About the Role

We’re looking for a dynamic Social Media & Community Lead, a hybrid role that sits at the intersection of influencer marketing, community building, and content creation.

You’ll balance creativity with commercial awareness — blending storytelling and performance to build brand love, loyalty, and growth.

 

You’ll Own

INFLUENCER MARKETING

  • Build and execute a best-in-class influencer marketing strategy across TikTok, Instagram, and other relevant platforms.
  • Develop a tiered influencer approach, from top creators to micro and nano communities, with clear use-cases and KPIs across storytelling, awareness, and conversion.
  • Manage the Underdays affiliate programme, including Shopify Affiliates, driving consistent revenue growth and tracking performance monthly.
  • Lead creator partnerships and negotiations, managing contracts, deliverables, and vendor relationships.
  • Track, analyse, and report on campaign performance, turning insights into actionable recommendations.
  • Stay ahead of social and cultural trends, identifying emerging voices, communities, and formats before they peak.
  • Collaborate cross-functionally with Marketing, Creative, and Performance to integrate influencers into broader brand campaigns.


COMMUNITY

  • Act as the voice of Underdays across all social platforms, replying to mentions, comments, and DMs with warmth, wit, and consistency.

  • Define and codify our community voice and guidelines, what we say, what we don’t, and how we show up in every interaction.

  • Identify and nurture brand advocates and superfans, transforming organic enthusiasm into meaningful advocacy.

  • Support the development of community-driven activations (Q&As, giveaways, content collaborations, and digital experiences).

  • Confidently host or support events, roundtables, and community gatherings, acting as the in-person brand lead.

  • Manage guest lists, logistics, gifting, and post-event follow-ups for influencer and community events.

     

CONTENT

  • Partner with the creative team to commission and brief creators on brand and ad content, ensuring output aligns with Underdays’ aesthetic and voice.

  • Collaborate with the performance marketing team to source and commission UGC-style ad content for TikTok and Meta, leveraging best practices and whitelisting opportunities.

  • Ideate trend-led, reactive content that taps into cultural moments while staying true to our editorial, intentional brand tone.

  • Capture behind-the-scenes moments from shoots and events, and confidently feature in, or voice, UGC-style videos when needed.

  • Maintain a close feedback loop between content performance, community sentiment, and future creative direction.

 

SOCIAL

  • Own and grow the Underdays TikTok channel, developing an organic content and growth strategy that combines best-in-class storytelling, creator collaborations, and platform insight.

  • Experiment with new content formats and growth mechanics to build visibility, engagement, and emotional connection.

  • Collaborate closely with the brand and creative teams to ensure a cohesive aesthetic and tone across all channels.

     

You Bring

  • 2-3+ years’ experience in social media, influencer, or affiliate marketing, ideally within a DTC, fashion, or beauty brand.

  • A deep understanding of TikTok and Instagram, platform mechanics, trends, and creator ecosystems.

  • An understanding of performance marketing and how influencers/ UGC fit into a growth strategy

  • Proven experience building and managing creator/influencer partnerships that drive measurable results.

  • A strong creative eye and editorial sensibility, aligned with Underdays’ brand: elevated, confident, and intentional.

  • Excellent communication and relationship-building skills,  equally comfortable negotiating with creators and engaging with customers.

  • Confident creating and editing content using tools like CapCut, Canva, or similar.

  • Highly organised, proactive, and adaptable, able to manage multiple projects and priorities in a fast-growing environment.

  • A genuine passion for wellness, community, and building brands that empower women.

     

Why You’ll Love Working With Us

  • Opportunity to shape the voice and presence of a growing modern wellness brand.

  • Creative autonomy and collaboration with a small, driven, female-founded team.

  • Access to brand experiences, and product perks.
