ProblemYoung people are more connected online than ever, yet lonelier than any generation before them.\nMost digital platforms are designed for passive consumption on screens, pulling people away from the environments they live in.\nWe are exploring the opposite:technology that brings people together in real-world environments.\nTo do that, software must understand place, not just users and clicks.\nWhat We Are BuildingVyry builds context-aware AI quests that get students to meet IRL.\nThe system turns environments — starting with university campuses — into interactive canvases where students coordinate actions and co-create digital artifacts anchored to real locations.\nWe are in closed beta and measure strong signals:\n\n12k → 175k students reached in 2025\n\n25% of MAUs complete quests\n\npilots show up to 40% reduction in social isolation\n\nThe team combines consumer product, spatial, and game-world expertise, with former talents from: Roblox • Niantic • Ubisoft alongside a research layer that includes: 2 professors + 4 PhDs\nThe company is also part of:Google AI Startup Program and prototyping on Meta’s invite-only Wearables SDK\nWhat You Would Work OnCore product stack includes:\nUnity real-time spatial environment layer\n\npersistent digital artifacts anchored to real-world locations\n\nmulti-user spatial interaction systems\n\nAI-assisted pipelines for generating spatial objects\n\nHard Problems We’re Exploring\nPersistent spatial worlds — artifacts anchored to real places that persist across users, sessions, and devices\n\nMulti-user spatial synchronization — ensuring multiple users see and interact with the same artifact in the same physical location\n\nMobile-first spatial computing — running tracking, rendering, anchors, and networking within phone and wearable hardware constraints\n\nReal-time spatial rendering with AI context — Unity rendering environments in real time while receiving contextual input from large world models and action models\n\nRoleWe are looking for a senior Unity engineer who wants to become a founding technical contributor.\nYou would help:\nshape Unity architecture\n\ndesign spatial persistence systems\n\nbuild multi-user spatial interaction systems\n\nintegrate AI-assisted development workflows\n\ndefine the long-term technical direction of the platform\n\nWe are not looking for someone to simply use Unity.\nWe are looking for someone who wants to help define the architecture of a new spatial computing product category.\nCompensationThis is an equity-first founding role.Compensation is equity-only until our next funding round (target H2 2026).\nYou can join either:\nPart-time, while keeping your current role\n\nFull-time\n\nMany experienced engineers start part-time first while evaluating the opportunity.\nThis role is designed for someone who wants to build a startup without having to start one alone from scratch.\nWho This Is ForEngineers who:\nhave deep Unity experience (typically 8–10+ years)\n\nhave shipped complex real-time systems\n\nenjoy architecting systems rather than just implementing features\n\nare curious about AI integration into interactive environments\n\nThis often resonates with engineers who have spent years inside larger companies and want to build something meaningful with ownership.\nWho This Is NOT ForPlease do not apply if:\nyou are looking for a salaried job today\n\nyou want a freelance contract or short-term gig\n\nyou are bridging time until your next role\n\nThis is a founding role with startup emotions.\nIf InterestedSend:\nGitHub or portfolio\n\nexamples of Unity systems you built\n\nanything you’ve experimented with involving AI\n\nPlease also include short answers to the questions below.\nPS: If you have spent years building complex Unity systems and occasionally think:\n“If I were part of a startup, I would architect it differently.”\nYou are probably the person we are hoping reads this.\nOriginally posted on
