About CoreSpeed

CoreSpeed is building the infrastructure for AI agents.

Our mission

Better Infra, Better AI Agents.

• CoreSpeed PaaS: Platform-as-a-service designed for large-scale agent deployment with second-level container startup, user-level isolation, and high-performance networking.
• Zypher Agent Framework: Open-source agentic AI framework with pluggable components that let developers focus on business logic and ship their agent product fast.
• DeckSpeed: Our showcase vertical agent built on Zypher and deployed on CoreSpeed—an AI presentation assistant that demonstrates the power of our full stack.

Role Overview

We're seeking a Full Stack Software Engineer passionate about AI agents and agent-native infrastructure. You'll work across our entire stack—from CoreSpeed's platform infrastructure to Zypher framework and vertical agent products. This role requires someone who thrives in an AI-agentic development environment using tools like Zypher Code, Cursor and Claude Code.

Responsibilities

• Build and optimize CoreSpeed PaaS components (orchestrator, router, load balancer, gateway)
• Contribute to Zypher Framework core components and vertical agent development
• Develop web interfaces for agent deployment, monitoring, and management
• Build developer tooling and SDKs that abstract infrastructure complexity
• Implement container orchestration, state persistence, and secure sandbox execution

Requirements

• Full stack expertise: Strong proficiency in modern technologies—frontend (React, TypeScript) and backend (Rust, Go, Deno, etc)
• Infrastructure knowledge: Understanding of containerization, orchestration concepts, and cloud platforms
• Systems thinking: Architect scalable, distributed systems that handle dynamic workloads
• Product-minded: Focus on developer experience and making complex infrastructure invisible to users
• Collaborative: Thrive in a remote-first team using GitHub and Discord

Preferred Qualifications

• Strong product ownership: Take end-to-end responsibility for features and drive them to completion
• Experience with LLM APIs, prompt engineering, and context engineering
• Background in distributed systems, observability, and performance optimization
• Contributions to open-source projects or developer tools/frameworks
• Experience with agent evaluation frameworks (GAIA, SWE-bench, etc.)

Why Join CoreSpeed?

• Real infrastructure problems: Build the missing layer that makes agent deployment as easy as deploying web apps
• Open-source impact: Shape Zypher Framework and influence agent development for thousands of developers
• Well-backed: Funded by Baidu Ventures and Monad Ventures
• Competitive equity: Stock options for early team members
• Remote-first: Work from anywhere with a globally distributed team
• High impact: Early-stage opportunity to shape architecture and product direction

Our Tech Stack

• Frontend: React, TypeScript
• Backend: Rust, Go, Deno
• Infrastructure: Docker, Kubernetes, Firecracker
• AI Agents: Zypher Agent Framework, MCP

If you believe AI agents will fundamentally transform how software works, and you want to build the infrastructure that makes this future possible, we want to hear from you.

Apply now and help us build Better Infra for Better AI Agents. 🚀
