• Collaborative & Curious: A team player who enjoys learning, problem‑solving and contributing to a supportive engineering culture.
• Nice to Haves: Experience with Spark/EMR/Glue, dbt, OpenSearch, event‑driven patterns, or modern developer tooling.

Benefits

• Generous holiday entitlement: Start with 25 days per annum, increasing to 28 days after three years’ service, and 30 days after five years’ service, in addition to bank holidays.
• Flexible working options.
• £480 annual allowance for well‑being activities or gym memberships, with assistance available for monthly or annual costs.
