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 £8 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 Associate to join the OEGEN Funds Team, reporting to the Senior Portfolio Manager.

The role will work across OEGEN’s listed funds, semi-liquid strategies and private funds, supporting investments in renewable infrastructure and liquid investments.

You will support the Senior Portfolio Manager across the full fund-management cycle, including portfolio analysis, valuations, cash-flow forecasting, debt, FX, hedging, governance and investor reporting. You will also have a particular role in analysing allocations and underlying fund information across semi-liquid and liquid strategies, reviewing valuations and asset performance across private market investments, and supporting the Finance team with monthly NAV processes.

The role would suit someone with a strong finance, accounting or investment background who is analytical, organised and comfortable working across recurring processes and more judgement-led portfolio analysis. It offers the opportunity to develop broad fund-management experience across a varied set of OEGEN portfolios.

What You'll Do

Portfolio management: Support the Senior Portfolio Manager with the day-to-day management of assigned portfolios, including monitoring investments, asset performance, fund KPIs, distributions, commitments, liquidity and investor returns. You will work with Asset Management, Investment, Finance and other teams to understand issues and ensure that actions are followed through.

Valuations and financial modelling: Support monthly, quarterly and annual valuation processes, including updating and reviewing DCF, investment and fund models, analysing assumptions, preparing valuation bridges and sensitivities, and challenging outputs from internal teams, external valuers and underlying managers. You will prepare clear analysis for internal and external stakeholders.

Cash flow, debt and hedging: Support cash-flow forecasting and analysis across the portfolios, including distributions, capital calls, liquidity, recycling and commitments. You will also help monitor debt structures, refinancing activity, managing covenants, hedging and other financial arrangements relevant to the funds, working closely with Finance and Investment teams.

Allocation and underlying fund analysis: Support analysis of portfolio construction, asset allocation and investment exposures, including gathering and assessing information from underlying funds and managers. This will include helping to draw together performance and portfolio information from semi-liquid and liquid investments and turning it into useful fund-level analysis and reporting.

Investor reporting: Lead or coordinate inputs into high-quality investor reports, factsheets, customer board materials, investor meetings and due diligence responses. You will help explain asset and portfolio performance, allocation, valuation movements, distributions, risks and outlook clearly and accurately for investors across the different fund types.

Private fund NAV and reporting: Work with the Finance team to support monthly NAV processes for underlying private funds, including checking underlying information, reconciling movements and maintaining clear supporting evidence. You will also help oversee and report on asset performance, review valuation outputs and identify questions or inconsistencies for escalation.

Risk and governance: Support the Senior Portfolio Manager in ensuring that funds are governed correctly and that information provided to Boards, customer boards, auditors and other governance forums is accurate. You will monitor risks including underperformance, valuation movements, liquidity, debt covenants, mandate constraints and material data gaps, escalating issues promptly.

Process improvement: Maintain accurate fund-level information for NAV, AUM, returns, distributions, commitments and track record, and look for practical improvements to reporting, controls, data collection and automation. You will help ensure that processes are documented, deadlines are managed and outputs are consistent and auditable

What You'll Need

At least three years of relevant experience in fund management, fund accounting, financial reporting, audit, transaction services, infrastructure, renewable energy, valuations, investment analysis or a comparable analytical role.

A strong finance or accounting background. A CFA or accounting qualification would be advantageous.

Good understanding of fund-management processes, including NAV, valuations, AUM, investor reporting, cash-flow forecasting, distributions, audit and governance.

Strong Excel and financial-modelling skills, including the ability to review models, analyse assumptions, reconcile outputs and perform scenario and sensitivity analysis. A modelling test may form part of the recruitment process.

Experience of analysing investment, fund or asset performance and creating high-quality investor or management information.

Experience with renewable energy, infrastructure, real assets, private markets, listed investment vehicles or multi-asset portfolios would be advantageous.

Octopus Energy chief Greg Jackson runs $17.4B firm with no HR, no bonuses, and no succession plan

Greg Jackson has built Octopus Energy into Britain's largest energy provider, serving 12 million homes across eight countries, without traditional corporate structures. The company operates with no HR department, no bonuses outside sales roles, and no succession plan. Jackson runs the 13,000-person firm through weekly rhythms: Monday meetings reviewing performance data and Friday all-hands sessions recapping achievements. The company has no intranet or newsletters, forcing employees to attend Friday gatherings to stay informed. Octopus had revenues of £13.7 billion last year and achieved a $9 billion valuation at its last fundraising. Every employee receives equity, and Jackson maintains direct customer contact, having met roughly 1,000 customers at recent events. The CEO refuses to discuss succession planning with his board, believing it creates harmful politics. His instruction to directors: "If I go under a bus, you will have to have several meetings, and then everything will be fine.

EU e-truck sector skeptical about CATL-Octopus battery-swapping plan

Octopus Energy and China's CATL have announced a joint venture to build a battery-swapping network for electric trucks across Europe, but the plan faces significant industry scepticism. Analysts warn that resistance from manufacturers and compatibility challenges could derail the initiative. European truck makers including Volvo and Scania are expected to oppose what they view as Chinese encroachment into their market. Critics argue that existing charging infrastructure already functions adequately, making battery swapping unnecessary. The joint venture must overcome substantial hurdles, particularly ensuring the system works across different truck models. Industry observers question whether manufacturers will adopt standardised battery systems required for swapping to succeed, potentially limiting the network's viability across Europe's diverse commercial vehicle fleet.

US-blacklisted Chinese firm CATL to install battery swap stations for electric trucks on UK roads

Contemporary Amperex Technology Co Ltd (CATL), a Chinese firm blacklisted by the US Pentagon as a "Chinese military company", will install battery-swapping stations for electric lorries across Britain from next year. CATL has denied any military links. The company is partnering with Octopus Energy, the UK's largest energy supplier, through a joint venture called Swaptopus. They plan to build 30 battery hubs across Europe by 2035, capable of supporting 300,000 electric trucks. The stations allow drivers to replace depleted batteries in under five minutes. The move could trigger security scrutiny, following a previous case where Chinese wind turbine manufacturer Ming Yang was blocked from UK projects after US national security concerns. CATL already operates over 300 battery-swapping stations in China, where electric models comprise more than 30% of the heavy-truck market.
