Full-Stack Backend-Focused Developers
Posted
Summary
Backend-focused full-stack developer building internal apps for wealth management users and clients, using Java 21/Spring Boot microservices on the backend and React 19 with micro-frontend architecture on the frontend. Day-to-day work spans REST API design, Kafka/MQ messaging, SQL databases, and modern frontend tooling and testing.
Expert-level backend knowledge with junior-to-mid-level frontend capabilities
Required Backend Technical Skills . Strong proficiency in Java ( Java 21 ) with deep understanding of core concepts, coupled with expert-level
Spring Boot
framework knowledge (MVC, Data, Security, Cloud). . Strong understanding of modulith/microservices patterns and best practices, alongside experience with relational databases (e.g.,
MariaDB , PostgreSQL) and SQL optimization. . Strong knowledge of RESTful API design principles and experience with message queues (Kafka, IBM MQ, etc.). . Proven expertise in unit testing and integration testing (JUnit, Mockito, Karate), and a strong understanding of design paerns and SOLID principles.
Required Frontend Technical Skills . Expert-level Typescript
React 19
experience, demonstrating deep understanding of hooks, context, and component lifecycle. Strong proficiency in Redux, Redux Toolkit (RTK), and RTK Query for state management and data fetching. . Expert-level knowledge of modern web technologies:
Micro Frontend (MFE)
architecture (Module Federation, Single-SPA), advanced HTML5, semantic markup, and expert-level CSS3 (Flexbox, Grid, responsive design, CSS-in-JS like Styled Components, Emotion). . Strong command of modern JavaScript/TypeScript (ES6+), frontend build tools (Webpack, Vite), and testing frameworks (Jest, React Testing Library, Cypress, Playwright). . Proven expertise in performance optimization (code splitting, lazy loading) and practical application of design systems and component libraries (e.g., Storybook) for consistency and efficiency across frontend engineering. Key Responsibilities . You will design, develop, and maintain full stack applicationsusing Java Spring Boot and React for our internal users and clients in WealthManagement. . You will build and optimize RESTful APIs and microservices. . You will implement and maintain Micro Frontend (MFE)architectures. . You will drive best practices across the entire technology stack. . You will collaborate with business analysts, project managers,business stakeholders, and other tech teams to integrate and deliverhigh-quality products. . You will troubleshoot complex production issues spanning frontendand backend. . You will drive technical innovation and continuous improvement initiatives. . You will participate in system design discussions and contribute to the technical roadmap.
