Build the global data backbone for AI and workforce intelligence as a Data Engineer at HeadFirst Group

Do you want to build scalable data platforms that power AI, analytics, and intelligent workforce solutions on a global scale? Are you excited by modern Databricks environments, cloud-native engineering, and the opportunity to help shape the future of AI-enabled platforms?

As a Data Engineer on the Global Data & AI Team at HeadFirst Group & Impellam Group, you will play a key role in building and scaling the data infrastructure that underpins our international Workforce-as-a-Service (WaaS) strategy. You will work on our internally developed Headless Data Architecture (HDA): a scalable, API-first lakehouse platform built on Azure Databricks, Delta Lake, and Unity Catalog. This platform supports analytics, AI workloads, and intelligent workforce solutions across Europe, North America, and APAC.

What makes this role unique? You won't be joining a traditional data team focused solely on reporting or ETL. You'll help build a modern global data platform where data engineering, AI enablement, and platform scalability come together. You'll work with modern technologies, AI assisted development tools, and an international engineering team that is actively shaping the next generation of workforce intelligence.

As a Data Engineer, you are responsible for designing, building, and optimizing scalable, production ready data pipelines within our global lakehouse ecosystem. You help create scalable and reusable data products that power analytics, AI, and operational intelligence. You will contribute directly to the further development of our Headless Data Architecture (HDA), where governance and scalability are embedded into every layer of the platform.

In this role, you will work closely with ML/AI Engineers, Platform Engineers, Cloud Engineers, and stakeholders across Europe, the UK, the US, and APAC. Together, you will help shape a modern cloud data platform that enables teams to exchange, govern, and leverage data efficiently. You will join a growing international engineering team with significant influence over platform decisions, engineering standards, and the future direction of the platform.
