Sr. Embedded Software Developer

This remote, senior level role at Lynx Software Technologies focuses on guiding the architecture and implementation of the LynxOS-178 RTOS and related hypervisor features for the Mosaic platform. The position emphasizes driver development, virtualization across x86 and ARM, and cross-functional leadership. Salary range is USD 130,000 - 160,000 per year.

Responsibilities

• Design, develop, and maintain embedded software with an emphasis on real-time performance and reliability.
• Integrate, develop, and optimize core hypervisor components with attention to performance, scalability, and security.
• Troubleshoot and resolve complex system-level issues, distinguishing hardware versus software root causes.
• Ensure smooth integration with RTOS, Linux, and mixed-criticality applications within the Mosaic platform.
• Explore emerging technologies in virtualization, isolation, and mixed-criticality systems.
• Mentor engineers across teams to cultivate future technical leaders within the company.

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 (such as LynxOS-178, VxWorks, QNX, FreeRTOS) or Linux kernel space development.
• Experience with performance analysis tools (perf, ftrace) and packet capture tools (tcpdump, Wireshark).
• Strong debugging skills in low-level system software and the ability to resolve complex performance and reliability issues.
• Strong communication skills and the 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.
• Demonstrated leadership, driving technical decisions and mentoring engineers.
• Must be a US Citizen.
• Willingness to travel up to 25% of the time.
