About this role
Wanstor is an award-winning Managed IT Services provider helping ambitious organisations use technology to achieve better business outcomes — securely, efficiently, and at scale. Established in 2002, we deliver end-to-end technology services spanning managed IT support, cloud, infrastructure, networking, security, communications, and AI adoption services. This is a brilliant opportunity for a Senior Network Engineer who wants more than a traditional MSP engineering role. You’ll join Wanstor as part of a small, dedicated IT team supporting one of our key customers , spending three days a week on-site at their offices in The Shard . It’s an impressive environment to work in, but more importantly, the role gives you the chance to get genuinely close to the customer, understand their technology estate and have real ownership over how their network evolves. Rather than moving between customers or simply picking up tickets, you’ll become a trusted technical presence within the customer , taking ownership of complex networking issues, improvements and projects. You’ll work across BAU and project activity, helping to design, implement and improve their network environment while spotting opportunities to make things more resilient, secure and effective. You’ll still have the backing, expertise and wider technical community of Wanstor behind you, but with the autonomy and ownership that comes from being embedded with a customer . It’s a great fit for someone who enjoys being hands-on technically but also wants visibility, responsibility and influence — someone comfortable speaking directly with stakeholders, taking a problem away and owning it through to resolution, and playing a leading role in network projects rather than simply being handed individual tasks.
