By leveraging autonomous, agentic research pipelines and proprietary algorithmic models, N0S and its affiliate, N0S Capital, provide high-conviction alpha strategies to both external investment firms and internal portfolios.

Role Objective

The Executive Assistant is a trusted operational and communication partner to our senior executive partner. This role focuses on executive readiness, communication quality, logistical excellence, and situational judgment, rather than routine administrative tasks.

The Executive Assistant enables executives to operate at the highest level by managing complex logistics, preparing for high-stakes interactions, maintaining discretion, and demonstrating strong judgment—especially in dynamic, high-pressure environments.

Success in this role is measured by:

• Accuracy and reliability in executive scheduling, travel, and logistics
• Quality, clarity, and professionalism of executive-facing and external communication
• Ability to anticipate executive needs and risks before they surface
• Judgment and discretion in confidential, ethical, or sensitive situations
• Composure and effectiveness under pressure or last-minute changes
• Attention to detail in operations, preparation, and executive readiness
• Cultural fluency and effectiveness in international and cross-cultural settings

Key Responsibilities

• Provide high-level executive support including calendar management, scheduling, and meeting coordination
• Plan and manage complex domestic and international travel, often with short notice
• Prepare detailed itineraries, briefing materials, and logistical plans to ensure executive readiness
• Serve as a professional communication bridge between executives, internal teams, and external partners in English and Mandarin Chinese
• Draft, review, and manage sensitive correspondence and materials with precision and discretion
• Maintain strict confidentiality and apply sound ethical judgment at all times
• Support executives during high-stress periods by maintaining operational stability and professionalism
• Assist with special projects and executive-level initiatives as required

Required Qualifications & Skills

• Fluency in English and Mandarin Chinese (spoken and written)
• Proven experience supporting senior executives or leadership teams
• Exceptional organizational skills with a strong eye for detail and precision
• Strong written and verbal communication skills suitable for executive representation
• Ability to manage ambiguity, last-minute changes, and high-pressure situations
• High level of integrity, discretion, and ethical judgment
• Proficiency with Microsoft Office Suite and scheduling systems
• Willingness and ability to travel frequently and support extended or irregular hours when required

Preferred Experience

• Experience supporting executives in technology, consulting, or international business environments
• Experience working with global or cross-cultural teams
• Exposure to executive-level decision-making or high-stakes engagements

Character & Personality Fit (Critical)

We are specifically looking for someone who demonstrates:

• Professional maturity and emotional intelligence
• Calm, respectful communication—even when receiving blunt or direct feedback
• Strong ethical standards and sound judgment in sensitive situations
• Proactive thinking and anticipation of executive needs
• Curiosity and a strong desire to learn from executive exposure
• Cultural awareness and adaptability across communication styles
• Reliability, resilience, and composure under pressure
• Frequent travel with executives is required
• Flexibility to support extended hours during travel, including evenings and executive events
• Ability to remain organized, prepared, and professional while on the road

Why This Role Is Attractive

• Direct exposure to senior executives and real-time decision-making
• Opportunity to develop an executive mindset and high-quality standards (“QA sensor”)
• Significant learning through hands-on executive operations and international exposure
• High-trust role with increasing responsibility and influence over time
• Dynamic, intellectually challenging, and culturally diverse work environment

Who Will Succeed in This Role

This role is ideal for someone who:

• Takes pride in precision, judgment, and professionalism
• Thrives in demanding environments with high expectations
• Sees executive support as a strategic function, not clerical work
• Is seeking long-term growth through close executive partnership
