Field Service Engineer – Semiconductor Metrology
Based in the UK, working globally
Salary: £36,000 – £45,000 + EMI Share Options + Private Healthcare
Keep the machines running that measure the chips powering the modern world.
Semiconductor metrology systems don't fix themselves. Someone has to travel to the site, diagnose the fault, and get a multi-million-pound tool back online for customers who cannot afford downtime. We're looking for that person.
Infinitesima builds the AFM-based metrology systems the world's biggest semiconductor manufacturers rely on to measure chips down to the nanometre. We need a Field Service Engineer to keep those systems running — worldwide.
The role involves travel, sometimes at short notice, sometimes for extended periods, to our global and EU operations. If you're looking for a desk-bound, nine-to-five role, this isn't it. If the idea of travelling internationally to solve genuinely difficult technical problems appeals to you, read on.
What the role involves
- Install, commission, and upgrade advanced metrology systems at customer sites worldwide
- Deliver preventative maintenance and corrective repair activities
- Diagnose complex electromechanical, optical, and system-level faults
- Support customers remotely and on-site to keep uptime and performance where they need to be
- Train and mentor distributors and customer service teams
- Monitor system performance and spot opportunities for improvement before they become problems
- Feed customer insight back to engineering to shape future products
- Support production, test, and commissioning activities at our Abingdon HQ when required
- Help build a scalable, world-class customer support function
Who we're looking for:
Your background could be in semiconductor equipment, scientific instrumentation, lasers, optics, automation, or complex electromechanical systems — what matters most is that you can diagnose a fault under pressure and explain it clearly to a customer.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
We're especially interested in engineers with experience in:
- Semiconductor equipment or semiconductor manufacturing environments
- Semiconductor metrology or process control equipment
- Scientific instruments or analytical systems
- Optical, laser, or photonics systems
- Precision electromechanical equipment
- Vacuum, automation, or high-tech manufacturing systems
Essential experience:
- Proven track record installing, maintaining, and troubleshooting complex technical equipment
- Comfortable diagnosing faults across electrical, mechanical, and software-controlled systems
- Strong customer-facing skills, able to build trust under pressure
- Able to manage multiple priorities in a fast-paced technical environment
- Strong problem-solving and communication skills
- Willing and able to travel internationally on a regular basis, as the role requires
Nice to have (not deal-breakers):
- Semiconductor industry experience
- AFM, microscopy, or metrology systems knowledge
- Lasers, optics, or fibre-optic technologies
- Networking and software configuration skills
- Scale-up or high-growth tech company experience
- High-voltage systems experience
Qualifications: A degree in Engineering, Physics, or a related discipline, or equivalent experience gained through an apprenticeship, military service, field engineering, or other hands-on industry experience. We care about demonstrated capability as much as formal qualifications.
