Full-stack Engineer

If you are a solid full-stack developer with experience in agentic systems, we would love to speak with you. We just raised funding from Lightspeed and are currently building 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 a full-stack engineer will be to build on the systems surrounding Lucy. Here are some tasks you will work on: • Implement and maintain features across the full stack: frontend, backend, and infrastructure. • Own systems end-to-end: architecture, implementation, deployment, and iteration. • Collaborate closely with the founders and AI engineers to translate capabilities into intuitive, mind-blowing user experiences. • Drive the full development lifecycle, from technical planning to production launch and post-release improvements. • Contribute to shaping our technical direction, engineering culture, and product strategy. What we’re looking for: • 3+ years of experience building and shipping full-stack products. • Proficient in modern frontend (React/TypeScript) and backend development. • Solid understanding of systems design, performance trade-offs, and scalable architecture. • Strong product sense and the ability to make well-reasoned technical decisions, knowing when to prioritize speed and when to invest in foundational work. 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.
