As our new Financial Accountant, you won’t just be crunching numbers - you will be a vital pillar of a lean, high-impact three-person finance team, working alongside our Finance Manager and a Financial Controller (who aren’t afraid to roll up their sleeves and dive into the operational work with you).
Because we handle multiple administrations, numerous audits, and subsidy tracking, this role requires someone who can work fast, stay organized, and maintain high accuracy under tight timelines. This is an exceptional opportunity to handle a diverse ledger portfolio, take on real ownership, and rapidly develop your expertise in a supportive, collaborative environment.
Efficient Bookkeeping: Take full responsibility for the day-to-day financial tasks across multiple companies, working efficiently to manage accounts payable/receivable, bank reconciliations, and hour-recording tracking.
Intercompany & Tax: Handle intercompany reconciliations and prepare VAT declarations for the different entities.
Proactive Month-End Close: Drive the monthly close process forward at a steady pace for your assigned companies, ensuring all financial data is accurate, up-to-date, and ready for review by the Controller and Manager.
Audit Facilitation: Play a proactive, hands-on role in our numerous internal, external, and fiscal financial audits, serving as a reliable and responsive point of contact for auditors.
Documentation & Evidence: Swiftly gather, organize, and verify financial evidence and schedules required to ensure smooth, efficient audit cycles across our companies.
Year-End Support: Collaborate closely with the team to prepare the annual reports.
Grant Tracking & Compliance: Support the financial administration and project managers to track our subsidy grant portfolio, ensuring expenditures are accurately allocated to specific projects.
Subsidy Audits: Maintain pristine documentation and audit trails specifically for subsidy-related reviews to ensure compliance with grant requirements.
Years of Value: You have 2–4 years of experience in an all-round financial accounting or administrative role.
Multi-Company Exposure: Experience working with multiple entities or a multi-company structure is a plus.
Audit & Systems: You have practical exposure to audit preparations, solid Excel skills (intermediate level), and are comfortable navigating financial software.
English: Fluent (written and spoken) to easily collaborate with our diverse team.
Dutch: At least a working/basic understanding is required to independently process Dutch documentation, tax documents, and local invoices.
Fast-Paced & Productive: You are a quick worker who can manage your time effectively, switch contexts between different companies easily, and meet deadlines without sacrificing quality.
Meticulous & Organized: You have a keen eye for detail and a structured way of working - essential for handling multiple administrations and rigorous audits.
Friendly but Firm: You are approachable and collaborative, but you can confidently stand your ground when enforcing financial deadlines or compliance policies across departments.
Agile & Proactive: You thrive in a dynamic environment and are eager to learn and grow alongside a small, dedicated team.
We will be extra excited to meet you if you bring:
Hands-on experience with Exact Online
Prior experience with subsidy grants or multi-entity accounting.
