Our client is a pre-seed startup working in the AI model-evaluation space, building the infrastructure that measures how the leading AI models perform on rigorous, domain-specific tasks. They are backed by a top Silicon Valley seed fund and partner with major players across the AI ecosystem. This is an early, high-autonomy environment where you would help shape the engineering culture and own significant parts of the platform from day one.
Founded 2024, about 25 people, Industry: AI and Software Development.
We are hiring a generalist software engineer to join the platform team and build the systems that run large-scale model evaluations end to end. You will work across the stack in a fast-moving environment, taking open-ended problems and shipping solutions independently.
