We are looking for a Senior Social Media Manager, with a natural flair for social, who will be responsible for the social media presence of OneDome and all brands within the OneDome Group. We are looking for a growth-minded strategist who understands the nuance of selling into two distinct audiences:

• B2B: Mortgage brokers and investors.
• B2C: First-time buyers, home movers, and consumers looking for a smarter way to buy.

• B2C (Instagram and Facebook): Translate the complex journey of home buying into aspirational, educational, and viral content. Demystify mortgages and showcase the emotional payoff of moving.
• Own the social media KPIs: follower growth, engagement rate, share of voice, and – critically – referral traffic.
• Build and nurture thriving communities across all Group brands.
• Engage directly with mortgage brokers on LinkedIn, fostering relationships that drive B2B pipeline.
• Manage brand reputation by liaising with the PR team to handle queries, sentiment shifts, and crisis communications with agility.
• Manage the organic content calendar across the Group, balancing promotional, educational, and entertainment pillars.
• Collaborate with the PR team to amplify press wins, data stories, and company announcements.
• Work with the SEO team to ensure social content drives traffic to high-priority pages and aligns with keyword strategy.
• Identify, brief, and manage relationships with external content creators and influencers to scale authentic content production.
• Provide weekly and monthly reports linking social activity to traffic and lead generation.
• Use social listening tools to identify trends, sentiment shifts, and opportunities for reactive marketing.
• Continuously A/B test copy, visuals, posting times, and CTAs to maximize ROI.

• Proven experience as a Social Media Manager, ideally within fintech, proptech, or a high-growth startup environment.
• Demonstrable experience managing social for a portfolio of brands or a multi-brand group.
• A track record of growing audiences in a fintech or high-growth business.
• Experience managing creator/influencer partnerships end-to-end (from negotiation to performance analysis).
• Proficiency in analytics platforms and the skill to use it to dictate creative direction.

• Ability to work cross-functionally with PR and digital marketing teams.
• You can pivot a strategy overnight based on performance data or market news.
• You are comfortable with the pace of a fast-growth scale-up.
