Netflix is seeking a distributed systems engineer to join the Ad Server Platform team, responsible for building and maintaining the ad serving infrastructure. The role involves ensuring reliable ad delivery across platforms while collaborating with various teams to enhance the ad tech ecosystem.

• 7+ years building distributed systems and backend services at scale
• Built or operated ad servers, SSPs, DSPs, or real-time bidding infrastructure
• Strong platform engineering mindset: APIs, contracts, backward compatibility, multi-team consumers
• Deep understanding of latency engineering: profiling, cache hierarchies, connection pooling, async I/O
• Experience designing highly available, fault-tolerant systems with strong understanding of concurrency, parallel processing, and microservices architecture
• Experience with event-driven architectures: Kafka, Flink, or similar stream processing
• Proficiency in Java, Kotlin, or similar JVM languages with a history of writing production-quality, well-tested code
• Understanding of ad serving concepts: targeting, frequency capping, publisher controls, programmatic protocols
• Ability to operate in an environment that is a mix of big-tech scale and startup speed

• Build and operate the ad serving runtime: request orchestration, targeting evaluation, policy enforcement, and ad selection under strict latency SLAs
• Work closely with the programmatic team on infrastructure related to bid request/response handling, QPS management, and load shedding
• Build and evolve the rule engine framework: a unified execution framework for blocking policies, frequency caps, supply floors, ad podding rules, competitive separation, and ad load management
• Maintain and enhance APIs consuming upstream business objects, transforming them, and propagating updates to the ad server
• Improve and evolve the frequency management service
• Design logs, APIs and data contracts consumed by downstream teams
• Drive platform reliability: SLO-driven development, graceful degradation, circuit breakers, capacity planning, and incident response
• Instrument comprehensive logging, tracing, and telemetry across the ad request lifecycle
• Own the full software development lifecycle for your systems: design, implementation, deployment, operations, and deprecation

• Employees at Netflix are often offered flexible, people-first benefits—unlimited time away, generous parental leave, global family-forming support, mental-health programs (mindfulness, free counseling/coaching), and health coverage tailored by country. Financially, Netflix pays at personal top-of-market and lets employees choose their mix of cash vs. fully-vested 10-year stock options, alongside donation and volunteer matching. Convenience perks can include trust-based travel/expense policies, relocation support, and “Work, Not Drive” rideshare flexibility.
