Linux Engineer | Blockchain Infrastructure

Sydney CBD or Singapore-based - relocation and sponsorship available

5 Days a week in the office

Compensation: Base Plus Discretionary Bonus - No caps

*You'll need to be an expert in low-level optimisation; this is not a Linux admin role.

What you’ll do:

You will design, build, and maintain a highly reliable, high-performance Linux-based infrastructure to support 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 picosecond-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, including 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 the ability to build 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; however, a passion for systems engineering and an eagerness to learn are more important.

You will need reliable, predictable availability, as well as a collaborative, hands-on approach.
