Job description

Marketing Assistant: (Data, PM, Email) — Contract

Location: New York City (On-site preferred)
Compensation: $25/hr

About the role

Atoms is looking for a Marketing Assistant who lives at the intersection of creativity and data — someone curious about why people buy, how they behave, and how to turn that insight into growth.

You’ll work directly with the Growth Lead to optimize email, paid, and website performance — building small wins quickly by testing, learning, and improving every day. This role is perfect for someone who’s young, analytical, creative, and wants to grow fast inside a startup.

What You'll Do

Analyze campaign performance and customer data to uncover insights that drive conversion.

Support the Growth Lead in managing email campaigns, testing subject lines, and improving flows.

Coordinate across creative, design, and dev teams to launch experiments efficiently.

Build and maintain reports or dashboards to track KPIs and performance trends.

Test new ideas using AI or automation tools to make campaigns faster and smarter.

Document learnings and share clear next steps with the team.

What we're looking for

A background in data analysis and understanding customer behavior.

Someone who’s experimented with AI tools (ChatGPT, Midjourney, automation apps, etc.) in personal or side projects.

Sharp communication and project management skills — able to move work forward fast.

Interest in marketing, user psychology, and building things that grow.

Hands-on familiarity with tools like Google Analytics, Klaviyo, Shopify, Notion, and Google Sheets.

An independent thinker who loves experimenting, measuring, and improving.

Who should not apply

Anyone not willing to go deep into details or data to get things right.

Those who prefer waiting for direction instead of taking initiative.

People asking for frequent remote work — this role needs in-person collaboration and quick iteration.

Anyone not willing to learn new tools or challenge their own way of working.

Those who just want to complete tasks, not understand why they matter.
