Summer Internships

Depending on the year and needs of our departments, CEI and our subsidiaries may offer project-based internship opportunities across the organization for undergraduate and graduate level students. The summer-long experience offers a unique opportunity to learn about the CDFI industry and to gain real, practical knowledge and understanding of CEI and our mission to create economically and environmentally healthy communities in which all people, especially those with low incomes, can reach their full potential.

Who we are:

Headquartered in Maine, CEI is a community development finance institution that is a national leader in rural economic and business development. CEI’s mission is to help grow good jobs, environmentally sustainable enterprises, and shared prosperity in Maine and in rural regions across the country by integrating financing, business and industry expertise, and policy solutions.

Over 70 percent of our financing and advice goes to businesses that are expanding opportunities for low-income communities, communities of color, and others who have been left behind by our economy.

What we believe:

• We believe that an engaging and supportive work environment advances our mission.

• We believe in utilizing the many varied talents of our staff and in providing continual opportunities for development.

• We believe in open communication, innovation, integrity and autonomy.

• We believe in equity and strive to create a culture where diverse people feel a sense of ownership and belonging, where they can be their authentic self.

• We believe in generosity, life balance and trust.

Our 2022 Summer Intern Program has been filled. Please check back next January!


CEI continues to place a high priority on the health and safety of our staff, our clients, and our communities. We continue to monitor and follow guidance from the Maine Centers for Disease Control and the US Centers for Disease Control.

CEI staff continue to work remotely. For staff who occasionally need to access our offices, we are adhering to indoor masking, proper hygiene and social distancing protocols. Any visitors to the office must adhere to these same protocols. We also maintain a staff and visitor log at our primary location in Brunswick.

Our Mission and Work

CEI believes that our economy should work for everyone. As a mission-driven investor, CEI works closely with the businesses we finance and advise to address operational, workforce, and environmental challenges, while deepening our impact in key industries, such as childcare, farming, aquaculture, clean energy and food manufacturing, that can contribute to an inclusive and environmentally sustainable economy. We also provide counseling and training for individuals and families, recognizing that building assets and managing debt, as well as a good job, are key ingredients for family financial security.

What to Expect

While learning about our industry, you’ll get hands-on experience in community development financing, business and programmatic consulting, professional development, knowledge sharing, and team collaboration.  As an intern at CEI or one of our subsidiaries, you’ll participate in departmental initiatives and complete a summer-long project that addresses issues within our sector.

We also know how to have fun! While the projects and the work can be intense, we like to ensure there is a balance between work and enjoying Maine in the summer. Interns have many chances to get together with each other and CEI staff for in-the-office and offsite activities, enjoy weekends off, paid holidays, and can flex their work schedules when necessary.
