About The Position

FIELDBOOK, a studio operated by Alloy Partners, is dedicated to creating and accelerating advantaged retail technology startups. We are seeking a Senior Full Stack Developer to help build and scale Umami.
Umami is an AI-enabled Food & Beverage innovation platform that analyzes customer reviews and consumer data to generate strategic product insights for CPG brands. We turn millions of customer reviews into actionable business intelligence — combining machine learning, consumer data, and a brand's unique advantages to take innovators from insight to innovation.
As the Senior Full Stack Developer, you will work closely with the Co-Founder/CEO and Head of Product as a core technical thought partner and the primary builder of the platform. You'll work across a sophisticated stack involving LLM APIs, complex data pipelines, automated data acquisition, and modern frontend frameworks.
Who You Are:
You take ownership — you treat the product like it's yours and don't wait to be told what needs attention
You're solution-oriented — you identify problems but show up with answers, not just concerns
You're accountable — you do what you say you're going to do, within the time you committed to
You know when to escalate and when to just solve it — you can distinguish between decisions that need leadership input and problems that have commonly acceptable solutions
You're pragmatic — you value code quality but avoid over-engineering, and you ship things that work
You thrive in small, high-trust teams where autonomy is high and process is lean
You find the work genuinely enjoyable — we're supporting food innovation, not curing cancer. Let's have fun together.
