RF Systems Engineer

Loftorbital - Toulouse - Global - Construction & Infrastructure

Wanna join the adventure?

Loft Orbital is making space simple. We build and operate reliable, shareable satellites that give customers a faster, simpler path to orbit. By combining flight-proven spacecraft platforms with our own hardware and software, we make it easier to deploy missions in space.

As an RF Systems Engineer, you'll contribute to the design, development, and integration of communication systems across our satellite connectivity and next-generation RF payload programs. You'll work on RF system architecture, signal processing algorithms, and performance analysis, collaborating closely with FPGA, embedded software, systems, and hardware engineers to develop and integrate complex RF technologies.

This role is ideal for an engineer who enjoys working at the intersection of RF hardware and signal processing, solving challenging technical problems, and seeing their work go from initial design to in-orbit operation.


About this Role:
  • Contribute to the design and development of RF systems for satellite connectivity and payload applications, including architecture, requirements, and technical trade-offs.
  • Perform RF link budget analysis and evaluate subsystem performance across S-band, X-band, and inter-satellite link (ISL) applications.
  • Develop and optimize signal processing algorithms for RF payloads using MATLAB and related simulation tools.
  • Support RF payload development across the signal chain, from antennas and RF frontends to ADCs and SDR systems, including signal detection and geolocation.
  • Collaborate with FPGA, embedded software, and systems teams to translate RF requirements into implementable solutions and integrate signal processing algorith
