Expert Analysis

This position is a classic “fractional” architecture role, requiring high cognitive flexibility to move between multiple product squads. At a firm as large as L&G, the challenge isn’t just technical; it’s about creating “delegated decision-making” frameworks that allow teams to move fast without breaking the strict governance required of a global asset manager.

The role is based at L&G’s London headquarters at One Coleman Street in the heart of the City (the “Square Mile”). The office is adjacent to major transport hubs like Bank and Liverpool Street. Note: L&G is scheduled to move to a greener office at 10 Coleman Street in early 2027.
