Senior Vivarium Supervisor

San Francisco, CA – Full-Time – On-site –- $100,000 - $150,000 per year. $10k referral bonus for successful hires (half equity, half cash). It's Monday morning. You walk in, grab your coffee, and look at the vivarium you helped build from scratch. Your vivarium. You check the board. First up: feed the mice. These are your mice - you set them up, you're responsible for everything that happens in this room. A vendor calls. Shipment delayed on the IVC rack you urgently need. Two weeks ago, you would've accepted that. Not anymore. You've learned to find the bottleneck, solve it. Thirty minutes later, the shipment is back on track. Then the chemist hands you a peptide - just synthesized in the rapid in‑house pipeline and ready to be tested. Today it's IV injections. You didn't know how to do that before you got here. Now it's one of a dozen skills you picked up in weeks, not months. This peptide didn't exist 24 hours ago. Our in‑house ML model designed it last night. Is it going to outperform the last version? You dose the mice, set everything up in the in‑house ML tracking system, and two hours later – results. The Mission In the age of ever‑improving AI capabilities, we humans are lagging behind. We're hungry, distractable, tired. A third of our day is spent unconscious. Half of us get cancer, half of us get heart disease. We're incapable of sustained high performance. We fall ill. The modern world feeds us slop that leads even further down the drain. We believe that humans are capable of more. We believe in excellence. We believe in superpowers. We believe in the extraordinary. We're a small core team. In 6 months, we have designed 270+ therapeutic candidates, run 72+ placebo‑controlled mouse trials, and completed 79 custom syntheses. We're planning first‑in‑human safety in 2026 — which would be a world record for a non‑vaccine therapeutic built from scratch. Our founding scientific advisors include professors at Harvard and MIT. At the pre‑seed stage, we raised $12M in funding from the best deeptech investors. What does a future look like where we can systematically identify, validate, and induce beneficial capabilities? The Role We're targeting first‑in‑human dosing by mid‑2026. If we hit it, this is also a world record for moving a non‑vaccine therapeutic into the clinic from scratch. Most biotechs take weeks to go from synthesis to animal data. Here, it happens in one day . We do not know of another lab on earth running this loop at this speed. One day. Synthesis to animal data. One day. You keep the vivarium running, perform core mouse assays, and hand the results to our ML team — who use them overnight to design the next version. Start‑ups are unique. Roles aren't as ossified or constrained as in a large corporation—you'll often learn a new role every few months, enabling you to grow as a person and team member.
