We are looking for a Marketing Science Partnerships & Insights Lead to spearhead the strategic direction for our measurement ecosystem—driving our value proposition to clients and partners by testing, learning, and improving the power and performance of Reddit as a media platform.

• Exceptional written and oral communication skills; ability to articulate complex measurement issues to stakeholders and drive alignment.
• Experience at a social media platform is a plus.
