AJ Bell Tech Stack

Financial Services Manchester 1,001–5,000 employees Public Company

AJ Bell operates a multi-asset investment platform (SIPPs, ISAs, dealing accounts) with £103.3 billion in assets under administration, built on a modern polyglot stack: Go, TypeScript, React, Vue, PostgreSQL, Kubernetes, and AWS. Engineering is hiring most aggressively, and the project list reflects dual pressure—modernizing legacy platforms while launching a mobile-first investment app and next-generation core platform—a pattern matched by pain points around FCA CASS compliance, operational resilience, and security posture during infrastructure migration.
