Crynodeb
This hybrid role offers a great balance of home and office working. You’ll join your colleagues in our office at least 2 to 3 days per week.
As the UK’s largest fibre-only network, and its only proven wholesale challenger, we’re busy setting new standards for what digital infrastructure can and should be.
Designed from scratch for the internet, our network is greener, more reliable and ready for the future. The products we provide over it not only lead the market on speed, value and service, they help businesses to innovate, provide entire communities with a better foundation for their digital lives and support economic growth, locally and nationally.
What does that mean for you? The opportunity to make internet connections (and daily life) a whole lot better, for a lot of people!
Joining us as a Principal Application Developer – Inventory Management Ecosystem (IME)
Are you ready to shape the future of software delivery in a fast-paced, DevOps-driven environment? We’re looking for a Principal Application Developer to lead the technical vision and development of our Inventory Management Ecosystem (IME), ensuring it supports scalable, resilient, and innovative network and service management.
You’ll receive a competitive salary, a performance-related bonus, and a range of benefits to support your financial, physical, and mental wellbeing.
This is some of what you can expect to be doing:
Leading the design and development of scalable software solutions within the IME Release Train
Providing technical leadership and mentorship to developers, fostering a culture of learning and innovation
Collaborating with Enterprise and Solution Architects to translate architectural designs into actionable development plans
Driving improvements in code quality, testing, and development processes using Agile and DevOps principles
Working closely with internal teams and external partners to ensure seamless integration and delivery of third-party systems
Supporting the reduction of technical debt and introducing new development processes to improve efficiency
Maintaining strong relationships with architecture, QA, and operations teams to ensure high-quality, reliable software delivery
What you’ll bring to the role
You’ll bring deep technical expertise, a passion for clean, scalable code, and a collaborative mindset. You’ll also have:
Proven experience in PHP or Python development, with strong knowledge of frameworks like Laravel and design patterns such as MVC
Experience working with microservices, Apache Kafka, and event-driven architecture
A track record of mentoring developers and leading technical initiatives in Agile environments
Familiarity with DevOps practices, CI/CD pipelines, and tools like Git, PHPUnit, or PyTest
Strong communication and stakeholder engagement skills, with the ability to influence and collaborate across teams
A continuous improvement mindset and a passion for staying ahead of emerging technologies
Diversity, Inclusion & Belonging
We’re a Times Top 50 Employer for Gender Equality. We’re endorsed by WORK180 and we’re a partner of Diversifying. We have pledged our commitment to the Armed Forces Covenant and we’re a Disability Confident Employer. Working together with our Employee Networks, we’re wholly committed to ensuring that our people’s voices are heard, and that everyone feels a sense of belonging and pride to be a part of CityFibre. If you’d like to explore our culture and values, check out The CityFibre Way.
What you can expect from us
We want to offer you all the support you need to thrive inside and outside of work. This means giving you the tools to grow your career with us, as well as a comprehensive benefits package that you can adapt to your lifestyle. This includes 25 days annual leave, a day off on your birthday, a day off to support a charity or organisation of choice, a range of wellbeing and savings initiatives including private medical insurance, and supportive family friendly and menopause policies.
