Company Description

EQUALS is a well-funded London-based music social network with 1 million monthly active users, backed by the investors behind Spotify, A24, and Facebook. Founded by a world-class team from Apple, Nike, and Instagram, EQUALS has sparked over 40 million friendships by uniting the world through the universal language of music.

Job Description

EQUALS is seeking a technical builder to own their systematic marketing engine. You will treat paid acquisition like a quant desk, applying advanced mathematics and frontier AI to optimize a live portfolio across major social platforms. This hybrid role blends cultural intuition with rigorous experimentation to drive global user growth through music.

Location

London, UK

Why this role is remarkable

• Join a high-traction social network with 1 million MAU that is outperforming platforms like Instagram and Snapchat in engagement and usage.
• Work alongside an elite team of creatives and technologists from Apple, Nike, and Instagram, supported by legendary investors who funded Spotify and Facebook.
• Build a first-of-its-kind marketing engine from the ground up, treating cultural trends as mathematical optimization problems using the latest AI models.

What You Will Do

• Manage and optimize a multi-platform paid spend portfolio across TikTok, Meta, and Snap using real-time rebalancing systems instead of manual spreadsheets.
• Deploy generative AI and autonomous agents to iterate on creative content and marketing tooling at a pace no traditional team can match.
• Design scientific measurement frameworks for incrementality, attribution, and causal inference to replace gut-feel reporting with rigorous, actionable experimentation.

The ideal candidate

• Strong quantitative background in mathematics, statistics, or machine learning, with a passion for applying these disciplines to messy, real-world consumer data.
• Fearless early adopter of AI who can bridge the gap between creative hooks and technical model reasoning to unlock new growth capabilities.
• Pragmatic builder with a bias for action, capable of shipping, measuring, and iterating quickly within a fast-paced, high-stakes startup environment.
