About AfterQuery
AfterQuery is an applied research lab curating data solutions for foundation model development. We serve every frontier AI lab with the mission of delivering the best data to power the best models. In doing so, we can make expertise that once took a lifetime to build available to anyone who needs it.
Our customers are the ones building the foundation models themselves and our work sits directly in the loop of how those systems improve. This is a rare opportunity to join a company at a defining moment in AI. Forbes reported that we could be YC's fastest unicorn, reportedly raising at a $3.2 billion valuation. We're based in San Francisco and backed by leading investors including Altos Ventures, BoxGroup, and Y Combinator and angels from Google DeepMind, OpenAI, Anthropic, Meta Superintelligence Labs, and Microsoft AI.
Why Apply
Massive Opportunity: Forbes reported that we could be YC's fastest unicorn, reportedly raising at a $3.2 billion valuation, and we're not slowing down.
Founding Impact: You will own and architect core infrastructure systems that power our platform from the ground up.
Equity & Growth: Competitive salary and meaningful equity. As we scale, you’ll have the opportunity to shape the engineering organization and lead major technical initiatives.

Overview
Your job is to make ambitious research programs move. You will own the execution of programs spanning post-training, enterprise post-training, fellowships, evaluation releases, and partner research. You will turn open-ended research goals into clear plans, keep researchers, engineers, SPLs and external partners aligned, and surface the decisions and blockers that matter. This is not a traditional project-management role. You must understand the technical work well enough to reason about experiments, datasets, evaluations, training pipelines, and research tradeoffs. Your impact will come from creating just enough structure for the team to run more programs, make better decisions, and ship high-quality work faster.
Responsibilities
Own planning and execution across post-training, enterprise post-training, fellowship, and public evaluation programs.
Translate ambiguous research objectives into milestones, owners, dependencies, success criteria, and decision points.
Maintain a trustworthy view of program health, including experiment progress, risks, blockers, partner dependencies, and upcoming releases.
Required Qualifications
2-4 years project/program management experience
Experience leading complex technical programs across research, machine learning, engineering, or data organizations
Working knowledge of the LLM development lifecycle, including data creation, SFT, RL-based post-training, and evaluation
Strong communication and an ability to turn messy technical information into clear decisions and next steps
Company Benefits (For Eligible Employees):
Health Insurance: Medical, Vision, Dental
401(k) with Employer Match
