• Contribute to demand-side integrations and optimization work, including SSP onboarding, OpenRTB request / response handling, auction logic, curation flows, and traffic-shaping or path-optimization capabilities
• Partner closely with product managers, designers, and engineers to translate roadmap items into clear technical designs, scoped milestones, and production-ready implementations
• Develop reporting and observability capabilities that improve visibility into bids, impressions, inventory, advertiser outcomes, and platform health
• Write clean, modular, testable code and uphold strong engineering standards through code reviews, documentation, and thoughtful system design
• Help shape architecture and delivery decisions around latency-sensitive systems, event-driven workflows, privacy-aware data handling, and operational reliability
• Support production readiness by contributing to monitoring, troubleshooting, incident response, and ongoing platform improvements

• Experience working with telemetry, analytics, or event streams to power reporting and operational visibility
• Comfort working across the full delivery lifecycle: discovery, technical design, implementation, testing, deployment, and post-launch support
• Strong problem-solving skills, attention to detail, and the judgment to make pragmatic trade-offs in ambiguous environments
• Ability to work independently and autonomously without requiring constant supervision
