Nango

(YC W23) is a developer infrastructure company and the leading provider of API access for agents and apps. It enables AI applications to connect to the real world through integrations.

More than 400 paying customers rely on Nango today, including Replit, Ramp, Mercor, Vapi, Instantly, and Exa. We are a YC-backed, multi-million ARR company with a team of 14 from AWS, Snyk, GitHub, Okta, Netlify, Uber, Samsara, and more.

We are hiring Senior & Staff Backend Engineers to join the core engineering team building Nango’s platform and developer infrastructure. This is a critical role at the heart of the company: as a product-led business selling to developers, our engineers directly drive the product roadmap, specifications, and execution. You will own core systems end-to-end, from ideation and design to implementation and close collaboration with developer customers, shaping both the platform and how Nango evolves.

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
• 5+ years (senior-level) or 10+ years (staff-level) 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.
• Based in North America, LATAM or Europe.
• 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.
