This role may require occasional work outside standard business hours to accommodate client time zones and up to 15% travel to client sites, including occasional overnight and multi-day engagements.
Applicants must have, and maintain, the right to work in the United Kingdom from the first day of employment. Please note that visa sponsorship is not available for this role.
What You'll Do
Build AI-powered agents and tools end-to-end: identify the problem with clients and domain experts, prototype quickly, evaluate rigorously, and ship to production
Design and implement LLM integrations including prompt engineering, function calling, structured outputs, and retrieval-augmented workflows
Define evaluation criteria and build test harnesses for AI systems where correctness is ambiguous and domain-specific
Work directly with clients to understand their workflows, validate AI behavior, and iterate toward production quality
Partner with core engineering teams to generalize client-specific work into product features
Contribute to shared AI infrastructure (agent frameworks, tool integrations, deployment pipelines)
Monitor and maintain production AI systems with attention to reliability, cost, and performance
Who You Are
Prior professional software engineering experience
Professional experience with Python (the team's primary language)
Experience working with LLM APIs (Claude, GPT, or similar) including function calling and structured outputs
Comfort with SQL for data exploration and building data-grounded AI workflows
Experience with AI-assisted development tools (Claude Code, Codex, or similar)
You've built something from zero to one. You're drawn to figuring out what to build, not just building what's specified.
A bias for action. You ship quickly, learn from feedback, and iterate.
You see projects through from prototype to production and care about what the client experiences, not what the code does
BS/MS in Computer Science, Mathematics, or another quantitative field, or equivalent experience
Nice to Have
Experience building agentic systems (multi-step tool use, agent orchestration, durable workflows)
Experience with additional backend languages (Java is valuable in our environment)
Familiarity with financial data (portfolios, transactions, securities, accounting)
Exposure to cloud infrastructure (AWS) and container-based deployments
Experience with evaluation frameworks or methodologies for measuring AI system quality
