User Acquisition Manager

We’re looking for a Paid Growth Manager to own and scale Opal’s paid growth engine from our Paris office.

Who You Will Work With:

• Manager: Marjolaine (Growth Lead)

• Direct Reports: Elise (Creative Ads Producer)

• Key Cross-Functional Collaborators: Heba and other members of the Product, Finance, Data, Brand & Organic Growth team.

Location: Hybrid in Paris, France (2 days remote per week)

Why This Role and Why Now?

At Opal, we’re building tools to help people reclaim their time and focus on what truly matters.

Over the last year, we’ve built a much stronger performance foundation: a robust data stack, clear creative processes, and tight collaboration between product, data, and marketing. Heba has been leading UA hands-on while helping design and refine this setup.

Your mission: own and grow Opal’s paid acquisition across key channels, lead our creative testing roadmap with Elise (creative ads producer), and turn our data and creative engine into sustainable, profitable growth.

This is a great fit if you’re:

• ~2–3 years into your performance career and ready for more ownership

• Excited to think full-funnel and impact what users do and retain in the product
