Senior Marketing Campaign Manager in London

Zymix is a Gen‑Z social super‑app launching in the UK and Europe — combining instant messaging, short video, social, and payments in one platform. We're building the cultural home for the next generation of UK and European Gen‑Z, starting with major cities and university communities. We’re pre‑launch, fast‑moving, and looking for marketers who can build campaigns from zero — not just run them.

The Role

We’re hiring a Senior Marketing Campaign Manager to own integrated campaigns across the UK, with a particular focus on large‑scale activations in London, Manchester, and other priority cities, alongside university student marketing. You’ll lead campaigns end‑to‑end: from concept and brand narrative through to media buying, on‑the‑ground execution, and performance reporting. This is a hands‑on senior IC role with a small team (1–3 reports). You’ll work closely with our Social, Events, PR, and Content & KOL functions to make sure every campaign hits both brand and growth targets.

What You’ll Own

• Integrated campaign strategy & delivery — Lead end‑to‑end campaigns tied to product launches, seasonal moments, and Zymix’s growth roadmap. Own the brief, the budget, the timeline, and the outcome.
• City‑level activations — Plan and deliver flagship activations in London, Manchester, and other Tier‑1 UK cities. Pop‑ups, launch events, sponsored moments, cultural tie‑ins.
• University student marketing — Build Zymix’s playbook for UK universities: freshers’ week activations, society partnerships, on‑campus events, and student creator collaborations.
• Brand + Performance dual‑track — Make sure every campaign builds Zymix’s brand equity and delivers trackable acquisition / engagement results. Define KPIs upfront, instrument tracking, report honestly.
• Cross‑functional leadership — Partner with Social, Events, PR, Content & KOL, and Product to align messaging, assets, and timing. Brief and manage external agencies and production partners.
• Team management — Lead and grow a team of 1–3 (campaign executives / coordinators). Set standards, give feedback, develop talent.

What You’ll Bring

Must‑haves

• 5+ years in marketing campaign roles, with at least 2 years at senior / lead level.
• Direct experience at a social, consumer tech, or app‑first company — you understand how growth, product, and marketing interact.
• Hands‑on experience delivering large‑scale activations in London, Manchester, or comparable UK cities — you’ve personally been on the ground, not just signed off decks.
• Proven track record running university / Gen‑Z student marketing campaigns in the UK (freshers, student societies, university events, student creators).
• Strong brand‑building instinct: you can spot when a campaign is on‑brand vs. off‑brand, and you protect the brand even under growth pressure.
• Solid performance marketing fluency: you can set KPIs, read dashboards, work with paid social / influencer / referral channels, and report results that are genuinely trackable — not vanity metrics.
• Experience managing budgets of £500k+ and external agencies.

Nice‑to‑have

• Experience launching a consumer app or new brand into the UK market.

How We’ll Know You’re the One

• You can walk us through a campaign you’ve personally led, from brief to results, with real numbers.
• You’ve made hard trade‑offs between brand and performance — and can articulate how you decided.
• You’ve recovered from a campaign that didn’t go to plan, and can tell us what you changed afterwards.

Why Zymix

• Build a category‑defining product for UK and European Gen‑Z from day one.
• Real ownership — pre‑launch means your work shapes the brand, not just optimises it.
• Small senior team, direct access to leadership, fast decision‑making.
• Competitive salary (DOE) + benefits package.
