Reward and Benefits:

• £52,000 to £72,000 (depending on experience)
• 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 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.
  
  
  
  

Education / Qualifications:

Either a BSc/BEng in Physics, Engineering or similar, or a clear equivalent path through relevant apprenticeship or accumulated experience.

We look for these attributes for our team:

• Self-management: Able to work independently, setting priorities for own work based upon the company goals and targets.
• Teamwork: Engages with other members of the company to bring the best solutions to the problem. Recognise the value that fellow company members bring to enhance own abilities. Supports colleagues with their tasks when critical to the company goals.
• Impact and Influence: Establishes themselves as the knowledge centre in their own field.
• Ownership & Initiative: React and address both short- and medium-term issues and proactively takes action to solve them.
• Results Orientation: Focus on the company goal, avoid distraction, making timely decisions to achieve the target.
