5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Experiment Design & Methodology Proposes designs for review, executes pre-defined tests. Designs and executes standard A/B tests independently, seeks feedback on complex ones. Designs and implements complex multi-variate and split URL tests, defines methodology for owned funnel stages, mentors others.
Resource Allocation (Time & Tools) Follows task priorities set by supervisor. Manages own time for assigned projects, proposes tool usage within existing budget. Prioritises experiments within owned funnel stage, recommends new tools/resources up to £5K, advocates for engineering time.
Stakeholder Communication Reports results to supervisor, asks for help with stakeholder questions. Presents results to immediate team, answers routine stakeholder questions. Presents experiment results and strategic recommendations to cross-functional leads (Product, Engineering), manages expectations, influences prioritisation.
Data Interpretation & Action Analyses data with guidance, identifies basic trends. Independently analyses data, draws conclusions, proposes next steps for routine experiments. Interprets complex data sets, identifies root causes of performance changes, makes data-backed strategic recommendations for funnel optimisation, validates data integrity.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Activation Rate Improvement
The percentage increase in new users completing a key 'activation' event (e.g., first purchase, first project creation, inviting a friend).
Target · Increase activation rate by 10-15% QoQ for your owned funnel stage.

If our current activation rate is 30%, you'd aim to get it to 33-34.5% within a quarter through your experiments. For instance, a test on the onboarding flow might lift it from 30% to 32%.

Retention Rate Lift
The percentage increase in users returning or remaining active after a specific period (e.g., 30-day retention).
Target · Improve 30-day retention by 5-8% for targeted user segments.

If 30-day retention for a segment is 40%, you'd aim for 42-43.2% by optimising post-activation emails or in-product nudges. A successful experiment might move it from 40% to 41.5%.

Experiment Win Rate & Learnings
The proportion of experiments that yield a statistically significant positive result, balanced with clear, documented learnings from all tests (wins and losses).
Target · Achieve a win rate of 20-25% for statistically significant tests, and ensure 100% of experiments have documented insights.

Out of 10 experiments in a month, 2-3 should show a clear positive impact. Crucially, for the other 7-8, you'll have a clear 'why it failed' and 'what we learned' documented in our experimentation log.

Funnel Velocity Improvement
Reducing the average time it takes for a user to move from one key funnel stage to the next (e.g., from signup to first purchase).
Target · Decrease average time to activation by 10-15%.

If it currently takes new users 7 days to reach their 'Aha! Moment', you'd aim to get that down to 6-6.3 days by streamlining the initial user experience or improving early communication.

Experimentation Cadence & Quality
Your ability to consistently generate high-quality, testable hypotheses and push experiments through the pipeline efficiently, even when resources are tight. It's about smart testing, not just busy work.
  • You're regularly proposing well-researched experiment ideas in our weekly growth meeting. Your experiment briefs are clear, concise, and include solid hypotheses. You're not just running tests, you're running meaningful tests that teach us something new, even if they 'fail'.
Cross-functional Influence
How effectively you can work with Product, Engineering, and other Marketing teams to get your experiments prioritised and implemented. This means making a compelling case with data and clear business impact.
  • Product teams are actively seeking your input on new feature launches. Engineering is generally happy to help with your requests (or at least not dreading them). You're seen as someone who brings solutions, not just problems, to the table. You can clearly articulate the 'why' behind your requests, making it easy for others to agree.
Mentorship & Knowledge Sharing
Your willingness and ability to help junior team members grow, share your insights, and contribute to the overall knowledge base of the growth team.
  • Junior analysts are coming to you for advice on experiment design or data analysis. You're leading internal workshops or lunch-and-learns on new tools or methodologies. Your documentation is clear enough that others can pick up your work without constant questions. You're actively reviewing code or experiment plans for others.
Data Integrity & Tracking Vigilance
Your dedication to ensuring our analytics tracking is accurate and reliable, spotting discrepancies, and proactively working to fix them.
  • You're the first to flag when a dashboard looks 'off' or when a new product release might break existing tracking. You're regularly auditing event data and working with data engineers to maintain data quality. You don't just use the numbers
  • you question them.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Seeing Tangible Impact

You'll get a real kick out of seeing a dashboard metric jump because of an experiment you designed. That direct line from your work to business results is what gets you going.

Watching the activation rate for new sign-ups climb by 12% after you tweaked the onboarding flow, and knowing that's directly because of your work.

Solving Puzzles with Data

You love digging into messy data, finding hidden patterns, and figuring out 'why' users behave a certain way. It's like being a detective, but with numbers.

Uncovering that users who complete step 3 of onboarding within 24 hours have a 3x higher retention rate, and then designing experiments to push more users to hit that milestone.

Continuous Learning & Experimentation

The idea of constantly trying new things, learning from failures, and iterating quickly excites you. You thrive in an environment where 'we tried it, it didn't work, now what?' is a common phrase.

You're always reading up on new growth tactics, testing them out, and sharing your findings with the team, even if most of them don't pan out.

What frustrates people
  • The 'HiPPO Effect': Spending weeks on data-backed hypothesis, only for a senior exec to kill it based on a gut feeling.
  • Engineering Bottlenecks: Having a backlog of high-impact experiments that can't be built because engineering is swamped.
  • Attribution Hell: Endless debates over who gets credit for a conversion because the tracking is messy or the model is flawed.
  • Chasing Statistical Significance: Watching a promising A/B test run for weeks on a low-traffic page, unable to reach a conclusive result, tying up resources.
  • Data Plumbing & Janitorial Work: Realising that a huge chunk of your time isn't on clever experiments, but on debugging tracking scripts and cleaning messy data.
  • Explaining 'Why' to Stakeholders: The repetitive task of explaining why a test with a 94% confidence level isn't 'close enough' to declare a winner.
What this role does not give you
  • A predictable, routine day-to-day where every task is clearly defined and follows a set process.
  • Guaranteed success for every experiment you launch; most will fail, and that's part of the job.
  • Complete control over resources; you'll often have to make a strong case for what you need.
  • A quiet, solitary environment; you'll be collaborating and influencing constantly.

8Who you work with

This role directly impacts our core growth metrics, specifically around user activation, engagement, and retention. Your experiments will directly influence product features, marketing messaging, and overall customer journey design. Get it right, and we see healthier user numbers and better LTV. Get it wrong, and we're just spinning our wheels, wasting budget on things that don't work.

Inside the business
  • Product Managers (especially those owning specific features)
  • Engineering Team (for experiment implementation)
  • Data Analysts (for deep dives and tracking validation)
  • Content Marketing Team (for copy and creative assets)
  • Sales Leadership (for lead quality feedback)
Outside the business
  • A/B Testing Platform Vendors
  • Marketing Automation Tool Providers

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • Roughly 5-8 years of hands-on experience in a dedicated growth marketing or experimentation role, where you've owned parts of a customer funnel.
  • A proven track record of designing, running, and analysing A/B tests that have led to measurable improvements in key metrics.
  • Solid experience with at least one major web analytics platform (GA4, Mixpanel, Amplitude) and one A/B testing tool (Optimizely, VWO).
  • The ability to write clear, concise experiment briefs and communicate complex data insights to non-technical audiences.
  • A genuine passion for data-driven decision making and a healthy scepticism towards assumptions.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced SQL & Data Warehousing

As our data grows and becomes more complex, simply pulling basic queries won't cut it. You'll need to join more tables, handle larger datasets, and understand how our data warehouse is structured to get truly insightful data for your experiments. The ability to self-serve complex data requests will become crucial.

Window Functions · Common Table Expressions (CTEs) · Data Modelling Basics · Performance Optimisation

  • This week: Pick one complex report you currently rely on a data analyst for and try to build the SQL query yourself.
  • This month: Complete an online course on advanced SQL (e.g., on DataCamp or Udemy) focusing on window functions and CTEs.
  • Month 2: Work with a data engineer to understand the structure of our core marketing data tables and how they relate.
  • Month 3: Document a 'cheat sheet' of advanced SQL queries for common growth analysis tasks and share it with the team.

Quick win: Start using CTEs in your everyday SQL queries to make them more readable. It's a small change with a big impact on clarity.

11Staying current once you are in

What people here do to keep up
  • Regularly attending industry webinars and virtual conferences on growth marketing, experimentation, and product-led growth.
  • Subscribing to leading growth blogs and newsletters (e.g., Reforge, GrowthHackers, Lenny's Newsletter) to stay current on trends and best practices.
  • Actively participating in online growth communities or local meetups to share knowledge and learn from peers.
  • Taking advanced courses on SQL, data visualisation, or behavioural economics to deepen your analytical toolkit.
  • Experimenting with new AI tools and prompt engineering techniques in your personal or side projects.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, growth hacking can be a grind. The endless ad copy variations, the deep dive into competitor strategies, the sheer volume of data. What if you could spend less time on the tedious bits and more on the big, impactful ideas? Good news: AI can help you do exactly that.

We're not talking about replacing your brain; we're talking about giving you a seriously powerful co-pilot. AI tools can automate the grunt work, supercharge your creative output, and help you spot patterns in data that would take you days to find manually. Think of it as having an army of junior analysts and copywriters at your fingertips, letting you focus on the strategic stuff.

Ad Copy & Variant Generation

Use AI tools like Jasper or Copy.ai to churn out dozens of ad copy, headline, and landing page variants in minutes. This means you can rapidly increase the volume of testable ideas, overcome creative blocks, and find winning messages much faster than doing it all manually. Honestly, it's a game-changer for experiment velocity.

Predictive Churn Analysis

Feed your user behaviour data into AI models to predict which users are at high risk of churning. This isn't just a fancy report; it allows you to launch proactive, targeted retention campaigns before those users are lost. Imagine knowing who to focus on before they even think about leaving – that's powerful stuff.

Competitor & Trend Synthesis

AI-powered market intelligence tools can constantly monitor competitor websites, ad campaigns, and pricing changes. Instead of manually checking, AI synthesises this data into a concise weekly brief, highlighting threats and opportunities you might have missed. It's like having a dedicated research assistant, but much faster and cheaper.

Experiment Result Summarisation

You've run the experiment, crunched the numbers, and now you need to explain it to the wider team. Feed your raw experiment data and analysis into an LLM (like ChatGPT or Claude) and ask it to generate a concise, business-friendly summary for stakeholders. It translates statistical jargon into clear business impact, saving you ages on report writing.
