About the role:

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. This is a high-impact role where your optimisations directly translate to our competitive edge in execution speed across both CeFi and DeFi exchanges.

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 centers.
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.

What we offer:

An amazing global culture, who are ambitious, innovative and fun while working with the highest levels of honesty and integrity.
Two discretionary bonus awards a year.
A range of benefits in line with local market practice.
Regular fun events and activities, as well as Social Impact volunteering days.
