About the role

The role itself will be focused on various control systems, which may include but are not limited to motion control systems, tuning, Piezo control, anti-vibration systems, etc.

A typical day for a Senior Mechatronics Engineer could look like this

Driving development work to strengthen existing control systems while helping create new, forward‑thinking solutions
Applying control theory to shape system and subsystem requirements
Actively assessing and uplifting system performance
Supporting ultra‑precise nanometre‑level movements with accuracy under pressure
Handling sub‑nanometre noise challenges with a solutions‑focused mindset
Partnering closely with stakeholders to spot issues early and guide them toward effective resolutions
Creating and maintaining documentation to keep teams informed
Leading as a subject‑matter expert, offering guidance and technical insight
Leading technical development work and approaching failure analysis
Planning technical activities and getting hands‑on with equipment to prove and validate the performance of your designs
Feeding forward insights, learning and improvements into future developments
Presenting and documenting clear and engaging technical work

Who we are looking for

To succeed as a Senior Mechatronics Engineer, we do need you to have experience of

Developing and fine‑tuning precision motion control systems, ideally at the nanometre scale
Hands‑on engineering development, with collaborative approach
Leading on Mechatronic Control Systems and guiding others with clarity
Feedback and Feedforward loops, with a thoughtful approach to problem‑solving
Effective application of PID processes
Working with Bode plots, Pole‑Zero plots, system transfer functions and stability criteria, considering both time and frequency domain performance
Using programming languages such as LabVIEW, Python or MATLAB; FPGA (VHDL) knowledge is a lovely bonus
Experience designing tests and setting pass/fail criteria across electrical/electronic and mechanical disciplines
Ability to manage your own projects with care — including time planning, resource coordination and clear, supportive updates to key stakeholders

Nice to have

Knowledge of digital filtering (ideally in FPGAs)

Experience of driving piezos, and knowledge of hysteresis in piezos.

Knowledge of metrology and measurement systems.
