The Company:
We are a US-founded early stage start-up with an R&D; team located in Europe. Our mission is to make learning accessible, relevant, and individualized to keep up with the changing world.
We are developing a personalized virtual trainer experience, integrating generative AI and learning engineering to build a VR simulator for immersive hands-on skills training. Our learning engineering approach customizes content and feedback in real-time, directly improving learning outcomes.
We are 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
