Full Stack Software Engineer (AI-Driven)

At Cleafy, we build software that protects digital businesses and millions of users from fraud and cyber threats. We are looking for a Full Stack Software Engineer with strong technical foundations and a genuine curiosity for AI-powered solutions, ready to design and build scalable products end to end.

Build systems end to end: Work across the full stack—from user-facing experiences to backend services and cloud infrastructure. You’ll contribute to architectural decisions, choose the right tools for each problem, and build systems that are secure, scalable and maintainable over time.

Simplify complex problems: Security and fraud prevention are inherently complex. Your role is to challenge unnecessary complexity, design clean architectures, write readable code, and continuously improve pipelines, processes and developer experience.

Power security products with AI: Collaborate with product teams to identify where AI and data-driven approaches can meaningfully improve detection, decision-making and user experience. You’ll help take ideas from experimentation to production, ensuring solutions are robust, observable and scalable.

Own what you build: You’ll have autonomy and responsibility across the full lifecycle of your work: from ideation and design to implementation, testing, deployment and evolution in production. You’ll see your software protecting real customers at scale.
