This is for someone who can ship at the pace of a small team by directing AI coding agents, while still bringing the judgment, fundamentals, and technical ownership of a senior/staff-level engineer. You understand where AI tools are powerful, where they fail, and when human judgment needs to lead. You can move quickly from prototype to production, own complex technical decisions, and help shape the product at a very early stage. You'll work directly alongside the founders and senior team, with meaningful ownership over core parts of the product. What You'll Do * 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, At ChainGPT, we value Trust, Effective Speed, Innovation, and Growth. As our Senior AI Engineer, you will embody these core values and have the opportunity to contribute to our culture and help drive our success.
