Staff Full Stack Engineer (PHP+Flutter), Smart Fridges
About the role
About CookUnity:
Food has lost its soul to modern convenience. And with it, it has lost the power to nourish, inspire, and connect us. So in 2018, CookUnity was founded as the first-of-its-kind platform that connects the world with the source of truly great food: chefs. Today, CookUnity delivers 50 million meals a year from the industry’s best chefs to homes all over the country. Fresh. Ready-to-eat. And crafted with the passion that nourishes body and soul.
Unwilling to stop there, CookUnity is expanding beyond delivery to become an ever-innovating marketplace focused on our singular mission: empower Chefs to nourish the world.
If that mission has you hungry in more ways than one, you’ve found the right job posting.
About The Team:
Fraîche is CookUnity’s smart fridge solution, bringing fresh, chef-made meals, drinks, and snacks into offices across the U.S. With a mobile app, IoT-enabled fridges, and seamless backend operations, Fraîche is reshaping how people eat at work — making healthy, delicious food as easy as opening a fridge.
As part of CookUnity for Business, our team is scaling rapidly. To get there, we’re expanding the Fraîche tech team with a critical hire: a Staff Full Stack Engineer who will own the architecture, product development, and engineering culture behind our smart fridge platform.
This role blends product thinking, hands-on coding, and leadership. You’ll work closely with our B2B Engineering Managers, Product Managers, Backend and Frontend Engineers to deliver a robust, scalable experience that bridges physical and digital food experiences.
Responsibilities:
- Own the Full Stack: Lead the development of features across mobile apps, internal tools (PWAs), APIs, and services — ensuring end-to-end quality and performance.
- Guide Tech Decisions: Define and implement best practices across the stack. Architect solutions that support our rapid growth and physical infrastructure (smart fridges, inventory systems, customer flows).
- Lead & Mentor: Support a growing team of engineers, starting with our Front-End & Back-End Engineers. Help define team rituals, code quality standards, and onboarding practices.
- Connect with IoT: Work on backend services that communicate with our fleet of connected fridges in real-time. Ensure uptime, automation, and traceability at scale.
- Drive Product Delivery: Collaborate with Product, Design, and Operations to scope, prioritize, and ship improvements that delight users and streamline operations.
- Balance Execution & Vision: Be hands-on with code while contributing to long-term technical strategy and integration with the broader CookUnity B2B platform.
- Collaborate Cross-Team: Coordinate with CookUnity’s central B2B team (React, Node, NestJS) to align on architecture, shared services, and platform migration strategy.
Our Current and Evolving Stack:
We leverage a modern cross-platform stack to power Fraîche’s smart fridge platform, and we’re always adapting to use the best tools for the job. Currently, our platform runs on a mix of proven and cutting-edge technologies, and we have big plans to evolve it in the next year:
