- Design, configure and maintain flexible proxy service deployments that accommodate diverse and evolving forwarding patterns, including complex routing rules, protocol handling, and access control requirements.
- Partner with business stakeholders to understand traffic forwarding requirements and translate them into practical, deployable proxy service solutions using a combination of cloud products and in-house platforms.
- Rapidly prototype and iterate on traffic solutions to validate approaches and accelerate delivery, prioritizing deployment efficiency and time-to-value over large-scale infrastructure design.
- Build and maintain observability pipelines covering log collection, metrics aggregation, and usage analysis to provide business stakeholders with actionable insights into traffic behavior.
- Serve as the first point of contact for online incidents and business inquiries related to traffic services; triage issues, coordinate resolution, and communicate status clearly to stakeholders.
- Document solution patterns and reusable configurations to build a knowledge base that accelerates future delivery and onboarding.
