Job Description

Job title: Security Engineer
Location: Flexible - London, Bristol or Edinburgh (Hybrid remote working)
Salary: £54,000-£91,500

Kaluza wants to power a world where net-zero is within everyone’s reach, by building the platform that will accelerate a sustainable, affordable and resilient energy transition. It’s a huge challenge, but often the toughest problems are the most rewarding to solve.

Since launching in 2019, Kaluza’s technology has been empowering some of the biggest energy suppliers to better serve millions of customers.

From revolutionising billing to smart electric vehicle charging, our real-time cloud platforms transform supplier operations, reducing cost to serve and boosting engagement. And most importantly, they enable suppliers' customers to drive decarbonisation with smart, low carbon technologies.

Where in the world of Kaluza will I be working? 

You'll be joining the technology area of Kaluza. We are a large team of both data-led and product focused Software and Production Engineers, pushing the boundaries of technology working at an outstanding scale. As a collective we strive for engineering greatness and ensuring best practices across the board of the engineering community.

You will be joining the Security Engineering team whose purpose is to ensure Kaluza’s greenfield Energy Platform is secure for all our customers while enabling our product teams to ship awesome features.

This is a multifaceted role where you’ll be exposed to the full stack and will work across technologies including GCP, AWS, Kubernetes and Kafka. You’ll be focusing on projects spanning infrastructure, release engineering and security monitoring.

As part of the Security Engineering team we want to build solutions and insights that will allow us to meet a very high security calibre, while maintaining a fast delivery pace expected in a modern software system. We believe this happens through tight collaboration between Security Engineering and Software Engineering. You will have a strong focus on building relationships across various teams, including design feedback and coaching but most importantly building security improvements in our products.

What will I be doing?

You will be building tools and fostering our security culture to help Kaluza’s product teams rapidly deliver secure systems. Providing those teams with clear actionable advice on what risks and threats they have to their systems. You will also be responsible for defining and evolving security best practices for our greenfield system. Helping teams take action on those practices through your expert training or automation will be key to your success.

Is this the job for me? 

We are looking for excellent security engineers and whilst experience is important, ultimately less so than your demonstrated abilities and attitude.

The following skills and experience would be beneficial:

  • Knowledge and experience in secure software practices
  • Scripting and software engineering skills; we don’t mind what language! (Python, Scala, Clojure, Java etc.)
  • Awareness of common software security flaws and web application security best practices (OWASP top 10, CWE/SANS Top 25)
  • Application security testing 
  • AWS/GCP security best practices
  • Kubernetes security best practices
  • Container vulnerability management
  • Open Source dependency scanning
  • Web application firewalls
  • Logging, monitoring and alerting on security events
  • Thorough knowledge of CI/CD and DevOps principles and security considerations
  • Experience with infrastructure-as-code

Additional skills

  • An inquisitive and curious approach, with confidence to tackle difficult problems
  • Rapid adoptee of merit-proven new approaches & technologies
  • Problem solver / structured thinker
  • Always happy to help and a natural sharer of knowledge

Here at Kaluza we are 100% committed to providing a reliable platform for our clients. As part of that commitment, our engineering ownership model is “you build it, you own it.”  Our engineering teams have a high sense of ownership and support their critical services both in and out of normal working hours.

Kaluza’s vision is to power a world where net-zero is within everyone’s reach. Would you be interested in joining us to help achieve this?

We want the best people

We’re keen to meet people from all walks of life — our view is that the more inclusive we are, the better our work will be. We want to build teams which represent a variety of experiences, perspectives and skills, and we recognise talent on the basis of merit and potential.
