Job description

(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.

What You'll Do

• Design and scale backend systems, APIs, and services for our open-source platform.
• Build world-class developer interfaces: APIs, SDKs, UIs, and a runtime that delights developers.
• Collaborate directly with customers to solve integration challenges.
• Optimize performance, scalability, and reliability across backend services.
• Shape the roadmap and company strategy with high ownership of key decisions.
• Engage with the open-source community, owning and maintaining our repo.

Who you are

• 10+ years of backend engineering experience, with proven ability to scale high-traffic systems.
• Deep experience with developer infrastructure, APIs, databases, and performance-critical systems.
• Passion for developer tools, best practices, and building outstanding DX.
• Comfortable with Node.js and modern backend stacks.
• Strong communicator, proactive, and reliable in a remote-first environment.
• Product mindset and developer empathy: you optimize for DX.
• Pragmatic, positive, and low ego: you step up in incidents and unblock teammates.
• Startup-ready: autonomous, ownership-driven, and able to navigate ambiguity.

If you're a seasoned backend engineer who loves developer infrastructure, thrives on ownership, and wants to shape the future of integrations - we'd love to hear from you.
