Looking for work in Germany?

Having a German spouse you should be able to work. There are many foreign trades people in Germany so while speaking basic German is recommendable, you might be able to find work anyway. This will depend on the employer. Often there will be say a construction company that uses almost exclusively workers from a certain country like Poland, Greece etc. Usually this is because the owner or head manager is from said country. I am rather skeptical that one would find such employers that are mostly native English speakers but maybe ones that use people from a variety of countries and they all have English as their second language which is then used at the work place. But beyond getting a job, the more German you learn the happier you will be in the long run. Without passable German one tends to feel isolated and misses much of what is going on.

I am not an electrician so I don't know the rules about certification which will of course be important. You should research the subject in the internet and I would suggest you start with the German employment office known as the Bundesagentur für Arbeit or Arbeitsamt. They should be able to advise you about qualifications and certifications and possibly line you up with a job. I am posting a link to their English version page. Maybe you can familiarize yourself with the site and already find answers to most of your questions beforehand and then register with them once you are settled in Germany.
