Hybrid

We believe that through collaboration and connection with our colleagues we can achieve great things. Our hybrid working approach allows our people to work both in the office and at home, providing the flexibility and resources you need to succeed in your role. We don't require you to be in on specific days; instead, we ask people to come into the office 2-3 days each week, for at least 8 days per month. You should work with your line manager to understand what their expectations are for you, your specific role and your team.
  

Who We Are

We’re here to build a network the UK can count on – one that connects people, places and potential. Because no matter where you live, what your background is, or how you get online – we think everyone deserves the same chance to stay connected, and with VodafoneThree, that future’s being built – today.

We’re creating more than the UK’s best network. We’re helping close the digital divide, empower communities and drive meaningful progress.

We believe that everyone should feel they belong. Whoever you are and whatever your story, there’s space for you here. We’re building a workplace where different perspectives are welcomed, voices are heard, and everyone feels safe to show up as themselves.

You’ll join a team that genuinely cares – about each other, about our customers, and about the future we’re building. From day one, you’ll be welcomed, valued and encouraged to bring your whole self to work.

What you’ll do

In his role, within VodafoneThree's Performance and Chaos Engineering (PaCE) team, you will play a key role in enabling engineering teams to deliver scalable, resilient, and high-performing digital services. PaCE is responsible for embedding performance, resilience, and reliability practices throughout the software development lifecycle, helping teams identify and address risks early and build confidence in their solutions before they reach production.

Working closely with product, platform, development, and Site Reliability Engineering teams, you will champion a shift-left approach to performance and resilience engineering. Your focus will be on providing the frameworks, tooling, standards, and automation that enable teams to validate scalability, reliability, and operational readiness from the earliest stages of design and development.

Your expertise in software engineering, performance testing, observability, and automation will help drive the adoption of engineering best practices across the organisation. You will lead initiatives to integrate performance and resilience validation into CI/CD pipelines, establish meaningful service level objectives (SLOs), and develop self-service capabilities that empower teams to identify bottlenecks, validate system behaviour under load, and assess failure scenarios independently.
 
Through collaboration, coaching, and continuous improvement, you will help cultivate a culture where performance, resilience, and operational excellence are shared responsibilities. By leveraging data-driven insights, experimentation, and automation, you will enable teams to deliver services that are reliable, scalable, and capable of supporting VodafoneThree's evolving customer and business demands.
