Bewerbung als Senior Backend Engineer (m/w/d), Kennziffer KM-2026-114
Sehr geehrte Frau Hoffmann,
Kranich Mobility baut seine Buchungsplattform von einem großen System in viele kleine Services um. Diesen Weg bin ich bei der Brightloom GmbH schon einmal gegangen: Dort habe ich die Migration von 14 Services von einem PHP-Monolithen zu Go auf Kubernetes geleitet.
In Ihrer Anzeige suchen Sie jemanden, der Störungen von der ersten Warnung bis zur Nachbesprechung verantwortet. Ich habe die Rufbereitschaft für 6 Teams eingeführt; in zwei Quartalen gingen die Störungen um 40 % zurück.
Bei der Seewind Reisen AG habe ich den Zahlungsprozess mit Event Sourcing neu gebaut und Prometheus und Grafana in 40 Services eingeführt. Kafka und PostgreSQL gehören seit Jahren zu meinem Alltag.
Ich arbeite gern mit Menschen, die gerade wachsen: 4 Entwickler habe ich betreut, 2 davon wurden innerhalb von 18 Monaten Senior. Ich kann zum 1. Januar 2027 starten und freue mich auf ein Gespräch.
Mit freundlichen Grüßen
Marko Weber

Structure
Opening, body, close.
Three parts on one page. Each has a job, and every sentence has to do it. This is how you build a letter that sounds like this job and not like a template.
Opening
One sentence that shows you mean exactly this job. Start with the company, the project or the problem from the ad, not with “I hereby apply”.
ExampleYour platform schedules thousands of deliveries in real time every day. That is exactly the type of system I have spent the last seven years building.
Body
One or two paragraphs: what does the job ask for, and which of your experiences fits? Give one or two concrete results with a number or proof, and point to your CV instead of repeating it.
ExampleAt Ostwerk, I introduced on-call rotations for six engineering teams and cut production incidents by 40% in two quarters.
Close
Give the earliest start date or your notice period, and the next step, a conversation. No filler, no “unfortunately” or “possibly”.
ExampleI look forward to discussing how my experience in distributed systems can support your infrastructure goals.
Examples
Three openings for three situations.
The sample paragraphs illustrate how to connect your experience to the job requirements. Adapt the concepts with your own achievements.
Career start
During my logistics internship, I migrated shipment tracking for 200 client accounts from a spreadsheet into an automated analytics dashboard. I am excited to bring this analytical rigor to your Junior Data Analyst role.Why it works: An internship counts when it fits the job. The paragraph names the task, the scale and the result, and says which role the application is for.
Career change
Five years in classroom teaching taught me how to break down complex technical topics into intuitive concepts. For your Onboarding team, I developed and led comprehensive onboarding courses for 60 new colleagues.Why it works: The paragraph translates the former job into a skill the new role needs, and proves it with a concrete task.
A move with experience
After eight years in enterprise software sales, I want to transition into product management to guide customer solutions directly. In my current role, I manage twelve enterprise accounts while maintaining high retention.Why it works: The wish to move is explained as a direction, not an escape. A current number shows that the work so far holds up.
FAQ
Questions about cover letters
Does it make up experience?
No. The letter uses facts from your career profile and the job ad. You see every sentence before you send it, and you can edit or delete any of them.
Can I write it in German and English?
Yes. Pick the language before you draft, or translate a finished letter for 11 credits. The layout stays.
What does a letter cost?
6 credits per letter, shown on the button before you click. If you reject the draft, the credits come back.
Does it adapt to international and German standards?
Yes. English letters follow clean modern business standards; German letters automatically follow the DIN 5008 structure with header, address, date, and subject blocks.
How long is a cover letter?
Usually one page with three or four short paragraphs. One thought per paragraph beats one block. You do not have to repeat what is in your CV.
Whom do I address if the ad names nobody?
Ask if you can: a call or a short email to the HR team will give you the name. If that fails, write “Sehr geehrte Damen und Herren,”. At startups, “Guten Tag,” is common too.
Do I have to name a salary in the letter?
Only if the ad asks for it. Then give a range as annual gross in the last paragraph. If the ad asks for nothing, keep the topic for the interview.
