This description is a summary of our understanding of the job description. Click on 'Apply' button to find out more. Role Description You’ll join the team building Vyry, a mobile app that helps students meet in real life through short, coordinated campus quests. Right now, our focus is Quest Participation optimization: keeping peers on the quest screen while they coordinate via chat, voice, and AR Meet, without state glitches, drop-offs, or broken realtime behavior. This role is not about “building chatbots.” It’s about shipping realtime intelligence inside a live social product, where state correctness, latency, and user trust matter. What You’ll Work On - Designing context-aware quest logic (physical + social + temporal signals) - Detecting stall or drop-off conditions during coordination - Suggesting structured micro-actions that increase completion probability - Instrumenting evaluation loops tied to measurable behavioral outcomes - Shipping production-facing components You will operate on top of existing real-time systems — not rebuild infrastructure. Qualifications - A strong computer science or engineering student - Someone who has shipped real systems (GitHub required) - Comfortable reasoning about state transitions and edge cases - Curious about AI systems beyond simple prompt usage - Able to move from idea → working prototype quickly Requirements - Design a simple state-aware workflow - Think through failure modes - Explain tradeoffs (latency, cost, reliability) - Tie technical decisions to measurable outcomes - Bonus if you’ve built: - Agentic workflows - Multiplayer or event-driven systems - Evaluation pipelines for AI systems - Side projects used by real users How We Evaluate - Systems clarity (state + failure thinking) - Execution speed - Ownership - Depth over pedigree Benefits - Work on a Real Behavioral Problem. You won’t optimize clicks. You’ll design systems that influence real-world human coordination and identity formation. - This is AI applied to physical behavior — not interface optimization. - Ship Systems That Matter. Your work will tie directly to: - IRL Quest Completion Rate - D30 Retention - Learn From Operators Who’ve Built at Scale. You’ll work with the founding team, engineers and researchers from: - Founder DNA - Roblox (LLM + search systems) - Niantic (AR + real-world coordination) - Stanford / Berkeley / MIT / CMU - Operate in a High-Bar, Low-Bureaucracy Environment. We value: - Meritocracy over pedigree - Shipped systems over slide decks - Clear thinking over buzzwords - Build a Rare Skill Set. You’ll gain experience at the intersection of: - Agentic AI systems - Real-time coordination - Behavioral metrics - Spatial computing Compensation & Structure - Competitive compensation - Flexible remote structure - FT 3 months or PT 6 months - High ownership, small team Apply - CV - GitHub - A concise architecture walkthrough of one system you built - One failure you debugged (what broke, why, what changed) - A short note (≤300 words) on how you’d increase IRL Quest Completion by 15% We review for depth, not buzzwords.
