MLabs is building the next generation of autonomous AI employees. The Staff Software Engineer (Backend) will design and build the infrastructure that enables AI employees to operate autonomously, managing complex tasks and processing vast amounts of data.
Responsibilities:
- AI Orchestration: Design and build the high-throughput pipelines that allow our AI to process millions of signals (lead data, engagement metrics, behavioral patterns) and make real-time decisions
- Platform Ownership: Build and scale the infrastructure for email deliverability, inbox management, and complex AI coordination
- End-to-End Execution: We don't separate architecture from implementation. You will design, build, deploy, and monitor your own systems
- Rapid Iteration: Work in a flat engineering org with zero red tape. We ship constantly and move at the speed of a high-growth startup
Requirements:
- 6+ years of backend experience, ideally in a high-growth startup environment where you owned systems from ideation to production
- Deep understanding of distributed systems, database performance, and API design. You should be comfortable building data-intensive services at scale
- You are a '5x engineer' who knows how to leverage modern tools (like Claude Code) to accelerate your output
- Experience with cloud-native infrastructure, including containers, orchestration, CI/CD, and observability
- You have strong opinions on reliability and testing but possess the judgment to know when to move fast to hit market windows
- TypeScript/Node is preferred, but we value strong fundamentals in Python, Go, or similar languages
