Job Description

Data Analyst

Behind every better decision, someone asked a better question.

Care organisations sit on more data than they use. At Tessa.Care we'd rather turn ours into something people can act on — clearer staffing choices, earlier signals, fewer decisions made on gut feel alone.

That's your work. Not dashboards for their own sake, but analysis that changes what happens next.

What you'll do

• Turn scattered data from our systems into something coherent, reliable, and worth trusting.
• Build reporting that colleagues actually open — clear, honest, and answering questions people are really asking.
• Dig into the harder questions: where capacity is going, what patterns precede problems, which improvements moved the needle and which only looked like they did.
• Work alongside care teams and management to translate a vague concern into a testable question, and the answer back into plain language.
• Help us stay sharp on data quality and privacy. In healthcare, careless handling isn't a technical issue — it's a trust issue.

Requirements

What you bring

• Solid SQL and comfort in Python or R. You know your way around messy real-world data.
• Experience building reporting in a tool like Power BI, Tableau, or Looker.
• The habit of asking why before how — you push back on the question when the question is wrong.
• The ability to explain a finding to someone who has never opened a spreadsheet, without losing the nuance.
• Affinity with healthcare data, or the curiosity to get there fast. Familiarity with AVG/GDPR in a care context is a real plus.
