Job Description

Investment Associate

A London infrastructure investment manager is hiring an Associate into a modelling-led seat focused on battery storage.

This is a role for someone who wants to be the person the investment case runs through. You'll own the acquisition and fund models end to end, lead the underwriting on new opportunities, and pressure-test the revenue, capex and financing assumptions that decide whether a deal gets done. It sits close to the sharp end of the process: real ownership from day one, direct exposure to senior investors, and room to grow into wider deal execution as you prove yourself.

It's a strong moment to be doing this work. A large share of infrastructure capital is now moving into storage and grid-scale power, and this team invests directly into that shift, so the modelling you own turns into live deals rather than sitting in a pipeline.

What we're looking for:

  • 3 to 5 years in infrastructure, energy or project finance modelling, investment banking, private equity or advisory
  • Genuinely strong financial modelling, built from scratch and audited to a high standard, not just maintained
  • The judgement to move from the numbers to a clear investment view, and communicate it well
  • Someone who wants to own the modelling and build a career around it, and works well in a fast-paced, lean, high-ownership environment
  • Direct energy, power or storage experience is an advantage, though we'll consider a strong modeller from an adjacent background

Interested, or want to hear more confidentially, hit apply and I'll be in touch
