Social Media Marketing Specialist in London

THE JESSICA McCORMACK BRAND
Renowned diamond jeweller Jessica McCormack designs exceptional jewellery for the modern woman, creating heirlooms for future generations. Artfully blending modernity and timelessness, her mission is to create jewellery that generations of women will wear and adore. Since launching in 2008, the brand has become known for effortlessly melding the traditional and the contemporary, combining Georgian techniques and expert craftsmanship with modern-day design influences, eschewing trends for a unique, heirloom-inspired aesthetic. Conscious of the demands placed on today’s modern woman, Jessica designs each piece to stand out, but also to work effortlessly within a client’s lifestyle and existing wardrobe.

PURPOSE OF POSITION:
This role is a 12-month Maternity Cover. The Senior Digital & Social Media Specialist leads the day-to-day running of Jessica McCormack’s organic social and digital channels, with a remit built around one idea: bringing rigour and method to organic activity, rather than treating it as a publishing function. This is a senior, hands-on role for someone equal parts data-literate and culturally fluent. You will own how we grow and qualify our audience — identifying the right communities, platforms and content territories to recruit the tastemakers who matter to the brand, and measuring what actually moves the needle. You will also be the connective tissue between organic and paid, working closely with our media agency and creative partners to keep activity briefed, boosted and read through a single, consistent lens. Reporting into the Head of Marketing and working alongside the Digital & Social Media Coordinator, you will take senior ownership of business-as-usual activity. This is not a creative role. It is a strategic, analytical one for someone who can put science behind organic, read culture as well as a dashboard, and tell the difference between an audience that is growing and one that is growing well.

RESPONSIBILITIES:

• Organic Strategy & Performance
  • Own a measurement-led approach to organic — defining the KPIs, audience-health signals and benchmarks that tell us whether activity is working, not just whether it went out.
  • Move organic beyond publishing: structured testing of formats, posting logic and content territories, with clear read-outs on what to scale and what to drop.
  • Identify and build the case for new platforms and content verticals that recruit incremental, qualified audience to the brand.
  • Translate performance data into clear direction the wider team can act on.
• Tastemaker & KOL Strategy
  • Build and run a recruitment strategy for tastemakers and KOLs grounded in analysis rather than gut feel.
  • Vet profiles properly — audience composition, authenticity, brand fit and overlap — so we partner with genuine tastemakers, not traditional influencers.
  • Brief, track and measure each partnership as something we can read and learn from, not just a one-off post.
  • Keep a live map of the cultural landscape around the brand: who matters, why, and how that is shifting.
• Community & Audience Recruitment
  • Grow and nurture communities of tastemakers across channels, prioritising quality of audience over volume.
  • Use new platforms, formats and verticals as deliberate recruitment routes to audiences we don’t already hold.
  • Monitor and engage with DMs and community interaction in a considered, brand-aligned way.
• Paid Media Coordination
  • Act as the organic team’s point of contact with the media agency and creative team, keeping activity joined up across the funnel.
  • Support the paid social roll-out and boosting roll-out — asset compilation, copy briefing, and audience and targeting input.
  • Bring real fluency in the media and paid media ecosystem: how targeting, creative testing and optimisation work, and how organic signal feeds paid performance.
  • Help close the loop between paid results and organic strategy.
• Newsletter & CRM Support
  • Support the build and deployment of newsletters in line with the digital calendar (Mailchimp / Klaviyo).
  • Help maintain audience segmentation so email sits coherently alongside social.
• Reporting & Insight
  • Own weekly and monthly reporting across digital channels, with a focus on insight over numbers.
  • Run ad-hoc analysis to inform content, audience and campaign decisions.
  • Keep trackers, reporting templates and documentation organised and reliable.
• Team & Continuity
  • Work closely with the Digital & Social Media Coordinator to keep delivery smooth across all outputs.
  • Communicate clearly and collaboratively across marketing, e-commerce, retail and external partners.

QUALIFICATIONS AND EXPERIENCE
4–6 years in a social or digital role, ideally within luxury or a comparable premium environment. A genuinely data-driven approach to organic — comfortable with analytics and social listening, and turning numbers into decisions. Working knowledge of the media and paid media ecosystem, and of how organic and paid connect. Experience with KOL / tastemaker strategy, including the analysis of profiles and audiences for brand fit. Experience supporting paid social campaigns and coordinating with media and creative partners. Confident with email platforms (Mailchimp / Klaviyo) and reporting tools.

IDEAL CANDIDATE
Culturally astute — a real feel for who and what is shaping taste, and why it matters to a brand like this. Analytical by instinct; happiest when there is a question to answer with data. Highly organised, with sharp attention to detail. Proactive, adaptable and steady — able to run the day-to-day independently. Genuine interest in luxury, jewellery and digital culture.
