About The Role We're hiring a Senior Applied Machine Learning Engineer to join the small team that makes AI work tractable, safe, and fast across the company.

What You'll Do Partnering closely with our AI Function lead, you will work across all three of our AI products: Moderate, Discover, and Respond. Your focus will be on the highest-risk applied ML work and strengthening the foundations (eval harnesses, observability, reference implementations) that make AI work repeatable for engineers who aren't ML specialists. Own high-difficulty applied ML features end-to-end, from prototype through production. Build eval pipelines, golden datasets, and observability tooling (much of this is greenfield). Create reference implementations that show other engineers how to ship AI the right way. Partner with Product and Engineering to translate between what's technically feasible and what teams are trying to build. What We're Looking For 5+ years building applied ML systems in production Hands-on experience with LLMs, including classification, summarization, RAG, and agentic workflows Strong ML evaluation instincts: constructing datasets, running offline and online evals, defining metrics Ability to own a feature end-to-end without a lot of hand-holding Strong Python skills and comfort working in a production codebase Experience building internal tooling or platforms that leveled up other engineers is a big plus What We Offer Competitive salary + equity 100% remote, with optional access to our Boulder, CO office Flex PTO, generous holidays, and a full week off between Christmas and New Year's Multiple healthcare options including FSA/HSA plans 401k (traditional and Roth) with company match, immediately vested Fully paid family and parental leave (12 weeks per year) Twice-yearly team offsites Compensation $140,000 - $175,000 per year DOE + bonus + equity Location: This is a 100% remote role.
