About You

• Do you have a proven engineering background with extensive cloud experience?
• Can you demonstrate your ability to lead and grow high-performing teams in fast-paced, agile environments?
  
  

About The Role

We’re seeking an experienced and dynamic Principal Engineer to join our Technology and Transformation leadership team. This is a pivotal role where you’ll shape and build a brand-new technology capability for us. You’ll drive key technology initiatives, oversee project delivery, and ensure our solutions align with strategic business objectives.

This role offers a unique opportunity to influence the future of Billing Finance as we evolve into a modern, technology-led organisation. We operate within a Scaled Agile Framework, focusing on delivering value-driven outcomes, with technology as a true business enabler.

Leadership and Strategy

• You’ll own the overall Technology and Engineering strategy for Billing, setting the direction for how technology supports business growth.
• You’ll partner with senior stakeholders to define the technology roadmap, ensuring alignment with broader business goals and will lead, mentor, and develop a high-performing technology team whilst fostering a culture of continuous improvement and professional growth.
  
  

Technical Oversight

• You’ll oversee all aspects of Data, Infrastructure, Integrations, Test Engineering, and Architecture for the Billing domain and will drive the design and implementation of scalable, secure, and high-performance technology solutions.
• You’ll manage our SaaS-based core systems, key system integrations, and a comprehensive data platform to support business operations and will take ownership of internal cloud infrastructure, CI/CD pipelines, and DevOps engineering across the entire technology stack. You’ll also evaluate, select, and implement software, automation tools, and data solutions that enhance business efficiency.
• Whilst this is primarily a leadership role, you’ll also be willing to engage in technical details, review code, and support delivery teams when necessary.
  
  

Collaboration & Communication

• You’ll work closely with cross-functional teams to define project scope, objectives, and deliverables and will translate complex technical concepts into clear, actionable insights for non-technical stakeholders. You’ll also facilitate strong communication between engineering teams and business leaders to maintain alignment on priorities.
  
  

Innovation & Continuous Improvement

• You’ll stay up to date with industry trends, emerging technologies, and best practices to inform strategic decisions and will conduct regular assessments of technology performance, identifying opportunities for optimisation and innovation.
  
  

Why Join Us?

This is a rare opportunity to define and shape a new technology function from the ground up. You’ll have the autonomy to influence architecture, build and lead a talented team, and play a key role in transforming Billing Finance into a truly modern, technology-driven business.

You won’t just be managing processes—you’ll be a strategic leader, driving the adoption of cutting-edge technologies and helping us evolve into a company where technology is at the heart of everything we do. If you’re passionate about engineering excellence, innovative thinking, and making a tangible impact, this is the role for you.

Experience

Technical Expertise:

• Established background in modern technology stacks, cloud-native architectures, and SaaS solutions.
• A strong engineering background with extensive cloud experience—you’ll be confident operating in a cloud-first environment.
• Proven experience in technology leadership roles, with a solid understanding of software development, data engineering, and modern architectural principles.
• Proficiency in programming languages such as Java, Python, or C#, with the ability to engage in technical discussions and code reviews when needed.
• Hands-on experience with cloud platforms (e.g., AWS, Azure) and DevOps practices, including CI/CD pipelines, infrastructure as code, and automation tools.
• Strong analytical and problem-solving skills, capable of troubleshooting complex technical challenges efficiently.
  
  

Leadership & Collaboration

• Demonstrated ability to lead and grow high-performing teams in fast-paced, agile environments.
• Excellent communication skills, with the ability to engage both technical and non-technical stakeholders effectively.
• A strategic thinker with the ability to manage multiple projects, balancing short-term deliverables with long-term goals.
• Experience managing third-party vendors and technology partners to deliver complex solutions preferred but not essential.
• A hands-on, problem-solving mindset, with the ability to dive deep when required while maintaining strategic oversight.
  
  

We’re looking for someone who combines strong technical expertise with proven leadership skills. While we don’t expect candidates to tick every box, you should be able to demonstrate how you would leverage internal resources and external partners to complement your skill set.
