Member of Technical Staff (Backend)

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, BoxGroup (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.

- 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/NoSQL), 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/NoSQL)

- 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., LangChain, LangGraph, 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
