Our customers, including Microsoft and Google, trust us to help them avoid greenwashing.

We’re looking for doers with a bias to action. Our team is brilliant and cares (a lot).

Join us for the most impactful role of your career—and the best job you’ve ever had.

Things you'll do in this role:

• Own day-to-day finance (month-end close, AP/AR, bank reconciliations, payroll coordination) and revenue (invoicing, billing, collections, revenue recognition) operations.

• Develop and maintain the company's financial models, forecasts and board-level reporting pack, partnering with the Chief of Staff and leadership team on runway planning, pricing analysis and fundraising preparation.

• Be the first dedicated finance hire: own the relationship with external accountants, auditors and tax advisors, strengthen existing controls and workflows, and make sure our finance processes keep pace as the company scales.

Things we're looking for:

• Qualified accountant (ACA, ACCA, CIMA or equivalent) with hands-on experience running finance in a high-growth startup or scale-up—you've improved and scaled processes, not just inherited them.

• Comfortable across the full stack: you can close the books on Monday, build a three-statement model on Tuesday and chase down a late invoice on Wednesday. Strong modelling skills and the ability to present complex analysis simply to a non-finance audience.

• Bias to action and comfort with ambiguity.

This role isn't for you if:

• You want a remote job. We value in-person collaboration and spend three days a week in the office.

• You prefer staying within your area of expertise and operating in structured environments. We navigate ambiguity at extreme pace and everyone is a generalist.

• You're looking for a short term gig. We're building for the long term and looking for people ready to grow with us for 5-10 years.
