Location: San Francisco
Reports to: Head of Growth
Jinba is the enterprise workflow automation platform that lets teams describe workflows in natural language and deploy them as
APIs or MCP servers. We have 40,000+ daily enterprise users at Japanese Fortune Global 500 companies — and we're just getting
started.
We're part of Y Combinator W26.
We're hiring a Growth Engineer to own the systems that turn signups into customers. You'll work across the full stack — building
landing pages, instrumenting funnels, running in-app experiments — whatever it takes to move the metrics.
This is an engineering role with a growth mindset, not a marketing role with some coding involved. You'll ship real features, run
real experiments, and have direct impact on revenue.
