Principal Software Engineer - Cyber Security Analytics

Principal Software Engineer - Data Visualisation / Dashboard Development

Edinburgh, UK | Fully Remote (UK-based)

Engineering | Cyber Security

£95,000 & Benefits

Ever wanted your dashboards to actually defend the internet?

This role does exactly that.

We are recruiting on behalf of a high-growth cyber security technology company that protects some of the world’s most critical online services from large-scale DDoS and application attacks. Their software sits right at the heart of customer networks- and when it works (which it must), entire businesses stay online.

They’re now expanding their world-class engineering team and are looking for a Principal-level expert to lead the charge on network and security analytics.

The Opportunity

This is not a “keep-the-lights-on” role.

You’ll own and lead the design and development of sophisticated, high-performance dashboards used to visualise real-time network and security data. You’ll set technical direction, mentor engineers, and build analytics that help customers instantly understand and stop complex cyber attacks.

You’ll be trusted to work from first principles, influence architecture, and make decisions that genuinely matter.

What You’ll Be Doing

• Leading a small, highly skilled team focused on network & security analytics
• Designing and building advanced Grafana dashboards running in Kubernetes
• Turning complex data into clear, insightful visualisations
• Developing and reviewing complex queries (Grafana, Splunk, Python)
• Mentoring engineers and shaping technical best practice
• Balancing hands-on development with technical leadership and ownership

What We’re Looking For

Essential

• Strong experience building dashboards and analytics in Python and ideally Grafana
• Proven background leading engineers in an agile environment
• Solid understanding of Linux and AWS
• Excellent communication skills — you can explain complex ideas simply
• A strong technical degree (Computer Science, Maths, Statistics, Engineering, or similar)

Nice to Have

• Knowledge of networking protocols and how the internet actually works
• Experience with Splunk & SPL
• SQL or similar data manipulation skills
• Exposure to network security products
• HTML, CSS, JavaScript
• Data Science or Machine Learning experience

Location & Flexibility

• Edinburgh-based engineers: hybrid working (typically 2 days in office)
• Fully remote options available for the right candidate
• Cutting-edge tech, complex data, and meaningful problems
• A culture that values ownership, curiosity, and smart engineering

If you’re a senior/principal engineer who loves data, networks, and building things that actually matter — this one’s worth a conversation.
