Role overview This Software Engineer position sits on the Engineering Platform team in New York, NY (HQ). Rather than building customer-facing features, this team creates and maintains the core infrastructure that supports over 300 engineers at Ramp.

Establish standardized service pathways, including API design, database migrations, Kafka, Temporal, and secret management, to help teams build infrastructure efficiently and avoid redundant work. Oversee the full suite of developer tools (including Devportal, Graphite, Buildkite, Inspect, deployment processes, LaunchDarkly, and Datadog), with a strong understanding of their interactions, especially under pressure.
