• Working as a senior member of the R&D team to lead and deliver changes across a web-based SaaS platform used in the education and training sector
• Leading by example in writing high-quality, maintainable, and testable code using C# (.NET) for APIs and modern JavaScript frameworks, especially Angular and React
• Maintaining development deadlines, provide accurate time estimates, and deliver work at high speed and quality standards
• Actively participating in resolving live issues and supporting the release process, including last-minute blockers or urgent production incidents
• Taking ownership of critical areas of the platform, demonstrating initiative, responsibility, and reliability across all stages of development
• Working closely with the Product team to understand business requirements and translate them into technical solutions
• Collaborating with UI/UX designers to deliver accessible, intuitive, and visually polished user interfaces
• Communicating effectively with internal stakeholders and external clients where required, offering clear updates, technical guidance, and realistic timelines
• Performing code reviews and provide constructive feedback to other developers to raise overall team standards
• Mentoring and supporting junior developers, fostering a culture of knowledge sharing and continuous improvement
• Understanding and work with various environment configurations and deployment scenarios (e.g., UAT, staging, live)
• Working within Agile Scrum methodologies, contributing to sprint planning, retrospectives, and daily stand-ups
• Engaging with QA engineers to ensure efficient testing coverage, and suggest more efficient ways to verify product quality when full UI automation is not viable.
• Contributing to efforts around technical documentation (e.g., READMEs, confluence pages) to improve maintainability across the codebase
• Applying an understanding of Azure cloud services (e.g., App Services, storage, identity) to help deliver scalable, cloud-first solutions

What we are looking for

The ideal candidate is proficient in modern JavaScript frameworks (Angular or React), RESTful C# APIs, and familiar with Azure cloud services and multi-environment configurations.
