Human Resource Administrator jobs in United Kingdom

We're Forest. You know, those shared ebikes in London that look like trees. We're London's most sustainable shared ebike operator. We bridge the gap between affordability and sustainability, using advertising revenue to offer all users 10 minutes of free cycling every day. Our mission is to help cities move greener-and we're growing fast. We recently closed the first round of our Series B and are set to continue our ambitious expansion plan. Last year, our loyal user base completed over 9 million rides.

We're looking for a dynamic FP&A Manager to join our small, cross-disciplinary finance team, where everyone contributes beyond their core remit. This is a fantastic opportunity to shape FP&A from the ground up in a fast-paced, entrepreneurial environment.

As FP&A Manager, you will be responsible for building and running our financial planning and analysis capability. You'll own forecasting, budgeting, and performance reporting across the business, ensuring that our leadership and functional teams have the insights needed to make informed decisions. You'll also play a key role in cash flow management, ensuring our growth is both ambitious and sustainable.

• Own the company's financial model and rolling forecasts, ensuring accuracy and relevance.
• Build and maintain budgeting processes for each team, working closely with department heads.
• Drive scenario analysis to inform strategic decisions and fundraising readiness.

• Deliver monthly performance dashboards and variance analyses to the leadership team and Board.
• Identify trends, opportunities, and risks, and make recommendations to improve financial outcomes.
• Partner with the CFO to present insights to investors and stakeholders.

• Manage cash flow forecasting and reporting at both a company-wide and departmental level.
• Support working capital optimization and proactive treasury management.
• Provide analysis to support investment in growth initiatives.

• Work directly with functional leaders (Growth, Product, Operations, People, etc.) to align resources with company goals.
• Translate financial data into actionable insights for non-finance stakeholders.
• Support ad-hoc strategic projects, from pricing to unit economics to new market entry.

• Contribute to ad-hoc projects and operational finance tasks, reflecting the nature of working in a lean team at a scaling company.
• Help design and improve processes, systems, and tools for financial reporting and planning.

Must-Have

• Experience in FP&A, finance, or strategy, ideally in a high-growth scale-up, startup, or dynamic environment.
• Strong financial modeling skills (Excel/Google Sheets; familiarity with Xero and FP&A tools is a plus).
• Excellent understanding of budgeting, forecasting, and cash flow management.
• Ability to communicate financial concepts clearly to non-finance stakeholders.
• Proactive and analytical mindset with attention to detail, balanced by commercial pragmatism.
• Comfortable operating in ambiguity and rolling up your sleeves, working cross-functionally in a small-team setting

Nice-to-Have

• Prior experience in a Series B+ startup / scale-up environment.
• Exposure to investor relations and board reporting.
• Knowledge of Tech startups & recurring revenue business models

Office at a WeWork in Moorgate

• The chance to build FP&A from scratch in a fast-growing business.
• High visibility and close collaboration with the CFO and leadership team.
• A dynamic, entrepreneurial culture where your work has immediate impact.
• Competitive salary and benefits.
