Senior Engineer - Mass Metrology in London

About the Role

NPL Is looking to recruit a Senior Engineer to join the Mass Metrology Group.

To be successful in this Engineering role, you'll be recognised for your technical expertise and ability to lead within your field.

You will have a strong scientific or engineering background, supported by a track record of delivering impactful research, innovation, or technical projects.

Publications or other recognised contributions to your discipline would be advantageous.

Most importantly, we're looking for someone who is collaborative, driven, and excited to thrive in a dynamic and innovative environment.

As a leading National Measurement Institute, NPL creates state of the art measurement facilities translating physics‑based research into world leading measurement standards and equipment.

The Mass Metrology group has a pipeline of instrumentation projects.

We are seeking a scientist or engineer with experience of designing, building and validating novel measurement instruments.

The right candidate will help to realise the strategy, build leadership in the area and create capabilities delivering substantial impact.

Opportunities are available to apply your problem‑solving skills and instruments knowledge to:

• Development, testing and validation of a novel electro‑magnetic Kibble balance based on a seismometer principle to derive the SI unit of mass (kg) via the Planck constant.
• Transforming the proof‑of‑concept Kibble balance into a reliable facility that can be used routinely to deliver the UK mass scale and provide a reference instrument for other national laboratories.
• Design of a new generation of servo‑hydraulic force machines to provide the UK’s reference standard for force above 1 MN.
• Evolution of Kibble balance technologies to create instruments to provide new capabilities in the fields such as micro‑force, torque and precision weighing.

About You

What you will bring to the role

• Strong understanding of physics, instrumentation, error budgets and precision measurement systems, ideally with a degree or higher qualification in a relevant subject.
• Curiosity and the drive to learn and apply new knowledge.
• Experience working on complex technical systems (e. g. instrumentation, research facilities, or bespoke engineered systems), applying cutting‑edge innovation and transitioning concepts through to operation.
• Strong data analysis skills and, ideally, an experienced user of packages such as Python, MATLAB or COMSOL.

Able to create and manage measurement models to deliver robust uncertainty budgets.

• Experience of developing, integrating and testing software and hardware within a systems engineering process.
• Expertise with one or more of laser interferometry, electro‑mechanical and/or opto‑mechanical control, motion systems, vibration control, PID control loops, precision low‑noise voltage measurement, FPGA programming.
• Strong written and oral communication skills with the ability to explain complex technical concepts to stakeholders.
• An entrepreneurial approach, able to spot opportunities and engage with stakeholders to refine and deliver solutions.
• Ideally having or working towards Chartered Engineer or Scientist status with a relevant Institution.
