Who we are Subtotal is a fast-growing, seed-stage startup connecting shoppers, brands, and retailers. Our platform lets shoppers link their retail accounts (Amazon, Walmart, Target, and more) and share their purchases with the brands they buy from, so those brands can finally see what their customers are buying across retail. We're early, building fast, and looking for a Software Engineering Intern who wants to work across a wide range of areas and learn from great engineers tackling novel problems. The role This is a hands-on engineering role on a small team that ships often. You'll build real product alongside our engineers and founders. That includes integrations with major retailers and other software providers, internal systems that automate everyday work, and apps shoppers and brands use directly. Your priorities and the tools you use will change frequently, and we want someone who's energized by that. What you'll do Build autonomous systems: Design and ship systems that handle routine work on their own, like keeping shoppers' retail connections healthy. Bring in new technology: Keep a pulse on new tools, models, and techniques as they come out, and figure out where they give us an edge. Own projects end to end: Take a problem from rough idea to production, then keep improving it based on what you learn. What we're looking for Above all, a real eagerness to learn: you love picking up new skills and want to get better every week Currently pursuing a degree in computer science, computer engineering, or a related field Excitement about building autonomous systems that work without hand-holding A habit of trying new tools as soon as they come out and figuring out how to put them to use A preference for shipping and iterating over planning in the abstract Strong problem-solving skills and the judgment to know when something is ready to ship Hungry, self-directed, and comfortable with ambiguity Nice to have Experience with APIs, data pipelines, or third-party integrations Experience building agents Interest in commerce, retail, or marketing tech Details Hours: Full or part time Location: Primarily remote with regular in-person onsites. We may move to a hybrid model in the near term. Preference for candidates in New York City or Utah. What we offer $20-$30/hr Real ownership over work that ships to production Direct mentorship from our engineers and founders A small, low-ego team If you're eager to learn from great engineers and see your work ship, we'd love to hear from you.
