- Architect and operate resilient cloud infrastructure (AWS, Pulumi, Kubernetes).
- Lead initiatives to improve availability, latency, and performance at scale.
- Design and evolve our CI/CD pipelines to optimize for speed, safety, and repeatability.

- Strong programming ability in Go or Python. We use Go.
- Deep understanding of distributed systems (Kafka, ClickHouse) and microservices architecture.
- Mastery of container orchestration (Kubernetes) and production debugging.
- Strong sense of ownership, and the judgment to balance velocity with reliability.
