About the Company
My client is a highly successful, specialist software company whose products support their clients on a global basis. They develop mission-critical software and work closely with major industry partners, and are able to offer a stable yet highly innovative environment.
The Role
Our client is pioneering the future of software engineering within their sector/field. In this role, AI agents write a significant portion of the primary C# codebase, and they require an experienced Senior Developer to direct, orchestrate, and validate this output.
You will not just be coding in a corner; you will act as the "human-in-the-loop" engineer, ensuring AI-generated components are woven into robust, enterprise-grade systems where absolute reliability is critical.
Key Responsibilities:
* AI Orchestration & Review: Direct, monitor, and review the code outputs generated by AI agents.
* Integration & Architecture: Piece together AI-generated code blocks into cohesive, scalable, and robust software solutions.
* Advanced Debugging & Hand-Coding: Step in with strong manual coding skills to refactor, optimize, and fix complex logical errors when the AI falls short.
* Rigorous Testing: Implement a methodical approach to testing and debugging live, high-stakes logistics systems.
* Process Optimization: Continuously question current workflows and suggest improvements to the AI prompt strategies, tooling, and general codebase.
* Project Management (Upper Salary Band): Plan, prioritize, and manage project delivery timelines while managing stakeholders alongside your core development duties.
Essential Criteria:
* Commercial Experience: Minimum 4+ years of professional C# development experience.
* AI Environment Experience: Minimum 2+ years of experience working actively with AI coding tools, LLMs, or automated code-generation agents.
* Technical Mastery: Exceptional hand-coding ability with a deep understanding of C# architecture, rather than a passive acceptance of generated outputs.
* QA Mindset: A highly methodical approach to system integration, debugging, and comprehensive unit/integration testing.
* Soft Skills: A confident, articulate communicator who is comfortable constructively challenging architectural ideas and proposing innovations.
* Commute: Full commitment to working on-site daily at the North Norwich office.
