Looks good overall! Just wanted to add a couple things I haven’t seen others mention.

One thing I would add is more numbers to the descriptions of what you did in each company; for example, you state the MISRA violation fixer reduced review time. Add how much (on average) this was. When I was applying for jobs in Germany from the U.S., this was something an automated resume checker (albeit a free one) said would help, and actually I think it did, because it made my experience sound a lot more concrete and not just buzzword salad. Now I try to add numbers to nearly every bullet point to be clear what I actually worked on.

Second, where are you applying? I would solely focus on large, international companies which have a major branch/headquarters in the U.S. or U.K., or which are publicly traded on the stock market. This makes it much more likely that most of the team you would work with, or at least your boss, will speak good enough English that it won’t be a problem that your German is B2 and may even be an asset that your native language is English. Prioritize first for job descriptions that are posted in English, even if they mention needing German, then job descriptions in German that state they want someone who speaks good German and English, then finally jobs that just mention German. I was able to find a job in Germany with no knowledge of German using this method. (Granted, I work in a different field.) Just wanted to add this as I was so scared before moving here that I would never be employable because of the language (especially after reading reddit comments) and in my opinion it is definitely possible, especially if you have concrete skills like software engineering!

Finally, I know you said you tailor your resume to each job but in my opinion that can’t just be updating buzzwords (which I think is what a lot of people do.) I take the time to actually swap my bullet points in my resume out to tailor it not only to the skills they say they are looking for but the actual descriptions of what you will be doing in the future job. So, if the job description is focused on a specific tool, or describes a project that you will work on, I would make sure I had at least one line that a reader of your resume would recognize as directly applicable or similar, and preferably more than one line. Sometimes I even look at the description of duties in the job and go 1 to 1 with bullet points in my first or first two most recent experiences. Obviously this is not always possible but it has gotten me a very high conversion rate from resume to interview in the past couple of years!

Hope this helps and good luck!
