About the Role

XRHealth is hiring a Senior Unity Developer to support the delivery of a WorkSafe-funded VR simulation program focused on workforce wellbeing, stress resilience, and conflict-management training.

This role is a hands-on individual contributor position, responsible for building and integrating three VR simulation modules in Unity for standalone Meta Quest headsets. You will work day-to-day with the Australia-based project team, receive technical guidance from XRHealth’s Spain-based platform and XR specialists, and collaborate closely with designers and clinicians.

The project is delivered in an agile R&D environment, with structured review cycles, pilot deployment, and clear milestone-based delivery.

Why XRHealth

XRHealth operates at the intersection of immersive technology, evidence-based care, and real-world impact.

We design and deploy XR solutions used in clinical, workplace, and rehabilitation settings, working closely with clinicians, researchers, and enterprise partners to ensure our technology is effective, safe, and responsible.

For this project, you’ll be part of a WorkSafe-funded initiative with a clearly defined scope, real users, and measurable outcomes — not a speculative product build. The team combines deep experience in VR/XR development, in-house clinical expertise, and a proven delivery model for enterprise and healthcare partners.

If you’re motivated by building immersive technology that is grounded in evidence and used in the real world, XRHealth offers the opportunity to work on projects with genuine impact beyond entertainment.

What You’ll Be Working On

• A standalone Unity-based VR application (Meta Quest)
• Three integrated simulation modules:
  • Depot Simulation – environmental and workflow stress exposure
  • On-Road Stress Exposure – driving scenarios and fatigue management
  • Conflict Management – NPC-based interaction and de-escalation training
• Biometric-informed feedback loops and safety controls
• Session logging and pilot-phase analytics
• Preparing the application for later integration into the XRHealth platform via a standard third-party integration framework

---

Key Responsibilities

Unity & VR Simulation Development (Primary Focus)

• Design and build immersive VR environments and scenarios in Unity
• Implement NPC behaviour, interaction systems, and branching scenario logic
• Develop adaptive in-experience responses (e.g. prompts, pauses) informed by biometric indicators
• Optimise performance, rendering, and memory usage for standalone VR headsets
• Translate design and clinical inputs into stable, high-quality interactive experiences

---

Biometric & Safety Integration

• Integrate real-time biometric inputs (e.g. HRV, voice stress indicators) into Unity workflows
• Implement safety logic including thresholds, pause/exit mechanisms, and escalation handling
• Collaborate with clinical team members to ensure wellbeing and safety requirements are correctly implemented
• Support pilot testing and iterative refinement of biometric responsiveness

---

Supporting Backend & Integration Work

• Implement supporting backend services or integrations for:
  • Session logging and event telemetry
  • Pilot usage analytics and reporting
• Build and consume secure APIs in support of future XRHealth platform integration
• Work within a lightweight AWS-based backend environment as required
• Support cross-module integration and regression testing

This role focuses on application-level integration and does not own enterprise backend architecture or DevOps.

---

Agile R&D Collaboration

• Work in weekly sprint cycles with clear milestones and review points
• Participate in short daily or near-daily syncs with the Spain-based technical team to unblock delivery and maintain alignment
• Collaborate with designers, clinicians, and enterprise stakeholders during structured Q&A and testing cycles
• Produce clear documentation, build notes, and handover materials throughout the project

---

Working Hours & Collaboration Model

• Core working hours are 11:00am – 7:30pm Melbourne time
• This schedule supports:
  • Overlap with the Australia-based team during the day
  • A short daily sync with the Spain-based team in the early evening
• You will report day-to-day to the Australia project lead, with technical support and guidance from the Spain XR/platform team

---

Required Skills & Experience

• 4+ years professional Unity development experience (VR / XR strongly preferred)
• Strong C# and Unity scripting skills
• Experience delivering real-time, simulation-based, or interactive applications
• Demonstrated ability to optimise applications for standalone VR performance
• Experience integrating APIs or backend services into Unity applications
• Familiarity with agile workflows and iterative, milestone-driven delivery

---

Nice to Have

• Experience with:
  • Biometric or physiological data integration
  • NPC behaviour systems or branching dialogue logic
  • Training simulations or safety-critical environments
• Exposure to wellbeing, training, or healthcare-adjacent technology
• Experience working on enterprise or grant-funded R&D projects

Working Style

We’re looking for someone who:

• Enjoys hands-on development and technical problem-solving
• Communicates clearly across distributed, cross-functional teams
• Is comfortable working in research-driven, iterative environments
• Takes ownership of quality, performance, and delivery within a defined scope
