Investors:
Garry Tan / YC + Founder of one of the most successful quant funds, Box Group (Plaid, Ramp, Stripe), top-tier angels.

About the Role

You'll architect, build, and maintain the distributed systems, APIs, and backend infrastructure that power world-class AI research and deployment. Your work will enable rapid experimentation, robust data flows, and scalable compute. This is a hands-on role for someone who thrives in small, high-agency teams.

Responsibilities

• Design and implement scalable backend services, data pipelines, and APIs
• Build infrastructure for high-throughput, low-latency AI/ML workflows
• Set up and manage databases (SQL/No
  
  SQL), including schema design, replication, indexing, and performance optimization
• Optimize for performance, reliability, and security at every layer
• Implement observability best practices (logging, tracing, monitoring, performance tuning)
• Work closely with research and infra teams to support experimental velocity
• Contribute to core engineering culture, including code reviews and mentorship

Requirements

• 3+ years building distributed systems or high-availability backends (preferably in fast-moving or high-stakes environments)
• Strong proficiency in Python and at least one systems language (e.g., Go, Rust, C++)
• Experience with cloud platforms, containerization, and orchestration (AWS/GCP/Azure, Docker, Kubernetes)
• Database setup, management, and optimization experience (SQL/No
  
  SQL)
• Relentless focus on code quality, correctness, and performance
• Comfortable leveraging modern AI coding tools (Cursor, Claude Code, Codex, etc.) to increase productivity & code output while maintaining high code quality, maintainability, and structure

Bonus – Agentic workflows / applied AI integration

• Experience supporting or integrating agentic AI workflows into backend systems (e.g., Lang Chain, Lang Graph, Semantic Kernel, Haystack, or custom frameworks)
• Familiarity with persistence/checkpointing, streaming pipelines, and vector/knowledge store integrations

Why Join ATG

• Work on AI with a massive market opportunity
• Early team of repeat founders backed by top investors
• High agency, talent dense, zero bureaucracy
