Senior Software Engineer

This role partners closely with project and engineering teams throughout the Initiation, Planning, Development, Deployment, and Ongoing Support & Maintenance phases of our Agile methodology, working from documented scope and deliverables. The ideal candidate is a strong hands-on software engineer with deep experience in C#, .NET Framework, modern .NET / ASP.NET Core, and SQL Server, along with practical experience building and integrating APIs, implementing secure authentication solutions, and leveraging modern AI-assisted development tools.

Key Responsibilities

• Learn and navigate a large existing codebase across UI, services, business logic, databases, and background processing components.

• Analyse and document current system behaviour, dependencies, and technical debt.

• Communicate complex technical concepts, architecture decisions, delivery progress, and risks effectively to both technical and non-technical stakeholders, ensuring alignment across engineering, product, operations, and business teams.

• Create characterisation and regression tests around critical functionality before implementing changes.

• Contribute to architecture, migration planning, and incremental modernisation initiatives.

• Develop APIs, services, background workers, UI components, and data access layers.

• Enhance CI/CD pipelines, automated testing, observability, and engineering standards.

• Collaborate with cross-functional teams and communicate technical decisions and risks.

Required Qualifications

• 7+ years of software engineering experience with C# and .NET.

• Strong experience with both .NET Framework and modern .NET / ASP.NET Core.

• Experience modernising or migrating large-scale enterprise applications.

• Strong SQL Server expertise including T-SQL, stored procedures, query tuning, indexing, and schema changes.

• Experience with Entity Framework / EF Core or similar ORMs.

• Strong understanding of software architecture, SOLID principles, dependency injection, and domain-driven design.

• Experience designing and building RESTful APIs and OpenAPI/Swagger.

• Experience with asynchronous processing, queues, scheduling, retries, and idempotency.

• Front-end experience with Vue.js (preferred), TypeScript, HTML, and CSS.

• Experience with automated testing, Git, and CI/CD platforms such as Azure DevOps or GitHub Actions.

• Understanding of application security, OAuth2/OpenID Connect, OWASP principles, and observability practices.

Preferred Qualifications

• Cloud experience with Azure.

• Docker, Kubernetes, and Infrastructure as Code (Bicep or Terraform).

• Experience modernising legacy web applications and reporting solutions.

• Experience with Redis, workflow engines, or approval-management systems.

• Experience using AI-assisted development tools.

• Daily user of AI-powered development tools such as Claude Code, GitHub Copilot, OpenAI, or similar platforms.
• Hands-on experience with n8n and other workflow orchestration platforms to automate engineering and business processes.
• Experience designing, implementing, and operating agentic workflows involving AI agents, tool usage, autonomous task execution, and multi-agent collaboration.
• Strong understanding of LLM integration patterns, RAG architectures, vector databases, MCP integrations, prompt engineering, and agent orchestration frameworks.
• Demonstrated ability to identify opportunities where AI can eliminate manual work, accelerate delivery, improve quality, or enhance customer experiences.
• Experience building production-grade AI solutions rather than simply experimenting with AI tooling.
