Your role:

We are looking for a Financial Controller to own THEKER's financial operations during this critical phase of growth.

Your mission is clear: build the financial infrastructure, establish controls, and give leadership full visibility over the company's financial health at all times. You will own day-to-day financial operations, from cash management and month-end close to cost control and compliance, ensuring the company runs with discipline and accuracy.

This is a hands-on, operational role. You will work closely with the founding team on financial decisions as they arise, but your primary focus is execution: keeping the books clean, the numbers accurate, and the processes running without gaps.

• Own the month-end and year-end close process, ensuring accuracy and timeliness.

• Manage cash flow, burn rate, and runway tracking with regular reporting to leadership.

• Control operating expenses, process vendor invoices and payments, and manage accounts payable.

• Maintain the general ledger, reconcile bank statements, and keep the chart of accounts clean and up to date.

• Prepare and monitor budgets by department, tracking actuals vs. plan and flagging variances proactively.

• Support audit processes and ensure compliance with local tax and accounting regulations.

• Build simple financial models to support operational decisions (headcount planning, project costing, capex tracking).

• Manage relationships with external accountants, auditors, and banking contacts.

• Design and implement financial controls and approval workflows as the team grows.
