Our government affairs internship provides students and graduates with a variety of learning experiences and an inside look at government relations strategies. We have successfully accommodated students from second-year undergraduate programs to second-year law students and master’s degree graduates. We seek to ensure that interns who successfully complete our program are prepared to both succeed in entry-level policy positions as well as gain a deeper academic comprehension of the institutions that govern our country. Cornerstone’s Intern Program emphasizes effective communications, policy analysis, and research and writing skills.

While our program is perfect for a candidate who can commit to a full-time work schedule, we also regularly accommodate part-time interns as long as they can commit to working full days.  For federal government relations, our internships are fully in-person in our DC office.

Preferred Qualifications:

• • Demonstrated interest in government and public policy
  • Very strong writing and research skills

OpsWatch Intern

OpsWatch is a specialized offering within Cornerstone that provides grant monitoring services across a broad set of industry sectors. Our OpsWatch team monitors a large net of federal grant opportunities and provides individualized client guidance on those opportunities most worth pursuing. In practice, the OpsWatch team pulls information from key sites like grants.gov and creates various tailored reports for clients like universities, municipalities, nonprofit foundations, national security and defense companies.

The OpsWatch team also increasingly runs point on reading, summarizing and categorizing large omnibus bills to produce critical and timely analyses for clients and the firm at large.

OpsWatch interns get a unique insight into how federal funding mechanisms work (i.e. formula and competitive funding), and how they connect to broader policy work that Cornerstone does with respect to congressional activity, appropriations, etc.

In addition, OpsWatch interns have the opportunity to do meaningful work and contribute substantially to client-facing work products. They will also be integral to OpsWatch as it works to expand its offering within Cornerstone by helping to reimagine the role OpsWatch can have in meeting client needs.
