• Supporting Know-How: Solid grasp of data architecture, governance and security.
• DevOps & Cloud Fluency: Practical experience with CI/CD pipelines, APIs, and cloud tooling (e.g. Azure DevOps).
• Engineering Craftsmanship: Commitment to clean, maintainable code, robust testing, graceful failure handling, and managing technical debt.
• Problem Solver: Strong analytical mindset and a skill for root-cause resolution.
• Growth Mindset: Comfortable navigating ambiguity, balancing exploration with simplification, and thriving in evolving environments.
• Impact-Driven: Passionate about turning data into business value, with a collaborative and customer-focused approach.
• Clear Communicator: Able to translate complex technical concepts for diverse audiences and engage stakeholders effectively.
• Self-Starter: Skilled at prioritising, managing time, and delivering high-quality work that drives outcomes.
• Team Player: Supportive, curious, and constructive; always ready to mentor, challenge the status quo, and build together.
