ABOUT THE ROLE
We’re looking for an Executive Assistant to work directly with the founders and help keep the company running smoothly day to day. This is not a traditional “calendar-only” role.
This role is ideal for someone who is highly motivated, exceptionally organized, proactive, and driven to grow. You should be someone who sees what needs to be done and does it — without waiting to be told — and who is excited to take on increasing ownership over time.

Coordinate meetings across internal teams, customers, investors, and partners
Prepare agendas, notes, and follow-ups to ensure meetings turn into action
Act as a trusted right hand by anticipating needs and staying several steps ahead
Light Operations & Execution
Support day-to-day operational tasks and logistics
Own small projects end-to-end (travel, events, onboarding, internal coordination)
Track action items and ensure nothing falls through the cracks
Proactively identify inefficiencies and help improve processes
Ownership & Growth
Take initiative without needing constant direction
Look for ways to make the founders and team more effective
Learn how decisions are made in a fast-growing startup
Grow into broader operations, chief-of-staff–type, or program roles over time
WHAT YOU BRING
0–3 years of experience (EA, operations, project coordination, or similar)
Highly motivated with a strong internal drive to grow
Extremely organized and detail-oriented
Proactive and self-directed — you don’t wait to be told what to do
Strong written and verbal communication skills
Comfortable juggling multiple priorities in a fast-paced environment
High ownership mindset and strong sense of responsibility
Discretion and professionalism when handling sensitive information
Bonus (not required):
Startup or high-growth environment experience
Interest in operations, leadership, or strategy long-term
Familiarity with tools like Google Workspace, Notion, Slack, Zoom
WHAT YOU WILL LOVE AT MITHRL
Direct exposure to founders and leadership
Real ownership and trust from day one
Steep learning curve and mentorship
