Operations Lead

At River AI, we are building an entirely new kind of AI company. As we move quickly across research, engineering, product, hardware, legal, security, HR, and go-to-market, we need people who can help the company move with clarity, speed, and fluidity. We are looking for a high-agency, highly versatile problem solver to work closely with all functions on River's most important operational challenges. You will identify what matters, bring structure to ambiguity, drive alignment, and keep critical work flowing from idea to execution. This is not a traditional operations role. You will operate across functions and levels, removing friction and creating connectivity so that information, decisions, and workflow where they need to go. The work will evolve with the company. You should be equally comfortable shaping a strategy, untangling a complex problem, building a new operating rhythm, or rolling up your sleeves to get something across the finish line. At River AI, our mission is to create personal AI owned and shaped by each individual. To achieve this, we are building the full stack required for people and organizations to create AI models of their own - from training infrastructure and open-weight model post-training to personal hardware and next-generation interfaces. We are scientists, engineers, and builders from the industry's leading technology companies and AI labs. Our team has experience scaling consumer products to hundreds of millions of users and building the infrastructure behind frontier AI systems. Significant experience in operations, strategy, program management, chief of staff, consulting, or a similarly high-ownership role. Experience operating in a fast-paced startup or high-growth technology environment. Exceptional problem-solving and judgment, with the ability to quickly assess a situation and determine a practical path forward. Comfortable with significant ambiguity and able to create structure where none exists. Strong cross-functiona
