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 CookUnity B2B is one of the company's fastest-growing divisions, scaling across four verticals — Bulk, Smart Fridge, Healthcare, and Partnership — with a bold H2 2026 north star of $44M in revenue and 120% retention rate. Our engineering mission is equally ambitious: converge two acquired platforms into a single CookUnity codebase. B2B is the clearest example of that journey in the company — two legacy stacks, two acquired companies, converging into one. It's a high-ownership environment where engineers build at the intersection of logistics, IoT, and consumer software, with computer vision and AI-driven ordering systems already on the near-term roadmap. If you thrive on hard problems, real business impact, and a small team where your work ships immediately — this is the role for you. The Role • Lead the design and implementation of full-stack features across our B2B platform, working directly with product and operations leadership. • Drive the convergence of multiple legacy stacks into the core CookUnity codebase, making key architectural decisions along the way. • Automate and simplify operationally complex processes — from smart fridge inventory management to healthcare meal delivery workflows. • Maintain and scale our AWS infrastructure to support rapid vertical growth. • Mentor engineers across the team and contribute to raising the technical bar. • Be hands-on and build products used by thousands of corporate customers from day one. Our Current Stack: Languages: Java, JavaScript, TypeScript Frameworks: ReactJS, NestJS Infrastructure: AWS, Kubernetes, MySQL Methodology: Agile / Service-Oriented Architecture Responsibilities • Ensure the platform is scalable, reliable, and efficient across all B2B verticals. • Identify and address technical debt and performance bottlenecks proactively. • Own the design and implementation of platform features within our JavaScript/Java stack that engage customers and drive meaningful business outcomes. • Iterate on new and existing features to improve user experience, performance, and reliability. • Actively drive the adoption of strong software architecture, engineering best practices, and emerging technologies. • Lead and participate in code reviews; mentor engineers across experience levels. • Contribute technically by being a hands-on coder, removing roadblocks, and resolving technical issues end-to-end. • Partner with Product, Operations, CX, and other teams to continuously refine and improve our platform in an agile environment. • Support the on-call rotation to help the business run 24/7 • Contribute to doc
