Founding Backend Engineer

About the Role

We’re looking for a Founding Backend Engineer to own the infrastructure that powers our real-time, interactive platform. You’ll design and run the systems that handle concurrency, low-latency streaming, user sessions, and deployments — building a scalable backbone for millions of interactions.

This is a flexible backend role: you’ll be comfortable moving across infrastructure layers, from databases and auth to streaming pipelines and core services, using the best tool for the job.

• Build scalable backend services for real-time, interactive experiences
• Design infrastructure for concurrency, low-latency streaming, and user sessions
• Manage user authentication, databases, and secure account systems
• Set up deployment pipelines, monitoring, and auto-scaling workflows
• Optimize for reliability, performance, and cost efficiency across cloud infrastructure
• Work with a mix of backend technologies (including Rust, Python, Node, etc.)
• Handle outages and scaling challenges pragmatically in production

• Have 4–7+ years of backend or infrastructure engineering experience
• Are fluent with cloud platforms and modern Dev Ops practices
• Have experience with real-time systems, streaming, or multiplayer backends
• Are comfortable working in multiple languages (Rust, Python, Node, or similar)
• Have worked with databases, auth, and distributed infrastructure
• Have experience with CI/CD pipelines, monorepos, and auto-deploy setups
• Care about performance, reliability, and scaling under unpredictable loads
• Enjoy solving infrastructure problems in a fast-moving environment

• You’ll be one of the first 5 team members
• You’ll work directly with the founders (MIT backgrounds, bias to action)
• We just raised a sizeable seed round and are backed by top investors
• You’ll own the infrastructure layer that makes real-time AI possible
• We’re building an entertainment product and want to have fun doing it
• You’ll help shape a platform designed for scale from day one
