Head of Marketing – Jewells (London Support Centre)Location: London

About Jewells

Jewells isn’t your typical jewellery brand. We create waterproof, sweat-proof pieces designed to be lived in every day. From personalised Memory Stacks to professional piercing services, we’re redefining what it means to shop jewellery in the modern world. Fast-paced, fashion-forward, and unapologetically accessible, Jewells is setting a new standard – jewellery that goes where you go and tells your story along the way.

The Role

We’re looking for a dynamic, commercially driven Head of Marketing to lead and scale Jewells’ brand presence across every channel. Based at our London Support Centre, you’ll own the end-to-end marketing strategy and execution – from advertising and campaigns to cultural activations – with a laser focus on delivering measurable results.

You’ll directly manage a team, driving collaboration with the wider business to maximise revenue across stores, e-commerce, and social media. This role is as strategic as it is hands-on: you’ll shape the big picture while getting into the detail of shoots, partnerships, and campaign execution.

Perfect for someone who has built (or rebuilt) marketing functions in fast-paced retail environments – fashion, jewellery, beauty or lifestyle – and knows how to turn brand energy into commercial growth.

What You’ll Own

Marketing Strategy & Execution

• Lead, evolve, and deliver Jewells’ marketing strategy across paid, owned, and earned channels.
• Build and execute seasonal campaign calendars aligned to business and revenue goals.
• Own marketing performance reporting, with a sharp focus on ROI, customer acquisition, and retention.
• Manage, mentor, and inspire the Content Manager and Brand & Marketing Manager, ensuring the team delivers at pace and to a high creative and commercial standard.
• Oversee influencer, partnerships, CRM/email, and paid digital activity through effective delegation and collaboration.
• Build a strong team culture of accountability, creativity, and speed-to-market.

• Shape our CRM and retention approach — from lifecycle marketing to customer journeys.
• Own the creative direction and organisation of shoots, events, and activations, ensuring campaigns feel fresh and commercially impactful.
