• Champion improvements to developer experience, integrations, and testing processes

• Leverage vended and open-source cloud technologies to reduce maintenance costs and improve efficiencies, ensuring our products remain profitable

• Collaborate with other engineers to develop and enhance core capabilities, infrastructure, and architecture

Here is the approach we value:

• Author, review, and optimize production-quality code that adheres to industry standards and best practices (IaC, CICD, etc.)

• Demonstrate a passion for software engineering, with a strong sense of responsibility for the code you and your team write

• Take ownership of issues and be a strong advocate for your team and the products

• Embrace failure as a learning opportunity—use research and experimentation to ultimately choose the best solutions that meet company goals

• Follow a progressive development methodology, moving from proof-of-concept to prototype to production release

• Enhance the effectiveness of your squad, the team, and our partners by sharing your knowledge, communicating about complex technologies and problems in simple terms, and driving technical decisions

• Collaborate across functions, squads, teams, and organizations to best serve our users

Qualifications & Experience...

• 8+ years progressively complex experience designing, building, and shipping products

• 5+ years backend engineering experience with data-heavy applications

• 3+ years of experience with IaC, deployment pipelines, and relational databases

Additional Information

On December 5, Netflix and Warner Bros. Discovery announced they have entered into a definitive agreement under which Netflix will acquire Warner Bros., including its film and television studios, HBO Max and HBO. The transaction is expected to close after the separation of Warner Bros. Discovery's Global Networks division, Discovery Global, into a new publicly-traded company, which is expected to be completed in Q3 2026.
