Problem-solving and escalation: Understand the reasons behind delays, help resolve routine coordination issues, and bring management clear updates on blockers, risks, and decisions required. Executive support: Coordinate calendars and meetings, prepare agendas and relevant materials, capture decisions, and follow through on action items. Anticipate upcoming administrative and operational needs. Documentation and legal coordination: Organize company documents and approved contract templates; coordinate legal reviews, feedback, approvals, signatures, and renewals. Support official application paperwork, including visa, residence permit, and work permit documentation. Support to HR: Assist HR team with candidate calls, interview scheduling, candidate follow-ups, and recruitment and onboarding documents, following established HR processes. Presentations, reporting, and AI: Prepare presentations, management updates, summaries, and business correspondence. Actively use company-approved AI tools to improve productivity, checking outputs for accuracy and protecting confidential information. Daily administration and improvement: Handle routine correspondence, administrative requests, meeting arrangements, and guest reception when required. Identify practical ways to improve recurring workflows and information sharing. What We Are Looking For At least 3 years of relevant experience in operations, HR, Administrative affairs, executive assistance, project coordination, or a comparable role. Demonstrated experience independently coordinating work involving multiple people or departments. Strong interpersonal and team-coordination skills: able to build trust, listen carefully, clarify expectations, handle pushback professionally, and follow up firmly but respectfully. Good written and spoken English , with clear, professional communication and the ability to prepare well-structured documents and presentations. Strong prioritization, attention to detail, and practical problem-solving skills; able to work independently within agreed priorities and recognize when clarification or approval is needed. A genuine interest in technology and regular, practical use of AI tools , alongside confidence with digital task-management, collaboration, documentation, and presentation platforms. The ability to learn internal processes quickly, apply feedback, and adapt to changing priorities without losing accuracy or follow-through . A reliable, discreet, hands-on approach, with equal willingness to coordinate a cross-team action and complete the administrative steps needed to move it forward. Why Join Sigma Group? Work in a dynamic , fast growing and international environment. Work closely with leadership: Contribute directly to daily execution and gain visibility into business priorities and decision-making. Gain broad business exposure: Collaborate across technology, commercial, and support functions within an international business.
