We’re looking for a curious and highly analytical growth marketing manager to discover and scale our next multi-million-pound acquisition channels. You will be the engine of our new channel experimentation, systematically identifying, testing, and validating opportunities that sit outside our core performance channels. From CTV and audio to direct mail and partnerships, you will have the autonomy and budget to find our next major growth lever.
This is not a typical marketing role focused on optimising existing campaigns. This is a 0-to-1 opportunity for a true builder. You'll be a scientist, strategist, and operator all in one, with a clear mandate to test, fail, learn, and scale. Your successes will directly contribute to diversifying our marketing mix and securing our long-term, sustainable growth.
This hybrid role is based three days per week in our London HQ.
What you’ll do
- Own the experimentation pipeline – Build and manage a rigorous, high-velocity testing framework to identify, prioritise, and execute growth experiments across a wide range of potential new channels.
- Launch and scale new channels – Take validated ideas from initial test to fully-fledged acquisition channels, developing the playbook, managing budgets, and building the business case for further investment.
- Manage the full experiment lifecycle – Run the end-to-end process for each test: from hypothesis generation and financial modelling to creative briefing, technical setup, execution, and post-campaign analysis.
- Champion disciplined measurement – Define clear "kill or scale" criteria for every experiment. Utilise geo-lift tests, incrementality measurement, and cohort analysis to prove the true impact of your channels.
- Manage an experimentation P&L – Own and deploy a dedicated seven-figure experimentation budget, allocating capital efficiently to the highest-potential opportunities and reporting on portfolio performance.
- Partner cross-functionally – Work hand-in-hand with data to design tests, creative to produce bespoke assets, product to build required landing pages, and finance to model potential outcomes.
Who you are
- 4+ years in a growth, performance, or user acquisition role within a fast-growing tech or DTC company. Direct experience in launching and scaling new channels is essential.
- Hypothesis-driven and deeply analytical. You are comfortable building a financial model from scratch, can separate correlation from causation, and live by the principle of statistical significance.
- A T-shaped marketer with a broad understanding of many channels but a deep, hands-on expertise in at least one or two (paid social, search, affiliates, etc.).
- Resourceful and biased to action. You know how to get a test live quickly and creatively, even without a perfect playbook or existing infrastructure.
- Fluent in data analysis. Proficiency with tools like Looker/Tableau and Excel/Google Sheets is a must. Basic SQL knowledge is a strong advantage.
- Thrive in ambiguity and are comfortable with failure. You see a failed test as a valuable learning opportunity, not a setback.
- An excellent project manager, able to juggle multiple experiments and stakeholder relationships simultaneously without dropping the ball.
- A compelling communicator who can build a powerful narrative around data to influence decision-making and secure buy-in for new initiatives.
