Job Description

Position: Snr Executive Assistant/Chief of Staff

Location: South America

Employment Type: Full-Time

Working Hours: M-F | MST Zone

Type of contract: Independent contractor

🌎 Work from any corner of South America and be a core extension of an executive leadership team.

About the Company:

A fast-growing, founder-led international business operating across multiple functions and markets. The executive you’ll support requires a highly autonomous partner who can think strategically, act decisively, and represent them with confidence in day-to-day operations.

Scope of the Role:

This is not a traditional Executive Assistant role. This position sits between Executive Assistant and Chief of Staff, designed for someone who can manage complexity, take ownership, and act on behalf of the executive when needed.

You will be trusted to represent the executive in meetings, make informed decisions within defined parameters, and keep the business moving forward without constant oversight. You are expected to operate with discretion, judgement, and a strong sense of accountability.

Responsibilities:

• Act as a strategic partner to the executive, managing priorities, workflows, and execution across the business
• Represent the executive in internal and external meetings, documenting outcomes and making decisions when authorised
• Act on behalf of the executive in communications, follow-ups, and coordination with stakeholders
• Own calendar management, inbox triage, travel coordination, and meeting preparation at an executive level
• Drive execution on projects, ensuring deadlines are met and blockers are resolved proactively
• Prepare briefs, summaries, presentations, and decision documents
• Coordinate across teams (Operations, Marketing, Finance, HR, etc.) to ensure alignment
• Anticipate needs, flag risks, and propose solutions before issues escalate
• Maintain strict confidentiality and exercise sound judgment at all times

Requirements:

• 5+ years of experience as an Executive Assistant, Senior EA, Operations Manager, or Chief of Staff–type role
• Proven experience representing an executive and making decisions on their behalf
• Exceptional written and verbal communication skills in English
• Strong business judgement and ability to operate with minimal supervision
• Experience working with founders, C-level executives, or high-growth companies
• High level of organisation, prioritisation, and follow-through
• Comfortable managing ambiguity and shifting priorities
• Based in South America with reliable availability aligned to US time zones

• Tech-savvy and comfortable with tools like Google Workspace, Slack, Notion, Asana, ClickUp, or similar

Ideal Personality Type (Critical for Success):

• Highly autonomous: You do not wait to be told what to do
• Decisive: Comfortable making informed decisions and standing by them
• Calm under pressure: Handles high-stakes situations without emotional reactivity
• Proactive thinker: Sees problems coming and acts early
• Executive presence: Communicates with confidence, clarity, and authority
• Discreet and trustworthy: Handles sensitive information with maturity
• Ownership-driven: Treats the business as if it were their own
• Low-ego, high-impact: Focused on outcomes, not titles
