About The Position

The Senior Software Engineer will design, develop, and maintain backend libraries and services that transform diverse data formats into a common, reusable schema consumed by multiple applications across the organization. This is a hands‑on technical role focused primarily on Java development, with secondary responsibility for Python‑based components where needed. There is no UI work; the emphasis is on building robust libraries and integration services that can reliably ingest, interpret, and convert constantly changing data sources into a standardized internal model. In addition to core development responsibilities, this role includes a system administration component. The engineer will help manage and optimize MongoDB services, work within a Linux ecosystem, and perform operational tasks such as upgrading servers, installing RPMs, monitoring services, and troubleshooting environment issues. Key responsibilities include designing and implementing data ingestion and transformation logic, creating and maintaining shared libraries for common data formats, ensuring performance and scalability, and contributing to architectural decisions around data modeling and integration patterns. The role also involves collaborating through modern development practices, including Git‑based source control, code reviews, and continuous improvement of development workflows. The ideal candidate has deep experience in Java (and familiarity with Python), a strong understanding of working with varied data formats (e.g., JSON, XML, CSV, and custom structures), and practical experience administering Linux‑based systems and MongoDB in production environments. Strong problem‑solving skills, attention to detail, and a willingness to engage in both development and operational tasks are critical for success in this role.
