• Lead technical decisions across workflows, integrations, and AI/LLM-powered systems
• Build reliable, event-driven architectures with strong focus on scalability and performance
• Improve observability, testing, CI/CD, release quality, and secure engineering practices
• Use AI coding tools such as Claude Code, Codex, or similar tooling in your daily workflow
• Solve complex technical challenges across different parts of the system, beyond your direct area of ownership
• Collaborate closely with Product, Engineering, and Customer Success to translate ideas into robust solutions
• Coach teammates through code reviews, technical discussions, and sharing architectural best practices

• You have 5+ years of experience as a software engineer
• You’re strong in software fundamentals: clean code, testing, CI/CD, maintainability, and system design
• You take ownership, move fast in complex systems, and make pragmatic technical decisions with a holistic mindset
• You communicate clearly, collaborate well across teams, and can confidently explain technical trade-offs
• You enjoy solving complex problems, mentoring others, and contributing to engineering best practices
• You have hands-on experience with AI-assisted development tools such as Claude Code, Codex, or similar tooling
• You’re excited about how AI is transforming software engineering and actively explore better ways to build, test, and ship software
• Experience with LLMs in production, workflow automation, integrations, martech, or SEO tooling is a plus
• Available full-time at our office at the High Tech Campus in Eindhoven

• A key engineering role in a fast-growing AI SaaS company
• High ownership and direct influence on architecture and engineering culture
• Freedom to experiment with modern tooling and technologies
• Real technical challenges with direct product impact
• A competitive salary
• 23 vacation days
• Transportation allowance
• An energetic startup environment with team outings and shared wins
