experimentation and analysis.
• Support advanced wafer-process modules such as sputter deposition, ALD, PECVD, etch, CMP, annealing and metrology.
• Apply principles of materials science, physics and chemistry to diagnose material-related defects, yield excursions and process instabilities.
• Collaborate with cross-functional teams, including Equipment Engineering, Integration, Metrology, Product Engineering and R&D, to accelerate process maturity and technology readiness.
• Implement statistical and data-driven methodologies, including DoE, SPC, FDC and data modelling, to ensure process robustness and stability.
• Document and communicate results through technical reports, presentations and cross-site collaboration.
About you:
• Strong experimental-design and problem-solving capabilities. What We Offer
• Excellent analytical skills, with an ability to interpret complex materials, optical and process data.
• A strong understanding of composition-structure-property-performance relationships in thin films and photonic materials.
• Curiosity, creativity and a proactive approach to learning.
• Strong written and verbal communication, and the ability to work effectively in cross-functional teams.
• Ability to work in a dynamic, high-volume manufacturing environment.
• Opportunity to work on photonic materials and state-of-the-art wafer manufacturing technology for HAMR recording heads.
• Close collaboration with leading engineers and scientists.
• Mentorship for early-career PhD graduates.
• Clear development pathways into technical leadership.
