I’m applying for the Software Engineer position on Stripe’s Payments Infrastructure team. I’ve spent the last three years building backend systems at Datadog, and Stripe’s recent blog post on idempotency keys in distributed payment flows is exactly the kind of problem space I want to work in next.
At Datadog, I rebuilt our alerting pipeline to support 50,000 concurrent monitor checks, reducing false positives by 62% and eliminating a recurring on-call escalation that had plagued the team for two quarters. I also migrated our alert evaluation from polling to streaming with gRPC, cutting median latency from 4.2 seconds to 380 milliseconds. These projects taught me how to design for reliability at scale — the same muscle Stripe’s infrastructure demands.
Before Datadog, I was the sole backend engineer at a Series A fintech startup where I designed a transaction disputes system from scratch, handling 2,000+ disputes monthly with automated categorization that resolved 40% of cases without human review. Working in payments infrastructure at a smaller scale gave me an appreciation for the correctness guarantees that Stripe’s API provides to millions of businesses.
I’d welcome the chance to discuss how my experience with distributed systems and payment infrastructure could contribute to your team. I’m available for a conversation at your convenience.
Five things this cover letter does that most software engineer applications don’t.
Not just “a position at your company.” Jordan names the exact team (Payments Infrastructure) and references a specific Stripe blog post. This signals genuine research, not a mass application.
Instead of listing technologies, Jordan leads with the outcome: 50K concurrent checks, 62% fewer false positives. Numbers make the accomplishment concrete and give the reader a reason to keep going.
The fintech startup experience isn’t random — Jordan explicitly connects payment disputes work to Stripe’s mission. This makes the career progression feel intentional, not scattered.
The letter mentions gRPC, streaming, distributed systems — but always in the context of what they accomplished, not as a keyword dump. Every technology named is tied to a result.
No “I believe I would be a great fit” or “Thank you for your consideration.” Just a clear, professional ask for a conversation. Short, direct, and respectful of the reader’s time.
The weak version is a template that could be sent to any company. The strong version could only be sent to Stripe — and that specificity is what gets it read.
The weak version lists technologies and soft skills. The strong version shows one specific accomplishment with hard numbers. Hiring managers remember stories, not skill lists.
The weak close is a generic template ending. The strong close references the specific value the candidate brings and makes a clear, low-pressure ask.
