Senior Finance Business Partner in London

We're looking for an ambitious Senior Finance Business Partner to join us at a critical stage of growth. As we enter a stage of scaling rapidly, you'll play a central role in keeping our financial systems tight, helping us move fast without breaking things. You'll be hands-on with everything from FP&A to supplier contracts to investor reporting, collaborating closely with Operations, People, and Engineering. This role is based in our Kings Cross, London office and is 5-days a week in the office.

Responsibilities

• Support budgeting, forecasting, and cash flow modelling.
• Act as a trusted partner to teams across the business, owning purchasing workflows, spend management, and vendor onboarding.
• Prepare high-quality materials for board meetings, investor updates, and financial reporting.
• Support statutory and regulatory compliance in the UK and US, working with external accountants where needed.
• Identify and implement process improvements, automating wherever possible to help us scale.
• Drive cross-functional initiatives that improve financial visibility and operational efficiency (e.g. headcount reporting, capex tracking, cost optimisation).

Skills & Experience

• 5 years of experience in a finance, accounting, or FP&A role.
• Advanced Excel / Google Sheets skills; confident building, debugging, and owning financial models.
• Experience with Xero and tools like Pleo, Payhawk, Spendesk, Ramp, or similar.
• Highly organised and detail-oriented; you spot errors before others do.
• Proactive, pragmatic, and solutions-focused; you take initiative and make things better.
• Great communicator and confident working with cross-functional teams.

Nice to have

• Understanding of equity, cap tables, and fundraising processes.
• Experience in a hardware company and fast-paced environment.

This is a rare opportunity for someone with the right mix of experience, ambition, and appetite for building. But it's not for everyone. You will thrive here if you:

• See the strategic advantage that working side-by-side in an office can bring. We're moving quickly, and tight feedback loops matter.
• Are excited to set aside the playbook in favour of systems that actually fit our stage. You're not afraid to experiment, streamline, and question what's "standard".
• Use ChatGPT multiple times a day. Whether it's drafting investor memos, cleaning up spreadsheets, or pressure-testing a model, you see AI as a force multiplier.
• Champion transparency and believe finance shouldn't be a black box. You're excited to help others understand how our business runs and how their decisions impact the health of the business.

Compensation & Benefits

• £82,000 – £105,000 annual salary, depending on experience, skills, and location.
• Competitive stock options, you're not just part of the journey, you will own a piece of it.
• Work from our HQ in King's Cross, right in the middle of London's buzzing AI scene.
• Live within 45 minutes of the office? Perfect. Live within 20 minutes? We'll add an extra location bonus to your salary.
