Our world-leading Time & Frequency department are seeking an experienced Scientist to develop some of the most innovative uses of ultra-precise measurements over optical fibre links.

We are now working in a hybrid way, with a mix of remote and office working. We strive to offer a great work life balance - if you are looking for full time, part time or flexible options, we will try to make this work where business possible. This will be dependent on the kind of role you do and part of the business you work in.

This permanent, full-time position comes with a generous salary and benefits package.

You’ll enjoy collaborating with prominent Scientists and Engineers to conceive, design, build state-of-the-art ultra-stable setups to perform innovative tests on optical fibre systems and links.

You’ll enjoy sharing responsibility for the development of research on applications of ultra-stable interferometry for a range of scientific and societal applications; such as

1. Earthquake and tsunami detection using seafloor cables

2. Ocean signal monitoring such as currents and tides

3. Distant atomic optical clock comparison over fibre links, including over intercontinental distances

4. Advanced laser stabilisation techniques

NPL has pioneered sensing techniques for the detection of earthquakes and ocean currents using the existing undersea network of optical fibres and is looking at expanding the knowledge and applications of these techniques.

This role provides exciting opportunities to publish your work in high-impact academic journals and present it at prestigious international conferences, contributing to a rapidly growing field of research.

We believe that diversity and unique perspectives are key to the success of our science projects. For this role, we particularly encourage applications from candidates underrepresented in STEM disciplines, in particular women, disabled, black, Asian and minority ethnic candidates. 

Reporting to a Senior Scientist, you’ll enjoy developing applications of ultra-stable interferometry - from the dissemination of ultra-stable and ultra-accurate signals, to detecting earthquakes with seafloor optical cables.

To be successful in this role, you will have the following skills, experience, and qualifications:

Essential:

• Demonstrable laboratory experience - planning, designing and running optical experiments with the ability to identify problems, then propose and implement solutions. Experience with fibre optics.
• Practical and recent experience with laboratory electronics
• A PhD in a photonics-related subject (such as Fibre Optics, Optical Fibre Sensing, Laser Stabilisation, etc.) or equivalent experience. We may also consider strong candidates with a BSc in a relevant area (such as Physics or Engineering)
• Proven experience coding for experiment control and data analysis using one or more of these languages: LabVIEW, Python, C.Matlab or Mathematica
• Exceptional written and oral communication skills, with the ability to simplify complex technical concepts
• Team player with a proactive, never-fail attitude in the face of ambiguous situations

• Practical knowledge of feedback systems (PID controls)
• Knowledge of frequency metrology concepts (frequency stability, Allan deviation, phase noise, etc…)
• OFDR / OTDR knowledge

The National Physical Laboratory (NPL) is a world-leading centre of excellence that provides cutting-edge measurement science, engineering and technology to underpin prosperity and quality of life in the UK. 

NPL and DSIT have strong commitments to diversity and equality of opportunity, and welcome applications from candidates irrespective of their background, gender, race, sexual orientation, religion, or age, providing they meet the required criteria. Applications from women, disabled and black, Asian and minority ethnic candidates in particular are encouraged. All disabled candidates (as defined by the Equality Act 2010) who satisfy the minimum criteria for the role will be guaranteed an interview under the Disability Confident Scheme. 

At NPL, we believe our success is a result of the diversity and talent of our people. We strive to nurture and respect individuals to ensure everyone feels valued by treating everyone on the basis of their own individual merits and abilities regardless of their own or perceived identity, as part of our commitment to diversity & inclusion, we hold memberships and accreditations to ensure we’re creating an environment where all our colleagues feel supported and welcome, please see our Diversity & Inclusion page.

 We are committed to the health and well-being of our employees. Flexible working and social activities are embedded in our culture to create a positive work-life balance, along with a broad range of benefits. Our values are at the heart of what we do, and they shape the way we interact, develop our people and celebrate success.
