We are looking for an experienced back-end developer to design, build, and maintain scalable, high-performance services supporting applications used by millions of people. In this role, you will contribute to the architecture and development of new solutions from the ground up, balancing product delivery with technical excellence. You will work primarily with Java, Spring Boot, and Node.js in a cloud-native environment, leveraging AWS, microservices, and modern engineering practices. Quality, security, observability, and automated testing will be central to your work. You will collaborate closely with Product and Front-end teams, bringing autonomy, problem-solving skills, and a strong focus on business outcomes. This is an opportunity to shape technical solutions in a challenging, collaborative environment that embraces innovation and AI-powered software development.

Back-end Development and Architecture: Design, develop, and maintain scalable, reliable back-end services using Java and Node.js, including Backend for Frontend (BFF) layers, supporting high-transaction-volume applications.
Solution Design and Implementation: Lead technical development from initial conception through production delivery, building new features and services while balancing business priorities with technical debt reduction.
Code Quality and Automated Testing: Maintain a healthy, sustainable codebase by applying Clean Code, SOLID principles, design patterns, and comprehensive unit and integration testing practices.
Cloud Infrastructure and Microservices: Develop and operate cloud-based solutions using AWS, containerization, and microservices architectures to support scalability, resilience, and maintainability.
APIs and Asynchronous Communication: Design, implement, and consume RESTful APIs while working with MongoDB and asynchronous messaging technologies such as AWS SQS.
Observability and Security: Monitor application performance in production, improve system observability and resilience, and implement appropriate API security and data protection practices.
AI-Enabled Engineering: Integrate generative AI assistants into daily development workflows to accelerate coding, testing, documentation, and problem-solving while maintaining high standards of quality and security.
Cross-Functional Collaboration: Partner with Product and Front-end teams to translate requirements into effective technical solutions, communicate trade-offs, and identify opportunities for continuous improvement.
Technical Innovation: Contribute to the evolution of engineering practices, proactively resolve complex technical challenges, and recommend improvements that enhance performance, reliability, and business value.
