• Design, develop, and maintain scalable backend services and APIs using C#/.NET, delivering high‑quality code that adheres to Sitecore engineering standards.
• Build and maintain CI/CD pipelines to ensure reliable, consistent, and frequent deployments using GitHub Actions or equivalent systems.
• Develop comprehensive automated tests (unit, integration, E2E) to ensure robustness and maintainability across services.
• Work with cloud‑native technologies including Azure, Docker/Kubernetes, and distributed messaging (Kafka) to support multi‑tenant, high‑performance architectures.
• Collaborate closely with Engineering Manager, Product Owner, Lead Developer, QA, and cross‑functional teams to refine user stories, acceptance criteria, and technical design.
• Act as a proactive driver of engineering quality and delivery by participating in architectural discussions, reviewing code, sharing best practices, and supporting departmental upskilling.

What you need to Succeed:

• Strong proficiency in C#/.NET with solid understanding of object‑oriented design, modern architectures, and clean code principles (SOLID, refactoring).
• Hands‑on experience with Git, collaborative branching strategies, and modern development workflows.
• Proven experience building cloud‑based, containerized solutions using Azure, Docker, Kubernetes, and distributed systems patterns.
• Strong background in CI/CD pipelines, automated testing practices, and DevOps‑oriented delivery.
• Solid understanding of relational or NoSQL databases, data modeling, and performance optimization using profiling tools.
