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 our People & Culture Administrator, you’ll play a key role in shaping our employee experience — supporting our people at every stage of their journey, from onboarding through to ongoing development.
This is a hands-on entry level role that would suit a student or recent Graduate. You will keep the engine running behind our people operations and own the administration that holds the P&C function together — HRIS and employment documentation, onboarding, training coordination, talent attraction, and accurate HR reporting. It suits someone who’s organised, detail-oriented, and genuinely enjoys making things work well in an environment where the pace is high and no two weeks are the same.
What you’ll be doing
Responsibilities include:
- Maintain accurate, confidential employee records in the HRIS.
- Support the employee lifecycle by preparing employment documentation, tracking probation, supporting our Employee Share Scheme administration, and offboarding.
- Manage the P&C team inboxes and respond to routine queries from employees and managers.
- Run monthly HR reports and complete compliance audits.
- Support talent attraction — prepare position descriptions, post job ads, manage the ATS, talent pools / pipelines and coordinate pre-employment checks.
- Support delivery of a connected onboarding experience — from preboarding through induction, system access, and first-day setup.
- Coordinate training & development logistics — bookings, comms, attendance — and maintain the company training register.
- Shape the team experience — support employee recognition incentives, coordinate merchandise, support internal team events and internal communications.
- Contribute to P&C continuous improvement — policy updates, SharePoint upkeep, and process documentation.
Life at Hypersonix

- Take ownership of your work and keep things moving, even when the picture isn’t complete
- Care about doing things well and getting them done — and learn to balance both
- Stay calm and constructive when priorities shift.
What You’ll Bring
To hit the ground running in this role, you’ll need:
- Qualification in human resource management or a related field (or studying toward).
- Proficiency with Microsoft 365 including Excel, Word, SharePoint, and Teams.
- Clear, professional communicator who can engage credibly with employees and leaders at all levels.
- Highly organised with the ability to manage competing priorities, meet deadlines, and self-direct in ambiguous situations.
- Strong attention to detail and a high standard of accuracy across all written documentation.
- Discreet and trustworthy, with a mature approach to handling confidential information.
- Ability to obtain any applicable security clearance or background checks.
- Right to live and work in Australia.
Bonus points for:
- Prior experience in an HR, administration, or professional services environment
- Experience with an HRIS or ATS platform.
- Experience working in a fast-paced, high-growth, or startup environment.
- Experience in aerospace, defence, advanced manufacturing, or a similarly technical environment
