The defense and security industry focuses on the design and development of products and services that the U.S. military and Department of Defense (DoD) can use to protect the country. Working closely with the aerospace and technology industries, this field produces new technologies and products to meet the increased need for stringent security including operations against physical, chemical, and biological threats, missile and cyber threats. These products are typically very expensive to produce so manufacturers contract with branches of the military or other government departments. Defense and security products can include anything from aircraft, military vehicles, missiles, weaponry, identity verification software, surveillance software, and more.
There are many companies that provide technology and equipment to military and security agencies as principal contractors. Defense manufacturers build:
Subcontractors, from very large to very small companies, supply components to principal contractors such as:
Parts
Supplies and Materials
Sub-assemblies
Sonar, Radio, Missiles, and Spacecraft
Defense and security is an ever growing and evolving industry, adapting and changing as new threats arise and dissipate. Because of these changes, many different specialties and backgrounds are needed. Individuals who work in this industry include scientists, engineers, computer and tech programmers, designers, architects, and even meteorologists.
The national security of the United States is organized by the federal government under the DoD, operating from Washington, D.C. A vast number of manufacturers contribute directly or indirectly to the country's defense efforts. The DoD employs its own staff of scientists, engineers, and researchers, who explore, design, develop, and implement many technologies vital to the country's national defense. The DoD also procures the manufacturing of all the necessary products, technologies, and materials supplied by commercial manufacturers that design and produce them.

RECRUITING TIMELINE
Depending on the type of employer and the role, recruitment timelines vary. Governmental organizations, large companies, and manufacturers recruit most heavily in the fall for positions starting in the spring or summer. Opportunities still exist beyond the fall but are often more niche opportunities with smaller companies. Additionally, companies will hire throughout the year depending on the needs and demands of their projects or government contracts.
Seek opportunities to connect with employers at fall events such as the fall Engineering Career Fair, as well as at employer table talks, employer-in-residence, Ask Alumni Anything chats, and student organization meetings.

Screening & Security Clearance
Many roles within the Defense + Security industry require screening for specific qualifications. Following the interview process, candidates are often offered a conditional job offer that is subject to completion of a suitability and security clearance process, designed to examine your life history to measure your loyalty to the United States, strength of character, trustworthiness, honesty, reliability, and soundness of judgment. The security clearance process is lengthy and previously obtained clearances make full-time candidates even more desirable. Be mindful of how your behaviors and online presence and interactions can impact your candidacy for roles within this field.
