Location: Toronto, Ontario Senior Full-Stack Engineer - Interactive Systems & AI Our client is building a new kind of interactive character experience: combining animation, real-time systems, and AI to bring expressive digital characters to life. We’re developing a platform where characters are not just animated, but responsive, programmable, and part of a living system. This is an early-stage effort with a small team, working directly with the founder to explore, prototype, and ship quickly.

What This Role

Is - A high-autonomy role focused on building new interactive systems from scratch - A chance to explore and define how AI + animation + real-time interaction come together - A close partnership with the founder and creative team to shape product direction - An opportunity to make foundational technical decisions early What You’ll Do - Take early concepts and turn them into working interactive systems and product features end-to-end - Build across the stack: modern frontends (React / Next.js), APIs, and backend services - Develop systems that support real-time character interaction, including animation triggers, voice, and behavior - Evaluate and experiment with different technical approaches, including: Live2D pipelines and alternatives

- AI-driven motion / video systems (e.g.,



SeeDance or similar)
- Voice synthesis and real-time voice transformation APIs - Work closely with animators to integrate character assets into interactive systems - Rapidly prototype and test build vs integrate vs buy decisions - Ensure systems are performant, observable, and production-ready as they evolve Must Have Skills - 5+ years of professional experience as a software engineer - Strong full-stack capability (TypeScript/React + Node systems) - Experience building and shipping interactive or real-time systems - Comfort working in ambiguous, fast-moving environments with evolving requirements - Ability to evaluate multiple technical approaches and form clear, opinionated trade-offs - Experience integrating external APIs and stitching systems together quickly - Robust ownership. You can take a concept from idea - prototype - production Nice to Have Skills - Experience working with animation systems (Live2D, Spine, Unity, WebGL, or similar)
- AI media tools (video, motion, or audio generation)
- Voice synthesis, audio processing, or real-time streaming systems - Familiarity with event-driven or real-time architectures (WebSockets, streaming pipelines)
