Your New Role...

With deep domain expertise, advanced technical capabilities, and a proven track record of successful collaborations, the AI Enablement C Machine Learning team at CNN is accelerating our digital transformation through strategic applications of machine learning and AI technologies. Our current products include popular, related and personalized content recommendations, contextual ad targeting, and site search-serving millions of CNN users via CNN web and mobile apps. Within the next quarter, we will be launching summarization and classification features with chat to follow early next year.

We have a variety of specializations and collaborate closely, enhancing our platform and adding to the suite of machine learning features running on it.

• Machine learning engineers (MLEs) build models and features
• Data engineers fulfill the availability and latency requirements provided by MLEs
• Some software engineers partner with MLEs to operationalize and expose models and features
• Other software engineers focus on our ML platform and tooling, including A/B testing

Here are some of the key challenges the team will tackle in the next couple of quarters:

• Content Summaries: Support testing and adoption of various types of content summaries from multiple domains, which can be leveraged in consumer experiences along with embedding generation and classification
• Two-Tower Experimentation: Explore options for incorporating additional user context in our personalized recommendations model such as geolocation, time of day and time of year
• All Access Search: Partner with teams across CNN to design and build a roadmap for CNN streaming content search
• Bandit Foundation: Enhance data access and begin experimenting with bandits for online ranking of recommendations
• Optimize Site Performance: Dynamically deliver personalized content alongside cached assets, improving load times and enhancing user experience with features like page-level deduplication

Your Role Accountabilities

• As a Software Engineer II, you will have many opportunities to collaborate with other engineers across the team
• Promote an inclusive and supportive engineering culture on the team
• Solve business problems with simple and straightforward solutions
• Strive for operational excellence--building highly available, low latency, and efficient software with support from other engineers
• Build subject matter expertise related to multiple production systems
• Communicate effectively—through progress updates, timely requests for support, demos, and technical documentation
• Author, test, review, and optimize production-quality code, following best practices for IaC, version control, and continuous delivery with support from other engineers
• Be passionate about software engineering with a strong sense of responsibility for the code you and your team write, delivering high-quality results that improve with each iteration
• Embrace failure as a learning opportunity—use research and experimentation to choose the best solutions that meet business goals, moving autonomously from proof-of-concept to production release

Qualifications & Experience

• Related professional or industry experience
• Bachelor's degree in computer science or a related technical field
• Proficiency in Python and one or more of: Golang, Java, C++, or similar object- oriented languages
