Eos Interns at Play

Internship Testimonials

“The Business Development Internship with Eos was a unique opportunity to work in an exciting startup company with the potential to revolutionize the energy storage industry. During the internship I was able to work closely with, and learn from, the highly skilled management team and form strong connections within the intern team. Throughout the duration, I learnt a great deal about the process of commercializing a new technology as well as the US energy landscape more broadly.  I am excited to follow Eos’ progress as they continue to progress the technology and roll-out commercial installations.”
Laura, Harvard Business School MBA Class of 2015

“Entering my summer internship with Eos, I was thrilled to work with such an innovative and promising company. Immersing myself in the burgeoning energy storage industry was incredibly exciting, and it was really intriguing to see how a company could actively shape a growth industry. I was also seeking an intensive growth experience from my internship, and I knew that working for a startup would offer the dynamic and multidisciplinary learning environment I needed. My time with Eos certainly met and exceeded those expectations, but it was the tremendous talent and work ethic of the Eos team that made the experience especially rewarding.”
Alex Fuller-Young, Stern School of Business MBA Candidate Class of 2015

“I had a great experience working with the commercial team at Eos. One of the many benefits of working with a small, smart group is that you are given incredible responsibility during the summer – joining investor meetings, developing plans to enter new markets, writing grant proposals, etc. So the sky is the limit for your contributions. At the same time, I have yet to come across a company with a more complete understanding or innovative approach to energy storage. I learned far more in ten weeks than reading all the analyst reports and attending industry conferences. Overall, highly recommended.”
Matt Mo, Stanford Graduate School of Business Joint MBA & MA Class of 2014  

“The Business Development Internship with Eos Energy Storage is an intense, dynamic and multi-faceted program that will not only facilitate but demand your development as an energy industry professional. At Eos, interns collaborate directly with the senior management to elect several pivotal business development roles, which range from analytical to customer-facing, for which they will assume primary responsibility for the length of their term. For me, this program was integral to the crystallization of an expansive, yet unrefined, breadth of energy industry knowledge into relevant skills and enduring relationships with top industry players. I would absolutely recommend this internship to anyone looking to gain similar experience while actively contributing to the success of a game-changing energy industry start-up.”
Ryan Higgins, Pomona College Bachelor of Arts Class of 2014

“My internship with Eos was educational and enjoyable. Eos is doing incredibly valuable work, and interns have the chance to contribute in a meaningful way because it’s an intimate office with an entrepreneurial culture. Working with the Business Development team gave me real insight into how seasoned, successful professionals go about starting a new business. Eos’s interns have a lot of opportunities to take on responsibility and do independent work, even as an undergrad: I got the chance to write our business case for publication in a trade magazine, and helped redesign our website and marketing materials. I learned a lot about energy storage technologies and electricity markets, and honed practical skills like writing grants, sending out press releases, and managing social media. The people in the Business Development team are friendly, fun, smart, and interesting and eager to help you out in any way they can. I would definitely recommend interning with Eos.”
Ben Bleiberg, Pomona College BA Public Policy Analysis Class of 2015

“As a full-time graduate student, having the experience working with Eos’ Business Development team was immensely helpful in aiding my understanding of the business problems that can be solved by storage technology. Eos is one of the preeminent energy storage groups in the U.S. and management’s guidance and tutelage has been invaluable. Working with such a talented group of engineering, research, business development and investment professionals has bolstered my career trajectory and opened many doors for me in the energy industry.”
Jesse Petersen, New York University MS Global Affairs Class of 2014

“The business development internship with Eos is a unique opportunity to be fully involved and active in a broad range of activities often reserved for much more senior staff.  I was given ownership over critical functions like maintaining and improving the financial model.  I also was able to learn about start up business development by working side by side with senior leadership.  It’s a very active internship and as a result I was able to lean heavily on my experiences and learning from Eos when interviewing for full time positions.”
Adam Connaker, New York University MS Development Economics Class of 2014
