At Slingshot Aerospace, we're on a mission to make space safer and more secure for everyone. Our work directly impacts global security, disaster response, climate monitoring, and the critical infrastructure that connects our world. We're a team of builders, thinkers, and problem-solvers who believe that the next generation of space operations will be powered by better data and smarter software.

Slingshot Aerospace is looking for a Senior Finance Manager to support the continued growth of our international business. In this role, you will directly support the General Manager of Slingshot International and be responsible for the daily finance and business operations.

• Ensure financial compliance with company policies, international regulations, and reporting standards.
• Collaborate with the broader finance team to align reporting, controls, and processes.
• Provide financial insights and recommendations to support growth and decision-making.
• Help establish scalable financial processes and reporting in the first 3–6 months.
