Simmons & Simmons Tech Stack

International law firm serving asset management, finance, energy, and tech sectors

Law Practice London 1,001–5,000 employees Partnership

Simmons & Simmons is a 1,000+ person international law partnership founded in 1896, headquartered in London. The firm is actively adopting GitHub Copilot and retrieval-augmented generation (RAG) while maintaining a traditional legal tech stack (iManage, Workday, Bloomberg). Hiring is concentrated in legal roles (107 of 138 open positions), with pockets of engineering (3) and product (1) — a composition that signals selective tech build rather than platform transformation. Active projects span structured transactions (debt issuances, hedge fund formation, ISDA agreements) and operational efficiency improvements, while recurring pain points center on meeting volatile client demand and staffing constraints.
