Principal Data Architect

A Lead/Principal Data Architect at Haefele Software is a technical leader who combines strategic thinking, deep architecture expertise, and a strong delivery mindset to help clients unlock the full value of their data. These individuals operate confidently at the intersection of business and technology—crafting secure, scalable, and high-impact data platforms using the modern Microsoft data stack.

They bring years of hands-on experience working across diverse industries, guiding teams through complex data challenges, and delivering intelligent, future-ready solutions. Their toolkit spans Azure, Microsoft Fabric, Synapse, and Power BI—and they’re just as comfortable in a whiteboarding session with a CTO as they are modelling data in a Lakehouse environment. Lead Data Architects at Haefele are not just builders—they’re advisors, coaches, and problem-solvers. They help teams adopt best practices, avoid pitfalls, and move faster with confidence. They’re critical to pre-sales, delivery, and internal capability growth, and they serve as role models for what quality technical leadership looks like.

Your journey at Haefele kicks off with full support from our staff experience team, who’ll make sure you’re fully equipped with your hardware, access, and everything else you need from Day one.

You’ll go through a series of structured induction touchpoints across your first few weeks – These include introductions to key people, our ways of working, and our internal delivery practices — all designed to help you land smoothly and start adding value confidently.

You’ll meet your direct lead, connect with your client team, and get introduced to the broader leadership team. You’ll start contributing to real work, with support from your Practice Lead and peers to guide you along the way. We’ll also help you set some initial professional goals and check in regularly to track your progress, offer feedback, and support your growth in the role.
