Senior Epitaxy Engineer

About Wolveshill Consulting

Wolveshill Consulting (WHC) designs and delivers industrial, semiconductor and connected hardware systems for clients across fleet, manufacturing, smart infrastructure and communications industries.

Our work spans connected systems, IoT and telematics platforms, semiconductor technologies, industrial automation and communications hardware. We support clients through technical consulting, design support and practical project delivery across complex engineering and cross-border technology projects.

As part of our expanding work in semiconductor and communications hardware, WHC is strengthening its focus on photonic technologies, optical modules and III-V compound semiconductor applications for telecoms, datacom, data centres and advanced computing infrastructure. We are now seeking an experienced Senior Epitaxy Engineer to support the development of advanced III-V semiconductor technologies for high-performance optical and electronic applications.

The Role

We are seeking a Senior Epitaxy Engineer to act as the technical bridge between our internal design teams and external foundry partners in Europe and China. This is a unique hybrid role for a hands-on expert in III-V compound semiconductor epitaxy who can oversee and troubleshoot the entire epitaxial process flow for advanced photonic devices.

Working from the UK, you will travel to oversee critical process development, qualification, and production ramp at foundry partners. You will serve as the primary technical authority for epitaxial growth, ensuring that external manufacturing meets the stringent performance and reliability requirements of next-generation optical communications products.

What You'll Do

• Serve as the primary technical liaison for all epitaxy activities at foundries in Europe and China.
• Lead day-to-day epitaxy operations, including process planning, recipe optimization, growth execution, and materials characterization using tools such as XRD, PL, CL, EL, SEM, AFM, and surface defectivity assessments

Knowledge, Skills & Abilities

• Significant practical experience with MOCVD systems, epitaxial growth processes, and materials characterization
• Good understanding of equipment design, preventive maintenance, and scrubber systems, as well as analytical tools such as XRD, PL, CL, EL, SEM, and AFM
• Strong technical foundation in R&D process development and advanced manufacturing environments (e.g., III–V semiconductors, high-speed optical communications)
• Ability to interpret complex experimental data, troubleshoot process issues, and drive systematic improvements
• Excellent teamwork, documentation, and communication skills

Minimum Qualifications

• Bachelor’s degree in Materials Science, Physics, Electrical Engineering, Chemistry, or a related field
• Extensive experience with hands-on epitaxy R&D, semiconductor process engineering, or advanced manufacturing environments
• Proven track record of designing complex DOEs and executing structured experiments in MOCVD systems or related thin-film deposition technologies
• Experience in failure analysis, defect classification, and quality management techniques/tools.
• Experience in photonics applications.

Preferred Qualifications

• PhD or Master’s degree in a related technical discipline
• Background in telecommunications-grade or high-reliability laser product development.
• Experience supporting advanced photonics or optical communication applications
• Experience working with III–V semiconductor technologies in R&D or high-volume manufacturing involving III–V materials
• Proven track record in mass production process development, yield improvement, and throughput optimization
• Awareness of global technology trends and the competitive landscape within III-V semiconductors and photonics.
• Proficiency in Manderin Chinese for collaboration with China-based foundries and internal teams.

Working Environment

This role operates within a hybrid working model, combining remote working with regular onsite activity at semiconductor manufacturing and R&D facilities.

The position will involve international travel to foundry and technology partners across Europe and China to support process development, project collaboration, manufacturing activities, and technical reviews.

Candidates should be comfortable working within cleanroom and semiconductor laboratory environments, as well as highly technical R&D and manufacturing settings with strict process and safety protocols.

Why Wolveshill Consulting?

• Your epitaxial expertise will directly influence the success of products addressing the multi-billion-dollar optical component market.
• Enjoy a hybrid working model based in the UK with significant autonomy, combined with the excitement of international travel to world-class fabrication facilities.
• Join a multidisciplinary engineering environment spanning photonics, industrial systems, and next-generation communications, as well as collaboration with international engineering and technology partners.

Diversity & Inclusion

Wolveshill Consulting is committed to building an inclusive and diverse workplace. We welcome applications from candidates of all backgrounds and are dedicated to creating an environment where innovation, collaboration, and technical excellence can thrive.

Reasonable accommodations are available for candidates requiring additional support throughout the recruitment process.
