Maintain, extend, and modernise legacy Java and Python codebases that form the backbone of firm infrastructure. Communicate technical strategies, trade-offs, and delivery progress clearly to non-technical stakeholders, including senior leadership. Requirements 3-5 years of professional software engineering experience with a strong track record of delivering production systems. Demonstrated production experience building and deploying RAG architectures, MCP servers, and/or LLM-based agent systems, not just prototypes or proof-of-concept work. Deep proficiency in Python and Java, with hands-on experience maintaining, extending, and modernising legacy codebases in both languages. Strong SQL skills with experience querying complex relational data models; SQL Server experience is a plus. Excellent communication skills, with experience presenting technical work and roadmaps to non-technical business stakeholders. A Bachelor's degree in Computer Science from a recognised university.
