Customer Success Engineer

Resend is building the modern email sending platform for developers, with over 3 million developers now using it and many customers coming specifically for a superior support experience. The fully remote team of 45 spans 13 countries and is backed by a16z and Y Combinator. As a Customer Success Engineer, you will extend the Success team to support the next wave of developers as demand grows across all time zones. This is a hands-on engineering role: you will debug real issues, ship real fixes, and turn recurring problems into permanent solutions.

Responsibilities

• Be the front line of customer requests, helping developers solve problems quickly.
• Debug, report, and ship scoped fixes for bugs and regressions.
• Turn recurring tickets into permanent fixes by shipping docs, product PRs, or agent improvements so the same question does not come back.
• Train and improve the AI support agent by refining prompts, adding tools, and running evals so more tickets resolve before reaching a human.
• Create guides and examples that showcase what is possible with Resend.
• Proactively build relationships and identify potential papercuts for customers.
• Advocate for customer needs to the greater Resend team.

Qualifications

• You love helping developers solve problems and can perform under customer pressure.
• 3-5 years of technical support or success experience.
• You have scaled support at a high-growth company, using automation and AI to grow resolution capacity faster than headcount.
• Experience improving email deliverability.
• Comfort with a modern tech stack including Next.js, Plain, Raycast, Retool, and Notion.
• An honest, low-ego approach with the autonomy to just ship it and take ownership of problems and solutions.
