Full Job Description
About the Role:

We are looking for an Embedded Software Development Engineer to build and scale - VirtSat (Leo's Virtual Satellite Simulation platform). VirtSat enables developers and pipelines across Leo to create, provision, and test virtual satellites, ground gateways, customer terminals, and TT&C antennas on EC2 bare-metal infrastructure running KVM/QEMU.

As part of role, you will own the Graviton virtualization layer, managing VM lifecycle, LRU boot, subsystem provisioning, and software deployment for every virtual entity in the constellation. You will work at the intersection of cloud infrastructure, embedded Linux, and satellite operations building the platform that every Leo satellite software release is tested on before launch.

Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

* Develop embedded software in Rust, C, C++, or other modern languages for the virtualization and emulation layer

* Write device drivers and system applications for the various satellite systems running on virtual hardware

* Write software to interact with micro-controllers and emulated hardware peripherals (FPGA, HSM, sensors)

* Build and maintain the custom AMI pipeline that pre-configures all satellite dependencies, reducing provisioning time and preventing dependency drift

* Develop and optimize provisioning scripts that deploy satellite software (LEP images, firmware, certificates) onto emulated LRUs via SSM

* Implement plugin framework extensions for new LRU types (satellites, GGMAs, GTMAs, customer terminals) on the Graviton host

* Build network virtualization between VMs - WireGuard tunnels, inter-entity networking, and TT&C link emulation

* Optimize boot-time and provisioning latency for QEMU-based satellite instances

* Debug and resolve issues at the intersection of host OS (Ubuntu/ARM64), guest OS (LEP/Yocto), and QEMU emulation

* Develop fidelity improvements - HSM crypto emulation, EFUSE emulation, CAN bus simulation, and error injection frameworks

* Work closely with other software and hardware teams to support board bring-up and integration testing

BASIC QUALIFICATIONS

- 3+ years of non-internship professional software development experience

- Experience with Linux systems programming (C, Rust, Python, or Bash)

- Experience with virtualization or emulation (KVM, QEMU, Docker, or similar)

- Familiarity with embedded Linux (boot process, systemd, device drivers, or Yocto/Buildroot)

- Experience with shell scripting and system automation

- BS in Computer Science, Electrical Engineering, or equivalent

PREFERRED QUALIFICATIONS

- Experience with ARM64 architecture or Graviton instances
