Required Skills and experience:
Low-Latency DNA: Proven experience in HFT or ultra-low latency environments where microseconds matter.
Linux Mastery: Deep knowledge of system internals (CPU pinning, NUMA, kernel bypass) and performance profiling.
Advanced Networking: Expert understanding of BGP, Multicast, and AWS networking.
Automation-First Mindset: Proficiency in Python/Bash and Infrastructure as Code (Terraform) to manage complex global deployments.
Hardware Savvy: Comfort working with high-performance NICs, low-latency switches (Arista/Cisco), and physical data centre requirements.
