About the role (What you’ll be doing)

As a Performance Marketer, you will be a hands‑on IC sitting within the International Launch Team, working directly under the Global Head of Performance and alongside our Staff Performance Marketer (Search & Analytics). You’ll be a key part of the central buying function, responsible for running paid media across international markets from day one.

You’ll start with Meta as our biggest spending channel, then expand across TikTok, Search, and others as the function grows. There’s minimal approval friction here. If you have a good idea, you can test it. The feedback loop is tight and the learning is real.

You’ll:

• Own and optimise paid media campaigns across Meta, with expanding scope into TikTok and Search.
• Set up paid media accounts from scratch in new markets - building campaign structure, tracking, and creative testing frameworks from the ground up.
• Run a consistent test‑measure‑learn cycle across creative and campaign setup to keep improving performance.
• Work within established playbooks and pressure test them - flagging what’s working, what isn’t, and why.
• Turn performance data into sharp creative briefs and clear optimisation plans.
• Analyse what’s working across creative, targeting, and landing page experience - and act on it.
• Build clear performance reports that track results by channel, campaign, and creative.
• Keep tracking clean and accurate across platforms using pixels, UTMs, and event‑based measurement.
• Explore and apply AI tools to create efficiencies in day‑to‑day workflows and speed up the test‑and‑learn cycle.
• Stay across platform changes and best practices to keep strategies sharp.
• Work cross‑functionally with analytics and growth teams to surface insights and spot new opportunities.

About you (Who you are)

You’ve got 3‑5 years in performance marketing with serious hands‑on time on Meta. You think about creative as the lever, not an afterthought. You’re comfortable pulling data and turning it into a point of view and you’re curious enough to keep pushing on what’s possible.

You’ll likely bring:

• 3‑5 years of performance marketing experience with a heavy focus on Meta / Facebook Ads.
• Strong instincts for direct response creative - what works, how to test it, and how to scale it.
• Experience managing ad accounts spending meaningful budgets, ideally across multiple markets or brands.
• Solid understanding of campaign setup, attribution, pixel and event tracking.
• Analytical chops - you can read performance data and know what to do with it.
• A genuine curiosity about AI tools and how they can make you faster and smarter.
• Comfort working across multiple channels (TikTok and Search experience is a bonus).
• Experience in regulated categories (health, finance) is a plus but not required.
• Based in London and able to be in the Old Street office 3 days a week.

Why join Eucalyptus?

• Real scale, real fast - you’ll be running campaigns across 6‑7 figure monthly budgets across multiple international markets.
• Set things up from scratch - this isn’t just inheriting a running account. You’ll stand up new markets from zero, which is rare experience at this level.
• Creative‑first culture - we believe creative is the most important part of marketing, and you’ll be in an environment that takes it seriously.
• Direct access to senior leadership - you’ll work shoulder‑to‑shoulder with the Global Head of Performance and a Staff‑level specialist from day one.
• Fast feedback, low friction - good ideas get tested quickly here. No months of approvals to move forward.
• Global exposure - running campaigns across markets that most marketers never get near.

Perks and benefits

• Hybrid working (3 days/week in our Old Street office).
• Annual professional development budget.
• 25 days holiday + bank holidays.
• Wellness allowance.
• Enhanced parental leave (20 weeks paid for primary carers).
