Job Description

AI Engineer developing evaluation platforms and pipelines for AI agents at fintech startup. Collaborating across teams to ensure reliable AI performance and product quality.

Responsibilities:

  • Design and build a unified evaluation platform that serves as the single source of truth for all of our agentic systems and audit workflows
  • Build observability systems that surface agent behavior, trace execution, and failure modes in production, and feedback loops that turn production failures into first-class evaluation cases
  • Own the evaluation infrastructure stack including integration with LangSmith and LangGraph.
  • Translate customer problems into concrete agent behaviors and workflows
  • Integrate and orchestrate LLMs, tools, retrieval systems, and logic into cohesive, reliable agent experiences
  • Build automated pipelines that evaluate new models against all critical workflows within hours of release
  • Design evaluation harnesses for our most complex Agentic systems and workflows
  • Implement comparison frameworks that measure effectiveness, consistency, latency, and cost across model versions
  • Design guardrails and monitoring systems that catch quality regressions before they reach customers
  • Use AI as core leverage in how you design, build, test, and iterate
  • Prototype quickly to resolve uncertainty, then harden systems for enterprise-grade reliability
  • Build evaluations, feedback mechanisms, and guardrails so agents improve over time
  • Work with SMEs and ML Engineers to create evaluation datasets by curating production traces.
  • Design prompts, retrieval pipelines, and agent orchestration systems that perform reliably at scale
  • Define and document evaluation standards, best practices, and processes for the engineering organization
  • Advocate for evaluation-driven development and make it easy for the team to write and run evals
  • Partner with product and ML engineers to integrate evaluation requirements into agent development from day one
  • Take full ownership of large product areas rather than executing on narrow tasks

Requirements:

  • Multiple years of experience shipping production software in complex, real-world systems
  • Experience with TypeScript, React, Python, and Postgres
  • Built and deployed LLM-powered features serving production traffic
  • Implemented evaluation frameworks for model outputs and agent behaviors
  • Designed observability or tracing infrastructure for AI/ML systems
  • Worked with vector databases, embedding models, and RAG architectures
  • Experience with evaluation platforms (LangSmith, Langfuse, or similar)
  • Comfort operating in ambiguity and taking responsibility for outcomes
  • Deep empathy for professional-grade, mission-critical software (experience with audit and accounting workflows are not required)

Benefits:

  • Competitive compensation packages with meaningful ownership
  • Flexible PTO
  • 401k
  • Wellness benefits, including a bundle of free therapy sessions
  • Technology & Work from Home reimbursement
  • Flexible work schedules
