The Riskhandler platform is a business-critical commercial lines insurance rating and quoting system, serving insurance brokers across the UK and Ireland. Our team owns the product end-to-end from backend rating engine to REST API layer to data and were in the middle of an exciting technical evolution: modernising from a .NET Framework 4.8 foundation toward an API-first, cloud-ready architecture powered by .NET Core and React..

To keep us headed in the right direction, were looking for people who approach every problem with curiosity and rigour, who take genuine ownership of their work, and who see complexity as an opportunity rather than an obstacle. If you love digging into systems, finding elegant solutions, and helping the people around you grow, this role was written with you in mind..

What Youll Do :

- Design, build, and maintain features on the Riskhandler insurance rating and quoting platform (C# / VB.NET / ASP.NET Web API).

- Contribute to our API-first modernisation roadmap including REST API layer enhancements, CQRS pattern adoption, and early-stage migration planning toward .NET Core and React.

- Write clean, testable, and maintainable code; actively participate in code reviews and hold the team to high quality standards.

- Collaborate with product managers, architects, QA engineers, and UK-based stakeholders to translate requirements into robust technical solutions.

- Diagnose and resolve complex defects across the full stack backend services, data layer, and front-end. Contribute to and help evolve our Playwright (TypeScript) test automation framework.

- Drive improvements in engineering practices, coding standards, and design patterns across the team. Mentor junior developers, lead technical discussions, and play an active role in architecture decisions. Identify and champion opportunities for technical improvement in an open, collaborative way.

Were Excited to Learn More About You. Education : BE / B.Tech / M.Tech / MCA / MSc (Computer Science or related discipline). Experience : 89+ years of handson software engineering experience.

What We Need :

- Strong C# and .NET (Framework or Core) this is our nonnegotiable.

- Deep OOP fundamentals are essential: inheritance, polymorphism, encapsulation, SOLID principles.

- REST API development experience designing and building ASP.NET Web APIs with a solid grasp of HTTP, REST conventions, and integration patterns.

- SQL Server confident writing complex queries and stored procedures; comfortable understanding and evolving data models.

- JavaScript / TypeScript solid working knowledge of the modern JS/TS ecosystem; ability to contribute to frontend work and understand clientside architecture. Analytical and problemsolving mindset you think in systems, spot edge cases, evaluate tradeoffs, and propose solutions that are both pragmatic and wellreasoned.

- Endtoend ownership you take a feature from design discussion through to production, monitor it, iterate on it, and feel responsible for its quality. Strong communication and collaboration skills you can articulate technical decisions clearly to both technical and nontechnical stakeholders.

What Makes a Good Candidate Great :

- Familiarity with modern frontend frameworks React preferred; Angular also valued. Were on the path to React and want someone who can grow with us.

- Experience or exposure to .NET Core / .NET 6+ even if from a side project or POC.

- Knowledge of VB.NET part of our existing codebase is in VB.NET; not a requirement, but comfortable reading it is a plus. Understanding of architectural patterns: CQRS, MediatR, Dependency Injection, layered architecture patterns we are actively adopting.

- Experience working in a legacy modernisation context you know how to balance keeping the lights on while incrementally improving the architecture. Genuine passion for learning and adaptability technology will evolve and so will our stack; we want
