We are looking to hire a full time fabricator that can mig and tig weld! If you can wrench that’s a huge plus we do mainly ls and lt platform. I do not have time to teach anyone to fabricate at the moment so you must be skilled enough to tackle turbo kits, exhaust, cold air intakes, etc yourself!

No tools needed for the welding unless you want to bring your hood and gloves.

Basic tools is needed for wrenching we have all the speciality tools that we use day to day.

Pay will be based off of experience

Message the business page if you’re interested!

As always thank you all for supporting us and helping us grow our team!
