Mask Design Engineer

In this role, you will have a fantastic opportunity to build deep expertise in mask engineering while developing strong mask design capabilities. You will start by gaining hands-on experience with mask data workflows, tooling environments, and tape-out processes, learning how cutting-edge photonic and semiconductor designs are translated into precision manufacturable mask data. As you grow, you will take on increasing responsibility in mask design activities. Key Responsibilities Own the end-to-end mask and reticle procurement process, including placing orders, managing workflows, and ensuring accurate and complete data submission to mask vendors. Drive fast, right-first-time ordering by translating design outputs into mask orders efficiently while maintaining a strong focus on accuracy and quality. Validate vendor outputs by reviewing digitised and fractured mask data to ensure design intent is fully preserved through the mask manufacturing process. Ensure fab readiness by confirming all delivered masks are compatible with production tools and meet required manufacturing specifications. Act as the technical interface between design teams, fabrication sites, and mask suppliers, proactively resolving issues and ensuring clear communication across all parties. Foster strong cross-functional collaboration across design, process, and manufacturing teams to ensure timely, aligned, and reliable mask delivery schedules. Once you have mastered the Mask engineering activities you will be given the opportunity to learn mask design and grow your confidence here. You will also support other development activities as required. Skills, Knowledge and Expertise Degree in Electrical Engineering, Physics, Materials Science, or related field. At least 2 + years industry experience in semiconductor or photonics environments, ideally within lithography, mask house, process integration or device engineering teams. Familiarity with EDA tools and design environments (e.g. layout viewers, mask data preparation tools, or verification tools). Understanding of design rules, lithography constraints, and manufacturability requirements. Strong attention to detail and commitment to high-quality output. Eagerness to learn and develop technical expertise in mask design. Proactive, hands-on problem solver with a structured approach to work. Ability to manage multiple tasks in a fast-paced development environment. Collaborative mindset with the ability to build strong working relationships. Comfortable working in an environment where precision and accuracy are critical. Advantage Good knowledge of device physics would be an advantage to support more complex designs in the future. Hands-on experience with mask data flow / tape-out processes (e.g. GDSII, OASIS, data verification, fracturing concepts). Knowledge of IIIV materials & previous mask design experience would also be an advantage.
