Job Type : 12+ Months Contracting Role

AI-Driven Development:
• Hands-on fluency with AI-assisted development tools — using them daily and understanding their strengths, failure modes, and appropriate limits.
• Experience building and orchestrating agents: designing agent loops, managing context and memory, composing multi-step pipelines from discrete skills, and handling failure modes gracefully.
• Ability to define reusable, well-scoped skills with clear interfaces and predictable behavior — the building blocks of reliable agentic workflows.
• Prompt engineering as a first-class discipline: structured prompting, output validation, iterative refinement, and the ability to teach these practices to others.
• Practical experience evaluating agent behavior: defining what good looks like, building evals, and holding AI-generated work to the same standards as hand-authored code.




• Ability to identify which parts of a development workflow are good candidates for automation or AI assistance and which are not.

Cloud Native & Platform:
• Strong working command of containerization and orchestration — building and running services that are scalable, reliable, and operationally simple.
• Experience with major cloud platforms and their managed services, with a preference for platform-native solutions over custom infrastructure.
• Infrastructure as code practices applied consistently across environments.
• Building and maintaining CI/CD pipelines with an emphasis on fast feedback, automated quality gates, and safe deployment patterns.
• Distributed systems fundamentals applied in practice: service communication, event-driven patterns, observability, and fault tolerance.

Application Development:
• Deep expertise in C# / .NET — platform internals, async programming, and performance optimization.
• API design and implementation using ASP.NET Core, including REST principles, versioning, and middlewa
