Senior Backend Engineer (Remote, USA)

(Remote — Americas or Europe)

At Nango (YC W23), we’re building the modern way for developers to build product integrations. Companies run on an ever-growing stack of software, and meaningful automations require these tools to work seamlessly together. That only happens through integrations.

We’re the leading open-source platform for product integrations. More than 100 paying customers — including Linux, Contentful, Semgrep — already rely on Nango. We’ve passed $1M ARR with just 6 people, growing fast through inbound, product-led adoption.

We’re backed by YC and executives from Cloudflare, Retool, Notion. Adoption is especially strong among fast-growing AI companies (e.g. Exa, Vapi, Tennr, Motion), where integrations are the first step to connecting AI agents with the real world.
