Job description

Position Overview

You'll own the day-to-day operations that keep Mach9 running: people, workplace, IT, internal systems, and the infrastructure that lets a fast-growing team scale without losing rigor. Reporting to the Head of Business Operations and Finance, you'll be the operating partner who turns process gaps into systems, automates manual work, and builds the function as the company grows from 25 to 60+. This is a hands‑on role at a Series A‑stage company. You'll be the person who sees what's breaking, fixes it, and then builds the system so it doesn't break the same way twice. You'll work closely with outside counsel on immigration, employment, and compliance matters, and own internal operations end‑to‑end.

Responsibilities

• People Operations: own onboarding and off‑boarding end-to-end; coordinate immigration matters with outside immigration counsel; own workplace policy and governance in partnership with outside employment counsel
• Employee Experience and Workplace: Run the SF office end-to-end, including building management, facilities, vendor relationships, and office moves. Beyond the physical, help build company culture and employee experience through team events, offsites, and more.
• Operational Infrastructure: Maintain SOPs, internal documentation, and the company wiki. Identify where processes are manual, inconsistent, or undocumented, and fix them before they become problems at scale. Own how the company thinks about operational infrastructure: which tools we bet on, where we invest in the process before we need it, and how we structure ourselves to scale.
• IT and Internal Systems: stand up and own the company's MDM; manage device procurement, identity, and the internal tech stack; build automations to eliminate manual work.
• Compliance and Security: project manage security audit (SOC 2), support business insurance, and ongoing compliance with state and federal employment requirements.
• Recruiting Operations: coordinate onsite interviews, candidate experience, and offer logistics in partnership with hiring managers

What You Bring

• 5–7 years in internal ops or chief‑of‑staff roles at high‑growth startups, including time at Series A through Series C stages
• Demonstrated ownership of internal systems implementations
• Comfort with ambiguity and pace; you thrive in a build environment where the playbook isn’t written yet
• High slope on AI tools
• Sound judgment on what to own, what to delegate, and what to escalation
• Warmth and professionalism; you represent the company internally and externally
