Senior Antenna Engineer

5+ years of professional experience in antenna design, EM simulation, and antenna integration.

Strong R&D experience in RF and antenna systems.

security clearance up to Top Secret.

Deep knowledge of aperture antennas, impedance matching, Smith chart usage, polarization, bandwidth, and RF front-end interactions.

Proficiency with antenna modeling and electromagnetic simulation tools such as HFSS, CST, FEKO, or similar.

Experience with antenna prototyping methods and fabrication approaches.

As a Senior Antenna Engineer, you will lead the design, analysis, integration, and validation of antenna systems supporting Inversion’s next-generation re-entry vehicles.

You will work within the Avionics team to develop high-performance antenna solutions for flight and ground applications, owning antenna development from requirements capture and EM simulation through prototyping, installed performance evaluation, and mission-readiness testing.

This role is ideal for an experienced engineer with deep expertise in antenna design and electromagnetic analysis, and with strong judgment in translating system-level communication and vehicle constraints into robust antenna solutions.

You will help develop critical hardware and systems for cutting-edge maneuverable reentry vehicles - advancing one of the most capable reentry vehicle platforms ever developed.

You will be a key member of the Avionics team, reporting directly to the Director of Engineering, Avionics.

Our engineers are responsible for the complete lifecycle of the hardware they create, including design, analysis, prototyping, test, and integration.

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.
