About the role
Onodrim is building Europe's largest defence and industrial platform. We acquire specialist manufacturers in critical defence and dual-use supply chains, then invest behind their growth with capital, technology and operating know-how.
As Senior Finance Manager, Controller - reporting to the Head of Finance - you will own the accounting backbone of the group. Every company we acquire has its own account set-up, policies and business model. One of your responsibilities is to turn that into one consolidated group under IFRS. Similarly for seamless compliance across the group, forecasting as well as in- and external reporting.
This is a role for a builder; it is not about maintenance. You will help set the policies, design the consolidation and reporting process and then run it as the Onodrim group grows across Europe.
What you will do
- Management reporting. Run monthly reporting across subsidiaries’ KPI’s. Analyse results against budget and prior periods, explain variances and identify issues pro-actively.
- IFRS consolidation. Own a growing group consolidation end-to-end: intercompany accounting, FX, PPA and improve or design underlying processes.
- Integrate acquisitions. Drive financial post-merger integration: opening balance sheet, close, controls and reporting. Support financial due diligence on closing deals.
- Strengthen systems and controls. Help shape the group's finance systems and tooling, and put in place controls for a growing, highly acquisitive group.
- Set accounting policies. Write and maintain group accounting policies under IFRS, and bring subsidiaries reporting consistently under local GAAP.
- Support operating teams. Be a finance partner for subsidiary MDs and our operations teams as regard cost analysis, working capital and capex.
- Forecasting. You support rolling (cash) forecasting models and own scenario analysis.
- Month-end close. Design a fast, reliable state-of-the-art month/year-end close process.
- Compliance. Own (tax) compliance with external advisors, bank (covenant) reporting and support the treasury processes.
- Own the audit. Main point of contact for group and statutory auditors and prepare audit-ready IFRS group FS. Design a single group chart of accounts mapped to each subsidiary.
- Grow the team. Build and lead the group accounting function as Onodrim scales.
Requirements
What you bring
- 8–10 years' experience in accounting and financial / business control, including time in a Big Four or similar audit firm.
- A professional accounting qualification – RA, RC, ACA, ACCA, CPA or equivalent.
- Track record of integrating acquired businesses: harmonising policies, merging charts of accounts and bringing new entities into group reporting.
- Deep, hands-on IFRS knowledge, including consolidation of multi-entity, multi-currency ledgers.
- Experience scaling finance processes through international growth.
- Strong analytical skills: you go beyond producing the numbers to explaining what drives them.
- Clear, direct communication in English, written and spoken, with the ability to explain accounting to non-financials.
- A hands-on approach: comfortable building processes from scratch and doing the detailed work yourself.
- Right to work in the Netherlands or the EU.

- Experience in manufacturing, industrials or defence, including inventory and product costing.
- Experience in a private-equity-backed or M&A oriented group.
- Hands-on experience implementing or consolidation ERP systems.
- Clearance in at least one of our operating countries.
