Senior Software Developer (CMS)

Senior Software Developer – Hybrid

As a Senior Software Developer at DOCOsoft, you will play a critical role in designing, building, and evolving high-quality software systems that power solutions for the London and Global Insurance Markets. You will operate with a high degree of autonomy, technical authority, and accountability, contributing not only through hands-on development but also through architectural decision-making, technical leadership, and mentorship.

You will work closely with product owners, architects, and fellow engineers to translate business needs into scalable, resilient, and maintainable systems, while actively raising engineering standards across the team.

Role Description:

This role is for an experienced engineer who owns outcomes, not just tasks. You will be responsible for shaping technical solutions end-to-end from requirements and design through implementation, testing, deployment, and ongoing evolution.

You will be expected to make sound technical decisions, identify and mitigate risk early, challenge assumptions, and contribute to the long-term health of the codebase and platform. You will act as a technical reference point within the team and provide guidance to less experienced engineers.

Responsibilities:

• Own the design and implementation of complex features and subsystems, ensuring they meet functional, performance, security, and maintainability requirements.
• Drive technical design and architecture discussions, producing clear, pragmatic designs aligned with system and business goals
• Take accountability for code quality, system reliability, and operational stability, not just individual contributions
• Mentor and support mid-level and junior engineers, providing technical guidance, feedback, and code review leadership
• Identify technical debt, scalability issues, and architectural risks, and proactively propose and deliver improvements
• Collaborate closely with product owners and stakeholders to clarify requirements, challenge ambiguity, and shape solutions
• Lead by example in engineering best practices, including testing strategies, CI/CD usage, documentation, and secure coding
• Contribute to estimation, planning, and prioritisation, bringing realism and technical insight to delivery commitments
• Participate in production support and incident resolution, driving root-cause analysis and long-term fixes
• Influence and improve development processes within an agile/scrum environment

Skills and Qualifications

• 5+ years of professional software development experience, including delivery of production systems at scale
• Proven experience owning features or systems from design through production
  

Core Technical Skills

• Strong expertise in C# and .NET Core
• Deep experience with ASP.NET MVC / Web APIs
• Strong command of SQL Server and T-SQL, including performance considerations
• Advanced usage of Git, including branching strategies and code review workflows

Engineering Practices

• Solid understanding and practical application of software architecture principles, design patterns, and SOLID
• Hands-on experience with test-driven development and layered testing strategies
• Strong experience with:
  • Unit testing (xUnit, NUnit)
  • Mocking frameworks (Moq or equivalent)
  • Integration and E2E testing (e.g., Playwright)
• Experience designing and consuming RESTful APIs with OpenAPI (Swagger)

Architecture & Platforms

• Strong understanding of authentication and authorization (OAuth2, OpenID Connect; SAML knowledge a plus)
• Familiarity with cloud-native patterns, resilience, and scalability concerns

Nice to Have

• Frontend experience with React, Angular, or Vue.js
• Experience with Docker and container-based deployments
• Practical involvement in CI/CD pipeline design and optimisation
• Experience with caching strategies (e.g., Redis)
• Exposure to OData, UML, or architectural documentation
• Previous experience influencing or defining technical standards
• Agile certifications (CSM / PSM)

What Success Looks Like in This Role 

After 6–12 months, a successful Senior Engineer at DOCOsoft:

• Owns delivery end-to-end: Independently designs, builds, ships, and supports complex features with predictable outcomes
• Improves system quality: Reduces technical debt, improves maintainability, and increases production stability
• Sets a high engineering bar: Models strong code quality, testing, documentation, and effective code reviews
• Multiplies team impact: Mentors engineers, unblocks teammates, and acts as a technical reference point
• Applies sound technical judgment: Makes balanced trade-offs and challenges requirements to avoid risk or over-engineering
• Owns production outcomes: Takes responsibility for incidents, drives root-cause analysis, and implements lasting fixes
