As a Senior Software Engineer (React) at Syspro, you will design, build, and take ownership of high-quality, scalable, and user-focused web applications and components using React and modern front-end technologies. You will drive front-end architecture and engineering standards, solve complex technical problems, and support the growth of less experienced engineers, working closely with Product, UX/UI, Quality Engineering, Architecture, and back-end teams to deliver secure, performant, and accessible enterprise software experiences.
This is a hands-on engineering role with clear expectations for technical leadership, system design input, and team enablement.
Responsibilities
- Design, develop, test, and maintain high-quality, scalable, and maintainable web applications and components using React, TypeScript, and modern front-end technologies.
- Take end-to-end ownership of complex work: analysis, design, implementation, testing, deployment readiness, and operational support.
- Build reusable, modular React components and front-end libraries using functional components, hooks, component composition, and appropriate state-management approaches.
- Translate product requirements and UX designs into robust, production-quality solutions, working closely with UX/UI to implement designs accurately and consistently.
- Integrate front-end applications with REST APIs and back-end services, including asynchronous JavaScript, JSON data handling, and client-side routing.
- Contribute to the evolution of front-end architecture, frameworks, and engineering standards, including component design, state management, routing, and client-side data management.
- Lead design reviews and architecture discussions across teams, and guide others in applying strong design principles (e.g., component composition, reusability, separation of concerns).
- Set and uphold front-end coding standards and engineering practices within the team.
- Promote reuse and consistency through shared components, design systems, and common engineering patterns; identify and address technical debt while balancing delivery priorities with long-term maintainability.
- Help define and reinforce a strong testing culture, including unit, component, integration, and end-to-end automated tests.
- Investigate defects to identify root causes rather than only symptoms, and raise the quality bar through reviews, coaching, and pragmatic improvements to the Definition of Done.
- Optimise front-end performance (load time, rendering, bundle size) using techniques such as code splitting, lazy loading, caching, and memoisation.
- Build responsive applications that provide a consistent experience across supported browsers, devices, and screen sizes, developed in line with recognised accessibility (WCAG) standards.
- Apply secure front-end development practices, understand common web application vulnerabilities, and ensure secure handling of authentication, tokens, application state, and sensitive information.
- Use Azure DevOps effectively for delivery transparency and discipline (work items, code reviews, pipelines, traceability), and work confidently with Git-based source control, including branching, pull requests, and merge strategies.
- Contribute to healthy repository structure and CI/CD practices; help the team improve deployment and release readiness over time.
- Factor SaaS delivery considerations (multi-tenancy, scalability, operability) into front-end architecture and design decisions.
- Contribute to modernising legacy user interfaces and workflows into modern, componentised React experiences, working with backend teams where legacy systems are involved.
- Collaborate with Product, UX/UI, Architecture, Quality, and back-end engineering teams to deliver secure, performant, and intuitive enterprise software experiences.
- Influence product and roadmap direction through strong technical input and clear articulation of trade-offs.
- Shape solution requirements and contribute to product design discussions with a customer-value mindset.
- Coach and mentor engineers across the team, supporting juniors with practical guidance and feedback.
- Drive team-wide improvements (ways of working, quality practices, technical patterns, shared standards).
- Surface technical risks, dependencies, and impediments early and manage them effectively.
- Lead by example in delivery quality, engineering discipline, and technical initiatives.
- Provide transparent delivery execution and reporting through disciplined use of Azure DevOps.
Requirements
Minimum Level of Education
- Bachelor's degree in relevant field (e.g. Computer Science, Software Engineering, Information Systems etc.)
Beneficial Qualifications
Relevant certifications
Minimum Experience
- 6 - 9 years of software development experience, with demonstrated ownership of complex systems
- Strong professional experience in React and TypeScript, including component architecture, React Hooks, state management, and performance optimisation

- Solid experience integrating front-end applications with REST APIs and back-end services, including asynchronous JavaScript, JSON data handling, and client-side routing
- Practical experience with modern front-end build and package-management tooling (e.g., npm, Vite, or Webpack), Git-based source control, and browser developer tools for debugging
- Practical experience working in an agile delivery environment and using Azure DevOps (or equivalent), with the ability to mentor others in good usage
Beneficial Experience
- Experience in enterprise software, ERP, SaaS, or complex multi-team product environments
- Familiarity with back-end technologies (e.g., C#/.NET) and API design, to support effective collaboration with back-end engineering teams
- Experience with automated testing frameworks (Jest, Vitest, React Testing Library) and browser-based end-to-end testing (Playwright, Cypress, or similar)
