About The Position

We are seeking a Sr. Embedded Software Developer to drive the technical direction, architecture, and implementation of our LynxOS-178 RTOS and hypervisor features for our Mosaic platform per customer needs. This role requires deep expertise in driver development, virtualization across x86 and ARM architectures, as well as the ability to influence product roadmaps, guide cross-functional teams, and tackle the most complex technical challenges. You will be instrumental in ensuring our LynxOS-178 RTOS and hypervisor solutions meet the demanding performance, scalability, and safety-critical requirements of aerospace, defense, industrial, and edge markets.

Requirements

5-8+ years of experience developing systems-level software, including virtualization, OS kernels, or hypervisors for x86/ARM.
Experience on at least one RTOS (e.g., LynxOS-178, VxWorks, QNX, FreeRTOS) or Linux kernel space development.
Experience with performance analysis (perf, ftrace) and packet capture (tcpdump/Wireshark) tools.
Strong debugging skills in low-level system software and ability to resolve complex performance and reliability issues.
Strong communication skills and a demonstrated ability to manage multiple projects simultaneously.
Expert proficiency in C/C++ with working knowledge of x86/ARM assembly for low-level tasks.
Deep understanding of x86 and ARM architectures, including virtualization extensions.
Proven track record architecting and implementing hypervisor technologies (e.g., KVM, Xen, VMware, Hyper-V) at the source code level.
Familiarity with modern development workflows (CI/CD, DevSecOps) as applied to low-level systems software.
