What's the Project?
Our client is a well-established company in the luxury retail industry undergoing a significant technology transformation. Newfire is taking ownership of the client's engineering ecosystem, including its core e-commerce platform, multiple online storefronts, and ERP integrations, with the goal of modernizing the platform and dramatically accelerating software delivery.

As part of this engagement, we're building a team of experienced engineers who enjoy solving complex technical challenges, improving large production systems, and working through real-world technical debt. This is not a greenfield project—it's an opportunity to make a meaningful impact by increasing reliability, scalability, and development velocity across a business-critical platform.
Your day-to-day activities:
Take part in Scrum ceremonies (daily stand-up, retrospective, planning) Design, develop, test, and maintain both backend (Java/Spring Boot) and frontend (React/Next.js) functionality. Continuously improve the existing production codebase by reducing technical debt and increasing maintainability. Refactor complex legacy components while ensuring comprehensive automated test coverage. Write clean, maintainable, and well-tested code following engineering best practices. Collaborate closely with Product Managers, Designers, QA, and fellow Engineers to deliver high-quality customer-facing features. Collaborate with Quality Assistance (QA) to write end-to-end tests and own the full life-cycle of feature development from planning to production deployment. Review code, provide constructive feedback, and actively contribute to improving engineering standards. Take ownership of features from implementation through deployment and production support. Be proactive in identifying opportunities for technical improvements and process optimization. Stay current with modern development practices and leverage AI-powered development tools to improve productivity and code quality. Be accountable for delivering reliable, scalable, and maintainable software that provides business value. As a Senior team member, you will be expected to actively participate in our hiring processes by serving on interview panels for future roles across the company.
Please note that employment will be contingent upon providing documentation verifying your legal work authorization in the country of residence, in accordance with applicable law.
