Join to apply for the Social Media & Content Manager role at ThirtyThree

Overview

We’re looking for a talented Social Media & Content Manager who’s equally comfortable managing client relationships as they are creating engaging, visually striking content. This is a hybrid role combining social media account management with hands-on content creation, giving you the chance to flex both your project management skills and your creative expertise. You’ll work alongside our Social Media Director, Strategists, Content Creators, and Social Media Managers, delivering consistently high-quality social content. You’ll work across a set of clients such as National Trust, Inverto and the British Army.

What you’ll do

• Be the go-to person overseeing the day-to-day social delivery for your set of client accounts.
• Manage and coordinate social activity across your clients.
• Ideate, produce, and edit static and video content using Adobe Creative Suite.
• Build and maintain content calendars, reports, and paid campaigns — delivered on time and to best-practice standards.
• Create quality content that is consistent with brand guidelines.
• Lead content planning and production, including social-first shoot planning and delivery, and post-production.
• Schedule, publish, and monitor social activity across channels.
• Build trusted relationships with clients and internal colleagues.
• Lead client calls — presenting work, reports, and updates with confidence.
• Partner with Social Strategists to implement campaigns, paid activity, and always-on social strategies.
• Ensure content is audience-led, insight-driven, and aligned with platform best practice.
• Stay on top of emerging trends, algorithm changes, and competitor activity — turning insights into new ideas for clients.
• Provide consultancy and guidance to help clients navigate the evolving social landscape.
• Support new business pitches and creative proposals.

About you

To thrive in this role, you’ll need at least 3 years’ experience in a social media role (agency experience a plus).

• A motivated self-starter with strong organisation skills and attention to detail.
• Experience applying brand guidelines to create content that is on-brand and optimised for social.
• Experience managing and growing social channels for multiple clients.
• Content creation skills with proficiency in Adobe Creative Suite (Photoshop, Illustrator, Premiere Pro/After Effects).
• Confident in building strong client relationships and presenting work.
• Collaborative and team-oriented, but able to take ownership and work independently.
• Familiar with Paid Social strategy and implementation.
• Experience handling cost proposals and budgets (desirable).

What we offer

• Competitive salary
• Hybrid working model (2 days a week in our London / Bristol studio)
• 25 days’ holiday (pro-rata for fixed term), plus bank holidays and bonus festive leave
