Builds and automates RF test benches and test infrastructure in Python and C++ to characterize custom satellite RF payloads for SpaceX's Starshield national-security program. Works closely with RF, DSP, FPGA, and hardware engineers and creates electromagnetic simulation models of RF hardware.
New Graduate Engineer, Software (Starfall)
New-grad software engineer on SpaceX's Starfall team designing and implementing software and firmware for next-generation avionics: writing C/C++ for processors and microcontrollers, bringing up and validating space-flight devices, analyzing bugs, and supporting launch operations. Open to class of 2026/2027 grads; no aerospace experience required.
Security Engineer (OT)
SpaceX is hiring a Security Engineer (OT) to secure the operational technology networks behind launch, vehicle, test, and production. The role is hands-on: writing security software (Python/Go/C#/C++/Rust), automating on-prem and data center networking, implementing OT network segmentation, and producing security architectures — fully onsite at Cape Canaveral, FL.
RF Silicon Software Engineer (RFIC Engineering)
SpaceX is hiring an RF Silicon Software Engineer in Redmond, WA to bring new custom RF chips to life for Starlink satellites, ground infrastructure, and user terminals. Day to day: powering up first silicon, writing low-level C/C++/Python driver libraries, building hardware-in-the-loop test platforms, and supporting flight software integration.
FPGA/ASIC Design Engineer (Silicon Engineering)
Designs next-generation ASICs and FPGAs for SpaceX's Starlink satellite and ground network, taking chips from architecture through RTL design in SystemVerilog/Verilog, optimization, implementation, and lab bring-up/validation. Core skills: RTL design, SoC integration, EDA tools, and scripting with Python/C++.
Sr. RF Silicon Software Engineer (RFIC Engineering)
Brings up SpaceX's custom RF silicon for Starlink satellites, ground gateways, and user terminals: writes low-level C/C++/Python driver libraries, builds hardware-in-the-loop test platforms with automated regression tests, and supports flight software integration. Works at the hardware/embedded software boundary of a high-performance wireless comms system.
Sr. Software Engineer, AI Infrastructure (Starshield)
