Here is your directory of defense contractors hiring near AEDC and what each company brings to the Tullahoma community.
Beyond New Horizons (BNH): The Primary AEDC Contractor
Beyond New Horizons, LLC is the largest single employer among AEDC contractors and the company most job seekers will encounter when searching for Arnold AFB positions. BNH holds the Test Operations and Sustainment II (TOS II) contract — the primary contract covering day-to-day operations, maintenance, and sustainment of AEDC's 68-plus test facilities.
Who they are. BNH is a joint venture of Astrion (formerly Belcan Federal) and Fluor Federal Services, Inc. The joint venture was formed specifically to compete for and execute the AEDC TOS II contract, which was awarded in March 2024. BNH is a member of the Tullahoma Area Chamber of Commerce and maintains its primary operations at Arnold AFB.
What they do. BNH personnel operate, maintain, and sustain AEDC's aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges, sled tracks, and other specialized test units. This covers everything from running a hypersonic wind tunnel test to maintaining the electrical infrastructure that powers the complex.
Who they hire. BNH positions span the full range of AEDC career fields: test engineers, mechanical and electrical engineers, Instrumentation Data and Control (ID&C) engineers, network engineers, database administrators, cybersecurity specialists, electricians, instrument technicians, aerospace machinists, crane operators, HVAC technicians, project managers, resource managers, and administrative staff. Salary ranges run from approximately $45,000 for entry-level craft positions to $140,000-plus for senior engineers and managers.
How to apply. BNH posts all openings through their career center at careers-bnh.icims.com. As of early 2026, Glassdoor lists over 100 BNH positions in the Arnold AFB area at any given time. Most positions require U.S. citizenship and the ability to obtain a security clearance.
Amentum (Formerly Jacobs Technology)
Amentum maintains a significant Tullahoma presence through its Advanced Solutions Group, which designs, constructs, and operates complex research and development facilities. Amentum's Tullahoma office is located at 600 William Northern Boulevard, and the company has operated in the area since Jacobs Technology established its local presence in 1999.
What they do. Amentum's Advanced Solutions Group specializes in wind tunnels, rocket test stands, climatic chambers, jet engine test cells, and acoustic chambers. Their work spans automotive, motorsports, defense, nuclear, and aerospace sectors — meaning Amentum employees in Tullahoma may work on AEDC-adjacent projects as well as commercial testing facilities worldwide.
Who they hire. Amentum seeks electrical and controls drafters, engineers with test facility experience, project managers, and technical specialists. Positions typically require engineering degrees or equivalent technical experience, with some requiring security clearances for defense-related work.
How to apply. Amentum posts positions through amentum.dejobs.org and major job boards including Indeed and Glassdoor.
Akima, LLC
Akima is a global enterprise with over 8,000 employees operating in multiple sectors including facilities management, IT services, and professional support. Akima maintains operations supporting AEDC at Arnold AFB and hires for positions ranging from facility maintenance to information technology.
What they do at AEDC. Akima provides facility support services including maintenance, custodial, grounds keeping, and infrastructure management. These services keep the physical plant running — the roads, buildings, grounds, and non-test infrastructure that support AEDC's mission.
Who they hire. Positions include facility maintenance technicians, custodial staff, grounds maintenance workers, and supervisory roles. Entry-level positions may require a high school diploma, driver's license, and basic computer skills, making Akima a pathway to AEDC employment for workers without engineering degrees.
Abacus Technology Corporation
Abacus Technology provides information technology and cybersecurity services supporting AEDC's network infrastructure. As military installations face increasing cybersecurity requirements, Abacus's role has become increasingly critical to AEDC operations.
What they do at AEDC. Abacus manages COMSEC (Communications Security) operations, maintains classified and unclassified network infrastructure, and provides cybersecurity monitoring and compliance services. They ensure the confidentiality, integrity, and availability of information across AEDC's government networks.
Who they hire. Cybersecurity specialists, COMSEC custodians, network administrators, system administrators, and IT support professionals. These positions typically require security clearances and relevant IT certifications (CompTIA Security+, CISSP, or equivalent). Salary ranges for IT security positions at AEDC typically fall between $65,000 and $120,000.
National Aerospace Solutions (NAS)
National Aerospace Solutions, LLC — a team consisting of Bechtel National Inc., Sierra Lobo Inc., and GP Strategies Corporation — previously held the primary TOS contract at AEDC before the transition to BNH. While NAS lost the TOS II competition in 2024 (a protest to the Government Accountability Office was denied in July 2024), NAS personnel with AEDC experience remain in the Tullahoma talent pool, and some NAS team members transitioned to BNH or other contractors during the contract changeover.
Why this matters for the community. Contract transitions are a normal part of the defense contracting cycle. When a new contractor wins the primary AEDC contract, the incoming company typically hires a large percentage of the incumbent workforce — the people who know the facilities and the work do not disappear. This creates temporary employment uncertainty but rarely results in significant job losses to the community. The talent stays in Tullahoma.
Canvas II, LLC and Additional Small Businesses
Beyond the major contractors, dozens of small businesses support AEDC operations as subcontractors and vendors. The Arnold AFB Small Business Office (located at 100 Kindel Drive, Suite A332, Arnold AFB, TN 37389, phone 931-454-4405) actively works with small businesses interested in serving as suppliers, vendors, and subcontractors.
Types of small business opportunities. Calibration services, specialty machining, environmental remediation, construction and renovation, IT consulting, training and education services, and administrative support. Small businesses with relevant capabilities can register through SAM.gov (System for Award Management) and contact the Small Business Office directly for information about upcoming procurement opportunities.
The Contractor Ecosystem's Effect on Housing
The diversity of AEDC's contractor ecosystem creates specific patterns in the Tullahoma housing market.
Steady demand across price points. BNH engineers earning $100,000-plus drive demand for premium neighborhoods like Bel-Aire and Park City ($350,000 to $500,000). Akima facility workers and entry-level technicians create demand for homes in the $175,000 to $275,000 range. This full-spectrum demand supports property values across the entire market — not just at the top.
Relocation-driven buying. When a new contractor wins a major AEDC contract, they often bring management and specialized personnel from other locations. These relocating professionals become immediate home buyers, creating predictable spikes in housing demand that coincide with contract transitions.
Security clearance premium. Cleared professionals — who represent the majority of AEDC's workforce — tend to be stable, long-term employees with consistent income. Lenders view cleared defense workers favorably, and these buyers qualify for strong mortgage terms. From a housing market perspective, AEDC's cleared workforce represents an unusually creditworthy buyer pool for a small Tennessee town.
How to Start Your AEDC Job Search
Step 1: Identify your target companies. Start with BNH (careers-bnh.icims.com) as the primary contractor, then check Amentum, Akima, and Abacus. Also search ClearanceJobs.com for positions requiring active clearances.
Step 2: Check federal civilian postings. USAJobs.gov lists all DoD civilian positions at Arnold AFB. Federal positions offer stability, benefits, and retirement advantages that contractor positions may not match.
Step 3: Leverage specialized job boards. ClearanceJobs.com, Indeed (search "Arnold AFB" or "AEDC"), Glassdoor, and ZipRecruiter all list current openings. Set up job alerts to catch new postings as they appear.
Step 4: Get your housing lined up early. Tullahoma's housing supply has been tight for AEDC workers in recent years. If you receive a job offer, begin your home search immediately — do not wait until your start date to begin looking. A mortgage pre-approval before you start looking ensures you can move quickly when you find the right home.
