Tax Assistant Manager

OEGen is a specialist energy investment manager overseeing more than £8 billion

of assets under management. Our mission is to accelerate the transition to a net

zero energy system by investing in clean energy infrastructure and energy

transition businesses across multiple jurisdictions.

As our international portfolio continues to grow, we are looking to strengthen

our in-house tax capability with the addition of a commercially minded tax

professional who is keen to develop within a fast-paced investment environment.

The Role

We are looking for a Tax Assistant Manager / emerging Tax Manager to join the

OEGen Tax Team, reporting directly to the Funds & Deals Tax Lead. The successful

candidate will join the tax function at Sky Generation, the UK clean energy

infrastructure platform of the Sky Fund, which owns and manages a number of

international operating platforms. These businesses are active across Europe and

beyond, developing, investing in and managing renewable energy and broader

energy transition assets.

This is a strong 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 capabilities within a growing

infrastructure investment environment.

The role will support the Sky Fund’s portfolio and associated holding structures

across multiple jurisdictions. You will work closely with investment teams,

finance teams, portfolio companies and external advisers on a broad range of tax

matters, including tax compliance oversight, reporting, transactions,

structuring and ongoing portfolio support.

The position offers wide exposure to international investment structures,

cross-border transactions and the full lifecycle of infrastructure investments,

while working within a collaborative, hands-on and growing 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.
