- Own end-to-end delivery of features and services, from technical design and implementation through deployment, monitoring, and iteration, ensuring high availability and operational excellence.
- Diagnose and resolve complex production issues, perform root cause analysis, and drive long-term improvements in reliability, observability, and resilience across services and dependencies.
- Collaborate with cross-functional partners, contributing technical expertise to product discovery, backlog prioritization, and data-driven decision making while ensuring solutions are reusable and fungible across multiple domains.
- Safely integrate and operate AI/ML‑enabled solutions that improve outcomes, including familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products.
Minimum Qualifications:
- Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience.
- 5+ years of relevant professional experience.

- Experience building or operating ad servers, ad bidders, ad selection or ranking systems, campaign delivery systems, or other ad tech / programmatic advertising platforms, or similarly complex recommendation or ML-driven decisioning systems at scale.
- Experience designing and operating high-throughput, low-latency distributed services in production, with strong focus on observability, reliability, and performance optimization.
- Hands-on experience with AWS, ideally including serverless patterns and infrastructure-as-code tools such as CloudFormation.
- Experience with modern software delivery practices, including containerized deployments (for example, Docker and Kubernetes), CI/CD pipelines, and test automation.
- Demonstrated ability to collaborate with Data Scientists and apply AI/ML in real-world systems, including integrating models into production services or developing new data-driven features that improve relevance, personalization, or operational outcomes.
