At GDIT, our people are our business. We pride ourselves on the work our innovators do to support and secure some of the most complex government, defense, and intelligence projects across the world. We wouldn’t be successful without our ability to attract new talent to join our team. 

What sets a GDIT internship experience apart from other organizations in the industry? 

GDIT’s Summer Internship Program is designed with you in mind!  Our internship provides you the opportunity to be a part of a collaborative team that is helping to solve our clients’ most challenging matters. Throughout GDIT’s 10-week Summer Internship Program, you will have the opportunity to do the following: 

• Work side-by-side with GDIT professionals delivering work for clients.  

• Collaborate with a team of peers to research and propose solutions to a current business challenge.  

• Participate in a mentoring circle led by an early career champion. 

• Interact with GDIT leaders. 

• Participate in professional development. 

How You’ll Make this Internship Opportunity Your Own 

GDIT is seeking a motivated and detail-oriented Proposal Writing Intern with a strong interest in technology and a passion for persuasive writing. This role is ideal for someone who enjoys researching complex topics, distilling technical information into clear and compelling content, and contributing to high-impact business development efforts.

The ideal candidate is a strong communicator, intellectually curious, and eager to gain hands-on experience in federal proposal writing.

A Day in the Life  

• Assist in crafting concise, solution-focused responses, primarily supporting IT enterprise acquisitions in areas like Software Development, Data Science, Systems, and Cloud Engineering.
• Assist in conducting research and integrating content from technical SMEs, past proposals, and publicly available sources.
• Manage the entire proposal process, including timelines and submission requirements.
• Assist in final production of proposal content, to include editing and formatting.

• Work with internal and external writers that include teaming partners, subject matter experts, project managers, and solution architects to produce proposal content.
• Assist in developing staffing matrices for proposal submissions, including mapping labor categories, estimating level of effort, and aligning personnel qualifications with project requirements to support competitive and compliant bids.
• Support the development of cost volumes for proposal submissions, including gathering pricing data, preparing cost models, and ensuring alignment with solicitation requirements, pricing strategies, and compliance standards.
• Participate in special projects as required.

What You’ll Need to Deliver Your Best Every Day 

• Strong research skills, with the ability to synthesize information from various sources to support proposal content.
• Ability to build meaningful relationships with managers and members of your team. 

• Be self-aware enough to identify and correct your mistakes and not be afraid to ask for help when needed.

• Prioritize tasks and responsibilities. 

• Basic understanding of Microsoft Office products (e.g., Word, PowerPoint, SharePoint, Excel, and Teams).

The Must-Haves 

• Currently enrolled in an associate's, bachelor's or master's degree program in English, Communications, or a related field from a United States-based college or university. 
• Superior writing, editing, and proofreading skills with an ability to grasp and articulate concepts succinctly.
• Ability to interpret solicitation documents (SOWs) and help ensure compliance with proposal requirements.

What Will Make You a Stand-Out Candidate 

• Basic understanding of fundamental IT enterprise concepts (e.g., cloud, infrastructure, software development), with the ability to follow technical discussions and convey concepts in proposals.
• Basic understanding of federal acquisition processes and terminology (e.g., FAR, proposal volumes, LCATs), or a strong willingness to learn.

The likely hourly rate for this position is between $25.50 - $34.50. This is not, however, a guarantee of compensation or salary. Rather, salary will be set based on experience, geographic location and possibly contractual requirements and could fall outside of this range.
