Senior AI Test Engineer

This is a remote position.

Location: Remote

Alternative Path is looking for a Senior AI Test Engineer to lead quality assurance on a client engagement with a leading financial data and analytics company that has built AI agent systems (chatbots, RAG-based research/report generation, MCP-based tool-calling agents) on top of its proprietary datasets for its own clients. This is a senior, client-facing role: you'll own the test strategy for these systems end-to-end, working directly with the client's engineering team to validate accuracy, reliability, and safety before these agents reach financial industry end-users — where hallucinations or bad data retrieval carry real business risk.

This is not conventional QA. You'll be building evaluation frameworks and datasets, running systematic evals, and defining quality bars for non-deterministic, LLM-driven systems operating over complex financial data.

• Own the test and evaluation strategy for the client's AI agent systems — chatbots, RAG-based research/report generation, and MCP-based tool-calling agents
  
• Design and build eval suites covering accuracy, groundedness/faithfulness to source data, task completion, latency, and safety
  
• Build and curate golden datasets reflecting real client use cases and financial-data edge cases (ambiguous queries, stale data, conflicting sources, numerical precision)
  
• Use eval/observability tooling such as LangSmith (or equivalents — Ragas, DeepEval, Braintrust, Langfuse, PromptFoo) to trace, score, and monitor agent runs
  
• Define and track RAG-specific metrics (retrieval precision/recall, hallucination rate, citation/source accuracy) — critical given the systems sit on top of financial datasets where correctness is non-negotiable
  
• Evaluate MCP-based tool-calling behavior — correct tool selection, multi-step task execution, failure handling
  
• Design regression testing so prompt, model, or data-pipeline changes don't silently degrade quality
  
• Run structured red-teaming for hallucinations, prompt injection, and unsafe/incorrect financial outputs
  
• Act as the primary quality point of contact with the client's engineering stakeholders — translating findings into clear, actionable risk assessments
  
• Mentor/guide any junior QA resources staffed onto the engagement as it scales
  
• Build automation to integrate evals into CI pipelines where feasible
  

Must-haves

• 3+ years in software QA/testing, with hands-on senior-level experience evaluating LLM-based or agentic AI systems (not just traditional QA)
  

• Direct experience with eval frameworks/tools — LangSmith strongly preferred; also acceptable: Ragas, DeepEval, PromptFoo, Braintrust, Langfuse
  
• Strong understanding of RAG architecture and how to independently evaluate retrieval quality vs. generation quality
  
• Practical familiarity with MCP (Model Context Protocol) or comparable agent tool-calling frameworks
  
• Strong Python skills for building test harnesses, scoring pipelines, and automation
  
• Experience designing evaluation approaches for non-deterministic systems (probabilistic scoring, not binary pass/fail)
  
• Comfortable working directly with client engineering teams — strong communication, able to explain quality risk to both technical and business stakeholders
  
• Prior experience in a client services / consulting QA environment (this is a client-facing engagement, not an internal product team)
  

Nice-to-haves

• Experience testing AI systems in fintech, capital markets, or data/analytics domains
  
• Familiarity with financial data accuracy/compliance considerations (numerical precision, source traceability, audit trails)
  
• Exposure to LLM red-teaming/safety evaluation practices
  
• Experience with browser-automation agent testing (Playwright or similar)
  

The client's end-users rely on these agents for financial research and decision-making — the cost of a hallucinated number or a wrong source is high. You'll be the senior technical authority ensuring these systems are trustworthy before they ship, working at the intersection of AI evaluation and financial-data correctness.
