• Lead technical workstreams, reporting to internal and external stakeholders
• Mentoring and development of team members.
• Integration of optical devices into opto-mechanical assemblies.
• Design of precision components, with tolerances in the µm range.
• Enabling user friendly designs and interfaces for the wider team.
• Developing systems suitable for use in ultra high vacuum (UHV) and cryogenic environments.
• Helping others in the company develop technical solutions with your expertise.

What we're looking for

• An undergraduate or postgraduate degree in a relevant STEM field.
