About us Quadrillion is a startup building Qualia, an agentic research platform (think Jupyter or VS Code, but with AI agents that do the actual research). Our users are ML researchers, quants, and data scientists who use Qualia to run an entire research project from a single prompt. We're a 12-person team in NYC, backed by $18.3M from Conviction, Audacious, Bloomberg Beta, ex/ante, and Wes McKinney (creator of pandas). We have one of the strongest NYC AI teams, with backgrounds from HRT, Google Research, Citadel, and Jane Street. The role Your role will be the same as any Quadrillion full-time engineer's: shipping real product changes, fixing customer bugs, and building new features. We're hiring interns for a couple of our groups: • Agent Engineering builds the core infrastructure that our agents run on: orchestrating agent loops, building the sandboxed environments where agents run experiments against real data, designing the APIs and tooling researchers touch, and scaling the infrastructure that keeps it fast and reliable. • Product builds an incredibly strong UI for agents to run in and for humans to interact with, both as a Mac/Windows app and on the cloud. What you'll do • Build effective systems for agent orchestration. You'll engineer the core system that drives Qualia, improving its ability to reason over long horizons, run parallel experiments, and manage its knowledge. • Scale environments for agent experiments and training. Help us build the sandboxed compute where agents run complex, high-performance experiments, and scale it to tens of thousands of concurrent deployments. • Expand what agents can do and where they run. Build and deploy the tools and integrations that connect Qualia to customers' data sources and external systems. Required qualifications • Strong full-stack or backend engineering experience, especially with Python • Comfort working in unfamiliar codebases • Ability to move quickly in a zero-to-one environment Who we're hiring We're hiring a strong intern with significant engineering chops in either Python or React. We prefer sophomores and juniors but are open to frosh. You must be a current undergraduate at a US or Canadian university. About this role We work in-person 5 days a week out of our office in Midtown Manhattan. We cover generous benefits for employees, including medical, dental, and vision insurance, lunch and dinner covered, and other varied stipends. We pride ourselves on a company culture that values a diversity of thoughts and opinions. About Quadrillion Quadrillion Labs builds Qualia, an agentic research intelligence platform that does real computational research — running experiments, analyzing data, and surfacing insight for the people who do this work at the highest level. We're a team out of Stanford NLP, HRT, Citadel, Jane Street, Google Research, and Harvard Med, building for an audience that looks a lot like us. We've raised ~$18M from Conviction, Audacious, Bloomberg Beta, ex/ante, and angels including Wes McKinney, the creator of pandas. We're ~10 people in NYC, scaling to ~15 in the coming months. We think this is the Industrial Revolution moment for research, and we're building the team to define what comes next. Equal Employment Opportunity Quadrillion Labs is an equal opportunity employer. We make hiring and employment decisions without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, genetic information, veteran status, or any other characteristic protected by federal, state, or local law.
