Job summary

ChainGPT Org, Ltd. is seeking a Senior AI Engineer to lead AI-native development at a fast-moving Web3 and AI company. You will ship production-grade software, guide architectural decisions, and supervise AI-assisted workflows alongside founders.

You’ll work on secure, scalable systems and drive the technical direction across core product areas, with strong ownership and high autonomy in a remote, outcome-focused environment.

Qualifications

• 8–12+ years of experience building and shipping real production software.

• AI is central to how you work: you use tools like Codex, Claude Code, Cursor, or similar AI coding tools daily.
• You know how to use AI agents to multiply your output, while maintaining control over quality, security, and architecture.
• Deep software engineering fundamentals across architecture, debugging, system design, and code quality.
• Strong security instincts and the ability to identify where AI-generated code can introduce risk.
• Excellent judgment around where AI tools excel, where they hallucinate, and where human expertise is required.

Responsibilities

• Build and ship core product features, systems, and infrastructure.
• Turn fast-moving, AI-assisted prototypes into reliable, scalable, production-grade software.
• Own architecture, security, quality, and technical direction across major parts of the product.
• Use tools like Codex, Claude Code, and modern AI coding agents to dramatically increase engineering output.
• Direct, evaluate, and control agentic development workflows while maintaining strong human oversight.
• Help define how the team builds: engineering standards, architecture patterns, review practices, and AI-native workflows.
• Work closely with founders on product, strategy, technical tradeoffs, and execution.
• Debug complex issues, make high-judgment technical decisions, and raise the overall engineering bar.
