Help us make a big green dent in the universe. We're on a mission to drive the global renewable energy revolution, and we need many more people to help us make our vision a reality.
 
Octopus Energy Generation (OEGEN) is a leader in sourcing, investing in, and managing a wide range of utility-scale renewable energy assets. As we continue to expand our investment base, we are dedicated to building a diverse team that reflects the communities we serve. Currently, we manage a global portfolio of over £7 billion in renewable energy assets.
 
We are committed to delivering best-in-class responsible investment activity, offering like-minded investors the means and products to invest their capital sustainably. It is our ambition to change the entire energy lifecycle and make every green electron matter, delivering the best outcomes for customers, investors, the environment and society, accelerating the transition to net zero.
 
About the role:

We are seeking a Portfolio Manager to join the OEGEN Fund Management Team, reporting to the Head of Funds and Sustainability. For your assigned portfolios, you will have full accountability for the quality, rigour and delivery of all fund management processes, including Investor (Equity) and Lender (Debt) Management. You will be an experienced people manager with at least one direct report and will ensure that governance, reporting and financial oversight are delivered to a consistently high standard.

The six funds under your responsibility are established partnership mandates investing across solar, onshore and offshore wind. These are closed to new investment and are now focused on disciplined value optimisation to deliver returns through asset performance enhancement, capital structure management and, where appropriate, exits.

This role requires a combination of process discipline and commercial judgement. You will take pride in producing clear, accurate and insightful investor reporting and will enjoy owning the cadence of quarterly valuations, board materials, lender reporting and performance analysis. At the same time, you will act as a steward of investor capital, challenging assumptions, identifying optimisation opportunities and bringing structured thinking to hold versus sell decisions. You will continuously improve fund management processes to ensure scalability as AUM grows, while maintaining strong investor confidence and governance standards.

Our process usually takes up to 4 weeks, but we’ll always do our best to flex around what works for you. Along the way, you’ll chat with our recruitment team and your Recruiter will help you throughout different stages. Got any burning questions before then? Drop us a message at [email protected] and we’d love to help!

Across Octopus, we're looking for genuinely decent people who are honest and empathetic.

What you'll do

  • Fund, Equity and Debt Management:  You will have full financial oversight and accountability of your assigned funds and all underlying assets through equity and debt financial models and will be a highly capable financial modeller. You will challenge, oversee and explain investor returns, valuations, track record and other fund KPIs, working collaboratively with other teams, ensuring accurate data and informative forecasts.  You will manage relationships with lenders. 
  • Valuations:  You will lead the process to perform bottom up asset level valuations on a quarterly basis across your renewables portfolios, overseeing the deliverables produced by your direct report(s), undertaking detailed assumption reviews and sense checking outputs from financial models to ensure valuations reflect current market value. You will retain full technical ownership of the valuation models, with the capability to update and interrogate them directly where required, while maintaining a robust, well-controlled and repeatable quarterly process delivered through your team. You will work collaboratively with the Valuations Lead and Product Heads to balance portfolio needs and build consensus on assumptions, and you will present and defend final valuations to the Investment Committee and Valuations Committee
  • Investor relationship management: You will understand the requirements and needs of investors within a fund and apply commerciality to our fund management processes, working alongside the appropriate Product Head. You will establish relationships with the investors and be a first point of call of inbound investor queries and act as a trusted representative of the fund to investors. 
  • Reporting: You will oversee the creation of investor deliverables that we are proud of with insightful and thoughtful KPIs and narrative, integrating ESG and impact and ensure reporting obligations of the funds are met. This includes working with the Finance team collaboratively on annual statutory reports and audits. You will lead on any operational due diligence requirements for the fund.
  • Risk Management: You will ensure that your fund is governed correctly, ensuring that the appropriate information is provided to enable decision making / focus on key issues.  You will understand the key risks associated with the portfolio across WEP variability, FX, macroeconomic factors, asset performance, HSE and ESG putting in place suitable policies and working collaboratively with teams ensure that appropriate policies and mitigation strategies are in place and that compliance responsibilities are actively monitored and met.
  • Value optimisation: You will drive value creation strategies across closed funds with a focus on maximising distributable returns and managing exit optionality. Working closely with Asset Management, Product Heads and Investment teams, you will proactively identify and evaluate opportunities to enhance asset and portfolio value including assessing hybridisation opportunities such as co-located storage and revenue stacking, evaluating repowering and life extension economics, challenging operating assumptions and merchant forecasts, reviewing refinancing or capital restructuring options, and considering partial or full asset disposals where this aligns to investor objectives and optimises IRR and cash yield outcomes. 
  • What you'll need

  • Knowledge, understanding and experience of managing infrastructure valuation processes. 
  • Previous experience of working in the renewables sector with an in-depth knowledge and skillset in renewables cash-flow modelling, debt modelling and distribution forecasting.
  • A good understanding of fund management processes for closed partnerships
  • Experience of fund financial processes and managing 3rd party outsourcers
  • Experience of leading the production of quarterly and annual reports 
  • Excellent financial acumen, CFA qualification considered advantageous.
  • And to really stand out from the crowd, you will display the following qualities and characteristics:

  • Enjoys the rhythm of fund management: building a reliable cadence, keeping stakeholders aligned and delivering accurate, high-quality investor reporting on time.
  • Process-minded and continuously improving: able to simplify, standardise and strengthen models and reporting workflows without losing rigour.
  • Commercial and inquisitive: able to spot value optimisation opportunities (hybridisation, repowering, refinancing, exit optionality) and structure analysis to support decision making.
  • Strong written and verbal communication skills, able to distil analysis into clear messages and handle investor and internal stakeholder queries confidently.
  • Detail-oriented and accountable, with a strong sense of ownership for the quality of outputs and underlying data.
  • Highly organised, able to manage multiple workstreams and deadlines in a fast-moving environment.
