Job Description

I’m partnering with an innovative client scaling their AI capability across finance and back-office operations. We’re looking for Senior AI Engineers with strong software engineering fundamentals and hands-on experience in agentic workflows, RAG pipelines, and enterprise-grade GenAI solutions.
You’ll work on automation solutions across Accounts Payable, Reconciliations, document processing, and exception handling, developing AI agents and workflows that materially uplift operational efficiency. This is a highly progressive environment moving quickly on new AI capabilities as they emerge.

What You’ll Do
  • Scope, design, and deliver enterprise-ready AI solutions across finance workflows
  • Build and implement agentic workflows, including:
    • Future state planning
    • Tool/function calling
    • Guardrails + safety controls
    • Multi-agent handoffs
    • Memory/state management
  • Develop RAG workflows, optimising chunking and retrieval strategies for high-quality performance
  • Build and deploy AI agents for invoice matching, AP triage, reconciliation logic, exception handling, and document understanding
  • Integrate AI components into existing finance systems and back-office environments
  • Use guardrails and safety frameworks to ensure reliable, safe AI behaviour at scale
  • Run discovery sessions, scope PoCs/MVPs, communicate risks/assumptions, and collaborate with stakeholders
  • Write clean, scalable, production-grade Python or TypeScript code
  • Work end-to-end: data ingestion → orchestration → model integration → deployment
What We’re Looking For
  • Proficient in Python and/or TypeScript/Node.js
  • Strong experience with embeddings, vector databases (Pinecone, pgvector, Weaviate), RAG pipelines, and chunking strategies
  • Experience with agentic workflows using OpenAI Agents SDK and/or Google ADK
  • Comfortable with LLM observability: tracing, evaluation, monitoring
  • Familiar with FastAPI, Next.js, LangGraph, or similar frameworks
  • Experience with cloud platforms (AWS, Azure, GCP)
  • Understanding of authentication/security (JWT, OAuth)
  • Knowledge of OpenAI, Anthropic, Databricks, MLflow or similar tools
  • Excellent communication skills and the ability to work directly with stakeholders
  • Passion for emerging AI technologies and building practical, scalable automation
Why Join
  • Work on cutting-edge GenAI/agentic systems
  • Fast-moving, innovative engineering environment
  • Build real solutions that create measurable impact on finance operations
  • Opportunities for rapid learning and technical growth
