# Staff Software Engineer

About Us At algo1, we are reinventing one of the world’s most familiar experiences: the in-store grocery trip. We are building an AI-native product that understands each shopper, responds to their context in real time and makes an everyday experience less stressful, more personal and more engaging. We’re backed by leading investors and founded by two entrepreneurs: one with a track record of building companies, and the other a leader in retail data and shopper analytics. Together, they have brought together frontier AI researchers and engineers, product and strategy leaders, and senior operators from major UK and US grocery businesses. The people who join now will have an opportunity to shape the product, the engineering culture, and what algo1 becomes. The Role We are looking for a Staff Engineer to own the full-stack development of algo1’s retailer- and brand-facing product suite. You will be the primary engineering partner to our Head of B2B Product, James, turning ambitious and sometimes ambiguous product ideas into software that retailers and consumer brands rely on to create, launch, and measure campaigns. This is a product engineering role, not an infrastructure or platform
