Full job description

Role Title: Senior Software Developer (CMS)

Overview:

As a Senior Software Developer at DOCOsoft, you will play a key role in the ongoing evolution of our business-critical software used across the London and Global Insurance Markets.

You will operate with a high degree of autonomy within a mature ASP.NET-based platform, contributing to complex feature development, architectural improvements, and production stability. This role combines strong hands-on engineering with system-level thinking in an environment where correctness, scalability, security, and data integrity are essential.

You will work within a cross-functional agile team delivering highly available, secure applications across on-premise and Azure-hosted environments.

Responsibilities:

Design and implement complex features and enhancements within a large, established .NET application and associated services.
Produce robust, maintainable, and well-tested code aligned with architectural best practices and long-term system sustainability.
Contribute to architectural and design decisions, applying patterns such as clean architecture, SOLID principles, CQRS, and domain-driven design where appropriate.
Lead by example in engineering quality, including unit testing, test-driven development, and peer code reviews.
Optimise and maintain SQL Server data structures, queries, and performance-sensitive components.
Diagnose and resolve complex defects, including production issues, performing root cause analysis where required.
Collaborate closely with Product, QA, DevOps, Infrastructure, and Data stakeholders to deliver secure, scalable, mission-critical solutions.
Provide technical guidance and informal mentorship to other developers within the team.
Contribute to continuous improvement of development standards, tooling, and engineering practices.

Key Requirements:

6+ years’ professional software development experience delivering and supporting production systems.
Strong C# and modern .NET (.NET Core / .NET 6+) experience in commercial environments.
Deep understanding of object-oriented design, clean architecture, SOLID principles, CQRS, and domain-driven design concepts.
Strong experience designing and developing RESTful APIs using ASP.NET Web API and OpenAPI/Swagger.
Strong SQL Server and T-SQL expertise, including performance optimisation.
Experience building and operating distributed or microservices-based systems.
Experience with automated testing frameworks (e.g., xUnit, Moq) and applying TDD where appropriate.
Strong Git-based development practices and experience working in collaborative code review environments.
Experience working within Agile/Scrum teams delivering highly available, secure applications.
Advanced understanding of identity and access management concepts, including OAuth2, OpenID Connect, and SAML-based SSO.
Experience developing secure, scalable applications deployed on Azure or AWS using IaaS and PaaS services.
Exposure to modern client-side frameworks (Vue.js, React, or Angular) to support full-stack collaboration.

DOCOsoft is a leading software and services provider to Lloyd’s of London and the broader London insurance market. Since our foundation, we have grown to become one of the leading insurance software specialists in the London Insurance Market.
