AI Engineer

If you have experience building and scaling multi-agent systems, we would love to speak with you. We just raised funding from Lightspeed and are currently assembling a world-class team. At Epiminds, we’re creating a self-learning marketing team of over 20 autonomous agents working across data, creative, strategy, and execution — all led by Lucy, a super-agent who collaborates with human marketers like a true teammate: reaching out, listening, emailing, and even calling. Today, 17 agencies and 270 brands leverage our product to save 60% of their time. We just secured a $6 million round from Lightspeed to meet the high demand from our users. Lightspeed has also invested in Anthropic, xAI, Mistral, and other decacorns. Right now, we are focused on continuously improving Lucy and her team while also closing more deals with customers. Your role as one of the first AI engineers will be to enhance the multi-agent system that powers Lucy today. Here are some tasks that you will work on: • Creating new specialist agents • Improving our proprietary agentic framework • Training models on top of a proprietary dataset with terabytes of data • Continuing to enhance collaboration, memory, and other critical components of the system What we’re looking for: • You have experience building multi-agent systems • You possess deep knowledge and experience in developing ML/AI systems beyond merely calling an API • You are prepared to put in the effort required to build a category-defining product Why Epiminds: • We’re transforming manual marketing into an intelligent, self-evolving system. The next era won’t rely on manual execution; it will be orchestrated by autonomous AI teams that learn, create, and strategize with superhuman precision, speed, and imagination. • We’re a small, high-ownership team from Spotify, Google, and Kry, backed by investors behind Anthropic, xAI, and Mistral. We’re here to change the world—not someday, but now. The systems we build will redefine how ideas are created, how decisions are made, and how marketing itself evolves. If you want to help rewrite that future, this is where it begins. We welcome international applicants. English is our working language. Employment terms and conditions are equivalent to Swedish collective agreements.
