What You’ll Be LaunchingAs a Proposal Manager, you will independently manage the full lifecycle of government and commercial proposals of moderate size and complexity. You will serve as the central organizer and driver of proposal efforts, translating solicitation requirements into clear plans, coordinating cross-functional contributors, and ensuring compliant, high-quality, and on-time submissions.

What We Do
Slingshot Aerospace builds world-class space simulation and analytics solutions. We are driven by our vision of accelerating space sustainability to create a safer, more connected world.
Space is increasingly complex due to the exponential growth of global launch activity, the proliferation of new data sources, and the ever-growing body of new satellites and debris. Organizations are making mission-critical decisions in this high-risk environment and they need the right information at the right time. Slingshot Aerospace empowers government and commercial space organizations to better design, manage, and safeguard their assets, as well as mitigate risks, to ensure safe and reliable operations for all space-faring users.
We are achieving this by bringing the space domain into the digital environment and fusing together data from different sources to provide a full, dynamic orbital picture. In doing so, Slingshot Aerospace customers can make decisions at the speed of relevance and achieve clarity in complex environments.
