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.
Key Responsibilities
Leadership & Delivery

• Lead other Implementation Engineers, helping them grow and get the most from Xfuze
• Own pre-sales, discovery, design, environment, releases, and supportability end-to-end, acting as gatekeeper for designs from other Senior Implementation Engineers
• Support estimating and sizing projects through pre-sales and delivery
• Collaborate with Client Partners and Pre-Sales on commercial aspects, and with the product team (including our Central Design Group) on technical aspects
• Make high-level design decisions with enterprise-grade architectural maturity, validating designs prior to formal review

Product Implementation

• Take a "standard first" approach, challenging requests for bespoke customisation
• Analyse, explore, and validate data with clients to understand structures and use cases
• Identify product gaps and coordinate with the platform team to resolve them
• Produce high-level designs using standard templates; scrutinise and approve low-level designs, config specs, and code
• Deliver complex implementations, including custom plugins and data model extensions, working with data engineers and platform developers
• Configure connectors (e.g., Shopify, Akeneo, Bloomreach, Optimove), workflows, and data transformations
• Create and extend Power BI dashboards using Xfuze data layers

• Contribute to commercial proposals and implementation strategy
• Understand client landscapes and use cases; advise on best practices and the right implementation path
