ph3The Company: /h3 pWe are a US‑founded early stage start‑up with an RD team located in Europe. Our mission is to make learning accessible, relevant, and individualized to keep up with the changing world. /p pWe 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. /p pWe 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. /p h3The Role: /h3 pThis 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. /p h3Key Responsibilities: /h3 ul liOwn 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. /li liBuild client‑side infrastructure that connects to the server according to defined contracts and reflects server‑owned state and behavior on the device. /li liCo‑design the client‑server API with the backend, defining the data contracts.



/li liDevelop tooling that supports content creators and other developers working on the platform. /li liUse AI coding assistants as part of day‑to‑day development, and build and maintain the pipelines and validation that make their output reliable. /li liMake pragmatic architectural decisions and manage technical priorities effectively in a fast‑paced, ambiguous startup environment. /li /ul h3Requirements: /h3 ul liDemonstrated professional Unity and C# experience, ideally 5+ years, with a track record of shipping complex applications or products. /li liA portfolio demonstrating experience architecting and refactoring large‑scale Unity projects. /li liDirect experience building for VR, in particular Meta Quest. /li liA track record of building generic, reusable infrastructure and frameworks, not just one‑off features. /li liComfort working within a defined client‑server architecture and with established API contracts. /li liA proactive and adaptable mindset suited for the dynamic and evolving environment of an early‑stage startup. /li liExcellent communication and collaboration skills in English, with experience working effectively in a remote, culturally diverse team. /li liA genuine interest in using technology to enhance learning and education. /li /ul h3Nice To Have: /h3 ul liExperience targeting additional client platforms such as WebGL. /li liExperience with data‑driven or reactive component systems. /li /ul h3What We Offer: /h3 ul liA high‑ownership role with direct influence on product direction, architecture, and user experience, and on company culture. /li liA senior opportunity to build a platform from the ground up and contribute to its growth and commercialization. /li liThe flexibility of a fully remote position, with working hours adaptable across European time zones rather than tied to US hours. /li /ul /p #J-18808-Ljbffr
