About the Role

Our world-leading Time & Frequency department are seeking a Senior Network Engineer with hands-on infrastructure and network design and implementation experience.

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.

You will be joining our team at an exciting time - we maintain the UK’s National Time Scale, UTC (NPL), and are currently developing a new resilient Time Scale facility that will underpin our Critical National Infrastructure. This will address the risks associated with our dependency on global navigation satellite systems (such as GPS) that are vulnerable to both natural and intentional interference.

You’ll enjoy collaborating with prominent Scientists, Engineers, and Specialists in Cyber Security, to design and implement network infrastructure to time, quality, and cost.

Key responsibilities:

  • Design and Architecture: Develop comprehensive network designs that support the unique needs of scientific and engineering capabilities, ensuring robustness, scalability, and security.
  • Build and Specification: Oversee the specification, selection, and procurement of networking equipment, ensuring compatibility and integration with existing and future scientific instruments.
  • Configuration and Implementation: Configure and deploy networking solutions, including routers, switches, firewalls, and other network devices, tailored to the specific requirements of each project.

  • Security Hygiene: Keep up to date with and apply best practice, collaborating with security specialists.

  • Testing: Execute integration tests where appropriate, meticulously documenting, and analysing results to identify potential vulnerabilities and areas for improvement.
  • Troubleshooting and Support: Provide expert-level troubleshooting for complex network issues, ensuring minimal downtime and optimal performance of scientific equipment and IT infrastructure.
  • Collaboration and Leadership: Work closely with scientific, engineering and IT leadership to ensure technology solutions align with research objectives. Mentor junior staff and lead by example in technical excellence.

  • Quality Assurance Coordination: Maintain meticulous records to support quality assurance processes.

  • Stakeholder Engagement: Engage with a diverse array of stakeholders, to ensure networking requirements are met and understood.

This role offers exciting opportunities to collaborate with subject-matter experts across the business.
