Staff Software Engineer

Job description

Job responsibilities

• Define the virtualization safety architecture for a mixed-criticality system, ensuring spatial and temporal isolation between safety-critical and non-safety-critical applications.
• Prototype and evaluate Xen and QNX hypervisors, defining an architecture based on safety, determinism, certifiability, and platform fit.
• Own hypervisor system configuration and integration, implementing creative solutions to overcome platform limitations and gaps in vendor support.
• Architect and implement deterministic inter-VM communication and device virtualization using virtio, shared memory, and PCIe/other device passthrough.
• Plan and execute the analysis and verification needed to demonstrate freedom from interference, deterministic timing, and safe failure behavior in a regulated environment.
• Lead failure modes and effects analysis for the virtualized platform, translating identified failures and technology limitations into design mitigations, fault containment, and defined recovery or degraded behaviors.
• Build platform observability that exposes guest and hypervisor health, resource utilization, latency, jitter, and other relevant system health signals on target hardware

Job requirements

• Demonstrated expertise in designing scalable, high-performance embedded software architectures; advanced proficiency in modern C++ and Python for real-time systems.
• Experience building from 0 to 1: define, build, and evaluate technical prototypes that de-risk platform decisions early, translating open architectural questions into measurable experiments on target hardware.
• Extensive experience in Linux/QNX environments, including kernel modules, resource managers, POSIX applications, and distributed inter-processor communication frameworks.
• Proven expertise with FPGAs, hardware accelerators, PCIe transport/configuration/enumeration concepts, and network stacks; strong ability to root-cause interdependent hardware/software problems.
• Proven track record of leading strategic technical initiatives from concept through completion; ability to work independently and drive results with limited supervision.
• Exceptional communication skills with demonstrated ability to articulate complex technical concepts and influence senior leadership across organizational levels.
• Strong leadership capabilities, including mentoring engineers at all levels, providing technical direction, and potentially supervising activities of others.
• Experience with Xen internals (dom0/domU, PV/HVM/PVH, xl configuration, Xen on ARM or x86) or with hypervisor contributions upstream.
