Job description

You will own the systems that safely streamline business processes using LLMs and generative AI. You'll work on projects including:

• Improving our internal chatbot that supports customer ops
• Expanding our in‑house schema extraction pipelines for faster, more accurate document parsing automation
• Designing LLM‑driven workflows that streamline various case management workflows
• Identifying new opportunities where GenAI can radically simplify how we operate

This role blends applied AI engineering, business‑process design, and hands‑on Python development. You'll be working on problems that don't have perfect definitions, where ambiguity is normal and creativity is essential.

Responsibilities

• Build real, production GenAI systems – not demos – that directly shape how a leading fintech operates
• Work with LLMs, retrieval systems, agents, and automation pipelines on a daily basis
• Own your solutions from idea, prototype, to production deployment and monitoring
• Work in small, autonomous teams that ship fast and give you real decision‑making power
• Redesign legacy processes from scratch using AI instead of patching around them
• Bring curiosity, resourcefulness, and a desire to replace manual work with smarter systems

Qualifications

• Strong Python engineering skills, comfortable building production‑grade systems
• Hands‑on experience using LLMs in real workflows
• Ability to design, evaluate, and iterate on prompts, retrieval pipelines, and agentic flows
• Understanding of business processes and an instinct for simplifying or automating them
• Comfortable working with ambiguity, quickly testing hypotheses, and refining ideas with partial information
• Skilled at breaking poorly defined problems into structured steps and deciding when/how to bring AI into the loop
• Clear communicator who can articulate trade‑offs and influence stakeholders
