Finance Manager – Part-time, 25 hours/week

Role Overview

• Build out finance function for Germany and the US: establish Chart of Accounts, reporting stack and closing processes for both entities.
• US setup via Mercury, QuickBooks Online, Ramp, Carta and Fathom/Mosaic.
• German setup via DATEV, in coordination with our tax advisor.
• Investor reporting: monthly investor update and a quarterly board package (P&L, Cash Flow, KPI scorecard, variance analysis) — at the level institutional investors expect.
• Grant and funding projects: manage ongoing and new grants with German authorities (BMWK, BAFA, EU programs) as well as US agencies (e.g., Department of Commerce, NIH mechanisms).
• AI and automation strategy: implement variance analysis, reporting drafts and anomaly detection using Claude/GPT workflows.
• Operational accounting: DATEV bookkeeping, EBICS banking, mailroom handling, receipt management, payment runs, and invoicing through the CRM.
• Transfer pricing & compliance: prepare arm’s-length documentation for the GmbH–US license agreement (IRS Section 482 / OECD) and readiness for due-diligence depth.
• Cash & forecasting: rolling 6-month planning, runway monitoring and three scenario planning (Base / Up / Down).

Requirements

• Background: Audit, tax or transaction experience at a Big Four firm (EY, PwC, KPMG, Deloitte) at Senior/Manager level — or equivalent.
• 6+ years of relevant experience.
• Dual standard: confident with HGB (German GAAP) and basic knowledge of US GAAP — or willing to build US-GAAP knowledge quickly.
• Understanding of group intercompany relationships (GmbH ↔ US Corp).
• Tools: strong command of DATEV. Experience with QuickBooks Online, Mercury, Ramp or comparable US stacks is a plus but not required.
• Languages: fluent in German and English.
• AI mindset: you actively use AI tools, not avoid them.
• Discretion: confidential data — cap table, salaries, investor communications — are handled with care.

Benefits

• Substance, not status: a senior, hands-on role with a strong build/scale focus — German bookkeeping meets a US scaling setup.
• This level of responsibility is rarely available for this number of hours.
• Genuine part-time: 25 hours means 25 hours.
• We design the role so it genuinely works alongside family commitments.
• Hybrid Berlin: 1–2 days in the office (Berlin), rest remote.
• Flexible core hours.
