This year's awards were given to Jessica McKellar, director of engineering and chief of staff to the vice-president of engineering at Dropbox, and Preeti Murthy, a graduate student at Carnegie Mellon University.
Nominations for the awards were accepted in two categories - academic and community - and presented at the annual Red Hat summit that took place in San Francisco in the last week of June.
McKellar began making contributions to open source as an intern at VMware before becoming a kernel engineer at Ksplice. She has involved in open source software development for seven years.
She delivered a keynote at PyCon 2014 on the importance of programming education for young children, and ran a Python development sprint for new women contributors in San Francisco.
Murthy, who was recognised in the academic category, is studying for a master's degree in electrical and computer engineering and has been an open source contributor for more than three years.
As an undergraduate, she worked on the Mono open source cross-compiler project as part of her thesis.
Murthy joined IBM's Linux Technology Centre soon after earning her bachelor's degree, where she worked for three years as a kernel developer. Her open source contributions include code, documentation, tutorials, and open content.
Winners will get a stipend of US$2500, with the suggested use being to support open source projects.
