This is a great opportunity to work in an environment that embraces cutting-edge technologies, with a strong focus on React, TypeScript, and modern front-end architecture for AI-powered products.

• Collaborating within an agile, Scrum-driven team, participating in sprints and planning sessions
• Contributing to automated testing, CI/CD pipelines, and monitoring production front-end systems
• Engaging in peer code reviews and mentoring junior engineers to support knowledge-sharing and team growth, When it comes to recruitment, we’re interested in your work experience, skills, and overall personality. Because diversity makes the workplace stronger and is necessary for SaleCycle’s success, we are intensifying efforts to incorporate concrete actions to help us improve in this area.

We’re looking for someone who is passionate about writing high-quality front-end software and thrives in a collaborative team environment., * Strong, hands-on experience with React and TypeScript in production applications

• Solid grounding in modern JavaScript/TypeScript, component architecture, and state management
• Experience building UI for data-rich or AI-powered products (analytics dashboards, recommendation surfaces, real-time personalisation, or similar)
• Comfortable consuming and helping shape RESTful (or similar) APIs from front-end code
• Familiar with git or other distributed source control systems
• A problem-solver with a proactive approach to diagnosing and resolving issues
• Passionate about writing clean, maintainable, and scalable front-end code
• Experience building and maintaining automated test suites with Cypress/Jest, or similar
