(Senior) Group Accountant – M&A Integration / Beteiligungsbuchhalter (m/f/d)

As a (Senior) Group Accountant – M&A Integration, you will take ownership of the operational execution of post-merger integrations (PMI) across a growing portfolio of entities.

While the M&A team focuses on acquisitions and a dedicated function defines the PMI blueprint, your role is to bring this blueprint to life — ensuring that newly acquired entities are smoothly integrated into the Group’s accounting, financial processes, and system landscape.

You will act as the central operational point of contact for local finance teams, coordinating day-to-day activities, aligning processes, and ensuring that accounting, intercompany structures, and financial flows run reliably and efficiently.

Your success will be measured by how effectively you translate structure into execution — enabling a fast, clean, and scalable integration that supports an efficient group close.

What is your Day to Day Mission:

PMI Execution & Entity Integration

• Execute the post-merger integration (PMI) roadmap based on the defined blueprint

• Coordinate the day-to-day integration activities of newly acquired entities

• Ensure smooth onboarding into Group accounting, reporting, and consolidation processes

Operational Accounting Coordination

• Align and stabilise local accounting operations in line with Group standards

• Ensure timely, accurate, and complete financial data delivery from all entities

Systems & Process Integration

• Maintain high data quality and transparency across all integrated entities

Stakeholder Coordination & Continuous Improvement

• Build strong working relationships with local finance teams and key stakeholders

• Coordinate closely with the M&A team and Business Development for smooth handovers

• Identify operational gaps and drive pragmatic improvements in processes and execution

What you bring to the team:

• Have 4–8+ years of experience in Accounting / Group Accounting / Audit, ideally in a multi-entity environment

• Are highly operational, hands-on, and execution-driven

• Are comfortable managing multiple entities and stakeholders in parallel

• Have solid knowledge of IFRS (or strong local GAAP with IFRS exposure)

• Understand how to translate defined processes into practical, working solutions

• Are structured, pragmatic, and able to bring order into complex environments

• Are fluent in English (German is a strong plus)

Nice to Have

• Experience in post-merger integration (PMI) execution

• Background in a manufacturing or industrial environment
