Backend Developer

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, the company 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 Backend Engineer 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 will include:

• 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 we expect from you:

• Core requirements
  • Strong backend engineering experience (Mid+ / Senior level).
  • Production experience with Python (required).
  • Ability to work in the PST time zone until 3 PM.
  • 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.
     

We offer:

• The opportunity to join at a critical inflection point as we scale beyond stealth.
• Ownership over core backend and AI infrastructure components.
• A technically ambitious environment building AI-native systems from the ground up.
• Close collaboration with a highly skilled, fast-moving team.
• Direct impact on systems operating in live production environments.
• A role where technical excellence, autonomy, and long-term thinking are highly valued.
