Our Team

The Netflix Ads Signal Acquisition: CAPI & Audience Onboarding team plays a critical role in collecting signals for member understanding, measurement and outcome optimization.

The Role

As a Software Engineer on the Ads Signal Acquisition: CAPI & Audience Onboarding team, you will be instrumental in designing and developing Netflix Conversion APIs. These APIs are essential for powering critical Measurement, Optimization, Retargeting and Reporting capabilities.

As a Software Engineer on the Conversions & Audience Onboarding team, you will develop client-side SDKs for capturing consented advertiser signals across their digital properties, build interfaces that allow advertisers to upload offline conversion data, and architect high-volume, low-latency ingestion APIs. You will develop state of the art JavaScript capabilities to capture key user interactions—from Page Views and Product Discovery to down-funnel actions like Add to Cart, Checkout, and Purchase—while rigorously upholding privacy regulations and user consent preferences. Additionally, you will engineer scalable APIs to process these high-throughput conversion signals. You will collaborate with a team of talented professionals who are deeply passionate about ads technology and privacy, fostering a culture that values creativity, diversity, and continuous learning.

- Experience with leading tag management systems such as Google Tag Manager (GTM), Tealium iQ, Adobe Launch, or Segment.

- Strong grasp of JavaScript security threats and mitigation strategies.
