- Scale systems to serve millions of API calls reliably and cost-effectively across cloud and Linux environments.
- Take projects from a fuzzy idea to live in production, moving fast without breaking what matters.
- Work shoulder-to-shoulder with the founders on the architectural and roadmap calls that shape where the company goes.
- Jump in wherever needed across the stack — docs, internal tools, demos, and experiments that push our APIs to their limits.
