Shared Goal: Empowering Data-Driven Business Decisions

Ultimately, both roles serve the same master: the business. When analysts and engineers share a common understanding of organisational goals, their collaboration becomes a powerful engine for growth. The engineer provides the reliable fuel (data), and the analyst navigates the vehicle (insights) toward the strategic destination.

Structure your team: What to recruit for

As a data leader building a team for 2026, your hiring strategy must evolve beyond traditional skill checks. For Data Analysts, look past candidates who only list SQL and Tableau. Prioritise those who demonstrate exceptional business acumen and curiosity. Ask them to walk you through a project where they influenced a business decision, not just produced a report. The key differentiator is their ability to translate data into a strategic narrative. Screen for candidates who are conversant in the potential of generative AI and can articulate how they would use it as a tool for deeper, faster inquiry.

When recruiting Data Engineers, move beyond legacy ETL processes. Your top candidates must be cloud-fluent, with demonstrable projects on AWS, GCP, or Azure. Probe for experience with infrastructure-as-code (e.g., Terraform) and containerization (Docker, Kubernetes). The modern engineer thinks in terms of automation and scalability. Look for a “DataOps” mindset: someone who values testing, monitoring, and iterative improvement. A critical, often overlooked, trait is their ability to collaborate with analysts; ask how they have worked with stakeholders to understand data requirements and ensure usability. The best engineers are not just coders; they are architects who understand their end-users.
