Key Responsibilities:
• Collaborate with the CTO, Head of Software Delivery, and other Software Engineers to implement the technical vision for the compliance application (backend and frontend).
• Write clean, scalable, and well-documented C# code in .NET and .NET Core.
• Develop frontend code using MVC and React, with strong HTML/CSS knowledge.
• Review code to ensure adherence to company standards and best practices.
• Mentor junior developers, fostering their professional growth.
• Make technical decisions in line with the organisation's architecture and strategy.
• Work with the Product Team to provide estimates, identify dependencies, and refine requirements.
• Actively participate in Agile Scrum processes.
• Oversee technical implementation of projects, ensuring timely delivery and resolving issues.
• Troubleshoot and resolve software issues, implementing preventative measures.
• Research and implement new technologies to improve development processes and solutions.
• Collaborate with stakeholders to ensure software meets business needs and user requirements.
• Effectively communicate complex technical information to technical and non-technical stakeholders.
• Document code, architecture, and systems effectively.
About you:
• Proven commercial experience developing modern web applications using Core and C#, with expertise in application architecture, performance optimization, and maintainable code.
• Solid understanding of front-end development with JavaScript/TypeScript, using frameworks like React or Blazor, and a keen eye for clean, responsive user interfaces.
• Proficiency in SQL Server and/or Cosmos DB, including writing and optimizing complex queries and data modeling for web-scale applications.
• Experience in designing, consuming, and documenting RESTful APIs; comfortable with JSON, authentication (OAuth, JWT), and third-party integrations.
• A track record of working with distributed systems, microservices, and event-driven architectures.
• Skilled in Git-based version control workflows and CI/CD pipelines (Azure DevOps, GitHub Actions, or similar).
• Strong understanding of software testing principles, with experience in unit and integration testing frameworks (xUnit, NUnit, MSTest).
• Organized, methodical, self-directing, and capable of mentoring junior developers.
• Comfortable contributing to agile development processes (sprint planning, daily stand-ups, code reviews, retrospectives).
• Able to take initiative and own features/technical problems end-to-end, balancing independence with collaborative decision-making.
• Familiarity with Azure services (App Services, Azure Functions, Key Vault, Application Insights, Service Bus).
• Exposure to containerization and orchestration tools (Docker, Kubernetes).
• Experience working with design systems or UX/UI teams.
• Understanding of software architecture patterns (clean architecture, domain-driven design, CQRS).
• Comfortable with asynchronous programming, parallel processing, and performance profiling.
• Experience building and securing multi-tenant SaaS applications.
• Contributions to developer documentation or internal technical specifications.
• Working knowledge of Atlassian products (JIRA, Confluence) or equivalent agile/project management tools.
This hybrid role offers quality office space at Stockley Park UB11 1FW for your use as often as you like. The team attends the office three to ten days a month, depending on business needs.
