Put simply, we build software for the people who enable trust between businesses.\nWe’re based in San Francisco, CA, but built as a remote-first company that enables you to do your best work from anywhere. We're backed by top investors including Growth Equity at Goldman Sachs Alternatives, Bessemer Venture Partners, 8VC, Floodgate, Y Combinator, DNX Ventures, Global Founders Capital, Justin Kan, Elad Gil, and more.\nWe value diversity - in backgrounds and in experiences. We need people from all backgrounds and walks of life to help build the future of audit and advisory. Fieldguide’s team is inclusive, driven, humble and supportive. We are deliberate and self-reflective about the kind of team and culture that we are building, seeking teammates that are not only strong in their own aptitudes but care deeply about supporting each other's growth.\nAs an early stage start-up employee, you’ll have the opportunity to build out the future of business trust. We make audit practitioners’ lives easier by bringing together up to 50% of their work and giving them better work-life balance. If you share our values and enthusiasm for building a great culture and product, you will find a home at Fieldguide.\nAbout the Role\nFieldguide is building AI agents for the most complex audit and advisory workflows. We're a San Francisco-based Vertical AI company building in a $100B+ market undergoing rapid transformation. Over 50 of the top 100 accounting and consulting firms trust us to power their most mission-critical work. We're backed by Bessemer Venture Partners, 8VC, Floodgate, Y Combinator, Elad Gil, and other top-tier investors.\nAs a Senior AI Engineer, Quality, you will own the evaluation infrastructure that ensures our AI agents perform reliably at enterprise scale. This role is 100% focused on making evaluations a first-class engineering capability: building the unified platform, automated pipelines, and production feedback loops that let us evaluate any new model against all critical workflows within hours. You'll work at the intersection of ML engineering, observability, and quality assurance to ensure our agents meet the rigorous standards our customers demand.\nWe're hiring across all levels. We'll calibrate seniority during interviews based on your background and what you're looking to own. This role is for engineers who value in-person collaboration at our San Francisco, CA office.\nWhat You'll Own\nMeasurable AI Agents\nDesign and build a unified evaluation platform that serves as the single source of truth for all of our agentic systems and audit workflows\n\nBuild 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\n\nOwn the evaluation infrastructure stack including integration with LangSmith and LangGraph.\n\nTranslate customer problems into concrete agent behaviors and workflows\n\nIntegrate and orchestrate LLMs, tools, retrieval systems, and logic into cohesive, reliable agent experiences\n\nRapid Model Evaluation\nBuild automated pipelines that evaluate new models against all critical workflows within hours of release\n\nDesign evaluation harnesses for our most complex Agentic systems and workflows\n\nImplement comparison frameworks that measure effectiveness, consistency, latency, and cost across model versions\n\nDesign guardrails and monitoring systems that catch quality regressions before they reach customers\n\nAI-native engineering execution\nUse AI as core leverage in how you design, build, test, and iterate\n\nPrototype quickly to resolve uncertainty, then harden systems for enterprise-grade reliability\n\nBuild evaluations, feedback mechanisms, and guardrails so agents improve over time\n\nWork with SMEs and ML Engineers to create evaluation datasets by curating production traces.\n\nDesign prompts, retrieval pipelines, and agent orchestration systems that perform reliably at scale\n\nOwnership of Quality and Large Product Areas\nDefine and document evaluation standards, best practices, and processes for the engineering organization\n\nAdvocate for evaluation-driven development and make it easy for the team to write and run evals\n\nPartner with product and ML engineers to integrate evaluation requirements into agent development from day one\n\nTake full ownership of large product areas rather than executing on narrow tasks\n\nWho You Are\nYou are an engineer who believes that evaluations are foundational to building reliable AI systems, not a nice-to-have. The following operating principles should resonate with you:\nEvaluation-first mindset: You understand that for an AI company, not being able to evaluate a new model quickly is unacceptable\n\nAI-native instincts: You treat LLMs, agents, and automation as fundamental building blocks and parts of the craft of engineering\n\nData-driven rigor: You make decisions based on metrics and are obsessed with measuring what matters\n\nProduction-oriented: You understand that evaluations must work on real production behavior, not just offline datasets\n\nStrong product judgment: You can decide what matters and why, without waiting for guidance, not just how to implement it\n\nBias to building: You move fast and build working systems rather than perfect specifications\n\nExperience\nWe care more about capability and trajectory than years on a resume, but most strong candidates will have:\nMultiple years of experience shipping production software in complex, real-world systems\n\nExperience with TypeScript, React, Python, and Postgres\n\nBuilt and deployed LLM-powered features serving production traffic\n\nImplemented evaluation frameworks for model outputs and agent behaviors\n\nDesigned observability or tracing infrastructure for AI/ML systems\n\nWorked with vector databases, embedding models, and RAG architectures\n\nExperience with evaluation platforms (LangSmith, Langfuse, or similar)\n\nComfort operating in ambiguity and taking responsibility for outcomes\n\nDeep empathy for professional-grade, mission-critical software (experience with audit and accounting workflows are not required)\n\nWhat Should Excite You\nAgent reliability at enterprise scale: Building systems that professionals depend on\n\nBalancing automation with human oversight: Knowing when to automate and when to surface decisions to experts\n\nProduction feedback loops: Turning real-world agent failures into systematic improvements\n\nExplaining AI decisions: Making all forms of AI outputs and agent reasoning transparent and trustworthy\n\nEvaluation for nuanced domains: Structuring data and feedback for workflows where ground truth requires expert judgment\n\nHigh-impact visibility: Your work directly enables leadership to confidently communicate AI quality to the board and customers\n\nMore about Fieldguide:\nFieldguide is a values-based company.
