Marketing Data Scientist - Internship
Build the growth engine behind the next big FemTech company. 🚀💜
LYNA is building an AI-powered women’s health platform connecting nutrition, hormones, symptoms, and personalised health insights. We’re looking for a Growth & Marketing Data Science Intern who sits at the intersection of data, paid advertising, automation, and growth.
This is for someone who doesn't just want to analyse data — you want to use data to make ads smarter, automate growth, and find what actually drives users to LYNA.
What you'll do
- Analyse paid advertising performance across Meta and other channels
- Identify patterns in CAC, CTR, CPC, CVR, ROAS and retention
- Build dashboards and reporting to understand growth
- Help automate repetitive marketing and growth workflows
- Develop systems for campaign tracking, attribution and experimentation
- Analyse audiences and identify opportunities for better targeting
- Work with creative teams to determine which hooks, messaging and creatives perform best
- Run A/B tests across ads, landing pages and funnels
- Use data to recommend where we should increase, decrease or reallocate ad spend
- Build simple automations using tools such as Make, Zapier, n8n, APIs or Python
- Help turn raw marketing data into actionable growth decisions
- Work directly with the founders to build LYNA's growth infrastructure from the ground up
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Your first mission
Help us build a data-driven paid growth machine. You'll work across: Ads → Data → Automation → Insights → Experiments → Scale

Get help with your application
Your very own career expert that helps elevate your application to the next level.

What you'll gain
- Real experience managing and analysing live growth campaigns
- Hands-on exposure to AI + data + paid advertising + automation
- Direct collaboration with LYNA's founders
- The opportunity to build systems from scratch rather than maintain legacy infrastructure
