Senior Software Developer

🚀 Senior Software Developer Remote within the UK, with occasional team meet-ups in London when useful About Webigence and the Role Webigence has 25+ years of experience crafting UX-first, often highly complex software. Our engineers pair pragmatic, forward-thinking development practices with an obsession for intuitive design, shipping products that feel effortless even when the logic underneath is anything but. Alongside developing our own SaaS products, we build and support important software platforms for a small number of long-standing clients. We are now looking for a Senior Software Developer to join Webigence in a predominantly dedicated role working with a profitable, established healthtech business. Approximately 95% of your time will be committed to its software projects, product development and technical priorities. You will be employed by Webigence and become part of our experienced, collaborative development team, while also developing a close working relationship with the healthtech client's stakeholders and taking substantial ownership of the systems and priorities assigned to you. This offers the best of both worlds: the continuity and influence that come from becoming deeply involved with one successful business, backed by the wider experience, support and technical collaboration of the Webigence team. The remaining portion of your time may occasionally be spent supporting other Webigence products or long-standing client systems where useful. This is a hands-on senior development role for someone who enjoys understanding complex requirements, making sensible technical decisions and delivering reliable software that stands up in the real world. We are deliberately pragmatic. We use AI and newer technologies where they clearly solve real problems, but we are not interested in chasing hype. We care about clear thinking, sensible architecture, intuitive user experiences and software that is maintainable, supportable and commercially valuable. --- 🌟 Your Impact Become a key technical contributor to an established healthtech business. Approximately 95% of your time will be committed to its projects and development priorities, allowing you to make a sustained contribution rather than moving briefly between unrelated assignments. Raise the bar sensibly. Set high standards without over-engineering, and help us make good technical decisions that balance speed, quality, maintainability and commercial reality. Build software that matters. Your work will directly contribute to the continued development and improvement of business-critical healthtech systems and services. Own the craft. Understand the problem, ask good questions, ship the solution, diagnose issues properly and improve what already works. Work across the stack. You will contribute to .NET APIs, Angular front ends, SQL Server-backed workflows, Azure-hosted services, integrations, automations and user-facing functionality. Build lasting knowledge. Because this is a predominantly dedicated role, you will gain a detailed understanding of the client's systems, requirements and priorities, giving you the context needed to make increasingly valuable contributions over time. Represent Webigence well. You will work closely with both Webigence colleagues and client stakeholders, communicating clearly, following through on commitments and helping maintain a productive long-term partnership. --- 🧭 Role Snapshot Senior Software Developer Remote within the UK, with occasional team meet-ups in London when useful Employed by Webigence, with approximately 95% of your working time committed to an established healthtech client You will: Design, build and maintain features across the stack, including .NET / C# APIs, Angular / TypeScript front ends, SQL Server, Azure services and related integrations.Spend approximately 95% of your working time on healthtech projects, development tasks, technical improvements and production support.Build a strong understanding of the client's systems, business requirements and technical priorities.Work closely with client stakeholders and the wider Webigence team to turn complex requirements into intuitive, maintainable software.Take ownership of assigned work from initial investigation and technical design through to implementation, testing, release and follow-up.Investigate and diagnose issues properly across browser behaviour, APIs, application logs, Azure services, external integrations and database layers.Write clean, maintainable and tested code that can be understood and supported by the wider team.Contribute to technical discussions, challenge assumptions constructively and explain the trade-offs behind your recommendations.Help improve established systems without assuming that everything needs to be rewritten or replaced.Contribute to the reliability, security, performance and maintainability of the systems you work on.Use modern tooling sensibly, including CI/CD pipelines, Azure DevOps / GitHub Actions, Azure monitoring and logging tools, and AI-assisted development tools where appropriate.Occasionally contribute to other Webigence products or long-standing client systems when required.Be comfortable working in a remote-first team where clear written communication, ownership and self-direction matter. --- ✅ You Might Be Our Senior Developer If...
