We are a dream team obsessed with the uncomfortable excitement of discovering what happens when you merge creativity, intuition and cutting-edge technology. Come be a part of what’s next.

We launched a new ad-supported tier in November 2022 to offer our members more choice in how they consume their content. Our new tier allows us to attract new members at a lower price point while also creating a compelling path for advertisers to reach deeply engaged audiences.

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 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.

• Ability to design and architect scalable, high-performance systems.
• Proven track record in developing, deploying, and maintaining advertising pixels, SDKs, or tag management systems.
• Familiarity with Consent Management Platforms (e.g., OneTrust, TrustArc) and their APIs.
• Experience with leading tag management systems such as Google Tag Manager (GTM), Tealium iQ, Adobe Launch, or Segment.
• Deep understanding of browser environments (Chrome, Edge, Safari, Firefox), browser APIs, and common limitations for client-side scripts.
• Strong grasp of JavaScript security threats and mitigation strategies.
• Experience with database systems, both SQL and NoSQL (e.g., MySQL, Cassandra, MongoDB).
• Understanding of big data technologies such as Hadoop, Spark & experience working with streaming technologies like Kafka & Flink
• Understanding of distributed systems and cloud computing platforms like AWS, GCP, or Azure.
• Understanding of data privacy and security best practices.
• Ability to troubleshoot complex systems and resolve issues efficiently.
• Excellent communication skills, both verbal and written.
• Ability to work collaboratively in a cross-functional team environment.
• Experience in leading technical discussions and driving decisions.
• Ability to think creatively and propose innovative solutions.

Nice to haves

• Familiarity with clean rooms and industry-leading privacy-enhancing technology for multi-party data sharing.
• Experience working in the CTV space and knowledge of its unique constraints.
