Solid understanding of distributed systems, microservices, modular monoliths, eventual consistency, and resilience patterns. Practical cloud experience with Azure or AWS, including security, networking, identity and access management, compute, storage, and managed services. Familiarity with cloud development and deployment practices at an associate-certification level, such as AZ-204, AZ-104, AWS Solutions Architect – Associate, or AWS Developer – Associate. Working knowledge of CI/CD pipelines, deployment processes, and application troubleshooting. Experience with relational databases such as SQL Server or PostgreSQL, including data modeling and query optimization. Strong practical experience with AI coding tools such as GitHub Copilot, Cursor, Claude Code, or similar solutions, along with sound judgment about their safe and effective use. A disciplined approach to unit, integration, and end-to-end testing. The ability to learn new domains and technologies quickly, make informed decisions with incomplete information, and deliver value early. Excellent communication and collaboration skills, including the ability to explain technical trade-offs to both technical and non-technical stakeholders. A strong commitment to ownership, continuous improvement, and being a dependable and respectful team member. Preferred qualifications: Experience implementing the Saga pattern through orchestration or choreography for long-running business processes. Familiarity with NServiceBus and the Particular Service Platform, including ServicePulse, ServiceInsight, and ServiceControl, or equivalent tools for monitoring and troubleshooting message-driven systems. Proficiency in Python for services, scripting, data processing, or AI/ML workloads. An active Azure or AWS certification at associate level or higher. Experience with Docker, Kubernetes, Azure Container Apps, AKS/EKS, and infrastructure-as-code tools such as Terraform or Bicep.
