• Translating product concepts into technical deliverables alongside design, product, and architecture teams
• Driving modern engineering practices: CI/CD, iterative prototyping, automated testing, and rapid delivery

• 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
• Interest in blockchain or DeFi (advantageous but not required)
• Degree in Computer Science or related field preferred but not mandatory

Why this role?

• Greenfield digital-assets programme inside a global leader
• Full ownership of architecture, engineering direction, and design decisions
• Modern stack, modern ways of working, zero legacy
• Hybrid working in Dublin with a deeply collaborative engineering culture
