Linux Engineer – Blockchain Project in Sydney

Global Blockchain Project – OnSite in Sydney – Relocation cost covered and VISAs – $400 to $800k First Year Package

What you’ll do:

• You will design, build, and maintain a highly reliable and performant Linux-based infrastructure supporting blockchain initiatives for a leading proprietary trading firm.
• You will engineer validator environments and distributed systems with a focus on low-latency performance, security, and scalability.
• You will take ownership of Linux systems across bare-metal and cloud deployments, ensuring high availability of validators, RPC nodes, and related services.
• You will enhance observability and reliability by developing monitoring, alerting, and diagnostic systems such as Prometheus and Alertmanager tailored for HFT-grade blockchain infrastructure.
• You will harden and secure infrastructure, including server security, key management, intrusion detection, and best practices for mission-critical environments.
• You will work alongside software engineers and researchers on cutting-edge technologies such as consensus algorithms, distributed systems, and cryptography to support complex workloads.
• You will contribute to cross-functional initiatives and external collaborations that directly support the firm’s trading operations.
• You will support a globally distributed team, ensuring near-zero downtime and operational excellence.
• You will continuously evaluate and integrate emerging technologies in Linux systems and the blockchain ecosystem.

Skills you’ll need:

• You will need deep expertise in Linux systems engineering, including kernel-level understanding, performance tuning, and troubleshooting.
• You will need experience building and supporting mission-critical infrastructure in latency-sensitive or trading environments.
• You will need a strong background in container orchestration and automation with tools such as Kubernetes, Terraform, Ansible, and Salt.
• You will need knowledge of networking fundamentals, including low-latency networking, routing, firewalls, and load balancing, with experience across both bare-metal and cloud platforms.
• You will need strong monitoring and observability skills, including building robust alerting systems.
• You will need proficiency in Bash scripting and at least one programming language, with Python, Golang, or Rust preferred.
• You will need the ability to reason about security and reliability at scale, with experience implementing hardened infrastructure.
• You will need a proven track record of building and maintaining complex distributed systems in production.
• You will benefit from prior exposure to blockchain or distributed ledger technology, although a passion for systems engineering and an eagerness to learn is most important.
• You will need reliable and predictable availability as well as a collaborative, hands-on approach.
