Senior Data Engineer (AWS) London / WFH to £90k

Do you have expertise with modern data platform engineering?

You could be progressing your career in a senior, hands-on role at a well established consumer facing financial services company that help people to manage debt, as they go through a technical transformation and scale-up following recent investment.

You'll own and evolve data ingestion pipelines, including incremental migration from a legacy monolith and Oracle-based systems, dual-running and reconciliation during platform transition (12-24 month initiative) and be responsible for the ongoing ingestion from systems of record (e.g. Sage, HR systems, HubSpot) and partners with the ultimate aim of establishing a hub-and-spoke, single source of truth data architecture that supports both transition and long term scale.

Location / WFH

You'll be based in fantastic new offices in London that offer a wide range of facilities including wellness rooms and onsite gym for three days a week with flexibility to work from home twice a week.
