AI Evaluation
Remote contractor role on a frontier AI data initiative: build Python backends that replicate SaaS tools (Slack, Linear, Jira, Notion, Gmail), author realistic long-horizon tasks from mined workflows, and write evaluation rubrics used to train and evaluate AI agents. $300 per approved task, 2-3 week engagement.
We're looking for engineers who have shipped production search systems (especially agentic ones now that we're in the era of LLMs and agents) and are thinking hard about the requirements and optimizations of those systems.
Remote contractor role evaluating and improving agentic coding models: reviewing model trajectories, verifying solutions, designing realistic coding tasks, and producing high-quality annotations. 5+ years of software engineering.
