About the role
A typical day for a Senior Software Engineer (C#) could look like this:
- Designing and building slick C#/.NET software that powers next‑level AFM semiconductor inspection – basically levelling up nanoscale tech
- Running real‑time control loops that keep nanometre‑scale motion smooth, stable, and drama‑free
- Creating operator dashboards and HMI tools that are actually nice to use
- Plugging software into motion controllers, piezo actuators, and high‑res sensors
- Boosting system performance so scans are sharper, images load faster, and data processing hits different
- Keeping everything aligned with cleanroom standards and safety
- Teaming up with hardware, optics, electronics, and applications crews to deliver tightly integrated systems
- Testing, validating, and stress‑checking everything to make sure it meets ISO, IEC, and semiconductor‑level expectations
- Mentoring junior engineers, sharing the clever stuff, and helping shape software architecture that’s clean, scalable, and future‑proof
