We’re looking for a Senior Unity Engineer to help build the client-side infrastructure of our training platform. This is not just one-off application work. You will build the client foundation that powers VR training simulations today, and additional client targets over time, connecting it to our server according to a defined client-server architecture. The role demands strong application architecture, on-device services, and performance optimization skills.
The Role
This is a hands-on individual contributor role focused on building and evolving key components of our platform’s client-side architecture. You will build client infrastructure against a defined server-client architecture in which the server owns authoritative simulation state and logic, connecting the client to the server per spec and reflecting server-owned behavior faithfully on the device.
Key Responsibilities
- Own and drive key components of the Unity VR client architecture so they generalize across training simulations and, over time, additional client targets, rather than serving a single application.




- Build client-side infrastructure that connects to the server according to defined contracts and reflects server-owned state and behavior on the device.
- Co-design the client-server API with the backend, defining the data contracts.
- Develop tooling that supports content creators and other developers working on the platform.
- Use AI coding assistants as part of day-to-day development, and build and maintain the pipelines and validation that make their output reliable.
- Make pragmatic architectural decisions and manage technical priorities effectively in a fast-paced, ambiguous startup environment.

Requirements
- Demonstrated professional Unity and C# experience, ideally 5+ years, with a track record of shipping complex applications or products.
- A portfolio demonstrating experience architecting and refactoring large-scale Unity projects.
- VR development for Android within the last five years
