About us

ATG (Autonomous Technologies Group) is an AI lab deploying frontier reasoning systems within financial markets. Founders:
Early GPU cloud (9 figure exit). Investors:
Garry Tan / YC + Founder of one of the most successful quant funds, Box Group (Plaid, Ramp, Stripe), top‑tier angels.

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.

• 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

• 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

• 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

We're building a small, elite team. If you're excited by AI, markets, and building from first principles, we’d love to meet you. Work on AI with a massive market opportunity. Early team of repeat founders backed by top investors. High agency, talent‑dense, zero bureaucracy.
