Senior Technical Support Engineer - Semiconductor Systems

Senior Technical Support Engineer - Semiconductor Systems Semiconductor Equipment | Motion Control | Advanced Automation £60,000 - £75,000 + Bonus + Private Healthcare BUPA + Share Options Abingdon, Oxfordshire (Hybrid) Solve the problems nobody else can. Infinitesima is developing breakthrough semiconductor metrology technology that enables the world's leading chip manufacturers to measure devices at previously impossible levels of precision. As our technology scales globally, we're looking for a Senior Systems Engineer who thrives on solving complex technical challenges spanning software, automation, motion control, electronics and high-precision instrumentation. This is a role for engineers who enjoy getting to the root cause of difficult problems, understanding how complete systems interact and becoming the person others turn to when the answer isn't obvious. If you're currently working within semiconductor equipment, robotics, scientific instrumentation, advanced manufacturing or precision engineering, this could be the challenge you've been looking for. Why engineers join us You'll work on technology that combines: • Nanometre-scale motion control • Precision positioning systems • Semiconductor automation • Robotics and wafer handling • Software-driven instrumentation • Advanced control systems • High-performance electromechanical assemblies Most importantly, you'll have direct influence over how future generations of our products are designed, improved and deployed. This isn't a role where you'll simply report problems. You'll help solve them permanently. What you'll be doing Own the toughest technical challenges • Lead investigations into complex system-level issues across customer and manufacturing environments. • Diagnose problems spanning software, firmware, automation, controls, electronics and mechanical subsystems. • Drive rapid resolution of high-priority technical escalations. • Act as a senior technical authority supporting Customer Success, Applications and Engineering teams. Become a system expert • Analyse motion control performance and closed-loop control behaviour. • Investigate sensor feedback, positioning accuracy and automation performance. • Identify failure modes across interconnected hardware and software systems. • Support optimisation of high-precision semiconductor equipment. Shape the next generation of products • Conduct structured root cause investigations. • Identify recurring issues and long-term corrective actions. • Feed technical findings directly into Product Development and Engineering. • Influence reliability, serviceability and future product design. Raise technical capability across the business • Develop troubleshooting tools and diagnostic procedures. • Create technical knowledge resources. • Support training and coaching activities. • Help build deeper system understanding across multiple disciplines. We're keen to hear from engineers with experience in: • Semiconductor equipment • Semiconductor metrology • Robotics • Motion control • Automation systems • Scientific instrumentation • Microscopy • Photonics and optics • Precision engineering • Advanced manufacturing equipment • Complex electromechanical systems What you'll bring Essential • Experience troubleshooting complex technical systems. • Strong analytical and root cause investigation skills. • Understanding of motion control, automation or precision positioning technologies. • Ability to work across software, mechanical, electrical and systems domains. • Confidence communicating technical issues to a range of audiences. Desirable • Semiconductor industry experience. • Semiconductor equipment or metrology systems knowledge. • Automation or robotics integration exper
