A track record of owning martech architecture decisions and defending them. Ability to write technical implementation specs. Strong SQL and Python, with production experience on a cloud warehouse and transformation layer. Direct experience with ad platform APIs: Meta CAPI, Google Enhanced Conversions, TikTok Events API, or equivalents.

Comprehensive health insurance packages with dependent coverage. Competitive salary with ample opportunities for career advancement and development. Enjoy the flexibility of a fully remote work environment. 401(k) plan with a 4% employer match to help you plan for the future. $100 monthly dogfooding stipend to support trying out our products firsthand.
