- Keep records, files, and shared systems organized and up to date
- Pitch in wherever needed to keep a growing team running efficiently

- 2+ years of administrative, operations, or office coordination experience, ideally in a startup, lab, or small-business setting
- Highly organized and self-directed, with strong attention to detail and follow-through
- Comfortable juggling varied tasks and shifting priorities
- Proficient with common office and productivity tools (email, calendars, spreadsheets, document sharing)
- Reliable, discreet, and able to work independently in person in Seattle, WA
- Experience with basic bookkeeping or procurement a plus
