About the Role We are looking for an AI-native full stack engineer to join one of the leading software companies within our portfolio. Our platform powers mission-critical workflows for organizations that depend on it every day, and we are actively expanding it through AI capabilities and entirely new software products.

You will work across both an established production platform and new AI-driven products. We are especially interested in people who see themselves as builders. The best candidates are curious, ambitious, and constantly experimenting with new tools. They build side projects, explore AI models, and look for opportunities to improve systems rather than waiting for instructions. You will work closely with a senior engineer who has built and scaled production systems and will provide direct mentorship as you grow. As the engineering team expands, there is also a clear leadership runway for someone who wants to take increasing ownership and eventually help lead the team. This is a profitable, stable company with real customers and real infrastructure.
