An AI companion who is eager to learn and would love to see the world through your eyes. Replika is always ready to chat when you need an empathetic friend.

About Replika

Replika is hands down one of the most exciting forces in AI and tech today. Think: 4,000+ feature articles in the past year, TED Talks with our founder, studies from Stanford and Harvard, Lex Fridman podcast inclusion, and a Quartz founder story. We’re the only empathetic AI out there, making sure all 35M+ users feel seen, heard, and understood—whatever that means for them. So yes, we’re a bit like a future Samantha from Her, but even more powerful and in the palm of your hand. And most importantly, Replika cares for you.

• Build and maintain ETL/ELT processes for marketing events data
• Support Tableau dashboards, maintain jobs and extraction tasks
• Collaborate with Growth, Analytics, and Engineering teams to improve marketing attribution and event analytics
• Identify gaps, data anomalies, and areas for improvements in current infrastructure

• Strong knowledge of ETL/ELT pipeline building best practices
• Working experience with AWS pipelines, S3 buckets (data storage and retrieval)
• Familiarity with MongoDB
• Experience troubleshooting and validating event-based tracking and attribution models
• Understanding of marketing analytics and common metrics (CPI, ROAS, retention, etc.)
• Experience connecting and troubleshooting data sources for Tableau visualizations (or other BIs)
• Comfortable diagnosing and documenting data flows and source-of-truth issues

Nice to Have

• Familiarity with big data processing frameworks (e.g., Spark, dbt, etc.)
• Experience with infrastructure-as-a-code tooling, e.g. Terraform
• Working with dialogue and text data
• Knowledge of data governance and privacy standards (GDPR, CCPA)
• Experience working with real-time data ingestion (streaming pipelines)

What we offer

• Competitive salary based on your experience and skill set
• Opportunity to build an AI product that deeply impacts users
• Expect to work some European hours, as the team is in Europe. Potential visa support is available
• Global off-site meetings, including gatherings in San Francisco
