About O3 Partners

O3 Partners is a European GP stakes investor across venture capital, growth and private markets.

With offices in Rotterdam, Vienna, Budapest, Bucharest, Warsaw and Helsinki, we operate at the intersection of institutional quality, entrepreneurial speed and cross-border complexity.

The role

We are looking for a senior leader to head our Fund Operations function across the group. This is a critical role at the heart of our activities, responsible for ensuring that our funds operate with institutional-grade governance, best-in-class investor reporting, and scalable operating infrastructure, transparency, and scalability.

You will oversee the full operational lifecycle of our funds, lead and grow a dedicated team, and play a key role in modernizing and digitalizing our reporting and portfolio management processes with a particular focus on high-quality, timely and decision-useful information for LPs and other stakeholders.

  • Audit processes and coordination with external auditors

  • Managing and expanding a currently three-member fund operations team based in Budapest and Vienna

  • Acting as a senior counterpart to:

  • External fund administrators, auditors, legal and tax advisors

  • Internal investment, portfolio management and finance teams

  • Supporting the digitalisation and automation of portfolio management, reporting and data workflows

  • Contributing to the further institutionalisation and scaling of the O3 Partners platform

What we are looking for

10+ years of relevant experience in fund operations, fund administration, finance or audit, ideally within;

  • Venture capital, private equity or private credit

  • Multi-jurisdictional European fund structures (Luxembourg RAIFs, Dutch, Nordic or similar vehicles)

  • Strong understanding of:

  • Fund accounting and NAV processes

  • Regulatory and reporting requirements

  • Audit coordination and governance

  • Institutional investor reporting standards, LP communication practices and data transparency expectations

  • Hands-on experience working directly with institutional LPs (pension funds, insurers, FoFs, family offices) in an operational or reporting capacity

  • Up to date experience concerning online and other digital tools and solutions to be used for fund operations, accounting and reporting purposes

  • Proven people management experience and ability to build and lead growing teams

  • Comfortable operating in a cross-border, multi-office environment

  • Hands-on mindset combined with senior-level judgement

  • Strong English skills (additional European languages are a plus)

What we offer

  • A senior, high-impact role in a fast-growing European investment platform

  • Direct exposure to institutional investors and a meaningful role in shaping the firm’s external credibility and reporting standards

  • Exposure to a broad range of fund structures, strategies and geographies

  • Real influence over how fund operations are designed, scaled and digitalized

  • Collaborative, international team culture

  • Competitive compensation aligned with seniority and responsibility
