About The Role
Lilac is looking for a sharp, resourceful EA to anchor the CEO's calendar and travel while serving as a force multiplier for the entire C-Suite. The role suits someone who thrives on complexity, moves fast without losing attention to detail, and brings genuine warmth and support to a high energy team and environment. This role will report directly to the CEO.
What You'll Do
Own and manage the CEO's calendar; a fast-moving mix of board matters, site visits, investor meetings, and regulatory engagements. Proactively resolve conflicts and protect time for top priorities
Manage calendars, scheduling, and meeting logistics for three additional C-suite executives, balancing competing priorities with tact and clear communication
Arrange complex domestic and international travel across project sites and corporate locations, including flights, lodging, ground transportation, and detailed itineraries
Support external partners, visiting officials, and international hires with visa support letters, invitation letters, and other high-level documentation requests, ensuring accuracy and timely turnaround
Serve as a first point of contact for urgent, time-sensitive matters, including outside standard business hours, exercising sound judgment on what requires immediate escalation
Plan and execute logistics for leadership meetings and offsites, quarterly business reviews, board meetings, and company-wide events, including on-site support at select conferences or team gatherings
Process expense reports, invoices, and purchase orders on behalf of the CEO and other executives as needed
Draft, proofread, and format correspondence, memos, and internal communications on behalf of the executive team
Manage highly confidential information (operational, financial, personnel, and regulatory) with absolute discretion
Anticipate needs before they're voiced; from prepping briefing materials ahead of meetings to flagging scheduling conflicts before they become problems
Partner with facilities, IT, and site operations teams to coordinate executive visits to project sites, including safety briefings and logistics unique to industrial/field locations
Provide backup support to other administrative staff during absences and pitch in on ad hoc projects as priorities shift
Assist in building polished, executive-ready PowerPoint decks for board meetings, investor updates, all-hands presentations, and leadership offsites
Qualifications
5+ years supporting C-Suite or senior executives, ideally in a multi-site, industrial, mining, energy, or natural resources environment

A track record of building trust quickly with executives, board members, and cross-functional partners alike
Polished, professional presence paired with genuine warmth and energy
Proven ability to manage complex, frequently changing calendars and heavy travel coordination across time zones
Comfortable being "on call" for urgent matters and adjusting personal schedule when business needs require it
Sound judgment handling sensitive and confidential information with integrity
Strong written and verbal communication at an executive level
Highly organized with the ability to juggle competing priorities, from routine logistics to strategic initiatives, without losing momentum
Flexible and steady under pressure; energized rather than rattled by a fast-paced, evolving environment
Willingness and ability to travel approximately 20% of the time, including to project sites in varied field/industrial settings
Proficiency in Microsoft Office (Outlook, Word, Excel, PowerPoint, Teams, SharePoint) and familiarity with collaboration tools (Zoom, expense/travel platforms)
