• Provide hands-on leadership in the implementation of ARLO’s domain-driven, microservice-based architecture, writing high-quality, production-grade code in .NET Core.

• Establish and champion domain boundaries and patterns using Domain-Driven Design (DDD), and partner closely with the Solution Architect to implement the ARLO reference architecture.

• Lead by example through active participation in sprints, pairing with developers, and committing to critical codebases, while supporting performance optimisation, service resiliency, and secure coding practices.

• Review and interpret business requirements in collaboration with Product Owners, translating epics and stories into detailed technical designs and engineering tasks.
