About usATG (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, BoxGroup (Plaid, Ramp, Stripe), top-tier angels.About the RoleYou’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.ResponsibilitiesDesign and implement scalable backend services, data pipelines, and APIsBuild infrastructure for high-throughput, low-latency AI/ML workflowsSet up and manage databases (SQL/NoSQL), including schema design, replication, indexing, and performance optimizationOptimize for performance, reliability, and security at every layerImplement observability best practices (logging, tracing, monitoring, performance tuning)Work closely with research and infra teams to support experimental velocityContribute to core engineering culture, including code reviews and mentorshipRequirements3+ 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/NoSQL)Relentless focus on code quality, correctness, and performanceComfortable leveraging modern AI coding tools (Cursor, Claude Code, Codex, etc.) to increase productivity & code output while maintaining high code quality, maintainability, and structureBonus – Agentic workflows / applied AI integrationExperience supporting or integrating agentic AI workflows into backend systems (e.g., LangChain, LangGraph, Semantic Kernel, Haystack, or custom frameworks)Familiarity with persistence/checkpointing, streaming pipelines, and vector/knowledge store integrationsWhy Join ATGWe'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 opportunityEarly team of repeat founders backed by top investorsHigh agency, talent dense, zero bureaucracy
