Lead AI Software Engineer / Architect
AI Tech Lead / Senior Software Engineer / Software Architect
.NET | C# | Python | AI | Architecture | London (Hybrid)
Contract: £600 – £700 per day Location: London City (1–2 days per week)
Overview
We're collaborating with a well-known global organisation undertaking a major transformation of one of its core business-critical platforms.
This role offers the chance to take a leading position in modernising a legacy product, enhancing its architecture, integrating it with broader enterprise systems, and integrating AI capabilities into both the product itself and the software development lifecycle.
Rather than a full-scale rewrite, the platform will be modernised incrementally, requiring someone who can balance strategic architectural thinking with hands-on engineering. You’ll shape the future technical direction while staying engaged with the codebase.
Ideal for an experienced Tech Lead, Senior Software Engineer, or Software Architect who enjoys solving complex technical challenges and delivering modern, scalable solutions.
