Content & Growth Lead in London

Affinity Labs builds, launches and scales software products with the world's leading content creators. We pair their audience and domain expertise with our product, engineering and AI-native workflow to launch apps people love, then grow them fast. We ship products faster and leaner than traditional teams, and every one goes to market with a creator audience of millions behind it. Great software plus built-in distribution is how we build category-defining consumer apps.

Work on products distributed to millions at launch through partnerships with some of the world's biggest creators, move at the pace of an early-stage AI startup, and compound your impact across multiple products rather than just one.

Role Description

You’ll own content and growth across a portfolio of consumer apps, working closely with the founders, creators and the wider team to turn a creator's audience into a product's users. This is an early-stage, hands-on role with real autonomy. One week you’re shaping the launch content for a new app with a household-name creator, the next you’re running paid experiments and tuning the organic channels on a live product that’s growing fast. You’ll move between products quickly, carrying what you learn with you, and you’ll always be testing: which ideas, formats and hooks actually convert an audience, and how to scale the ones that do.

Responsibilities

• Run a constant cycle of creative experiments with your creators, testing concepts, formats and hooks to uncover what genuinely moves an audience to download and subscribe.
• Own the organic social presence of our products and of Affinity Labs itself: planning, posting and growing the pages week to week.
• Diagnose the full conversion path, from the first three seconds of a video to the call to action to the App Store page, and fix what's leaking.
• Take your strongest creative into paid social, shaping ad creative and helping run the campaigns that extend a creator's reach.
• Support UGC campaigns end to end, from sourcing and briefing creators through to getting content live.
• Own the content and growth story for your products: track the metrics that matter, surface what's working, and let the numbers guide what you make next.
• Work side by side with world-class creator partners on content and launch.

Essential Requirements

• 3 to 6 years in social-first content and growth, ideally with consumer or app products, with work you can point to that moved a real number.
• Deep understanding of short-form video: what makes someone stop scrolling, what makes them act, and how that differs across platforms.
• A conversion mindset. You judge content by what it drives, not by vanity metrics, and you can explain why a piece did or didn’t work.
• A hands-on operator. You’re happy running the pages, briefing editors and shipping every week, not just writing strategy decks.
• You work through influence. You can earn the trust of creators and their teams and bring them with you.
• Startup mindset: high ownership, comfortable with pace and ambiguity, and hungry to grow fast in an early-stage environment.

Desired

• Hands-on experience running paid social (Meta, TikTok), with a feel for media buying and not just creative.
• Direct experience working with creators, influencers or talent in a content or marketing context.
• Experience with App Store conversion or mobile growth specifically.
• Comfort using AI creative tools (Higgsfield, Nano Banana or similar) to produce and iterate on content quickly.
• Familiarity with consumer analytics and monetisation stacks (PostHog, RevenueCat or similar).

Why this role is a career launchpad

• Build alongside the world's biggest creators. You’ll work directly with household-name partners on content going to audiences of millions, exposure that’s nearly impossible to find anywhere else.
• Own content and growth from day one. You step in as the person who defines how creator-led software gets sold, with genuine ownership over the work and the results.
• Ride a rocket. The roadmap is ambitious, the products are growing fast, and the bar is high.
• Grow like crazy. You’ll touch multiple products each year across launch and scale. The reps you’ll get in 12 months here would take years in a typical marketing role.
• Learn from builders, not bosses. Work shoulder to shoulder with founders who've scaled startups, closed multi-million-pound rounds and collaborated with over 1,000 creators.
