Why a CV for this job?

94% of employers say their filters drop qualified candidates whose CV does not match the ad's exact criteria (Harvard Business School, 2021).

  • They see what they asked for, first. Your experience that matches the ad leads, in the ad's own words, so someone skimming finds it in seconds.
  • It gets past the software. Many larger employers use software that ranks CVs by how closely they match the ad, often before anyone reads them.
  • In the language of the ad. An ad written in Spanish gets a CV in Spanish, even when yours is in Portuguese.
  • Your facts, nothing invented. Your own experience, reordered and reworded. What the ad wants and your CV does not show is listed for you to add, only if it is true. You check it before you send it.

Applications Engineer, Semiconductor Metrology / AFM

Gyeongju, South Korea / Customer Site

Graduate to Senior level roles available

On-site role | Up to 50% travel | International training

Salary:

Junior Applications Engineer: ₩65,000,000–₩80,000,000

Applications Engineer: ₩80,000,000–₩105,000,000

Senior Applications Engineer: ₩100,000,000–₩135,000,000

You'll also receive our local Gyeongju, South Korea benefits package and opportunities to develop your career within a growing international semiconductor technology business.

Your AFM expertise could help shape the next generation of semiconductor manufacturing.

If you work with Atomic Force Microscopy (AFM), Scanning Probe Microscopy (SPM), semiconductor metrology, advanced instrumentation or nanoscale measurement, we'd like to talk to you.

At Infinitesima, we're developing AFM technology specifically for the demands of semiconductor manufacturing.

Our technology helps semiconductor manufacturers measure and understand increasingly complex structures at the nanoscale, and we're growing our Applications Engineering capability in Gyeongju, South Korea.

We're interested in people at all career stages, from talented graduates and early-career scientists through to experienced Applications Engineers and recognised AFM or semiconductor metrology specialists.

The role

You'll become one of the technical links between Infinitesima's AFM technology and our semiconductor customers in Japan.

Depending on your experience, you'll:

  • Develop and optimise AFM measurement methodologies
  • Work directly with semiconductor customers on complex metrology challenges
  • Develop measurement recipes, workflows and applications
  • Analyse nanoscale measurement data and communicate your findings
  • Troubleshoot challenging customer applications
  • Conduct technical demonstrations and proof-of-capability work
  • Deliver technical training and consultation
  • Feed customer insights back into our Product and Engineering teams
  • Collaborate internationally with scientists, engineers and commercial colleagues
  • Help influence the development of future semiconductor metrology technology

For experienced hires, there is scope to become a recognised technical authority within our global Applications Engineering organisation.

Who we're looking for

Experienced candidates

You may already be working as an:

  • Applications Engineer / Application Engineer
  • Field Applications Engineer
  • Semiconductor Metrology Engineer
  • AFM Applications Scientist
  • AFM Engineer
  • SPM Engineer
  • Process Engineer
  • Equipment Engineer
  • Metrology Engineer
  • Customer Applications Engineer
  • Technical Support Engineer

Experience with AFM or SPM is particularly attractive.

We'd also love to hear from semiconductor professionals working with:

  • Advanced semiconductor metrology
  • Wafer inspection or characterisation
  • Thin-film or surface measurement
  • Nanotechnology
  • Advanced scientific instrumentation
  • Semiconductor process development
  • Semiconductor equipment

You don't need to tick every box.

Specialist people rarely fit neatly into a job description.

Graduates and early-career scientists

Already getting hands-on with AFM, SPM or nanoscale characterisation at university or during postgraduate research?

Don't assume you need years of semiconductor industry experience.

We'd particularly like to hear from graduates, Master's and PhD candidates in:

  • Physics
  • Applied Physics
  • Materials Science
  • Nanoscience / Nanotechnology
  • Semiconductor Engineering
  • Electronic Engineering
  • Mechanical Engineering
  • Surface Science
  • Related scientific or engineering disciplines

Research or practical laboratory experience involving AFM/SPM, surface characterisation or advanced instrumentation could be a great starting point.

Gyeongju, South Korea location and travel

This bit matters, so we're being upfront.

This is not a remote or hybrid position.

  • You'll work on-site at our customer location in Gyeongju, South Korea every working day
  • You must be willing and able to relocate within reasonable travelling distance of the customer site
  • The role involves up to 50% domestic and international travel once fully trained.
  • You'll work closely with colleagues across South Korea, the UK and our wider global organisation
  • All our Global Apps colleagues come to our HQ in beautiful Oxfordshire for their 3-week induction so that you can get to know your new team, build your skills and make new friends.
  • Infinitesima provides travel and accommodation support for this initial UK training

If international exposure, customer-facing technical problem solving and being close to leading-edge semiconductor manufacturing sounds exciting rather than daunting, you'll probably enjoy this role.

Why Infinitesima?

This isn't Applications Engineering where you're simply supporting an established product.

You'll be joining a growing technology company tackling measurement problems created by the increasing complexity of semiconductor manufacturing.

That means:

  • Genuinely differentiated AFM technology
  • Direct exposure to advanced semiconductor manufacturing
  • Complex technical problems rather than routine support
  • International collaboration
  • Significant customer interaction
  • Global travel and career exposure
  • Close relationships with Product, Engineering and scientific teams
  • The opportunity to become a highly specialised semiconductor metrology expert

If you're already an AFM specialist, we'd particularly like to hear from you.

There aren't many of you. We know that.
