Senior AI Engineer

About Us Fieldguide is establishing a new state of trust for global commerce and capital markets by automating and streamlining the work of assurance and audit practitioners—specifically in cybersecurity, privacy, and financial audits. We build software for the people who enable trust between businesses. We're based in San Francisco, CA, and built remote-first. We're backed by Goldman Sachs Alternatives, Bessemer Venture Partners, 8VC, Floodgate, Y Combinator, and more. Over 50 of the top 100 accounting and consulting firms trust Fieldguide to power mission-critical work. About the Role Fieldguide is building AI agents for the most complex audit and advisory workflows. As a Senior AI Engineer, you'll own meaningful product areas end-to-end—designing agentic architectures, building evaluation systems, and shipping agents that professionals trust with mission-critical work. This role is for engineers who have shipped LLM-powered features in production and are ready to take the lead on complex systems while mentoring those around them. What You’ll Own Build and Ship AI Agents Design and build agentic systems that automate complex audit workflows end-to-end Translate customer problems into concrete agent behaviors and orchestration logic Orchestrate LLMs, tools, retrieval, and business logic into reliable, production-grade agent experiences Own agents across their lifecycle: delivery, reliability, performance, and observability Execute with AI-Native Leverage Use AI to accelerate design, build, test, and iteration cycles Prototype quickly, then harden systems for enterprise-grade reliability Build evaluation frameworks, feedback loops, and guardrails to improve agents over time Design prompts, retrieval pipelines, and orchestration logic that perform at scale Drive Product Impact Make clear trade-offs on what to build, cut, or skip based on customer value Partner with Product and Design to define capabilities that deliver real outcomes Stay close to customer workflows and optimize for highest-impact problems Identify capability gaps and unblock team progress proactively Mentor and Multiply the Team Raise the quality bar through code review, design feedback, and pairing Create reusable abstractions, patterns, and tooling that increase team velocity Share learnings across the team and establish engineering best practices Who You Are You’re a strong software engineer who’s built your skills for an AI-native world. These principles resonate with you: Bias to building: You move fast and resolve uncertainty by shipping AI-native instincts: You treat LLMs, agents, and automation as core building blocks Strong product judgment: You decide what matters and why—not just how to implement it Learning velocity: You learn quickly from feedback and adjust based on data Grounded optimism: You improve what's broken today and push toward what's possible next End-to-end ownership: You understand production systems and own outcomes Experience We care more about capability and trajectory than years on a resume, but most strong candidates have: 3–6+ years shipping production software in complex, real-world systems Strong command of TypeScript, Python, and Postgres Shipped LLM-powered features serving real production traffic Built retrieval pipelines and agent orchestration systems Implemented evaluation frameworks for model outputs and agent behavior Worked with vector databases, embedding models, and RAG architectures Hands-on experience with modern LLM APIs (OpenAI, Gemini, Anthropic) and agent frameworks Comfortable operating in ambiguity and taking responsibility for outcomes What Should Excite You Enterprise-grade reliability: Building systems professionals depend on Human-in-the-loop design: Knowing when to automate vs. when to surface decisions Nuanced evaluation: Audits require judgment, so feedback structures matter Explainability: Making AI outputs and reasoning transparent and trustworthy Complex domains: Navigating compliance and enterprise rigor while moving fast Shipping daily value: Delivering agent experiences customers use every day Benefits Competitive compensation with equity Comprehensive health and wellness benefits Flexible time off and work schedules Technology reimbursements 401(k) plan Twice-yearly in-person offsites across the U.S. Wellness benefits starting on your first day Our Values Fearless — Inspire and break down seemingly impossible walls Fast — Launch fast with excellence; iterate to perfection Lovable — Deliver happiness and 11-star experiences Owners — Execute and run the business with ownership Win-win — Create mutual value and earn trust for life Inclusive — Scale the best ideas with inclusive teams
