It’s time again to recognize the people who literally make the tech world function.

This is the fifth year that is recognizing influential technologists in our community who show impressive technical aptitude, community leadership and collaborative practices, aka our RealLIST Engineers. These people are software engineers, IT directors, cybersecurity pros and more, but what they all have in common is a passion for tech and a desire to spread their knowledge through volunteering, public speaking, mentorship and the like. spent the last few weeks gathering nominations from our community and reviewing the past year of reporting before narrowing it down to this list. Click to see the 2022, 2021, 2020 and 2019 editions. Spoiler alert: We were tasked with keeping this one to just 15 technologists, but you’ll spot two co-leaders of one org, so technically there are 16 on this list. More to love, right?

Without further ado, check out this year’s RealLIST Engineers.
