Its core offerings are: - **IT Enterprise Solutions**: Design, implementation, sustainment, and management of IT infrastructure for federal agencies. - **Cyber Security Services**: Cyber security support, compliance, and engineering (e.g., PAM, SOAR, SOC/NOC operations). - **Strategic & Management Consulting**: Agile capability-driven approach to solve analytical and operational challenges. - **Instructional Design & Training**: Computer training, professional development, and educational support services. - **Enterprise Application Development**: Custom software development and systems integration. ## Market Standing - **Valuation / Market Cap**: Not disclosed (private company) - **Key Metric**: Annual Revenue – USD **$24.9 million** (LinkedIn estimate) - **Notable Investors / Partners**: No external investors; key clients include the U.S. Department of Veterans Affairs, U.S. Army, and U.S. Navy. In 2023, MKS2 won a **$221 million Army contract** for the Transition Assistance Program. - **Growth Signals**: Named to the **Inc. 5000** list in 2024 (ranked #3,037 overall, #92 in Government Services). However, headcount declined 49% year-over-year to 143 employees, signaling a possible restructuring or shift toward higher-value contracts. ## Competitive Advantages - **SDVOSB Certification**: Provides preferential status in federal contracting. - **Founder’s Military Background**: Founded by a former combat veteran and West Point graduate, the company’s values align with federal mission needs. - **Deep Federal Network**: Long-standing relationships across intelligence, national security, and civilian agencies. - **Agile Methodology**: A capability-driven, rapid-response approach that differentiates it from traditional integrators. ## Strategic Focus - **Current Priorities**: Expanding support for defense and veteran-related programs (e.g., Transition Assistance Program), maintaining key federal contracts, and recruiting cleared technical talent. - **Growth Direction**: Likely to deepen its footprint in cyber security, cloud engineering, and automation (SOAR, Dynatrace) while leveraging its small business status to win set-aside contracts. ## Why Work Here - **Culture**: “Collaborative & Innovative,” with a focus on employee well-being and open communication. The company emphasizes that “the most important asset of any organization is its people.” - **Work Environment**: Hybrid/remote opportunities exist for some roles (e.g., Dynatrace Instrumentation Engineer is remote), but many positions require on-site support at federal locations (e.g., Washington DC, Annapolis Junction, Tucson). Personnel are located in 43+ states plus overseas (Germany, Italy, South Korea). - **Benefits**: Comprehensive benefits (health, dental, life) starting the first of the month after hire; bonus programs (signing, time-in-grade, performance); 15+ days of paid time off; educational assistance (class reimbursement, college debt programs, professional development, book buy-back). - **Engineering Culture**: Focus on technical roles like cyber security, systems engineering, and software development. Employees often come from or go to other defense contractors (General Dynamics, Booz Allen, Serco). The company values long-term commitment and professional growth. ## Sources 1.
