Senior AI Engineer - Europe

About the role

ChainGPT is a Web3 and AI company building products at the intersection of blockchain infrastructure, token ecosystems and intelligent automation, and is developing Brain by AIVM, a platform for verifiable, governed enterprise AI. It is looking for a Senior AI Engineer who has fully internalised AI-native development: able to ship at the pace of a small team by directing AI coding agents while keeping the judgment and ownership of a senior or staff-level engineer. The role is remote, with applications accepted through the region closest to the candidate.

Key responsibilities

• Build and ship core product features, systems and infrastructure, turning fast-moving AI-assisted prototypes into reliable, scalable production software.
• Own architecture, security, quality and technical direction across major parts of the product.
• Use tools such as Codex, Claude Code and other AI coding agents to increase engineering output, and direct, evaluate and control agentic development workflows with strong human oversight.
• Help define engineering standards, architecture patterns, review practices and AI-native workflows.
• Work closely with the founders on product, strategy, technical trade-offs and execution.
• Debug complex issues, make high-judgment technical decisions and raise the overall engineering bar.

Required profile

• 8-12+ years of experience building and shipping real production software.
• Strong experience owning systems used by real users, including production incidents, scale, reliability and long-term maintainability.
• AI is central to how you work: daily use of tools such as Codex, Claude Code, Cursor or similar, and the ability to use AI agents while controlling quality, security and architecture.
• Deep software engineering fundamentals across architecture, debugging, system design and code quality.
• Strong security instincts and good judgment about where AI tools excel, where they hallucinate and where human expertise is needed.
• Startup, 0 to 1, founder, first-engineer or early-stage product experience.

Required skills

• Daily use of AI coding tools such as Codex, Claude Code, Cursor or similar.
• Ability to use AI agents to multiply output while maintaining control of quality, security and architecture.

What we offer

• Work alongside the core team on high-impact AI and Web3 products, with remote-first setup and flexible hours focused on outcomes.
• Competitive compensation with performance-based upside where applicable, paid in fiat currency via direct deposit on the first business day of each month.
• Direct collaboration with founders and senior management, with clear accountability and no micromanagement.
• Structured onboarding, the tools you need and room to grow.
• A 90-day probationary period for all new employees.
