Ms. Laura Chen
Engineering Manager
Northwind Software
2-1-1 Otemachi, Chiyoda-ku, Tokyo

Dear Ms. Chen,

I am writing to apply for the Backend Engineer position at Northwind Software, which I found on your careers page. I have spent the past six years building payment systems in Go and Python, and this is the kind of product I want to work on next.

At Rakuten, I rebuilt the billing service that handles about 400,000 transactions a day and cut error rates by 60% in the first quarter after release. I am comfortable taking a project from the first design review to the release, and I work well with teams in other time zones. Most of my code reviews and design documents over the past three years have been in English.

What Northwind is building lines up closely with the work I have been doing, so I would not need long to be useful. I have also read your engineering blog since the migration series last year, and the way your team writes about trade-offs is the main reason I am applying.

I would welcome the chance to talk about how I could help your team. I am currently employed, so I would need about a month to hand over my work, though I can be flexible on the date. You can reach me at kenji.sato@example.com or +81 90-1234-5678. Thank you for your time and consideration.

Sincerely,

Kenji Sato

Dear Hiring Manager,

I am writing to apply for the Digital Marketing Manager position at Brightline, which I found on LinkedIn. I have worked in B2C digital marketing for eight years, most recently on subscription products.

In my current role at Lumen Japan, I ran the paid social program across four markets and grew monthly signups by 42% while keeping the cost per acquisition flat. I make decisions from numbers rather than from assumptions, and I spend time with customers and turn what they say into concrete changes. I also rebuilt our reporting so that the sales team could see campaign results the next morning instead of two weeks later.

Brightline is at a stage where one person can still change how things work, and that is where I do my best work. I have been using your app since the redesign, and the onboarding flow is the clearest one I have seen in this category.

I would really like to talk with you about this role, and I can make time for a call whenever it works for you. I am available to start immediately. You can reach me at aya.morimoto@example.com or +81 80-2345-6789. Thank you for your time and consideration.

Best regards,

Aya Morimoto

Taylor Brooks
Head of Customer Success
Havenly Cloud
1-6-1 Roppongi, Minato-ku, Tokyo

Dear Taylor Brooks,

I am writing to apply for the Customer Success Manager position at Havenly Cloud, which I found through a former colleague on your support team. I have spent the past five years looking after enterprise accounts in Japan, and I would like to do that work for a product I already use.

At Zenith Systems, I managed 38 enterprise accounts worth 620 million yen a year and lifted renewal rates from 84% to 96% over two years. I work in both Japanese and English every day, which matters here because most of my accounts were Japanese while the product team sat in Seattle. When a renewal was at risk, I was usually the person translating between what the customer said and what the product team needed to hear.

The problem Havenly Cloud is working on is one I care about, and I would rather work on it than watch from the outside. I have been the customer on the other side of this product for three years, so I know where new users get stuck.

I would welcome the chance to talk about how I could help your team. I am currently employed, so I would need about a month to hand over my accounts, though I can be flexible on the date. You can reach me at sho.nakamura@example.com or +81 70-3456-7890. Thank you for your time and consideration.

Sincerely,

Sho Nakamura
