Just Group plc Tech Stack

UK retirement specialist delivering annuities, equity release, and de-risking solutions

Financial Services Reigate, Surrey 1,001–5,000 employees Public Company

Just is a FTSE-listed financial services group focused on retirement income and longevity risk management. The tech stack reveals a hybrid enterprise architecture — Azure cloud infrastructure paired with Python, SQL, and modern web frameworks (Next.js, React) — suggesting active modernization alongside legacy financial systems (Bloomberg, Refinitiv, SQL Server, Dynamics 365). Active projects around medallion-architecture data transformation and a real-time behavioural insights system signal a push toward data-driven product decisions, while pain points around operational risk, key person dependencies, and stress-testing accuracy point to a company scaling governance and analytics capabilities ahead of regulatory demands.
