Think Roblox meets Netflix. Fans on Riffio are not just viewers, they become players. Using our in-house engine, they remix storylines, voice characters with AI, and build their own “interactive shows” inside the app. We’re scaling fast — millions of plays, AAA IP partnerships, and a growing creator community redefining what storytelling looks like for the Creation Generations (Gen Alpha + Gen Z). Now we’re looking for a Senior Rust Engineer to help us architect, optimize, and scale the real-time systems that make all this magic happen. The Role You’ll join our core engineering team responsible for Riffio’s backend platform and interactive engine, working closely with our product teams. You’ll design APIs, optimize performance, and make creative tech decisions that directly shape the future of interactive storytelling. This isn’t just another backend job, it’s about building a world-class content engine that merges AI, fiction, and fan-driven gameplay in real time. What You’ll Do: Core Platform Development Design, build, and maintain core backend services in Rust for high-performance, low-latency processing. Architect scalable microservices that handle millions of user interactions and AI-generated content requests. Build robust APIs and internal SDKs used by mobile, web, and Unity clients. Engine Infrastructure Develop and optimize the Riffio Interactive Engine that executes branching stories, user inputs, and image/audio/video generation. Collaborate with AI and game teams to integrate real-time voice, vector search, and media streaming. Systems & Reliability Ensure uptime, scalability, and observability across all platform services. Build automated testing, CI/CD pipelines, and telemetry. Work with Supabase, MongoDB, and AWS ECS/S3 infrastructure to deliver fast and reliable data flow. Collaboration & Innovation Partner with front-end teams to define API contracts and improve developer experience. Collaborate with content and AI teams to prototype new features and launch new shows What You Bring 5+ years of software engineering experience (2+ years hands-on with Rust). Strong foundation in systems programming, concurrency, and async architecture. Experience designing scalable, distributed services (microservices, messaging, caching). Familiarity with Postgres/Supabase, MongoDB, AWS, and CI/CD pipelines. Understanding of APIs, WebSockets, and real-time event systems. Bonus: experience with audio/video pipelines, AI inference, or game engine integrations (Unity, Unreal, Godot). Bonus: previous experience at a creative or entertainment platform (gaming, media, UGC, or social). You Might Be a Fit If… You love building tools that empower creators. You’ve shipped complex systems in Rust and know what good performance looks like. You thrive in fast, high-ownership startup environments. You want to shape the tech foundation for a platform that could redefine storytelling. Compensation Competitive salary ($125k-$150k) + equity package
