Join us and you'll be part of a team that stays curious, positive and focused on making life easier for our customers and each other. We're investing in the future of connectivity, from expanding next-generation 5G to exploring satellite-supported solutions that help reach rural communities and hard-to-connect places. You'll work with people who back good ideas and give you plenty of room to grow. So if you're looking for a place where you can feel supported, trusted and genuinely valued, you'll feel right at home here.

- Proficiency in using bug-tracking tools such as JIRA to log, track, and manage issues effectively across teams and projects
- Strong appreciation of operational real-world customer maintenance scenarios
- Experience reviewing and analysing Digitmap/Dial Plan and MTA configuration templates
- Experience of Altiva telephony/network call flow analysis tools
- Familiarity with Jenkins and the Groovy scripting language
