Teams at Nexxen

Develop and maintain low-latency, high-reliability backend systems for a programmatic SSP using Node.js. Build and optimize server-side logic to handle billions of requests daily, deploy and monitor in a Linux environment, use Redis/Aerospike/KeyDB and MySQL/Vertica, integrate Kafka and observability tools, follow Agile processes, use Git and CI/CD, and participate in rotating on-call support.

Design, implement, and operate high-throughput, low-latency SSP services. Integrate with DSPs and data providers, apply AI-first approaches, resolve performance bottlenecks, drive observability/automation, participate in on-call SRE duties, and mentor other engineers.

Design and optimize a low-latency real-time bidder and throttling layer, build the traffic-aggregation job, analyze billions of events with SQL, and apply interpretable gradient-boosted models to decide which requests to forward. Collaborate across the stack from production Node.js services to data pipelines and ML-driven rules.
