Senior Software Engineer - Front End/UX

Key Responsibilities

• Build and ship production Blazor applications in C# and .NET, owning the front-end from interaction design through to deployment.
• Make and defend design decisions, balancing visual polish, usability, accessibility, and engineering pragmatism.
• Establish and evolve front-end patterns, component libraries, and design conventions that other engineers can rely on.
• Contribute meaningfully to the back-end where required, including data access, APIs, and integration with our cloud platform.
• Partner with our existing front-end lead on architectural direction for the BrightPay user interface.

• Write clean, maintainable, well-tested code with clear documentation, applying the same care to front-end markup and styling as to back-end logic.
• 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, QA, and stakeholders to translate requirements into solutions that work technically and feel right for users.
• Stay current with engineering practices, front-end frameworks, and modern UX trends, applying what is genuinely useful rather than chasing novelty.

• Provide technical and design guidance to other engineers, raising the team’s collective ability on front-end and UX.
• Help shape engineering and design standards across BrightPay, fostering a collaborative environment where quality is the default.
• Work closely with the wider engineering team to ensure consistent direction and delivery.

What We Are Looking For

• Significant commercial experience developing web applications with C# and .NET as a true full-stack engineer.
• Demonstrable experience building production front-ends in Blazor, or equivalent experience in a component-based framework (React, Vue, Angular)
• Experience leading on UX or design decisions in a product engineering context, formally or informally.
• A strong eye for design and user experience, with work you can point to that shows it. We are looking for an engineer who sees layout, hierarchy, spacing, and interaction as part of the job.
• Strong experience with relational databases, including writing and optimising SQL queries.
• Comfortable working with cloud platforms, particularly Microsoft Azure, and with CI/CD practices and automated testing.
• A track record of mentoring or guiding other engineers, with experience working in a fast-moving Agile environment.
• Architectural thinking, with the ability to make sound trade-offs across both front-end and back-end concerns.
• Strong collaboration and communication skills, with the ability to work effectively across technical and non-technical stakeholders.

• Familiarity with design tools (Figma, Sketch) and the ability to work directly from designs or produce credible mockups when designs are not available.
• Understanding of accessibility standards (WCAG) and a habit of building with them in mind.
• Knowledge of RESTful API design, SOLID principles, and common
• software design patterns.
  Experience in B2B SaaS or domain-specific software (accounting, payroll, or professional services).
• Experience with containerisation technologies such as Docker or Kubernetes.

AI Awareness & Adoption

• 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.
