Software Engineer, AI

Ambrook’s mission is to help family-run American businesses become more profitable and resilient.

From record-breaking droughts to rising input costs and unpredictable markets, operators across American agriculture and industry are navigating increasing pressure — much of it driven by a changing climate and economy. Many of the best long-term investments — like water-efficient irrigation or improved grazing rotations — support both the land and the bottom line. But even when the payoff is clear, these changes often require upfront capital and financial clarity that’s hard to come by.

With fragmented records and outdated tools, business owners can’t easily see what’s working — let alone prove viability to a lender, partner, or the next generation.

Ambrook is rebuilding the financial infrastructure that independent operators rely on.

We replace paperwork and legacy systems with modern tools for accounting, banking, invoicing and spending — built for people who spend more time in the field than in the office. Our platform gives producers the financial clarity they need to make confident investments in their land, their operation, and their future.

Our customers are the backbone of the real economy — stewards of land, labor, and legacy. When they can invest in ways that make their businesses stronger and more durable, they become a force for generational resilience across America.

We’re starting with farmers and ranchers across the country — helping them keep the family business in the family and make decisions that stand the test of time.

We’re a Series A startup backed by top investors (Thrive Capital, Dylan Field, Homebrew, Designer Fund, BoxGroup, and more) and are looking for early team members who are looking to untangle the knotted intersection between American industry, climate, and the economy.

The opportunity

Ambrook is building a world-class team to empower industrial businesses using modern AI tools. As one of our first engineers focused on AI and machine learning, you’ll help lay the foundation for how we use LLMs and intelligent systems to make messy, high-stakes financial workflows faster, smarter, and more accessible for farmers and ranchers.

We’re dealing with problems like the messy inbox problem , cleaning and categorizing transactions, summarizing financial documents, and surfacing the right insights at the right time — and we need an engineer who’s excited to build AI-powered tools that actually work in the wild.

​​We’re looking for someone who we can count on to…

• Own: Development of intelligent systems and tools that use LLMs, NLP, and heuristics to streamline bookkeeping, inbox triage, and financial workflows.

• Teach: Best practices around ML system design, evaluation, prompt engineering, and scalable AI infrastructure.

• Learn: How messy real world financial data really is - from scanned PDFs to unformatted CSVs to text-heavy emails - and how to make sense of it using language models.

• Improve: Our internal tooling and infrastructure for classification, tagging, summarization, and user-in-the-loop AI systems.

Within 1 month you'll...

• Build and ship a feature powered by an LLM - e.g., parsing a new type of paper document, or categorizing financial transactions.

• Review our current uses of AI and write up a note identifying where AI could meaningfully improve automation and accuracy.

• Collaborate with product and engineering to understand customer workflows and where AI would reduce manual pain.

Within 3 months you'll...

• Establish early foundations for evaluation pipelines, prompt management, and feedback loops to improve LLM performance over time.

• Implement or improve systems for document extraction and financial transaction tagging, using both heuristics and model-based approaches.

• Collaborate closely with design and product to make AI features feel reliable, intuitive, and helpful, not mysterious or brittle.

Within 6 months you'll...

• Architect and scale systems for automated bookkeeping and analysis using hybrid AI + rule-based systems.

• Contribute to our long-term AI strategy: which tasks to automate, how to measure confidence, and when to keep a human in the loop.

• Help build internal tooling for prompt iteration, embedding search, labeling, and retraining.

• Share learnings in a post on Ambrook Research or an open-source tool that helps others tackle similar messy real-world data problems.

About you

• You've built and shipped ML/AI-driven features, ideally with LLMs, in a product that’s in production, not just in a notebook.

• You're excited to apply language models to real-world, unstructured, often ugly datasets, and turn them into valuable product experiences.

• You're pragmatic about AI: you know when to use an LLM, when to write a regular expression, and when to ask the user.

• Bonus : Experience working with LLM APIs, prompt engineering, embeddings, vector search, or fine-tuning.

• Bonus : You've worked on products involving transactions, finance, document processing, or communications tooling.

• Bonus : Experience with Typescript, React, and Python-based ML tooling (LangChain, OpenAI SDK, Pinecone, etc.).
