Senior Developer

You'll be joining a team of experienced senior developers, collaborating day-to-day on the design, build, and delivery of robust full-stack solutions for enterprise clients. This role emphasises peer collaboration, pairing, reviewing, and problem-solving alongside other seniors, sharing ownership of architectural decisions, and collectively raising the bar on code quality and technical direction. You’ll also help mentor more team members as the team grows. Key Responsibilities Design, develop, test, and maintain full-stack applications using C#/.NET across the back end and modern JavaScript frameworks on the front end. Lead technical design discussions and contribute to architectural decisions on new and existing systems. Translate client business requirements into well-documented technical solutions, including preparing system design documents. Build and optimise data-driven features backed by Microsoft SQL Server, including stored procedures, performance tuning, and integration with various reporting and ETL technologies. Take responsibility for code quality - perform code reviews, uphold coding standards, and champion unit testing and automated testing practices. Mentor and support junior and intermediate developers, sharing knowledge through pairing, reviews, and technical guidance. Participate in the full software development lifecycle: requirements gathering, estimation, implementation, deployment, and post-release support. Work directly with clients in the health sectors to troubleshoot issues, scope enhancements, and deliver responsive service. Contribute to continuous improvement of development practices, including CI/CD, source control workflows, and DevOps tooling. Help the team safely and effectively adopt modern productivity tools, including AI-assisted development tools where appropriate. Qualifications A relevant tertiary qualification. 5+ years of relevant commercial experience in full-stack .NET development (minimum). Prior lead or senior developer experience, including mentoring and technical ownership (preferable). Strong C# and .NET skills across modern .NET (ASP.NET Core, Web API, Entity Framework); experience with MVC and AJAX patterns. Front-end development experience with modern frameworks (e.g., Angular or React) and solid HTML/CSS/JavaScript/TypeScript fundamentals. Strong Microsoft SQL Server skills, including complex queries, stored procedures, and performance tuning. Hands-on experience with cloud applications would be a bonus. Familiarity with source control (Git), CI/CD pipelines, and cloud platforms (Azure preferred). Experience with automated testing frameworks (xUnit, NUnit, or similar). Exposure to, or practical experience with, AI-assisted development tools (e.g., GitHub Copilot, Claude, Cursor) for accelerating coding, reviews, or testing would be a bonus. The ability to work effectively both individually and as part of a team - accepting personal accountability and displaying a commitment to collaborate. Strong written and oral communication skills, including the ability to prepare system design documents for a client and explain technical concepts to non-technical stakeholders.
