## Products & Services
- **SCEPTRE**: A flagship program focused on guided munitions and advanced missiles, designed for precision and scalability.
- **GRAIL**: An AI-enabled lethality and autonomous platform program, involving software products for next-generation defense systems.
- **LAB**: Tiberius's continuous innovation engine that separates R&D from manufacturing, enabling rapid iteration and sovereign scalability.
- **DAAS (Defense-as-a-Service)**: The company's core operating model—a radically different approach that decouples R&D from production to allow faster adaptation, cost-effective lethality, and continuous evolution of systems.

- **Growth Signals**: Headcount grew **366.7% year-over-year** to 21 employees; actively hiring across multiple engineering and operations roles; distributed workforce across the US and UK; flagship programs (SCEPTRE, GRAIL) are operational and scaling.

## Competitive Advantages
- **Defense-as-a-Service (DaaS) model**: A unique approach that separates R&D from manufacturing, allowing for rapid iteration, sovereign scalability, and continuous innovation—a stark contrast to traditional prime defense contractors.
- **Speed and adaptability**: Designed for a new era of conflict where speed and cost-effective lethality are critical; the company's ethos is to "adapt faster than emerging threats."
- **AI and software-first mindset**: Leadership and talent come from companies where rapid iteration, software, and AI were the norm; this mindset is applied to hardware and defense systems, creating continuously learning and evolving platforms.
- **Talent acquisition from top defense primes**: Key hires from Raytheon (6 employees), NASA Jet Propulsion Laboratory, and other defense tech companies, bringing deep domain expertise.

## Strategic Focus
- **Current priorities**: Scaling the SCEPTRE and GRAIL programs; expanding sovereign manufacturing capabilities for the UK and US; building a continuously learning ecosystem that connects engineers, manufacturers, operators, and governments.
- **Direction for growth**: Global expansion with allied nations; deepening AI and autonomous capabilities; moving from seed-stage to production and deployment at scale.

## Why Work Here
- **Culture**: A mission-driven environment focused on "difficult problems" with real-world impact at global scale. The company emphasizes that "software can transform hardware" and is building a new model for defense.
- **Remote/Hybrid policy**: Offers remote, hybrid, and on-site work options depending on the role. Many positions are fully remote; engineering roles (e.g., Test Engineer, GNC Engineer) in Tucson, AZ are on-site.
- **Notable perks**:
