Senior Software Engineer

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., Technical Leadership & Delivery

• Architect and implement scalable, production-ready applications across front-end and back-end, ensuring robust, efficient, and performant delivery.
• Lead technical decision-making within your squad, balancing innovation with pragmatic delivery.
• Design and build secure, high-quality back-end services integrated with our cloud platform.
• Drive best practices in code quality, testing, security, and observability across the team.
• Contribute to architectural decisions and technical strategy, shaping how we build at Bright.

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.
• Help shape team culture and engineering standards, fostering a collaborative and high-quality delivery environment.
• Work closely within cross-functional teams to ensure consistent, high-quality software delivery., 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.

Do you have experience in Vue.js?, 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.

You'll have genuine flexibility in how you work, backed by modern practices that adapt to how work actually gets done today. We recognise and celebrate strong performance, support your wellbeing, and give you real opportunities to grow, not just in role, but in career. We're proud of the culture we've built.
