Cover letter sample
Dear Hiring Manager,
I am excited to apply for the Senior Customer Support Engineer position at Vercel. With a strong background in technical troubleshooting, modern web development, and AI-powered applications, I am drawn to Vercel's mission of empowering builders and agents. I have hands-on experience with Next.js and have built LLM-powered apps, which aligns with your focus on v0 and the AI SDK.
In my previous role, I specialized in resolving complex customer cases while developing scripts and tools to reduce recurring issues. I enjoy digging into root causes and collaborating with engineering and product teams to drive lasting fixes. My ability to explain technical concepts clearly has helped me earn trust with enterprise customers and internal stakeholders alike.
I am comfortable working in a fast-paced, remote-first environment and am willing to participate in on-call rotations. I would love the opportunity to bring my customer passion and technical expertise to Vercel's support engineering team.
Thank you for your consideration.
Sample interview questions
I had a case where a customer's production app was intermittently failing due to a misconfigured caching layer. I worked with the engineering team to reproduce the issue, identified that the caching headers were being overwritten, and implemented a temporary workaround while we created a permanent fix. I communicated clearly with the customer throughout and documented the solution in a runbook.
I would start by reviewing their project configuration, build logs, and performance metrics in the Vercel dashboard. I'd check for common issues like unoptimized images, missing caching headers, or large bundle sizes. If needed, I'd reproduce locally using `next build` and profile with tools like Lighthouse. Then I'd provide actionable recommendations and escalate to engineering if the issue is platform-related.
I've built applications using the OpenAI API and LangChain, and I've worked with v0 to generate UI components. I stay updated by following AI community forums, reading research papers, and experimenting with new SDKs. I understand concepts like token limits, prompt engineering, and latency optimization, which allows me to support customers effectively.
I would empathize with the customer, acknowledge their urgency, and provide a timeline for the escalation. I'd keep them updated regularly and ensure they have a temporary workaround if possible. I'd also document their case thoroughly so engineering has all the context, and I'd follow up after the fix to ensure satisfaction.
I rely on asynchronous tools like Slack and Linear, but I also schedule regular syncs when needed. I make my documentation detailed and actionable, and I'm proactive in sharing updates. I use screen recordings to demonstrate complex issues, and I always assume positive intent in written communication to avoid misunderstandings.
