📋 Description

• Develop full-stack software using .NET and React. • Write unambiguous specifications, break requirements down into verifiable plans, and define acceptance criteria. • Build and manage context for LLMs, including instructions, constraints, examples, tools/MCPs, and context-window management. • Apply generative AI and agentic tools to software development, with systematic human validation. • Evaluate, validate, and correct AI-generated code and code developed by third parties. • Create high-quality, well-organized, and testable code. • Develop and maintain automated unit and/or integration tests. • Use Git and collaborate through Pull Requests. • Work with SQL databases, data modeling, and agile practices.

🎯 Requirements

• At least 3 years of software development experience, with strong proficiency in at least one of the stacks (.NET and React) and a proven ability to work across the others with AI assistance. • Spec-Driven Development as a core competency: write unambiguous specifications, break them down into verifiable plans, and define acceptance criteria that serve as a contract for humans and agents (e.g., /specify, /plan). • Context Engineering: build and manage context for LLMs—including instructions, constraints, examples, tool/MCP selection, and context-window control. • Apply generative AI and agentic tools to software development with responsibility, critical judgment, and systematic human validation. • Critically review code you did not write: evaluate, validate, and correct AI-generated and third-party output with the same rigor applied to your own code. • Ability to write high-quality, well-organized, and testable code, with proficiency in object-oriented programming and/or sound design principles. • Experience with automated testing (unit and/or integration). • Use Git for version control and collaboration through Pull Requests. • Experience with SQL databases and data modeling fundamentals. • Experience with agile practices (Scrum, Kanban, or XP). • Knowledge of Python.
