Stax Inc., a global strategy consulting firm serving industry-leading corporate and private equity clients, is expanding our Data Science team. Stax is a fast-paced firm, where actionable results and quality work are valued, and time spent on client sites is kept to a minimum. At all levels of the organization, our people are bright, driven, and able to excel. 


During your time at Stax, you’ll consistently face intellectually challenging projects with clients that range from Fortune 500 companies to the largest LBO firms globally. Working across a wide spectrum of industries on short-term engagements designed to last 4-12 weeks, you’ll gain new hand-on experiences with each project you encounter.


At Stax, you’ll also have incredible opportunities to build your consulting career. Our staff works side by side with—and learns from—some of the smartest people in the business. Our entrepreneurial approach to work and broad client base creates immediate opportunities for client exposure, providing enormous potential for career progression. Associates work directly with all levels of the firm to diagnose our clients’ most pressing issues while identifying new opportunities for value creation and accelerating growth.


Life at Stax is unique - our goal is to empower and challenge employees, while supporting a reasonable work/life balance. No question: you’ll work hard. However, unlike other firms where you might uproot your life for weeks or months at a time, our team spends far less time on the road. As such, creating time for professional and personal development, allowing great people and teams to grow as well as get involved in our communities.


Our entire staff is intelligent, innovative and - most importantly - willing to roll up their sleeves. If you’re willing to dive in, work with talented team members and drive impact from day one, Stax is the perfect environment for you. 


At Stax, we have a clear mission: to be the place where a diverse mix of talented people want to come, to stay, and do their best work. From such diversity and inclusion comes our unique innovation and actionable insights.
