Job Description

We're building aircraft that fly faster, further, and to space.

Hypersonix is an Australian aerospace engineering and advanced manufacturing company building hydrogen-powered scramjet aircraft. We work at the bleeding edge of hypersonic technology, delivering aircraft that fly faster, reach further, and open new pathways to space - and we're a small,
highly capable team doing work that genuinely matters.

The Opportunity

As an IT Infrastructure Engineer, you’ll be responsible for designing, building, and maintaining Hypersonix’ core IT infrastructure. This includes cloud environments, networking, server
infrastructure, and DevOps tooling. You’ll work closely with the Systems Administrator to ensure our environment is secure, reliable, and aligned to business and compliance objectives.

You’ll be comfortable working at pace and to a high quality, ensuring our infrastructure is deployed and maintained using code-driven, repeatable processes. If you’re an experienced Infrastructure Engineer looking for autonomy to deliver on varied and challenging projects in a scale-up environment, we’d love to hear from you.

What you’ll be doing

• Design, deploy, and maintain cloud and on-premises infrastructure including servers, networking, and storage across Linux and Windows environments.
• Establish and grow our Infrastructure as Code practice using Terraform, building repeatable, version-controlled deployment patterns from a largely greenfield starting point.
• Plan and execute infrastructure lifecycle activities including upgrades, migrations, patching, hardening, and decommissioning, aligned to business growth and compliance requirements.
• Implement and operate monitoring, backup, and disaster recovery to ensure availability, performance, and data resilience.
• Provide Level 3 / engineering-level support for infrastructure incidents, including root cause analysis and permanent resolution.
• Implement security controls aligned to NIST 800-171 r2 and DISP requirements, supporting audits and assessments. Document architectural decisions and operational procedures as you go.
• Support DevOps tooling and CI/CD pipeline infrastructure (GitLab) to enable engineering workflows.

Life at Hypersonix

We're a 60-person company moving fast in one of the most technically demanding fields in aerospace. The pace is fast, the expectations are high and our environment is constantly evolving. Priorities shift, processes are maturing and the path forward isn't always clear; some days you'll need to find it yourself. The people who thrive here are energised by that — not unsettled by it.

You’ll thrive here if you:

• Own problems end to end without waiting for a complete picture
• Hold technical rigour and program pace simultaneously – without sacrificing either
• Lead by bringing people with you, not by working around them
• Stay solutions-focused when the ground shifts.

What you’ll bring

To hit the ground running in this role, you’ll need:

• Bachelor’s degree in information technology or computer science or related field – or
  equivalent industry experience.
• 4+ years’ experience in infrastructure, systems engineering, or DevOps roles.
• Experience with cloud platforms (AWS preferred).
• Experience with firewall and network administration.
• Linux and Windows server administration experience.
• Familiarity with Infrastructure as Code (Terraform preferred).
• Strong troubleshooting and problem-solving skills.
• Excellent documentation and communication skills.
• Australian Citizen with ability to obtain security clearance.

Bonus points for:

• Relevant industry certifications (AWS, networking, or security).
• Experience in defence, aerospace, or regulated industries.
