Senior Software Engineer

Our world leading Time & Frequency department is seeking a Senior Software Engineer with expertise in Unix/Linux software development and containerisation.

This is an exceptional opportunity to join the global authority in precision timing at a defining moment for UK digital infrastructure.

Backed by a government investment of £180 million in the National Timing Centre (NTC) programme, we are developing a world first resilient time distribution capability that will provide industry with a robust complement to satellite systems (such as GPS) - which are increasingly vulnerable to disruption from solar storms, jamming and spoofing. This will underpin essential services, including:

• Telecommunications
• Online banking
• Emergency response
• Transport networks
• Wider digital and data driven operations

Together, these services form the backbone of modern society - and your leadership will help ensure they remain secure, reliable and robust even if global navigation satellite systems fail.

Key Responsibilities

• Provide technical leadership within the software team, setting and promoting best practice in software design, coding standards, security, testing and CI/CD pipelines.
• Design, develop and implement robust, secure and highly available software solutions for production environments, taking end to end responsibility across the SDLC.
• Identify and implement continuous improvements to software architecture, development processes and operational practices, acting as a process owner for agreed engineering standards and approaches.
• Lead a small software team or workstream, providing direction, prioritisation and technical decision making while mentoring engineers and assuring delivery quality.
• Act as Scrum Master when required, leading agile ceremonies, supporting effective delivery, and continuously improving team ways of working.

Essential Experience and Qualifications

• Experience building robust software deployed into high availability production environments, with a strong emphasis on software quality, reliability, and maintainability.
• Proven experience working within Agile/Scrum delivery teams, contributing to iterative, collaborative software development.
• Software development in a Unix/Linux environment, using any modern language (with Python preferred).
• Hands on experience with container runtimes and containerising applications.
• Experience designing, building, or maintaining CI/CD pipelines to support automated build, test, and deployment processes.

Requirements

To work at NPL, you will need to obtain BPSS security clearance. For this role in the Time and Frequency department, you must have an SC clearance with no restrictions, or the ability to obtain an SC clearance.

We actively recruit citizens of all backgrounds; however, due to the nature of our work, nationality, residency, and security requirements may be more tightly defined. You will be asked about these throughout the recruitment process.
