Design Data Pipelines: Architect systems to process and analyze vast volumes of impression, click, and conversion data for reporting, forecasting, and real-time optimization.

5+ years of experience in software engineering, with a proven track record of building and shipping large-scale, distributed systems.
Must-Have Technical Skills: Languages: Deep proficiency in Go (Golang) and/or Java/Kotlin.

Databases: Strong experience with SQL (e.G., PostgreSQL, MySQL) and NoSQL databases (e.G., Redis for caching, Cassandra/ScyllaDB or DynamoDB for time-series data).
Data Technologies: Experience with stream-processing technologies like Kafka, Flink, or Spark Streaming.
Architecture: Solid understanding of microservices architecture, API design (REST, gRPC), and containerization (Docker, Kubernetes).
Domain Knowledge: Direct experience in the ad-tech industry is crucial.
You must understand the RTB ecosystem, including protocols like OpenRTB (2.5/3.0), ad serving concepts (VAST/VPAID/VMAP), and attribution models (SKAdNetwork, MMPs).
Problem-Solving: Excellent analytical and problem-solving skills with a passion for optimizing complex systems for latency and scale.
Preferred Qualifications Experience in building or working extensively with a DSP, SSP, Ad Exchange, or Ad Network.
Hands-on experience in developing mobile SDKs for Android (Java/Kotlin) and/or iOS (Objective-C/Swift), including concerns like package size, memory usage, and compatibility.
Experience with cloud platforms (AWS, GCP, or Azure) and infrastructure-as-code (Terraform, CloudFormation).
