Principal Implementation Engineer

About us
Xiatech is the pioneer of Xfuze, the world’s first AI-powered composable Integration, Data Management, Analytics and Orchestration Platform that innovatively connects systems, creates a single view of data and delivers actionable insights in one cloud-native, SaaS solution. Business, technology and data teams use Xfuze to shorten time-to-insights, accelerate digital transformation, and extend the value of their legacy technology investments.

We’re a culture-first organisation and put our people at the forefront of everything we do. We believe that a great working environment leads to a happy and productive team, which is why we offer our staff the flexibility to work remotely or from our beautiful office in Fitzrovia, Central London.

The Role
We're looking for a highly motivated, independent Principal Implementation Engineer to become an Xfuze "super user", architecting and delivering end-to-end, data-driven solutions for our clients. You'll be involved from the start of each engagement: understanding requirements at pre-sales, running business analysis, building conceptual architecture through to high-level design across data, integration, and agentic AI workflows, then getting hands-on to configure the platform yourself.

You'll likely have a background in data and/or integration, an architecture and design mindset, strong communication skills, and a natural ability to lead others. Ideally you've worked on a data/integration or complex Enterprise SaaS platform within a professional services team, with a track record of delivering successful projects. Deep technical expertise everywhere isn't required, but a solid technical foundation and willingness to learn are essential. This is a broad, end-to-end role, so flexibility is key.
