In this role, you will be responsible for designing, developing, and maintaining the backend infrastructure that powers our large-scale advertising models, with a focus on the performance, reliability, and scalability of inference systems.

• Extensive hands-on experience designing, deploying, and maintaining distributed systems at scale, including managing cloud infrastructure on GCP and orchestrating workloads with Kubernetes.

• Expertise in Golang for building high-performance, low-latency systems and infrastructure.

• Deep experience with monitoring and observability tools (e.g., Prometheus, Grafana).

• Familiarity with microservice architectures, containerization (Docker), and CI/CD best practices.

• Excellent communication and collaboration skills, with an ability to articulate technical concepts to both technical and non-technical audiences.
