Senior Software Engineer

CNN is seeking a Sr. Software Engineer to serve as a technical authority for CNN's Multiplatform SDK ecosystem - the shared foundation powering application capabilities across CNN's digital products. You will define and execute the architecture for reusable SDKs and telemetry systems that enable consistent, reliable, and scalable data collection across web, mobile, and connected TV platforms.

Your work will power audience analytics, personalization, advertising, and business intelligence for millions of users daily across CNN.com, the CNN mobile app, and connected TV experiences. You will design and maintain highly performing SDKs that standardize event collection, abstract platform complexity, and ensure high-quality data flows into CNN's broader data platform. You will drive architecture decisions, establish engineering standards, and mentor engineers across the organization. If you thrive on building highly reusable systems, solving cross-platform engineering challenges, and creating reliable telemetry infrastructure at scale - this is the role.

Your Role Accountabilities

• Lead the architecture, design, and development of CNN's multiplatform data collection SDKs across web, mobile, and connected TV platforms
• Build and maintain reusable client-side libraries that standardize analytics instrumentation, event delivery, session management, and platform integrations across applications
• Collaborate with Data Engineering, Analytics, Product, and Advertising teams to implement reliable and scalable telemetry solutions that support business and product initiatives
• Contribute to the evolution of event schemas, instrumentation standards, and SDK capabilities to improve data quality and consistency across platforms
• Participate in technical design discussions and contribute to architectural decisions for client-side telemetry and platform integrations
• Mentor junior engineers through code reviews, pairing, and technical guidance while contributing to a strong engineering culture
• Drive best practices around code quality, testing, documentation, observability, and maintainability
• Support CI/CD workflows, release management, and versioning strategies for shared multiplatform libraries
• Troubleshoot and resolve complex production issues related to SDK integrations, telemetry pipelines, and client application behavior
• Communicate technical concepts, implementation details, and tradeoffs clearly with engineers, product managers, and stakeholders across the organization

Required

• 5+ years of software engineering experience with deep expertise in SDK development, telemetry systems, analytics instrumentation, or large-scale client application architecture
• 3+ years of experience building shared libraries, frameworks, or developer platforms used across multiple applications or teams
• S trong expertise in at least one modern client ecosystem such as TypeScript/JavaScript, Kotlin, Swift, or React Native
• Experience designing stable, scalable APIs and reusable software abstractions for internal or external SDK consumers
• Strong understanding of event-driven architectures, client-side telemetry pipelines, batching, retries, offline persistence, and reliable event delivery patterns
• Experience integrating with analytics systems, identity services, consent/privacy frameworks, feature flags, or advertising technologies
• Experience with CI/CD pipelines, automated testing strategies, release workflows, and observability tooling

Preferred

• Experience building analytics or telemetry SDKs across web, iOS, Android, and/or connected TV platforms
• Experience with streaming and event-driven architectures such as Kafka, Kinesis, or similar event ingestion system
• Deep familiarity with analytics event modeling, schema governance, and data quality validation
• Experience with privacy, consent management, GDPR/CCPA compliance, or advertising telemetry standards
• Experience with monorepos, package management systems, and multiplatform build tooling
• Experience supporting high-scale consumer applications in media, streaming, digital advertising, or subscription platforms
• Familiarity with observability tooling, client-side monitoring, and SDK performance optimization
