Job description

We are hiring a Data Engineer to build the pipelines that track how users move through our app. You will be responsible for turning raw user behavior into clear insights - like where people drop off in the funnel and why they keep coming back.

What You'll Do

• Build and maintain reliable pipelines to track user behavior and app events.
• Analyze user conversion rates and retention through funnel and cohort analysis to identify exactly where we are winning or losing users.
• Set up and manage tools like PostHog, Amplitude, or similar platforms to track real-time data.
• Build the data framework for A/B tests so we can measure the impact of new features or ads.
• Review session recordings to judge user intent and identify friction points in the app experience.

What We're Looking For

• You have worked on consumer apps at scale and understand the nuances of high-volume user data.
• You are proficient in data science and building backend pipelines for event tracking.
• You are an expert in modern analytics suites (PostHog/Amplitude) and visualization software.
• You ensure data is accurate and clean so management can make decisions with confidence.
• You don't just report data; you look for patterns and suggest what we should test next.
• You are comfortable watching session recordings to understand user behavior beyond just the numbers.
• You have worked with ads data before (preferred but not strictly necessary).

General Notes

• Availability: <4 weeks
• Prior startup experience is highly valued.
• Compensation Range: Competitive and market-aligned. The final package depends on skills, experience, and abilities – not your degree.
