We help affirm this invitation by creating an inclusive, supportive environment where our team members are embraced exactly as they are. We’re looking for a commercially driven Senior Brand Marketing Manager to lead the development of bold, insight-led campaigns that build brand equity, drive customer acquisition, and deliver measurable growth. This role sits at the intersection of brand, acquisition, retention, social media, and creative execution, shaping 360° campaigns that connect with audiences across digital, retail, and experiential channels. You’ll play a key role in translating marketing strategy into high-impact creative that delivers both cultural relevance and commercial performance.

What You’ll Do

• Creative Strategy, Brand & Acquisition: Lead the development of integrated campaigns that strengthen brand positioning and build consumer trust while driving customer acquisition and revenue growth. Translate marketing objectives and audience insights into compelling, conversion-focused creative.

Ensure content has measurable KPIs to enable continuous testing, learning, and performance improvement over time.
• Campaign Delivery, Events & Trade Activation: Oversee end-to-end delivery of campaigns across digital, retail, and experiential channels. Own the brand marketing calendar, be the campaign manager and own briefs for all new launches and promotions. Work closely with Merchandising and E-commerce to align on trade planning and forecast; be reactive if needed to ensure trade stays on track to hit target. Align with the CRM team on messaging and approve all imagery and copy. Lead the creative execution of marketing events, activations, and trade-focused initiatives that drive traffic, engagement, and sales. Ensure campaigns are aligned to key trading moments, seasonal strategies, and commercial objectives. Ensure every campaign balances creative and commercial goals and is clearly targeted to the core customer. Own campaign performance wrap-up for each launch and promotion, consolidating cross-departmental insights and assessing performance against defined goals. Maintain a strong awareness of what’s happening in the market, keeping a close eye on competitors and the wider retail industry.
• Agency & Partner Management: Lead and manage relationships with creative, production, and media agencies, ensuring best-in-class output. Brief, guide, and challenge agencies to deliver work that meets brand standards and performance goals. Build a strong network of external partners, freelancers, and creators to scale creative output effectively. Monitor agency spend to ensure efficiency and minimise wastage, regularly reviewing partnerships and the balance of agency vs in-house.
• Team Leadership & Cross-Functional Collaboration: Inspire and lead a high-performing brand marketing, social, CRM, creative, and production team, fostering a culture of innovation and accountability. Work closely with merchandising and e-commerce to deliver joined-up campaigns. Act as a key connector between creative vision and commercial delivery.
