Management Accountant - High-Growth Health Tech Start-up (London)

About the Role

We're a venture-backed health-tech business on a mission to help people take control of their health, with strong growth behind us and big plans ahead. As we build out our finance function, we're looking for a commercially minded Finance professional to help shape how it operates.

Reporting to the Finance Lead you'll own day-to-day finance and provide support across the business. You'll work closely with our B2B team which is a fast-growing side of the business with big expectations ahead.

We're a small team that supports each other, but we also need someone who can work independently and take the initiative. You'll have real ownership of your work, with the freedom to improve how things are done.

It's a role you can make your own, with broad exposure across the business and room to grow, all while doing genuinely meaningful work.

Responsibilities

• Run the day-to-day finance function, keeping things accurate, timely, and well-controlled.
• Own the month-end close and monthly management accounts, including balance sheet reconciliations and revenue recognition.
• Manage cash flow.
• Deliver monthly reporting and commercial analysis, including variance analysis and ad hoc deep-dives, to present performance and insight clearly.
• Partner closely with the B2B team, supporting their finance needs, ensuring on-time payment and no revenue leakage, with revenue reporting at the contract level.
• Support the budgeting, forecasting, and FP&A cycle, partnering with the Finance Lead on planning and decisions.
• Manage the annual audit, acting as the main point of contact for auditors and ensuring a smooth close.
• Build and improve the processes and controls the finance function needs as the business scales.
• Work across teams to provide insight and support decision-making.

The ideal candidate

• Takes ownership, spotting what isn’t working and driving it to a better outcome without being asked
• A sharp critical thinker who questions assumptions and digs into the “why”
• Works independently and makes the call, while knowing when to pull in support
• Commercially-minded, linking the numbers to what’s happening in the business
• Adaptable, staying effective as priorities shift
• Communicates clearly with finance and non-finance people alike
• Organised and reliable, juggling priorities and hitting deadlines

Technical skills and experience

• Part or fully qualified accountant (ACA, ACCA, or CIMA)
• Strong understanding of accounting principles, financial reporting, and controls
• Proven experience in owning a month-end close end-to-end
• Advanced Excel skills
• Experienced in using accounting software (Xero preferred)
• Experience across the FP&A cycle: budgeting, forecasting, and variance analysis
• Relevant industry experience in a fast-paced startup or scale-up environment

Why Second Nature?

The Challenge

Obesity has become a global epidemic; in the UK, we spend £9 billion a year alone on diseases like type 2 diabetes (that’s 10% of the NHS budget). What’s shocking is most of this is preventable – through sustained lifestyle and habit change.

Enter Second Nature.

We’re here to help people take control of their health. By bringing together behavioural science, technology, and incredible people, our grand mission is to eradicate the global epidemic of chronic lifestyle diseases once and for all.

Our digital habit change programme – delivered digitally through mobile and web apps – helps people to improve their lifestyle, lose weight, and ultimately reduce their risk for conditions such as type 2 diabetes.
