Secure OS / RTOS Kernel Engineer

Develop and harden a low-overhead microkernel (seL4-class) for flight-control computers — guaranteeing task isolation, memory safety, and tamper-proof runtime.

Flight-control computers must be predictable and tamper-proof, all the way down to the kernel. You will develop and harden a low-overhead, seL4-class microkernel that guarantees task isolation, memory safety, and a trustworthy boot chain. This is deep systems work — page tables, MPU/MMU, scheduling jitter, secure boot, side channels — where correctness is the whole job and a missed edge case is a real liability in the field.

• OS kernel internals, page tables, microkernel design (seL4, RT_PREEMPT, Xen)
• C, Assembly, and low-level Rust
• MPU/MMU memory protection and secure virtualization
• Formal verification concepts and static analysis

• Harden entrypoints with strict compartment isolation
• Minimize scheduling jitter for predictable control loops
• Embed integrity checks in the secure-boot sequence
• Audit for side-channel vulnerabilities
