## Description

Lead Technical Architect (Java AWS Agentic AI) London / WFH to £130k

Do you have experience of architecting and leading the modernisation of Payments, FX or Core Banking platforms?

You could be progressing your career in an impactful role at a scale-up Tech for Good software house.

The platform enables easier money transfer to people in emerging economies, disaster and war zones that do not have access to a bank account; enabling relatives, charities, the UN and UNICEF to get money to remote communities where it is needed most using sophisticated technology.

Your role:

As the Lead Technical Architect you will collaborate with Team Leads across the business to support them with technical architecture and design on large, complex, cloud based distributed systems, ensuring best practice and a cohesive structure.

The tech stack is based on modern Java and AWS, using TDD and DevOps practices such as CI/CD; you'll seek to modernise this, designing and implementing the architecture needed to support an agentic, AI-enabled Target Operating Model, including autonomy layers, orchestration patterns and human-in-the-loop principles.

You'll provide technical and domain expertise, driving the modernisation and re-architecture of the FX, Payments and Core banking platforms and driving the adoption of Agentic AI development.
