Senior Accounting Manager

Our mission at Avelios is to build the leading software platform for the data-driven digitization of hospitals and patient care. To do so, we have built a modular software platform that digitizes and optimizes workflows in hospitals with cutting-edge technology in a user-friendly way. With our software, we enable hospitals, doctors & nurses to provide their patients with the best possible care.
We are growing fast and want to keep expanding our team and business to fundamentally digitize healthcare for the better. We appreciate different backgrounds and see diversity as one of our strengths.

As a (Senior) Accounting Manager (all genders), you take hands-on ownership of accounting, financial governance, and audit readiness. You ensure that our core financial processes run reliably, with strong controls and scalability — creating the data and process quality that management and investors rely on for decision-making.

You are fully responsible for the monthly and annual financial close in collaboration with our external accounting firm, ensuring accurate and audit-ready financial data. You also oversee our operational finance processes — from invoicing and accounts receivable management to approval workflows — and thereby build the foundation for efficient operations and high-quality reporting.

You report directly to our Head of Finance and serve as the primary point of contact for external partners, including tax advisors, auditors, and customer accounting departments.
