Full-stack Developer

Super Benji is building the future of work - one where AI doesn’t replace people, but works alongside them as a true teammate.

We believe the best work happens in relationships, not spreadsheets. Yet today, too much of our time is spent on repetitive tasks that pull us away from the conversations that actually matter. That’s where Benji comes in.

Super Benji is an AI-powered sales teammate designed to help people build meaningful, high-quality relationships at scale. It researches prospects, spots the moments that matter, and crafts thoughtful, personalised outreach – all in a way that feels human, not automated. The result? Less time spent on admin, more time spent building trust, and better outcomes for everyone involved.

We’re an early-stage, fast-growing company based in Oxford, with big ambitions to redefine how modern sales works. Our team is small, ambitious, and collaborative, and we’re looking for people who want to help shape not just a product, but a new category of relational selling.
