Support Engineer

(Remote – GMT-3 to GMT-5)
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 350 paying customers rely on Nango today, including Replit, Mercor, and Exa. We are a YC-backed, multi-million ARR company with a team of 10 from AWS, GitHub, Snyk, Netlify, Uber, Samsara, and more.

We're looking for a Support Engineer to be the front line of the Nango customer experience. This role sits at the intersection of engineering, support, and solutions: You'll spend your days helping customers debug complex integration challenges, contributing code to expand our API coverage, and occasionally jumping on calls with prospects to show them what Nango can do.

This is not a traditional support role.
You'll read source code, dig through Datadog logs, trace auth flows across third-party APIs, and ship fixes. If you're an engineer who loves working directly with customers and thrives on variety, this is for you.

• Be the first point of contact for customers and prospects across email and Slack: triaging questions and driving issues to resolution with speed and clarity

• Debug complex platform and integration issues end-to-end: trace problems through Datadog logs and metrics, read Nango source code, and identify root causes

• Help customers troubleshoot implementation issues with external APIs (auth failures, problematic configurations, etc.)

• Implement support for new APIs on the Nango platform

• Maintain and improve API-specific documentation so customers can self-serve effectively

• Run technical Q&A calls with smaller prospects: help engineers understand Nango, map their integration ideas to Nango's primitives, and build confidence that it fits their use cases

• Contribute smaller code changes to the Nango platform: bug fixes, improvements, and quality-of-life changes that surface from support work

• Serve as a direct feedback loop into the product and engineering teams by surfacing patterns, gaps, and opportunities from customer interactions

• 5+ years of full-stack engineering or highly technical support experience, comfortable contributing code to a large codebase

• Enjoy working directly with customers and take pride in helping them succeed

• Excellent communicator with native-level English, able to build trust and clarity with technical teams

• Comfortable debugging complex systems and solving real-world integration challenges

• Able to multitask effectively and thrive in a fast-moving, high-ownership environment

• Professional, optimistic, and proactive: you represent Nango with speed, clarity, and excellence

• Comfortable with ambiguity and excited to operate at the heart of product and customer impact.

• Based in GMT-3 (Brazil/South America) to GMT-5 (Central time) time zones.

• Experience in developer tools, APIs, or integration platforms

• Prior work in customer-facing engineering or technical support roles

• Familiarity with OAuth flows, API auth patterns, and common SaaS APIs

• Startup experience in high-growth, high-velocity environments

This is a unique role for someone who combines strong engineering instincts with a genuine love for helping customers. You will be at the center of how people experience Nango: unblocking them today while feeding insights that shape the product tomorrow.

If you enjoy debugging hard problems, working across dozens of APIs, and making customers feel like they have a teammate on the inside, we would love to hear from you.
