Senior Executive Assistant to the CSO

Description
The Senior Executive Assistant provides comprehensive executive and administrative support to the Chief Sales Officer (CSO), ensuring effective coordination, communication, and information flow across the sales organization. The role encompasses calendar and travel management, preparation of executive-level reports and presentations, coordination of cross-departmental activities, monitoring of key deliverables, and facilitating communication between the CSO’s office, regional teams, business partners, and senior management.

Responsibilities

• Own the CSO's calendar end to end prioritize requests, protect focus time, resolve conflicts across time zones (Europe, LatAm, Asia)
• Screen and triage all incoming email, calls and messages; respond on the CSO's behalf where appropriate and escalate only what needs the CSO
• Plan complex international travel, visas, accommodation and itineraries, including trade shows and client visits (e.g. ICE, SiGMA, SBC events)
• Prepare the CSO for every meeting: briefing notes, background on attendees, previous discussion points, and desired outcomes
• Act as the main interface between the CSO and all sales staff, from routine requests to sensitive matters
• Run the CSO's operating rhythm: weekly team-lead meetings, regional reviews, 1:1s, quarterly business reviews — agendas, minutes, decisions and action items
• Track every action item and deadline the CSO assigns; chase owners, flag slippage early and close the loop without being asked
• Coordinate with other departments (Project Implementation, Marketing, Finance, Legal, HR) to unblock sales deals and internal requests
• Consolidate inputs from regional team leads into reports, dashboards and presentations for senior management and the board
• Build high-quality decks, memos and summaries in English (and other languages as needed) that are ready to send without rework
• Maintain trackers for pipeline updates, priority-country plans, partner status and team KPIs
• Do first-pass research on markets, competitors, prospects and regulation when the CSO needs a quick view
• Lead or coordinate special projects on the CSO's behalf: market-entry preparation, sales kick-offs, offsites, partner events
• Represent the CSO's office in internal meetings and with external partners when the CSO is unavailable
• Handle confidential information (contracts, compensation, strategy, personnel matters) with complete discretion
• Continuously improving how the CSO's office works: templates, processes, tools and automation

Requirements

• 5–7+ years as Executive Assistant, Chief of Staff or Office Manager to a C-level executive, ideally CSO, CCO, CEO or Managing Director
• Experience in a fast-paced international company; B2B tech, SaaS, iGaming or fintech is a strong advantage
• Track record of supporting a leader who manages multiple teams across regions and time zones
• Bachelor's degree in business, languages, international relations or a related field; a master's is a plus
• Fluency in English (C1–C2, business-level written and spoken), Russian, and Armenian is required; proficiency in Spanish, Portuguese, or other European or Asian languages is considered an advantage
• Excellent writing: produces clear emails, memos and executive summaries that need no editing
• Advanced MS Office / Google Workspace, especially PowerPoint and Excel (pivot tables, trackers, basic dashboards)
• Comfortable with CRM and collaboration tools (e.g. Salesforce or HubSpot, Jira, Slack/Teams, Notion) and with AI assistants to speed up work
• Strong project management: runs several workstreams at once and keeps every deadline visible
• Understanding of sales processes, pipelines and commercial terminology
