Software Engineer L4 - Experimentation Platform

Netflix is one of the world's leading entertainment services, with over 300 million paid memberships in over 190 countries enjoying TV series, films and games across a wide variety of genres and languages. Members can play, pause and resume watching as much as they want, anytime, anywhere, and can change their plans at any time.

The Experimentation Platform (XP) team builds the foundation that powers the entire experimentation lifecycle at Netflix. Our tools are at the heart of how Netflix learns, innovates, and delivers personalized experiences to members worldwide. We partner with engineering, product, and data science teams across Streaming, Games, Ads, and more to enable rigorous A/B testing and accelerate decision-making.

We are seeking a Full-Stack Software Engineer (L4) to help evolve our flagship experimentation UI product (ABlaze) and the underlying platform services that power experimentation at scale. This role is a chance to shape how thousands of Netflix employees design, run, and interpret experiments - ultimately influencing product experiences for hundreds of millions of members.

What You’ll Do

• Build and enhance end-to-end experimentation features in ABlaze, Netflix’s primary experimentation UI, and related internal tools.

• Contribute across the stack: from intuitive, performant UIs to reliable backend APIs and data integrations.

• Collaborate closely with designers, product managers, and data scientists to deliver features that reduce friction and make experimentation easier and more impactful.

• Develop scalable, secure, and reliable systems that can support the high volume and complexity of experiments run across Netflix.

• Leverage metrics, logging, and observability to make data-informed product and engineering decisions.

Required Skills & Experience

• Strong foundation in full stack development, with hands-on experience building and maintaining production systems.

• Proficiency with modern frontend frameworks (React preferred) and the ability to deliver polished, user-friendly experiences.

• Experience building and consuming backend APIs (e.g., gRPC, GraphQL, REST) and working with distributed systems.

• Experience with making data-driven decisions; comfortable using metrics and experimentation to guide product improvements.

• Ability to collaborate effectively with cross-functional partners (engineering, design, product, and data science).

• Strong communication skills, both written and verbal, with the ability to explain complex technical decisions to non-technical stakeholders.

Nice to Have Skills/Experience

• BS/MS in Computer Science, Data Science, or a related field (or equivalent industry experience).

• Experience building internal platforms or developer tools that support large engineering or data science communities.

• Exposure to experimentation, analytics, or measurement systems at scale.

• Familiarity with cloud-based environments (e.g., AWS, GCP, or Azure).

• Passion for improving developer experience and usability of internal tools.
