Salary: Competitive
Head of IT & Infrastructure | Sydney
Take complete ownership of IT and infrastructure for a fast-growing technology business. We're partnering with a rapidly scaling technology company where software, hardware and advanced engineering come together.
This is an opportunity for a hands-on infrastructure leader to take full ownership of the systems keeping the entire operation running, from complex networking, cloud and security through to the specialist infrastructure supporting engineering and production.
The business is growing quickly and needs someone who can bring structure, improve reliability and build an infrastructure environment capable of supporting that growth.
You'll have the autonomy to make technical decisions, shape the long-term infrastructure roadmap and build out the IT function as the business expands.
We're looking for someone with broad technical capability who has experience taking ownership of infrastructure across a business, rather than specialising in just one area.
What You'll Be Working On- Networking: Own the design and operation of the network environment, including switching, routing, VLANs, firewalls, VPNs and network segmentation.
- Infrastructure: Manage Linux and Windows environments, servers, virtualisation, storage, backups and disaster recovery.
- Cloud: Support and improve AWS, DigitalOcean and on-premise infrastructure, with a focus on reliability, security and automation.
- Identity & Endpoints: Manage Microsoft Entra ID, Active Directory, SSO, MFA, device management and access controls.
- Security: Implement practical security controls, improve infrastructure security and support compliance requirements.
- Engineering Systems: Maintain the infrastructure supporting technical teams, including compute resources, CI environments, storage and specialist equipment.
- Strategy & Ownership: Take responsibility for infrastructure planning, vendors, budgets, documentation and scaling the IT function.
The key things we're looking for:- Excellent networking fundamentals, including hands-on experience configuring switches, routing, firewalls, VLANs and troubleshooting network issues.
- Broad systems administration experience across Linux, Windows, virtualisation and storage.
- Strong Microsoft identity experience, including Entra ID, Active Directory and hybrid environments.
- Experience managing cloud infrastructure, ideally AWS, alongside on-premise systems.
- Scripting and infrastructure automation experience.
- Good security fundamentals across identity, access, endpoints and infrastructure.
- Experience working in a growing business where you've built, improved or taken ownership of systems yourself.
- The ability to move between hands-on technical work, problem-solving and longer-term infrastructure planning.
Experience supporting engineering teams, specialist technical environments or complex on-premise infrastructure would be particularly valuable.
Kubernetes, manufacturing systems and formal security compliance experience would also be useful, but aren't essential.
Why Consider This Opportunity?- Genuine ownership: Take responsibility for how the entire IT and infrastructure environment operates and evolves.
- Build and improve: Design new solutions, modernise existing systems and introduce better ways of working.
- Technical variety: Work across networking, cloud, infrastructure, security and specialist systems rather than being limited to one technology.
- Autonomy: Make decisions, solve problems and shape the future infrastructure environment.
- Growth: Join a scaling business with the opportunity to build and lead a team as the company expands.
- Equity: Competitive base salary plus company equity.
