**Executive Assistant to Co-Founder**
Cancún / Riviera Maya - Hybrid
Onivius - International Real Estate Investment Platform
**About Onivius**
Onivius is a boutique real estate investment and development ecosystem focused on high-end residential and resort-style projects in the Riviera Maya.
We are currently in an early-stage growth phase and building the foundations of a long-term company. As a startup, our structure is evolving quickly and we are looking for someone who wants to **grow with us and become a trusted operational partner to the founder**.
This role is not a traditional assistant position.
We are looking for a **strategic right hand to the founder** — someone who can protect executive time, coordinate priorities, and help drive execution across the organization.
**The Role**
You will work directly with the Co-Founder and act as a **strategic filter and operational extension,**protecting executive time and ensuring high-level priorities move forward.
This means three things:
- Someone who **executes reliably**
- Someone who **thinks with the founder**
- Someone who can **partially replace the founder on operational coordination**
You will gradually receive **delegated organizational authority** to help structure communication flows, priorities, and internal accountability.
This role requires independent judgment and the ability to act on behalf of the founder when appropriate.
Trust, discretion, and alignment with our vision are essential.
**Key Responsibilities**
- Drafting high-quality communications in English and Spanish
- Preparing meeting briefs and summaries
- Coordinating follow-ups across departments and partners
- Tracking priorities and ensuring deadlines are respected
- Protecting the founder’s time and focus
- Supporting investor, partner, and strategic communications
- Helping structure internal organization and execution flow
**Profile Required**




- Fully bilingual **English / Spanish** (strong written communication required)
- Strong organizational and analytical thinking
- Ability to prioritize independently and make judgment calls
- High level of discretion and confidentiality
- Comfortable working directly with founders in a fast-moving startup
- Able to **execute tasks efficiently while also thinking strategically**
- Someone we can **trust with responsibility and delegated authority**
Experience supporting founders, executives, or fast-growing companies is a strong advantage.
**What Success Looks Like**
- The founder’s time becomes protected and focused on strategic priorities
- Communication flows become clearer and more efficient
- Teams and partners receive consistent follow-ups and accountability
**Compensation**
Part-time to start (15-20 hours per week), with growth opportunity into a long-term strategic role.
You will not simply “assist”. You will help build the operational backbone of a growing company.
We are looking for someone who believes in the vision, wants to grow alongside the founders, and is ready to become a trusted operational partner.
**Job Type**: Part-time
Pay: $15,000.00 - $18,000.00 per month
Expected hours: 15 - 20 per week
Application Question(s):
- Do you have experience supporting a founder, executive, or senior leadership directly?
- Are you fully bilingual in English and Spanish (written and spoken)?
- Are you comfortable managing and prioritizing an executive’s inbox and responding on their behalf when appropriate?
- Are you comfortable making prioritization decisions without needing constant supervision?
- Are you comfortable taking initiative and solving problems without waiting for instructions?
- Have you worked in a environment such as a startup or entrepreneurial company?
