Senior/Staff Software Engineer, React Native

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With fragmented records and outdated tools, business owners can’t easily see what’s working — let alone prove viability to a lender, partner, or the next generation.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. As one of our first engineers focused on our mobile app, you’ll help drive our technical decisions and influence our product direction for years to come, with the goal of making agriculture more sustainable and profitable.

For many farms, poor broadband connectivity and little time in the office (if there is an office) means that the smartphone is the fastest computer available. Being able to run your business from the tractor, while at the farmer’s market, or in the field, is incredibly empowering. As a mobile engineer, your work will enable our engineers to be highly productive by emphasizing sharing business logic between platforms and crafting a high quality design system. These investments are being used today by our engineers to launch features to four platforms at a time (desktop web, mobile web, Android, iOS).
