Senior Marketing Executive (Growth & Campaigns) - Ref: SRMRKTEXC - Q1 - 2026

Are you a hands-on marketing generalist with experience across both paid and organic channels? Do you enjoy owning work end-to-end, spotting gaps, and making things happen without being micromanaged? Do you want to work on meaningful projects for some of the world's most recognisable brands, and actually see your work out in the world?

If that sounds like you, keep reading.

Who are we? We're Magnetic, an independent full-service creative agency with offices in London and Istanbul, and plans to expand further in 2026. When we say full-service, we mean it. We work across brand, design, marketing, digital, events and experiences, partnering with ambitious organisations navigating complexity, change, and growth.

Our client roster includes Meta (Facebook, Instagram, WhatsApp), Diageo, Save the Children, and other global and scale-up brands. We're a close-knit, senior team that values clarity, quality, and calm execution, even when things move fast.

The Role (what This Is Really About)

This is a hands-on, high-autonomy role. You will be the primary owner of marketing execution across multiple channels, working on client campaigns as well as Magnetic's own growth and brand presence.

You'll be expected to:

• Operate confidently without over-detailed briefs
• Translate direction into action
• Spot gaps, propose solutions, and move work forward
• Balance creativity with commercial thinking

This role suits someone who enjoys responsibility, variety, and making things happen, rather than waiting to be told what to do.

Interviews: January / February 2026

Start date: As soon as possible

Uniqueness makes us Magnetic. Magnetic is built on diverse perspectives, curiosity, and mutual respect. We value people who bring their authentic selves to work and believe that diversity drives better thinking, creativity, and outcomes.

What We're Looking For

The most important thing is mindset. We're looking for someone who brings a start-up mentality to their work: proactive, resourceful, and comfortable rolling up their sleeves. You should be a strong generalist who can move between channels and projects confidently, without sacrificing quality.

Key requirements:

• Experience in a marketing or growth-focused role (agency or in-house)
• Hands-on knowledge of paid ad platforms (Meta, LinkedIn, Google Ads)
• Experience managing organic social channels
• Familiarity with CRM and email platforms (HubSpot, Mailchimp or similar)
• Strong copywriting and verbal communication skills
• Excellent organisational and prioritisation skills
• Comfortable working independently and as part of a team
• Excellent written and spoken English

Nice to have (but not essential):

• Marketing or communications-related degree
• SEO knowledge
• Experience working with creative teams or agencies

What Success Looks Like In The First 90 Days

• Client and internal campaigns are running smoothly across paid, organic, and email
• Magnetic's own channels are active, consistent, and on-brand
• Reporting is clear, reliable, and useful to leadership
• You're confidently proposing ideas and improvements, not just executing tasks
