About Us

We are building the modern operating system for grocery stores, similar to what Toast has achieved for restaurants. As a Series A startup heading toward Series B, we've built everything required to run a grocery store efficiently, profitably, and at scale - from inventory management to payment processing.

After launching in January last year, we processed $156 million in payments by year-end and are on track to 10x that growth this year. Our small team of 27 (including 11 engineers) is based in San Francisco, and we're revolutionizing a massive industry that impacts everyone's daily life.

The Role

We're seeking a Staff/Senior Staff Backend Engineer & Tech Lead to join our team and help build and maintain our novel system at scale. You'll be a key player in our journey to create vertical AI applications for the grocery industry, including AI pricing coordinators, inventory managers, and marketing systems.

This role offers significant technical ownership and leadership opportunities within a fast-growing startup. You'll work with a modern tech stack and tackle some of the most interesting challenges in heterogeneous data systems while making a meaningful impact on the food supply chain.

Responsibilities

• Technical Leadership: Serve as a tech lead for significant portions of our backend systems, providing guidance and mentorship to other engineers

• System Architecture & Design: Design and implement robust, scalable backend systems for high-transaction applications

• Feature Development: Lead the backend implementation of major product features, working in cross-functional pods with client engineers, designers, and product managers

• Data Pipeline Management: Build and manage data pipelines from multiple sources and develop agentic workflows

• Cloud Infrastructure: Help maintain and optimize our secure cloud-based operating system on Google Cloud

• Cross-Functional Collaboration: Work closely with non-technical teammates and customers to define requirements and communicate complex concepts

7+ years of experience as a backend-focused IC and prior tech lead ownership (Senior/Staff level)
