Would you like to be instrumental in enabling the next generation of semi-conductors?

As a Senior Applications Engineer
, you’re owning the bridge between cutting‑edge technology and real‑world customer needs. You’re working across the full product lifecycle, shaping how our solutions perform in the field and how they evolve. You’re also getting hands‑on with customers globally, making a direct impact where it matters most.

If this is you, read on….

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

We welcome applicants from all backgrounds and aim to create a fair, supportive recruitment process.

To keep things clear, this role needs someone who already has the permanent right to work in the UK. If a role calls for unique expertise that’s hard to find locally, we may explore sponsorship options — though this is uncommon.

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.
