Back End Developer

About Empat

Next-generation autonomous AI systems are being built to move far beyond simple interaction — toward software capable of executing complex, real-world operations at scale. Backed by $5.1M from leading founders and venture investors, Empat operates at the intersection of autonomous systems, distributed infrastructure, and applied AI, laying the foundation for truly self-operating digital entities.

At this pivotal stage of growth, we are looking for a Back End Developer to play a central role in architecting and scaling the distributed systems that orchestrate thousands of intelligent AI agents in dynamic, real-world environments. This is an opportunity to shape the backbone of a platform designed for massive scale from day one - where your infrastructure decisions directly impact how autonomous systems perform in production.

Your Responsibilities as a Back End Developer

• Design and build high-performance backend systems that support AI-native product generation at scale
• Develop and maintain Python-based distributed services powering agent workflows
• Build and optimize API-heavy architectures using both Python and Node.js
• Implement robust orchestration layers for managing large numbers of AI agents
• Design and maintain evaluation and feedback loops to continuously improve AI-generated outputs
• Develop asynchronous workflows supporting complex agent lifecycles
• Ensure reliability, fault tolerance, and scalability across distributed components
• Optimize integrations with multiple model and data providers
• Build internal tooling for observability, monitoring, and system health tracking
• Collaborate closely with the Bay Area team within full Scrum ceremonies (daily standups, grooming, sprint planning)
• Take ownership of backend components from design through production

What Empat Expects From You

Core Requirements

• Strong backend engineering experience (Mid+ / Senior level)
• Production experience with Python (required)
• Solid hands-on experience with Node.js for API integrations (required)
• Experience building API-heavy systems
• Understanding of LLM-based systems and AI-native development patterns
• Ability to quickly onboard and operate as a strong individual contributor
• Experience working in fully integrated Scrum teams
• Strong communication skills and proactive ownership mindset
• Availability to work as a fully embedded team member (not part-time across many projects)
• Experience with agent orchestration systems
• Familiarity with LangChain, LangGraph, or similar ecosystems
• Background in distributed systems and asynchronous architectures
• Experience designing evaluation/feedback loops for AI systems
• Experience with PostgreSQL, Redis, or async job queues

Nice to Have

• Experience with multi-agent architectures
• Experience with observability and tracing systems
• Exposure to GPU-enabled or high-throughput infrastructure
