Job summary

ChainGPT is hiring a Senior AI Engineer to ship at the pace of a small team by directing AI coding agents while maintaining strong human judgment and ownership of core product areas. You will work directly with the founders and senior team, shaping product decisions at an early stage.

We seek an engineer who can move from prototype to production quickly, define robust AI-native workflows, and uphold security and reliability as the product scales in a remote, global setting.

Qualifications

• 8-12+ years of experience building and shipping production software.
• Experience owning production systems including incidents, scale, reliability, and long-term maintainability.
• 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.
• A strong ownership mindset: you run toward responsibility, ambiguity, and hard technical problems.
• Startup, 0→1, founder, first-engineer, or early-stage product experience.

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.
