The Senior Software Engineer will lead technical decisions, mentor colleagues, and develop scalable web applications using C#, .NET, and SQL. Responsibilities include ensuring quality delivery and implementing best practices in code and CI/CD.
Who are we?
At Bright, we create cutting-edge software for accounting, payroll, tax, and practice management, supported by a team of talented individuals who are passionate about making a difference. Together, we lead the industry with innovative solutions and unparalleled customer support.
We’re all about creating opportunities for businesses to succeed — and for you to shine. Join us, and be part of a supportive, collaborative team that values your voice and contributions.
The Role
We are looking for a Senior Software Engineer to join the BrightPay engineering team, working on our cloud payroll platform. You will be writing C# and .NET, working with SQL, and shipping features that handle real payroll runs, tax calculations, and compliance requirements across multiple jurisdictions.
Payroll is a domain where correctness matters. Integrations with HMRC, Revenue, banks, and payment providers have hard deadlines and zero tolerance for errors — if you find that constraint interesting rather than tedious, you will thrive here.
As a senior member of a small, cross-functional team, you will lead technical decisions, mentor other engineers, and raise the bar on code quality and engineering practice.

Quality & Continuous Improvement
- Write clean, maintainable, well-tested code with comprehensive documentation that meets Bright’s engineering standards.
- Configure and maintain CI/CD pipelines with automated testing and deployment to support reliable software delivery.
- Identify and act on opportunities to improve development practices, tooling, code health, and maintainability across the engineering community.
- Collaborate with product managers, QA, and stakeholders to translate business requirements into robust technical solutions.
- Stay current with industry trends, emerging technologies, and engineering best practices.
Mentorship & Culture
- Provide technical guidance and mentorship to junior and mid-level engineers.

What We're Looking For
Essential
- Significant commercial experience developing web-based applications with C# and .NET.
- Strong experience with relational databases, including writing and optimising SQL queries.
- Proven experience with cloud platforms, particularly Microsoft Azure.
- Demonstrated ability to lead technical decision-making and mentor other engineers.
- Experience working in a fast-moving Agile environment.
- Strong familiarity with CI/CD practices, tools, and automated testing strategies.
- Architectural thinking — ability to design scalable systems and make sound technical trade-offs.
- Strong collaboration and communication skills, with the ability to work effectively across technical and non-technical stakeholders.
Desirable
- Experience building web front ends using JavaScript and modern frameworks such as React, Vue, or Blazor.
- Experience with containerisation technologies such as Docker or Kubernetes.
- Understanding of SOLID principles and software design patterns (MVVM, MVC, microservices).
- Knowledge of RESTful API design and development.
- Experience in B2B SaaS or domain-specific software (accounting, payroll, or professional services).
- Track record of mentoring engineers and driving technical standards across a team.
AI Awareness & Adoption
AI is becoming an integral part of how we work at Bright, and we want our engineers to be part of that journey. This is not an AI-specialist role, but we value an openness to AI tools and a curiosity about how they can improve the way we build software.
- Comfortable using AI-assisted development tools such as GitHub Copilot or similar to support coding, code review, and documentation tasks.
- An awareness of how large language models (LLMs) and AI-powered features are being applied in modern software products.
- A willingness to engage with and learn about AI capabilities as part of your ongoing professional development.
- An interest in how AI can improve development workflows, reduce toil, and support higher-quality output.

What you need to know about the Belfast Tech Scene
If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
