Ops Coordinator / Administrative Assistant

About Tacit We are an early-stage, deep tech startup based in San Francisco, developing innovative hardware that rethinks human-computer interaction. We are backed by General Catalyst, Khosla Ventures, and Greylock Partners, with a founding team from Stanford, BrainGate, Oculus, and Tesla. While we can’t reveal too much just yet, our team is tackling cutting-edge engineering challenges to bring revolutionary products to life.

About The Role

We're looking for an Operations Coordinator/Administrative Assistant to keep our office running and help us scale our team. You'll own office logistics, coordinate our hiring pipeline, and run onboarding for new hires — freeing up leadership to focus on strategy instead of logistics. The ideal candidate is resourceful, detail-oriented, and comfortable wearing multiple hats in a fast-moving startup.

This role is on-site 5 days/week at our office in South Park, San Francisco.

What You'll Do

Office Management

• Oversee everyday office operations, keeping the space clean, organized, and fully stocked; manage supplies, vendors, and facilities.
• Serve as the go-to point of contact for employees on office-related questions.
• Organize and execute team off-sites and onsite gatherings — venues, travel, catering, activities, and budgets. Recruiting & Onboarding Coordination
• Schedule and coordinate interviews across our hiring pipeline, keeping candidates and interviewers on track.
• Generate offer letters and manage new-hire paperwork using our existing tools (Ashby, Rippling).
• Own onboarding logistics end to end — equipment, system access, first-week schedule — so new hires have a smooth start. Administrative Support
• Provide back-up support to our Sr. EA for leadership support.
• Assist with travel coordination, meeting prep, and follow-ups.
• Flag process inefficiencies and help streamline workflows as we scale.
• Coordinate events, both internal and external.

Requirements

• 3–5+ years of experience in office management, people operations/coordination, or administrative roles, ideally at a fast-growing startup.
• Organized, proactive, and on top of the details.
• Strong organizational skills with the ability to multitask and prioritize effectively.
• Excellent written and verbal communication skills.
• Tech-savvy with proficiency in tools like Google Workspace, Slack, Zoom, and an ATS/HRIS (we use Ashby and Rippling).
• Friendly, approachable, and proactive in anticipating needs.
• Experience with event planning and execution, from small gatherings to larger company functions.
• Bonus: prior exposure to recruiting coordination or onboarding.

Benefits

• Comprehensive medical, dental, and vision insurance
• Company size: 30–50 people
• Unlimited PTO - 4% 401k matching
