Marketing Engineer

=About EQUALS

EQUALS is the music social network. We have 1 million monthly active users, people use us more than Instagram, Snapchat, and X, and we have sparked over 40 million friendships. We are a team of creatives and technologists from giants like Nike, Instagram, and Apple, backed by the investors behind Spotify, A24, and Facebook, making us one of the most well funded consumer social businesses in the game. Our mission is to unite the world through its most universal language: music.

=Your Role

We have built a world-class systematic approach to marketing, and paid acquisition runs like a quant desk. As a Marketing Engineer at EQUALS, you will own that engine and push it to the frontier. This is a rare hybrid role: part scientist, part growth operator, part creative. You will treat marketing as an optimisation problem worthy of real mathematics, deploy AI as a first-class tool, and turn taste and culture into an edge no competitor can copy. You will invent capabilities the team has never had, and be the frontier adopter who brings the latest in AI and applied maths into everything we do.

=Your Realm

Portfolio Optimisation

• Treat our paid spend as a live portfolio to be optimised, allocating budget across TikTok, Meta, Snap, AppLovin, and Apple Search Ads for maximum return.

• Build systems that rebalance in near real time as signal changes, not spreadsheets that update once a week.

Applied AI at the Frontier

• Be the frontier adopter of AI on the marketing team, inventing capabilities we have never had before.

• Use generative models to create, test, and iterate creative and copy at a pace no manual team can match.

• Build agents and tooling that make one marketer as productive as ten, and keep us ahead of every model release.

Measurement & Evaluation Science

• Build the scientific frameworks that tell us what is truly working, from incrementality and attribution to creative testing.

• Define the metrics that matter (install rate, CPI, retention, LTV) and make them trustworthy, causal, and fast to read.

• Replace gut-feel reporting with rigorous experimentation the whole team can act on.

Growth Meets Culture

• Turn cultural instinct into measurable advantage, blending taste for music and internet culture with hard data.

• Find the creative angles and audiences that move people, then scale them systematically.

• Know when to trust the model and when to trust the gut, and design systems that respect both.

=Who You Are

• Both creative and technical, equally comfortable talking hooks and cultural angles as reasoning about optimisation and models.

• Strong on the technical and quantitative side first, a scientist or builder at heart who happens to love growth and culture.

• Excited by real mathematics, applying optimisation, statistics, and machine learning to messy real-world problems.

• An early and fearless adopter of AI, always looking for the capability it unlocks next.

• A pragmatist who ships, measures, and iterates rather than theorising.

• Deeply curious about consumer social and what makes culture and music spread.

• A clear communicator who can influence marketers and engineers alike.
