Engineering teams that keep programs moving
When customers partner with Performance Software, they gain more than added engineering resources — they gain responsive, collaborative software teams that expand capacity, ramp quickly, and keep complex aerospace, space, and defense programs moving forward. Our engineers bring deep aerospace domain expertise across requirements, architecture, design, development, integration, verification and validation, deployment, and sustainment.
With the previous supplier working the program, I lacked confidence that there was ever any meaningful progress being made. Now, with the Performance Software team running the program, I can clearly see the effort the team is putting in each week and can visualize that the program is steadily progressing towards accomplishing our goals.
— Leading A&D SupplierThe staff have consistently demonstrated exceptional capabilities, and the leadership team has provided outstanding engagement and support.
— A&D PrimeThe flight controls candidates have been better than some on my team as far as responsiveness, quality, and meeting schedules. Nicely done!
— Leading A&D SupplierVery happy with the resources provided — easy to work with the contractors and Performance Software leaders. Been a great help to the team!
— Leading A&D SupplierMove faster with AI, without sacrificing rigor
Space programs are under pressure to move faster while maintaining reliability, quality, and mission assurance. Performance uses AI-assisted engineering to help accelerate activities such as code comprehension, requirements analysis, documentation support, review preparation, test support, and regression analysis. Our engineers apply these tools within governed, secure development workflows — keeping human expertise at the center of every technical decision.
Programs need engineering partners who can scale speed and rigor together as the industry grows.
