Senior Data Analyst / Data Engineer

We are now looking for a Senior Data Analyst / Data Engineer to help us stabilise, simplify, and evolve our data capability-someone who can both get their hands dirty today and shape where we go next.

This is not a “plug-and-play” analytics role. It’s a chance to build foundations, influence how decisions are made, and work directly with the CEO to surface the real problems-not just report numbers.

What You’ll Be Responsible For

1. Make data usable, trusted, and visible * Take ownership of data quality, structure, and accessibility * Identify and fix the biggest issues: data cleanliness, definitions, consistency, and single points of failure * Create clear, reliable views of the business that people actually understand and use

2. Turn complexity into clarity * Translate complex, messy datasets into simple, digestible insights * Build dashboards and analyses that tell a story, highlight trade-offs, and make problems visible * Help non-technical stakeholders understand what matters, what’s broken, and what to do next

3. Partner directly with the CEO * Work closely with the CEO to frame the right questions and reveal underlying operational and commercial issues * Support decision-making with evidence, not noise * Be confident challenging assumptions when the data says something uncomfortable

4. Be hands-on while shaping the future * Roll up your sleeves to write SQL, build pipelines, fix broken reporting, and create interim solutions * In parallel, define a clear vision for the future: tooling, architecture, data ownership, governance, and how analytics should support the business as we scale

5. Reduce risk and dependency * Help move us away from single-person dependency * Document data logic, definitions, and processes * Create a more resilient, shared approach to data across teams

Experience & Skills

• Strong experience as a Senior Data Analyst, Analytics Engineer, or Data Engineer (3+ years)
• Comfortable working in imperfect, fast-moving environments
• Excellent SQL skills and experience working across multiple data sources
• Experience building data models, reporting layers, and dashboards used by senior leadership
• Confident with modern data stacks (e.g., Snowflake, dbt, Power BI, Airbyte-exact tools matter less than mindset)

Way of Working

• Calm, structured, and resilient-especially when things are messy
• Able to prioritise ruthlessly: not everything needs fixing at once
• Strong communicator who can explain data clearly, say “this is good enough for now,” and push back when needed
• Comfortable operating without a detailed playbook

Pulled from the full job description

• Free parking
• Company pension
• On-site parking, * You see messy data as a problem to be solved, not a reason to disengage
• You enjoy building foundations, not just polishing finished products
• You care about impact, not just outputs
• You’re as comfortable in a leadership conversation as you are writing code

What Success Looks Like

• The CEO and leadership team have clear, trusted views of the business
• Data conversations shift from “Can we trust this?” to “What should we do about this?”
• Key risks, bottlenecks, and trade-offs are visible early
• Data is no longer a single point of failure
• There is a credible, realistic roadmap for how data will support the business long-term
