Software Engineer (AI Focus)

At Brandback, we’re on a mission to redefine shopping with AI. Founded by experienced operators and backed by top tier investors and angels from the retail industry, we have gone from strength to strength since launching our product last year.

You'll develop AI agents that search, analyze, and take actions across the web, build intelligent pricing systems, and create LLM-powered applications at scale. This is a hands-on engineering role where you'll ship working systems, not just models or pipelines. As an early team member, you'll have significant autonomy and impact, working directly with founders to shape our AI strategy.
