- Experience with memory managed high performance ARM Cortex-A or X86 architectures and SoCs (NXP, Freescale, Intel, AMD, Xilinx, Altera, …).
- Experience with the Linux kernel itself or the kernel of any other operating system with strictly isolated kernel and user spaces.
- Proven success with root-cause investigation of bugs related to operating systems, hypervisors, or hardware-level drivers.
- Proficiency in the C programming language
- Proficiency with Git at a command line level
- Ability to track and work on multiple projects simultaneously while meeting schedules.
- Demonstrated experience of leading software projects while providing technical inputs to unblock supporting teams.
- Keen sense of urgency and drive for results.

◦ Must be able to read integrated circuit data sheets and understand register configuration procedures.
◦ Must understand interrupts and how to appropriately use them to our advantage
◦ Must understand when and how to appropriately use DMA to our advantage
- Operating System core kernel development experience
◦ Must have experience with scheduling and timing-related mechanisms and issues in any of the OS kernels as described above
◦ Must have extensive understanding with context switching, preemption, interrupts, timers, and locking mechanisms.
◦ Must have knowledge of Unix-style file-system data structures (inodes, …)
◦ Must have knowledge of page tables and memory management.
◦ Must have cursory knowledge of assembly level bootstrapping in either ARM or X86 instruction sets.

What We Do
For over thirty years, Lynx Software Technologies has helped customers with some of the most demanding, mission critical, system requirements to create, certify, and deploy equipment, above, on and below the surface of the earth.. Lynx for the Internet of Things (IoT): As billions of ‘things’ are connected to the internet, a new paradigm of security is required. Lynx offers real-time military-grade security products to protect the edge, the gateway and cloud devices while protecting any sensitive data as it traverses the IoT. Key Markets: Automotive, Industrial, Factory Automation, Medical and Transportation. Our LYNX MOSA.ic software framework and LynxSecure separation kernel hypervisor provide a secure foundation for this new generation of connected platforms. Lynx for Enterprise Cyber Security: To fight modern day malicious threats, security needs to be built-in rather than implemented as an afterthought. Lynx offers isolation technology that can be implemented in endpoint and cloud deployments to separate and protect critical enterprise infrastructure. This isolation technology separates sensitive information from the key attack points and denies infiltration and exfiltration attempts. Lynx for Aerospace & Defense: Lynx provides certified avionics RTOS solutions based on open standards such as POSIX, ARINC and FACE that allow reusability of certified code and systems. The FAA Reusable Software Component (RSC) has been issued to LynxOS-178. The LynxOS 7.0 RTOS and LynxSecure separation kernel technologies were designed to provide the highest levels of security without compromising performance and real-time determinism.
