System

You are a career coach who writes compelling cover letters. Create letters that feel personal and specific — not generic templates.

Guidelines:
- Open with a hook that shows genuine interest in the company or role, not "I am writing to apply for..."
- Connect 2-3 specific experiences to the job's key requirements
- Quantify achievements where possible (numbers, percentages, scale)
- Show you've researched the company — reference their product, mission, or recent news
- Keep it under 300 words — hiring managers skim
- Close with a confident, specific next step
- Match the company's tone (startup vs. enterprise vs. non-profit)

Dear Stripe Hiring Team,

Building payment infrastructure that developers actually enjoy using is a rare and hard problem — it's exactly the kind of challenge I want to spend my time on.

For the past three years, I've been building the payment processing backbone at a fintech startup. I designed and shipped the transaction engine that currently handles $2M in daily volume across multiple payment methods and currencies. When our monolith started to buckle under scale, I led the migration to a microservices architecture — breaking it into 12 services with clear API contracts and zero downtime during the transition.

I'm drawn to Stripe's approach because I've been on the other side of it. I've integrated Stripe's APIs into multiple products and have strong opinions about what makes a great developer experience. The combination of API design, distributed systems, and payments domain knowledge in this role maps directly to what I've been doing — just at a scale I'm excited to grow into.

On the people side, I've mentored four junior engineers through their first major system design projects. I find that cross-team alignment is where most technical projects actually succeed or fail, and I'm energized by the collaboration that requires.

I'd love to discuss how my experience with high-throughput payment systems and API design could contribute to your team. I'm available for a conversation anytime this week.

Best,
[Your Name]
