Front-End Software Engineer II

Inversion builds advanced reentry systems to deliver next-generation capabilities from space.
 
Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach.
 
Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds.
 
Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics.

As a Front-end Engineer at Inversion, you will work as part of the simulation team to design, develop, and maintain the user interface/user experience (UI/UX) of the applications that support the simulation and test environments for our flight systems. The simulation team is responsible for ensuring that flight software and flight hardware can be continuously integrated and tested under realistic flight conditions. You will play a key role in the design and development of data visualization, data analysis, and self-service tools that will enable fast, repeatable development and deployment workflows across the engineering stack. Your work will empower Inversion’s engineering teams to iterate rapidly throughout the development life cycle and will strengthen Inversion’s ability to put our products into the hands of our customers with unprecedented speed and agility.

• Design, deploy, and maintain the client-side logic and interface of the applications that support simulation workflows, including high-performance computing (HPC), software-in-the-loop (SIL) testing, and hardware-in-the-loop (HIL) testing
• Develop the front-end tech stack to ensure the performance and maintainability of our applications
• Design and implement a front-end architecture that strikes the right balance between simplicity and flexibility
• Design and develop the user interfaces (UI) that support simulation configuration, management, and monitoring
• Work with back-end engineers to integrate the front-end with the back-end and deliver a smooth user experience (UX)
• Contribute to the design and development of a simulation system capable of automatically provisioning and deploying resources to support simulation workflows

• Experience with tools for building web interfaces (Tailwind CSS, Radix UI, Shadcn UI, etc.)
• Experience with data visualization (graphs, charts, 3D, etc.)
• Familiarity with cloud computing platforms (AWS, GCP, etc.)
• Familiarity with system observability tools (Prometheus, Grafana, etc.)
• Familiarity with containerization (Docker, Docker Compose, etc.)
