Design, build, and operate high-performance gateway and routing components in Go.
Own technical direction for your area, including authoring design documents, leading architectural reviews, evaluating trade-offs, and driving decisions.
Build and evolve infrastructure for authentication, caching, rate limiting, request queuing, and traffic shaping.
Collaborate with SRE, Infrastructure, and Platform teams to meet availability, scalability, and observability requirements.
Stay current with relevant technologies, protocols, and industry patterns, presenting findings and proposals.
Deliver features end-to-end, from design through production rollout and ongoing maintenance.

Familiarity with AI/LLM serving infrastructure.
Experience with Docker, container orchestration, and cloud infrastructure (AWS, Azure, or GCP).
Experience with Redis-based caching and pub/sub patterns.
Exposure to API gateway or service mesh internals (e.g., Envoy, Kong, custom proxies).
Integration with third-party REST/gRPC APIs at scale.
Contributions to open-source projects.
Comfortable working in a globally distributed team across multiple timezones.
