About PureFacts Financial Solutions

PureFacts is the leader in the Revenue Performance Management category for wealth and asset management firms. The PureRevenue™ Platform helps organizations maximize revenue potential by connecting pricing, billing, compensation, advisor behavior, and AI-powered intelligence within a single Revenue Book of Record. By transforming fragmented revenue processes into a coordinated growth system, firms gain greater visibility, stronger pricing discipline, improved revenue capture, and more effective advisor alignment. The result is faster organic growth, improved profitability, and increased enterprise value. For more than 25 years, PureFacts has helped leading financial institutions turn revenue from an operational process into a strategic advantage.

At PureFacts, we are building an AI-native platform and company. We embed AI, intelligent automation, and agentic workflows across our products and operations to detect anomalies, surface insights, streamline repetitive work, and support faster, better decision-making. In a highly regulated industry, we believe AI must be practical, governed, and auditable—amplifying human expertise while helping our teams and clients focus on higher-value, strategic work.

About the role

The AI Engineer (LLM/Agent) will own the conversational layer that describes Purefacts’ ML model outputs to end users, develop a “Revenue Assistant” Agent from R&D through to prototype, and design context architecture grounded in client-specific pricing data. Builds evaluation and safety frameworks. This role sits at the intersection of machine learning, software engineering, and product, focusing on building intelligent systems that can reason, automate workflows, and augment human decision-making.

You will play a key role in advancing PureFacts’ AI-first strategy, developing AI-powered copilots, agents, and automation tools that reduce manual work, improve productivity, and deliver meaningful client value.

• 6-8+ years of total back-end software engineering experience
• Deep, hands-on experience building with agent frameworks (e.g., Microsoft Agent Framework, Google ADK, LangGraph, etc.), including designing custom orchestration patterns beyond out-of-the-box templates
• Demonstrated ownership of evaluation frameworks and pipelines and design of deterministic guardrails/safety controls in regulated or compliance-sensitive contexts
• Experience in SaaS, fintech, or other data-driven, regulated environments strongly preferred

Technical Skills

• Expert-level Python (required)
• Deep experience with:
• • LLM APIs (OpenAI, Azure OpenAI, Anthropic, etc.), including cost/latency tradeoffs at scale
  • Agent development frameworks (LangChain, LlamaIndex, LangGraph, or similar)
  • API and microservices architecture, including integrating LLM and ML model components into larger systems
  • Data processing (SQL, Python data libraries) and pipeline design for both retrieval-quality data and model training data
• Solid working knowledge of:
• • Vector databases and embedding strategies (selection, tuning, hybrid search)
  • Cloud platforms (AWS, Azure), including deployment and scaling of AI/ML workloads

AI, Agent & ML Model Expertise

• Proven experience architecting and shipping:
• • Retrieval-Augmented Generation (RAG) systems at production scale
  • Multi-step agent workflows with error handling and recovery
  • Tool-using agents and end-to-end automation systems
• Strong, applied understanding of:
• • LLM limitations, failure modes, and optimization techniques (prompt design, fine-tuning vs. RAG tradeoffs, latency/cost optimization)
  • Evaluation methods for generative AI (offline eval sets, human-in-the-loop review, regression testing for prompt/model changes, model performance monitoring)
  • Safety and guardrail design appropriate to regulated environments (PII handling, hallucination mitigation, model bias/fairness checks, audit trails)
