We are seeking a highly specialised HFT System and Network Engineer to join our trading infrastructure team. In this role, you will bridge the gap between our cutting‑edge AWS environments and physical colocation facilities. You will be responsible for the end‑to‑end optimisation of our global trading stack: minimising tail latency, optimising cross‑region connectivity, and automating the deployment of performance‑tuned “bare metal” and cloud instances.
Jobs to be Done
- Low‑latency Infrastructure Build: Architect and deploy HFT‑grade stacks, focusing on low‑latency connectivity to crypto exchanges and internal networking alike.
- Hybrid Cloud Optimisation: Manage the interplay between AWS servers and physical hardware in traditional colocation centres.
- System Performance Tuning: Implement deep‑level Linux kernel optimisations to minimise jitter and improve performance.
- Network Automation: Develop “Zero‑Touch” deployment pipelines using Terraform and Ansible to ensure infrastructure is reproducible and error‑free.
- Precision Monitoring: Instrument the network for microsecond‑level visibility, tracking packet loss, jitter, and retransmissions.
- Connectivity Management: Coordinate with exchanges and providers to manage cross‑connects, LOAs, and high‑speed transit lines.
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.
- Execution‑Driven: A clear, concise communicator who thrives in high‑pressure environments and takes ownership of the entire infra lifecycle.
