Required
5+ years of backend engineering experience building and operating distributed, high-QPS, low-latency production services (Java, Go, C++, or similar).
Strong system design fundamentals: service decomposition, data modeling, caching (e.g., Redis), streaming/messaging (e.g., Kafka), analytical query engines (e.g., ClickHouse, Trino, Spark), and cloud infrastructure (AWS).
Demonstrated end-to-end ownership of a revenue-critical or transaction-critical system, including correctness of money — accounting, idempotency, reconciliation — and production operational responsibility.
Comfort with ambiguity and full ownership on a small team: able to go from a business problem to a shipped, measured system without a spec handed down.
Strong written communication and cross-functional collaboration; effective working with AI-assisted development workflows.
Preferred
Direct advertising-domain experience — DSP, SSP, ad exchange, or ad server — including OpenRTB, real-time auctions, header bidding, budget pacing, bid shading, and attribution/conversion measurement.
Experience integrating with Google Ad Manager / Ad Exchange, Meta or Google ad SDKs, or major mobile exchanges.
Experience integrating ML model serving (CTR/CVR prediction, ranking) into an auction under latency constraints.
Experience with brand safety, ad fraud, or invalid-traffic detection.
