Ready to make massive impact with microscopic magic?
Do you have a strong background in reliability and availability engineering, including availability matrix creation and management?
Infinitesima builds the metrology instruments that enable the next generation of semiconductor devices – and our customers depend on those instruments being reliable, available, manufacturable, serviceable and safe. As System Function Engineer for RAMS (Reliability, Availability, Manufacturability and Serviceability), you will own how well our instruments deliver against these system functions, working hand-in-hand with our system function architects and contributing to the safety of our products.

Reward and Benefits:
- Salary £68,000 to 78,000
- 25 days annual leave, death in service and private health care benefits, personal pension contributions of 4% with salary sacrifice and a generous EMI Share scheme.
Based in Abingdon, Oxford, UK, we are a high calibre team of 100 plus people and we are growing fast. We are backed by global financial and industry investors including Applied Ventures, the strategic venture arm of the industry leading equipment company.
About the role:
The System Function Engineer – RAMS owns the Reliability, Availability, Manufacturability and Serviceability system functions across Infinitesima’s instruments. You will translate product and customer needs into measurable RAMS requirements and budgets, and ensure that designs across optics, mechanics, electronics, control and software meet them.
Day to day, you will work hand-in-hand with the system function architects. They are the people you provide RAMS budgets to, and you will operate a closed-loop relationship with them: specifications, budget, prioritisation, design, test, data, analysis – and repeat. Keeping that loop tight, evidence-based and moving is central to the role.
This role also contributes to product safety. You will help drive safety and regulatory compliance into our instruments – identifying hazards, building safety requirements into the design, and supporting the compliance activities needed to bring products to market safely.
A typical day for a System Function Engineer could look like this:
- Working closely with the system function architects – providing and negotiating RAMS budgets and running the closed loop of specifications, budget, prioritisation, design, test, data and analysis
- Defining and managing reliability and availability targets, including creating and maintaining the availability matrix
- Driving manufacturability and serviceability into the design, and verifying that the design meets them
- Contributing to product safety and regulatory compliance – helping identify hazards, building safety requirements into the design, and supporting compliance activities
- Participating in failure-mode analyses (e.g. FMEA) led at the system-function-architect level, and feeding RAMS insight into them
- Analysing field and service data to drive reliability and availability improvement, and contributing to Verification and Validation planning
Who we are looking for:
To succeed as a System Function Engineer – RAMS, we do need you to have experience of:
- Working with complex instrumentation for technology or science – multi-disciplinary, high-precision and/or large-scale
- Reliability and availability engineering, including availability matrix creation and management is crucial for this role
- Product safety and regulatory compliance – contributing safety requirements and hazard analysis into the design
- Working across some of the following disciplines: mechanics, electronics, optics, software, control systems, motion systems or similar
- Instrument testing, Verification and Validation
- Data analysis tools such as Python, Matlab or Excel
Nice to have:
- Machinery / equipment safety standards and CE/UKCA marking (SEMI S2 a strong plus)
- Experience analysing field or service reliability and availability data
- Familiarity with failure-mode and fault-tree analysis methods (e.g. FMEA, FTA)
- Manufacturability and serviceability design experience (design for manufacture / design for service)
Education / Qualifications:
Either a BSc/BEng/MSc in Engineering, Physics or similar, or a clear equivalent path through relevant apprenticeship or accumulated experience.
We look for the five Cs from our colleagues:
- Customer Focused – Staying close to customer needs and consistently delivering value that builds trust.
- Caring – Creating a supportive environment where people look out for each other and can thrive.
- Collaborative – Sharing ideas openly, communicating clearly, and working together to solve problems.
- Commitment – Taking ownership, following through on promises, and acting with integrity.
- Continuous Improvement – Always learning, challenging the status quo, and improving how we work and deliver.
