Why Corvid:

Founded in 2004, we are a group of over 300 engineers and scientists, about three-quarters of whom hold Master's degrees or PhDs, that provide end-to-end solutions, including concept development, design and optimization, prototype build, test, and manufacture. We leverage the predictive capabilities of our high-fidelity computational physics solvers, indigenous massively parallel supercomputer system, prototyping plant, and ballistics and mechanics lab to investigate a variety of high-rate physics phenomena.

The results are complex engineering solutions for a range of applications: aircraft, ballistic missile defense, cybersecurity, motorsports, armor development, biological systems, and missile and warhead design and development. These results are achieved with optimal design and cost efficiency due to the predictive capability of Corvid's tools and our in-house, end-to-end integrated approach, which differentiates Corvid from the market.

We value our people and offer employees a broad range of benefits. Benefits for full-time employees include:

• Paid gym membership
• Flexible schedules
• Blue Cross Blue Shield insurance including Medical, Dental, and Vision
• 401(k) match up to 6%
• Three weeks starting PTO; increasing with tenure
• Continued education and training opportunities
• Uncapped incentive opportunities
