Full Job Description
About the Role:

You'll work at the intersection of applied AI and large-scale platform engineering. Your focus will be on building and owning the core infrastructure, platforms, and toolchains that power our AI-driven generation tools. Our current engineering focus spans:
  • Architect and automate self-serve developer platforms: build pipelines for LLM-powered game generation, asset integration, and production-ready toolchains.
  • Design integrations across 3D engines, iOS/mobile, and cloud systems to speed up iteration and deployment.
  • Instrument automated testing and feedback systems that learn from both self-play and user behavior, accelerating bug detection and product polish.
  • Own new platform features end-to-end -from design to production, ensuring reliability, scalability, and developer usability.
  • Quickly assess and refine Roam's existing architecture, enforce clear service contracts, and eliminate deployment friction in your first week.

We're looking for engineers who have:
  • Scaled AWS (Lambda, SQS, S3, EC2, IAM, DynamoDB), and multiplier backend infra.
  • Deep fluency in sql, nosql, python.
  • Significant experience in software engineering and in applied AI.
  • Comfort with Vector DBs (Pinecone, OpenSearch) and semantic search systems.
  • 1+ year full time experience at a hypergrowth startup.

Strong candidates may also have:
  • Training and finetuning diffusion and language models
  • Work in research and robotics
  • Experience with Game Development, 3D engines / Shaderlab

Compensation:
  • Base salary of $180,000 - $400,000, and 0.25% - 1% equity.
  • Free housing, food, and transportation.
  • Visa Sponsorship & relocation support.


Growth Opportunity

You'll join a mission-driven team working at the frontier of AI world generation. We're HQ'd in SF and currently work 7 days a week. In this role, you'll have the opportunity to:
  • Own Roam's infrastructure, devops and training setups.
  • Define new benchmarks for fun, retention, and interactive intelligence in 3D worlds using behavioral data across thousands of environments.
  • Ship alongside a team that has already built products for 13M+ users, with 1000+ large creators ready to deploy our technology.


If you're excited to move fast, build at the edge of what's possible, and help define how AI inhabits 3D worlds, let's talk.
