We're looking for the person who will run the day-to-day administrative and financial operations of BTS Argentina: client invoicing, vendor payments, cash flow, and general office operations.

• Coordinate employee Magic Moments and key people moments (hires, exits and long-term leaves).
• Support ad hoc PX activities and help foster office culture and team engagement.

Who they are

• A team player — the role sits across finance, HR, and office ops, so it means constantly coordinating with different people.
• Proactive: escalates a deviation as soon as it's spotted.
• Sound judgment under pressure: knows to pause a beat before a fast decision with financial impact.

What they bring

• 2+ years of experience in financial, accounting, or office administration.
• Knows (or quickly learns) Argentine labor, tax, and invoicing regulations (AFIP/ARCA, social security contributions).
