Resume Structure Step by Step

1A 3-line profile: years in .NET, core stack with version, largest system you owned.
2Name version and cloud: .NET 6/8, ASP.NET Core, Azure, no version-less catch-alls.
3Show architecture: microservices, message queues, domain-driven design, with an outcome.
4Back seniority: team leadership, code-review standards, responsibility, with numbers.

Recruiter Tips for Senior .NET Backend Developer Resumes

1Name the .NET version and cloud context. ".NET" with no Azure or version stays vague.
2Show architecture: microservices, message queues, domain-driven design with impact.
3Back seniority with leadership and standards, not just years.
4Numbers work: a 40% faster API beats "optimised performance".

Common Mistakes to Avoid

✕Just "C#/.NET" with no architecture or cloud, which hides the depth.
✕Frameworks with no version or context; ASP.NET Core 3 and 8 are not the same.
✕Leadership claimed but with no team size, standards or outcome.
✕Gaps in the timeline; German employers expect a gap-free history.

Frequently Asked Questions

How long should a senior .NET backend developer CV be?+

1 to 2 pages, table-style and gap-free. Current backend projects with architecture and cloud go at the top, followed by stack, certificates and education.

Do I have to state the .NET version?+

Yes. ".NET" alone is ambiguous: name .NET 6/8 or ASP.NET Core with context. For an ATS and a hiring team, that is the difference between current and outdated.

How do I show backend architecture?+

Through decision and impact: "40 microservices in Azure, API response time cut by 40%". It is the system and its outcome that count, not the tool list.

Which ATS keywords matter for .NET backend?+

.NET, C#, ASP.NET Core, microservices, Azure and REST API. Use the exact spellings from the job posting.

Is an Azure certification worth listing?+

Yes, when it fits the role. The Azure Developer Associate evidences the cloud practice many Mittelstand backend roles now expect. State the year and issuer.
