SF Site Operations Manager

Plasmidsaurus is growing quickly, and our San Francisco headquarters needs to keep pace. As SF Site Operations Manager, you make sure the lab and office run smoothly every day so scientists can focus on sequencing, employees have a positive and efficient workplace, and candidates, customers, and visitors have an exceptional experience at our headquarters.

You're the connective tissue that keeps the site running: lab inventory, equipment maintenance, deliveries, and BSL2 safety execution, alongside workplace operations, candidate visits, local vendors, facilities issues, and employee events.

You'll work closely with Procurement to make sure supplies are never a bottleneck. That relationship should feel like a partnership that clears the path, not a gate scientists have to get through.

This is a hands-on operating role for someone who notices what needs fixing, takes ownership quickly, and makes the site feel organized, reliable, and easy to work in
