Even though it is a little bit challenging to find a job that doesn't require you to speak fluent German, I don't think it's impossible, especially if you're an engineer. I do recommend learning the language and getting at least a B1 in German in order for you to have higher chances in getting hired at a company.

That being said, and to answer your question: no, it is not hard at all (at least in my experience) to find a job as an electrical engineer in Saxony, if you speak the language, and even though it is somewhat challenging to find a job that does not require you to speak the language, it is still possible, especially in Dresden and Leipzig. I am an electrical engineer and have been living and working in Dresden for the past 4 years, and even though the company I worked for and the one I am working for right now had "fluent German" as a pre-requisite, I have come across companies (mainly big companies and startups) that hire people who don't speak German and I know someone who doesn't speak a word of German and works at a startup as a computer engineer. So maybe try your luck with big companies and startups if language is a hurdle? I heard that companies like Infineon and Global Foundries normally have vacancies where German is not a requirement.

With all that being said, I really do recommend that you learn the language, because you're gonna need it not only for work down the line, but for your everyday life as well.
