Technology Supplier Relationship Manager in London

The Department

Our Technology team continues to go from strength to strength, playing a vital role in firm‑wide innovation, operational excellence, and business strategy.

Far from being a traditional support function, Technology is central to the firm’s growth agenda and is backed by strong leadership engagement and sustained investment across platforms, infrastructure, cyber security, data, AI, and digital transformation initiatives.

The Technology organisation supports a global user base across multiple international locations including the UK, UAE, Singapore, and Hong Kong, delivering business‑critical services within a highly demanding professional services environment.

The estate is substantial and complex, comprising over 350+ services operating across a predominantly cloud‑first Microsoft ecosystem, including Azure, Microsoft 365, enterprise platforms, collaboration technologies, identity services, AI‑enabled capabilities, and business‑critical legal applications.

Technology services are delivered through a globally integrated operating model, supported by a broad ecosystem of strategic suppliers, managed service providers, cloud vendors, Saa S platforms, and specialist technology partners.

These relationships are critical to ensuring stability, security, scalability, and continuous evolution of the firm’s technology landscape.

As the firm continues to modernise its technology environment, there is significant focus on improving operational maturity, governance, automation, commercial optimisation, and supplier accountability.

This includes increased investment in cloud transformation, AI‑enabled technologies, modern workplace services, cyber security, and data platforms, alongside growing emphasis on responsible AI adoption, commercial transparency, and effective management of consumption‑based technology services.

The Supplier Relationship Manager will play an important role in helping the firm maximise value from its technology investments, ensuring strategic suppliers are aligned to business priorities, operational expectations, commercial objectives, and the firm’s evolving technology strategy.
