Prime Intellect is building the open superintelligence stack: the infrastructure frontier AI labs build internally, made available to every ambitious AI team.
Our platform, Lab, unifies compute, environments, evaluations, secure sandboxes, high-performance training, and deployment into one full-stack system for post-training at frontier scale - from SFT and RL to tool use, agent workflows, and continuously improving production models. We are building open frontier AI: open-source models trained end to end for long-horizon tasks like autonomous research, and the full-stack platform our own research team uses to build them. The next generation of AI companies, enterprises, and research teams do not just need more GPUs. They need the ability to turn their own workflows, tools, data, and feedback loops into superintelligence they own.
Prime Intellect has raised $150M in total funding from Founders Fund, Radical Ventures, NVIDIA, and exceptional AI, infrastructure, and enterprise operators — including Andrej Karpathy, Dwarkesh Patel, and leaders and founders from Ramp, Perplexity, Harvey, Mercor, Zapier, Datadog, Cognition, OpenAI, Thinking Machines, Together AI, SemiAnalysis, LangChain, Browserbase, Cloudflare, Sierra, Databricks, Airbnb, OpenRouter, Standard Intelligence, Fleet, Core Auto, and more. We are looking for people who want to build at the intersection of frontier research, real infrastructure, and go-to-market for a category that does not fully exist yet.
We are a team of about 60, split between our San Francisco office and remote staff, and we are hiring quickly. Every researcher, engineer, and operator who joins us has a first day, a first week, and a first impression of how seriously we take the people who build here. Right now, that experience depends on a lot of people doing a lot of small things right. This role makes it a system.
You will own the employee lifecycle from the moment a candidate is scheduled for an interview through a new hire's first weeks. You will design every new hire's first day, run onboarding end to end, coordinate recruiting logistics across multiple open searches, and help bring the team together in person. You will also be the person who looks at how this function works and makes it faster, more reliable, and more personal — including where AI tools and automation can take the repetitive parts off your plate so you can spend your time on the parts that only a person can do.
This is an in-person role based in our San Francisco office, reporting to our Executive Business Partner and working closely with the Head of Talent, hiring managers, IT, and finance.
Onboarding & Employee Experience
Design the first-day schedule and experience for every new hire so they feel welcomed and productive from day one, with a white-glove approach for executive hires
Set up desks and equipment before day one: laptop, monitor, welcome kit in place; coordinate provisioning, accounts, and tool access with IT
Coordinate finance onboarding — payroll, benefits enrollment, expense tools, company card — and office access: door access, building entry, and meal program
Complete required onboarding steps accurately and on time: background checks, I-9 verification, employee records, and HRIS setup
Identify immigration and visa needs early, route them to the right people, and track them to resolution
Maintain and continuously improve the onboarding system so every hire gets a consistent, well-run first week
Support offboarding: recover equipment and remove access
Recruiting Coordination
Own interview scheduling across multiple open roles so every candidate and interviewer shows up informed, prepared, and on time
Book travel and host candidates for onsite interviews and work trials, creating a warm, human candidate experience
Keep candidates and hiring teams informed throughout the process with timely, clear communication
Maintain Ashby as the single source of truth: stage updates, candidate notes, and pipeline hygiene
Own scheduling timelines and SLAs, surface risks early, and keep recruiters and hiring managers in the loop
Systems, Culture & Team Operations
Find smarter, faster ways to run this function, including automating repetitive work with AI tools
Track open hiring and onboarding tasks and follow through on every commitment
Contribute to an in-person culture that builds connection across in-office and remote teams
Help plan and run team onsites and offsites, including attendee logistics and travel
Take on recruiting operations and sourcing projects as the function grows
New hires feel expected and cared for. Before day one, they know where to go, what to expect, and who to ask for help.
Laptops arrive on time, accounts work, schedules are clear, and first-week travel is arranged. You check directly with each new hire rather than assuming everything is set.
Compliance steps — background checks, I-9s, records — are complete and accurate without anyone having to chase them.
Recruiting, IT, managers, and office teams know what they own. You spot delays and resolve them before they affect a start date.
Trackers, checklists, and communications stay current as hiring volume grows.
2+ years in recruiting coordination, people operations, HR, or a similar high-volume coordination role
Proactive coordination: you can juggle many starts, owners, and deadlines without losing the details, and you follow up before anyone has to ask
Real care for the employee and candidate experience — a warm welcome is built from both thoughtful communication and reliable execution
Comfort managing background checks, I-9 verification, employee records, and HRIS setup, and handling sensitive information with discretion, including for senior and executive candidates
Cross-functional follow-through: you make ownership clear and stay with an issue until it's resolved
Process improvement instinct: you spot recurring gaps in a checklist, handoff, or message and fix them
Highly skilled in tools like Google Calendar, Slack, and Notion, with demonstrated ability to handle high-volume work efficiently
AI-native in how you work: you use LLMs and automation to take repetitive work off your plate
Low ego, high ownership — as willing to improve a workflow as to track down a delayed laptop
Able to work in person in our San Francisco office
Bonus:
Experience with Ashby or another modern applicant tracking system
Experience running onboarding at a fast-growing startup
Experience coordinating immigration or visa processes with outside counsel
You will shape how every person who joins Prime Intellect experiences their first weeks, at a company where the people being onboarded are among the best researchers and engineers in the world. You will build the people operations foundation from an early stage, work directly with leadership and the Head of Talent, and have real room to grow into recruiting operations, people operations, or wherever your strengths take you as the company scales.
