Job Title: Sr. Software Engineer – Networking/RTOS

Location: Remote, preference for in or near the Dallas/Fort Worth area

Pay Range: $120,000 – $160,000, bonus eligible

Who we are: Lynx delivers modular, open standards-based software solutions that redefine the economics of developing, deploying, and maintaining high assurance, mission critical edge platforms. These secure edge computing solutions are designed to drive innovation and operational excellence in today’s most demanding environments. From advancing aerospace and defense capabilities to transforming commercial and industrial systems, Lynx collaborates across a wide range of industries, including automotive, medical, and critical infrastructure, to deliver tailored, high assurance solutions aligned with specific mission and operational requirements. Our key products and services are: 

• LYNX Mosaic: A software platform that can include a LYNX safety-critical real-time operating system. MOSAI.ic's modular design provides robust support for multicore processing. It allows different operating systems and applications of different criticality levels to be run on separate cores for improved performance, reliability, and security.
• CoreSuite 2.0: A suite of graphics libraries and tools that enable GPU hardware acceleration for both graphics and "GPU Compute", supporting applications such as machine learning and AI processing in edge devices.
• MOSA.ic.SCA and Vigiles, tools that provide Software Bill of Materials (SBOM) and Common Vulnerabilities Exposure (CVE) management for embedded Linux-based and other applications.
• Software development services for high-reliability applications that can include initial setup of a "DevSecOps" development environment, software application development, and long-term product lifecycle management. 

The Role: The candidate will work as part of a team to design, implement, test, and document network software in our LynxOS-178 RTOS. The candidate will help to implement the software with a focus on system security, performance, and interoperability.  

Key Responsibilities:

• Architect, design, network protocols and services (e.g., IPv4/IPv6, UDP/TCP, IPsec, TSN (Time-Sensitive Networking) in an embedded environment.
• Develop and maintain software for embedded systems, ensuring real-time performance and reliability. 
• Conduct thorough network performance analysis and optimization. 
• Collaborate with cross-functional teams to ensure seamless integration with network protocols and application stacks. 
• Troubleshoot and resolve low-level network and software issues, distinguishing hardware from software challenges. 
• Enhance the efficiency, scalability, and stability of networking solutions through innovative development and optimization. 
• Develop application-level BSD/POSIX sockets programming solutions for real-time operating systems and hypervisors. 
• Work on a variety of other RTOS and tools related technologies.
• Supporting the generation and review of certification data.
• Perform additional job duties as assigned.

Requirement

• Must be a US Citizen.

Education & Experience:

• BS/MS in Computer Science/ Electrical Engineering
• 8+ years of relevant experience required.

Proficiency in the following: 

• C Programming and BSD/POSIX sockets programming.
• Experience with networking protocols such as: TCP, UDP, IPv6, IPv4, IPSec and TSN. 
• 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.

• Proven ability to troubleshoot and resolve complex software and networking challenges. 
• Strong communication skills and a demonstrated ability to manage multiple projects simultaneously. 
• Experience with Agile methodologies and tools such as Jira, Confluence, Git and Gerrit. 
• Solid understanding of CI/CD workflows and tools (e.g., Jenkins, Azure DevOps).
