WHO WE ARE

With clubs across Soho, Marylebone, Liverpool Street, and Canary Wharf, UNTIL brings the industry's very best together under one roof.

THE ROLE

The Growth Marketer is responsible for owning UNTIL's paid acquisition, conversion, and growth experimentation engine. This is a hands‑on individual contributor role, sitting at the intersection of performance marketing, web, and data. You'll own the channels, run the tests, and drive the decisions that move member and consumer growth across our marketplace. You won't be waiting for a brief or a process. You'll be building the system. This role is not about getting it right first time. It's about moving fast, learning faster, and compounding those learnings into growth. You'll use AI tools not as a shortcut but as a genuine force multiplier, building, automating, and iterating at a pace that wouldn't be possible otherwise.

WHAT YOU OWN

• Paid Performance Marketing
  • Own and manage paid channels end-to-end, including Meta and Google
  • Build, test, and optimise campaigns across both member and consumer audiences
  • Manage agency relationships and hold partners accountable to performance
  • Run a disciplined test‑and‑learn programme across landing pages, funnels, and creatives
  • Design experiments with clear hypotheses, proper measurement, and honest post‑mortems
  • Own CRO across key acquisition journeys, from ad click to conversion
• Website & Growth Channels
  • Own the growth layer of the website, working closely with our web developer and SEO freelancer
  • Deploy and iterate on landing pages without needing to hand off every change
  • Identify and develop new growth channels as the business scales
• Data & Reporting
  • Build dashboards and reporting to track performance across paid, organic, and owned channels
  • Own attribution and funnel analytics to surface where growth is coming from and where it's leaking
  • Feed insights back into campaign decisions, creative briefs, and channel strategy

WHO YOU ARE

You're an analytical, self‑sufficient growth marketer who gets things done, using every tool available to move faster. You are someone who:

• Is agentic by default. You don't wait to be told what to optimise. You spot the gap, form a hypothesis, and go.
• Is genuinely AI-forward. You use AI tools daily to work faster, test more, and do more with less. This isn't a nice‑to‑have. It's how you operate.
• Thinks in funnels and systems. You understand the full acquisition journey and know where to pull the levers.
• Has a rigorous test‑and‑learn mentality. You design proper experiments, not gut‑feel tweaks, and you document what you find.
• Is commercially grounded. You tie everything back to acquisition, utilisation, and revenue. Not vanity metrics.
• Owns the outcome, not just the task. You run a tight experiment backlog and nothing gets lost between tests.
• Is a strong cross‑functional collaborator. You work fluidly with the Marketing Manager, creative team, sales team, and consumer team, contributing without losing pace.
• Can manage agency partners well. You know how to get the best out of external teams and keep them sharp.

YOU LIKELY HAVE

• 4‑5 years in growth, performance, or digital marketing in a startup or scale‑up environment
• Hands‑on experience running Meta and Google campaigns with real budget ownership
• Comfort working with data: analytics platforms, attribution, funnel reporting
• Experience running A/B tests and landing page experiments
• A working knowledge of SEO and CRO principles
• Experience working with or managing agencies and freelancers
• A track record of using AI tools to increase your output and speed
