Sanderson

City Of London / Global

Senior Software Engineer

Job Description

We’re working with a leading specialty insurance organisation looking for a hands‑on Senior Software Engineer to join its Technology team and help scale an AI‑native approach to software development.

This is not an AI Engineer role focused on building LLM or RAG products. The focus is on experienced software engineers who are already using AI tools and agents to improve how software is designed, built, tested and delivered.

What you'll be doing

Build full-stack applications using C#/.NET, React and TypeScript
Develop APIs, integrations and microservices
Build cloud-native solutions, ideally within Azure
Use AI agents across requirements, specifications, coding, testing and delivery
Review and validate AI-generated code
Contribute to CI/CD, Infrastructure as Code and deployment automation

What we're looking for

Strong C#/.NET software engineering experience
Full-stack experience with React and TypeScript
APIs, microservices and distributed systems experience
CI/CD, Docker, Kubernetes and Terraform/IaC exposure
Genuine AI-native development experience using tools such as Claude Code, GitHub Copilot, Codex or similar
Spec-Driven Development experience is highly desirable

The key requirement is being able to demonstrate how AI has materially changed the way you build and deliver software, rather than simply using ChatGPT or Copilot occasionally.
