- 5+ years of software engineering experience, with demonstrated ownership of production services in a service-oriented architecture
- Proven track record designing, scaling, and maintaining distributed systems handling high-throughput, low-latency workloads
- Hands-on experience with at least two of the following: Golang, Kafka, Redis, MongoDB, or similar infrastructure technologies
