Reward and Benefits
£65,000 to £75,000 (depending on experience)
25 days annual leave, death in service and private healthcare, personal pension contributions of 4% via salary sacrifice, and a generous EMI share scheme
Based in Abingdon, Oxford, UK, we’re a high-calibre team of 100+ people growing fast. Backed by global financial and industry investors including Applied Ventures, we’re building something genuinely impactful.
About the role:
You’re playing a key role in making sure our products meet (and exceed) customer expectations. You’re acting as the voice of the customer internally, feeding insights into Engineering and R&D, while leading application projects that improve performance and user experience.
This is a highly hands-on role with ~50% international travel, working directly with customers and end-users on-site
A typical day for a Senior Applications Engineer could look like this:
- Leading customer demos, characterisation work, and technical evaluations
- Presenting results clearly to both customers and internal teams
- Acting as the go-to contact for application-related support queries
- Troubleshooting complex, multi-disciplinary issues across mechanics, optics, electronics, software, and algorithms
- Collaborating with Engineering and R&D to feed back customer insights
- Driving application projects to improve product performance and user experience
- Supporting and maintaining application lab facilities and equipment
Who we are looking for:
To succeed as a Senior Applications Engineer, we do need you to have experience of:
- Working in the semiconductor industry with a strong hands-on focus
- Leading or supporting characterisation and demonstration activities for metrology equipment
- Supporting customers in a technical or applications-focused role
- Diagnosing complex technical issues across multiple disciplines
- Communicating technical concepts clearly, both written and verbal
Nice to have:
- Experience with Atomic Force Microscopy (AFM)
- Exposure to optical systems (lasers, fibres), electronics, or electro-mechanical systems
- Understanding of semiconductor processes
- Experience with scanning electron microscopes (SEM)
- Any involvement in product marketing or customer-facing technical storytelling
Education / Qualifications:
Either a Master’s degree in Physical Sciences, Engineering, or similar, or a clear equivalent path through relevant experience.
We look for the five Cs from our colleagues:
- Customer Focused – Staying close to customer needs and delivering real value
- Caring – Creating a supportive, respectful environment
- Collaborative – Sharing ideas and solving problems together
- Commitment – Owning your work and following through
- Continuous Improvement – Always learning and pushing things forward
A bit about us:
Infinitesima is a privately owned company founded in 2001 as a spin-out from the University of Bristol. Our team of scientists and engineers is focused on enabling the next generation of semiconductor devices through innovative, world-leading products.
We value different perspectives and believe diversity fuels better thinking and stronger outcomes. If you need any adjustments during the hiring process, just let us know — we’ve got you.
A note on how we run interviews:
We use AI only to transcribe interviews so we can stay fully present with you. It plays no part in decision-making — all hiring decisions are made by people.
Location and work pattern:
You’ll be based in Abingdon (OX14 1RG).
We ask new starters to be on-site during the first 3 months, with flexible hybrid working available after probation.
Infinitesima was spun out of the University of Bristol in 2001 and has been developing innovative metrology solutions which improve speed and precision in the manufacture of semiconductors. The company’s technology combines the 3-dimensional surface detection capability of atomic force microscopy (AFM), with high-speed laser activation and the accuracy of interferometry. The Rapid Probe Microscope (RPM™) is protected by an extensive patent portfolio. The company’s RPM™ technology is being used by leading semiconductor equipment companies globally. Semiconductor devices provide the foundations on which progress in the technology sector are enabled. From Smartphones to Artificial Intelligence, 5G communications to autonomous vehicles, all are made possible through advances in semiconductor processes. Scaling these processes requires sub-nanometer measurement of increasingly complex 3D structures to enable more powerful devices. Based in Abingdon, UK, we are a high calibre team of 80 people and continue to grow. We are backed by global financial and industry investors including Applied Ventures, the strategic venture arm of the industry leading equipment company.
