Location: Abingdon, Oxfordshire
Working pattern: On site during probation, with hybrid flexibility where possible after that
Your recruitment journey:

Ready to take ownership of the performance that makes advanced semiconductor tools genuinely production-ready?
Infinitesima builds high-precision metrology instruments that help enable the next generation of semiconductor devices. Our systems are used in demanding fab environments, where performance is not just about taking a great measurement. The tool also needs to move fast, land accurately, behave repeatably, and be quick to set up.
We are looking for a Systems Engineer – Platform Performance to own key performance functions across Metron, our high-throughput Atomic Force Microscopy platform. This is a role for someone who enjoys working across hardware, software, data and real-world system behaviour, and who wants genuine technical influence rather than a narrow engineering lane. The role owns throughput, wafer navigation accuracy, repeatability and time-to-recipe system functions for Metron.
You will work closely with system function architects, engineering teams and stakeholders to define measurable requirements, build performance budgets, validate assumptions and drive improvements. Expect a strong mix of requirements definition, test planning, tool data analysis, integration support and technical trade-off work across mechanics, electronics, optics, control systems, software, motion and wafer handling.
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.
What you will be doing
- Owning system-level performance areas including throughput, wafer navigation, repeatability and time-to-recipe.
- Translating customer and stakeholder needs into clear, measurable platform performance specifications.
- Defining and managing performance budgets across wafer handling, stage motion, measurement workflows and data processing.
- Developing and running test plans to validate performance against requirements.
- Using tool logs, instrument data and evidence-based analysis to find where time, accuracy or repeatability are being lost.
- Working with engineering, quality and project teams to support integration, troubleshoot issues and drive practical improvements.
- Helping make the instrument faster to run, quicker to set up and more predictable in production use.
What we are looking for
You will likely have experience in complex, high-precision or multi-disciplinary instrumentation. Semiconductor experience would be a strong bonus, but it is not a dealbreaker.
You will need experience with:
- Systems engineering, platform performance, throughput, timing, motion or positioning.
- Requirements definition and measurable specification writing.
- Analysing system-level data, logs or test results to identify performance limits.
- Working across disciplines such as mechanics, electronics, optics, software, control systems or motion systems.
- Instrument testing, verification and validation.
- Data analysis using tools such as Python, MATLAB or Excel.
Experience with wafer handling, stage/navigation systems, automation, Atomic Force Microscopy, C# or Python-based test automation would be useful, but not essential.
Why join Infinitesima?
You will join a growing, high-calibre team of 100+ people based in Abingdon, backed by global financial and industry investors, including Applied Ventures.
