The SI Career Opportunities

The SI…Our People, Our Priority

The SI knows that, without a doubt, our people make the difference. That’s why, along with Mission and Growth, our People are our top priority. We go a long way to assure that, from the moment you apply online to the time you arrive at orientation, you are made to feel like you are just that—a priority.

For starters, we understand that finding your next job shouldn’t be a job in itself, which is why our team of senior recruiters and hiring managers move quickly to make interviewing and hiring decisions. In many cases, it’s typical to have an interview and offer within the same week!

That being said, we will take as much time as you need to answer any questions you may have. Perhaps you want to know more about our exceptional benefits package, including our excellent tuition reimbursement program. Maybe you want to learn more about how our various Training/Career Development Programs are just one of the many reasons employees choose to stay with the SI.

If you are inspired by working alongside some of the most intelligent, creative and driven people in the industry in an environment where new ideas are encouraged at all levels, make the SI your priority today. We can’t wait to make you ours. Come out and meet us at one of our upcoming events.
