About the Role

This is a truly career defining role for someone passionate about the commercial side of Finance looking for an opportunity to play a role in growing the international consumer business

We’re looking for creative big thinkers with small egos to achieve our ambitious plans. You’ll bring experience in a commercial, financial or analytical role, and demonstrate a proactive, can-do attitude

We’d prefer you to have worked within a digital, e-commerce, technology or retail environment but we can flex on this given your ability to work with pace and energy within a growth environment

You will be familiar with the measurement and modelling of marketing ROI using various measurement techniques, and calculation of customer economics metrics (paybacks, LTV : CAC ratios)

A team player with a ‘roll your sleeves up’ attitude, you’ll be used to using your commercial awareness to think laterally and solve problems, and will have a passion for making meaning out of data

Similarly, it’s vital that you bring an innate ability to distil and communicate results of complex analysis clearly and effectively to all levels of the business

Working independently within tight deadlines, you’ll have the ability to think creatively to identify and enhance both commercial and customer-oriented opportunities

You should have experience of modelling and forecasting and an understanding of broader analytical techniques as well as writing queries in SQL

Our comparative advantage is that we learn faster than the competition, and the Commercial Finance team is key to driving this discovery cycle. We dig deeper, we think insight not numbers, we articulate complexity clearly and with confidence

As Senior Commercial Finance Manager - Marketing, you’ll provide high quality, actionable insight to support our International Consumer business

You’ll develop strong relationships with business stakeholders at all levels whilst deep diving into performance drawing on your network within other departments such as Commercial, Data Science and Supply

Our department is ever evolving, and so you will play an important role in enabling a culture of continuous improvement, working closely with the Data team to devise innovative ways to access insight

Act as lead finance partner for our Growth, Engagement & Brand Marketing teams, shaping strategy with clear commercial insight and challenging thinking to drive performance

Own and evolve weekly marketing trading reporting, delivering fast, accurate insights that influence decision-making and maximise return on marketing & promo spend

Steer capital allocation decisions across brand, performance and promotional channels and markets, optimising how and where we invest, to achieve business goals

Enhance ROI modelling, measurement and tracking, working with Data Science and Brand Insights to understand incrementality of spend, and accurately forecast and measure returns

Lead innovative optimisation projects with Growth and Data Science, leveraging modelling, experimentation, customer segmentation and funnel analytics to unlock growth

Create high-impact narratives and presentations, distilling complex performance drivers into compelling stories on customer value, payback and long-term impact

Shape multi-year marketing financial plans, aligning resources to strategy and challenging teams to think bigger and bolder

Champion the evolution of Commercial Finance, embracing new technologies (including AI), improving ways of working and sharing best practice

In return for your hard work, we’ll provide you with opportunity for progression and, should you choose, we will support you in studying for finance qualifications as you play your part in disrupting and defining a product that is changing the way we travel and inspiring millions people all over the world to make more environmentally sustainable travel choices every day
