Freelance Software Engineer Internships Jobs in Indiana

Engineering Innovation, Inc. (EII) based in Lafayette, Indiana (just 20 minutes away from Purdue University) has been a premier provider of postal automation since 2006. EII is a small but growing dynamic company looking for highly motivated individuals to join its engineering team. The engineering team is responsible for the design, construction, testing, maintenance, and documentation of world-class postal automation equipment as well as assisting in defining the overall product direction.
We are currently seeking an Associate QA / Software Engineer, which is a part-time position for an engineering student or recent graduate. This position will be a hands-on engineering internship where you will design, build, test, and learn—while working alongside experienced engineers on real products and real problems. This position is great for someone that has a little bit of experience with both software and hardware and wants to work on improving their coding and testing skills.
We at Engineering Innovation strive to ensure that our relationship with our students/recent graduates is mutually beneficial and that they walk away from the experience with new-found knowledge and skills they can apply in their careers. We provide individual training for anyone that is hired, so do not hesitate to apply even if you are not 100% qualified. This is a paid (part-time) position.
