Tax Assistant Manager

The Role

We are looking for a Tax Assistant Manager (or emerging Tax Manager) to join the OEGen Tax Team, reporting directly to the Funds & Deals Tax Lead.

This is an excellent opportunity for someone with around 4–5 years’ experience who is looking to step into a broader international role and continue developing their technical, commercial, and project management skills within a growing infrastructure investment platform.

The role will support a portfolio of OEGen funds and associated holding structures across multiple jurisdictions. You will work closely with investment teams, finance teams, portfolio companies, and external advisors on a wide range of tax matters, including compliance oversight, reporting, transactions, and structuring support.

The position offers broad exposure to international investment structures and cross-border transactions, while working as part of a collaborative and hands-on in-house tax team.

What you'll do

• Support the management of tax matters across OEGen funds and associated holding structures.
• Coordinate international tax compliance processes with local advisors across multiple jurisdictions.
• Assist with tax reporting, tax provisioning, and financial statement disclosures.
• Support tax workstreams on acquisitions, restructurings, refinancings, and other transactions.
• Review transaction and financing documentation from a tax perspective, with support from senior team members where needed.
• Monitor tax risks and support ongoing governance and compliance processes.
• Work closely with investment, finance, legal, and external advisory teams across the business.
• Contribute to the continuous improvement of internal tax processes and documentation.

What you'll need

• Around 4–5 years’ experience in corporate tax.
• CTA, ACA, or equivalent qualification (or close to qualification).
• Experience gained in a Big 4 firm, international advisory firm, law firm, or in-house tax team.
• Good grounding in tax compliance, reporting, and tax accounting.
• Exposure to cross-border structures or international tax matters is helpful, but deep expertise is not expected.
• An interest in infrastructure, energy, or investment management is a plus.
• Foreign language skills (particularly German, French, Spanish, or Italian) would be beneficial but are not required.
• Most importantly, we are looking for someone with strong reasoning skills, good commercial awareness, and a willingness to learn. This role would suit someone looking to grow into a broader international tax management role over time, working closely with experienced senior stakeholders in a supportive and collaborative environment.
