Beyond implementation, you'll contribute to technical solutions and architectural decisions, application performance and maintainability. Additionally, you'll collaborate with other engineers to deliver reliable and scalable solutions.
Responsibilities
- Take ownership of complex software development tasks, from technical design and implementation through delivery and ongoing maintenance.
- Maintain and evolve existing applications while contributing to the incremental modernization of our front-end architecture.
- Investigate complex technical challenges, identify root causes and implement sustainable solutions that consider long-term maintainability.
- Collaborate with product teams, designers and engineers to translate requirements into practical technical solutions, identifying dependencies and trade-offs.
- Contribute to architectural discussions and technical planning, helping guide engineering decisions and identify opportunities for improvement.
- Support the development of other engineers through code reviews, knowledge sharing and mentoring, while promoting consistent engineering practices across the team.
Requirements
Mandatory

Optional
- Experience with established web technologies such as Spring, Stripes, JSP, Apache Tomcat or jQuery.
- Familiarity with NextJS and TypeScript or experience with modernizing established web applications.
Technical Skills
- Web architecture: Strong understanding of browser behavior, the DOM, HTTP, server-side rendering, client-to-server interactions and API integration.
- Front-end engineering: Knowledge of component-based architectures, browser compatibility, responsive design principles and web accessibility standards (WCAG).
- Application development: Ability to navigate complex Java-based web applications, understand application lifecycles and troubleshooting issues across front-end, back-end and data components.
- Software quality & performance: Experience with automated testing approaches (e.g.JUnit & Playwright), debugging, performance optimization and secure coding practices to ensure reliable, maintainable applications.
