- 5+ years architecting cloud-native applications on AWS
- Strong experience with data modeling, distributed data systems, and ORMs
- Proficiency in one or more modern languages: TypeScript, Python, Rust, Go
- Full-stack familiarity, including modern frontend frameworks
- Ability to lead technical conversations and influence architectural direction
- Comfortable working in a fast-moving, evolving product environment

- Hybrid working in Dublin with a deeply collaborative engineering culture
