As an AI Engineer you’ll build Fieldguide’s intelligence layer—agentic workflows architectures and evaluation systems that power enterprise-grade agents. You’ll operate at the intersection of product engineering applied AI and production systems.

• Implement agentic workflows that automate complex audit tasks

• Turn customer problems into discrete testable agent behaviors

• Integrate LLMs tools and retrieval logic into reliable agent experiences

• Monitor and maintain agents in production with a focus on reliability and performance

• Use AI tooling to accelerate how you design build and test features

• Prototype quickly and harden systems for enterprise reliability

• Build evaluations and feedback loops to improve agent outputs

• Write prompts and retrieval pipelines that perform at scale

• Work closely with senior engineers and product to scope and deliver features

• Translate customer workflows into clear engineering requirements

• Identify and surface capability gaps to improve team velocity

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're excited to use LLMs agents and automation as core tools

• Curiosity and learning velocity: You ramp quickly on new problems and technology

• Collaborative: You communicate proactively and seek feedback often

• Attention to detail: You care about quality in code and customer-facing outputs

We care more about capability and trajectory than years on a resume but most strong candidates have:

• 1–3 years shipping production software in real-world systems

• Proficiency in TypeScript and/or Python

• Some exposure to LLM APIs (OpenAI Anthropic Gemini) or AI tooling

• Familiarity with retrieval pipelines RAG concepts or vector databases is a plus

• Experience with React and Postgres is helpful but not required

• Comfortable working in ambiguity with direction from senior engineers

• 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
