Senior HPC Data Engineer

About the Role We are looking for an experienced Data Service Module Engineer to develop and deploy the data service module for the HPC modeling project. This role focuses on implementing high-performance data storage and retrieval systems using HDF5 or similar, with parallel and concurrent I/O capabilities. The ideal candidate will have expertise in designing scalable data services optimized for HPC or distributed workflows, ensuring low latency and high throughput. Key Responsibilities Module Development and Deployment: Design and implement the data service module using HDF5 for efficient data storage and retrieval. Develop parallel and concurrent I/O mechanisms to optimize performance for large-scale datasets. Ensure the module is tightly integrated with HPC and visualization workflows. Performance Optimization Optimize I/O operations for CPU/GPU-based workflows to minimize bottlenecks. Implement caching, compression, and other strategies to enhance performance. Data Management Design data structures and schemas suitable for storing 3D grid data and other simulation outputs. Ensure data integrity and consistency during concurrent read/write operations. Testing and Validation Develop and execute test cases to validate module performance and reliability under various load conditions. Conduct benchmarking to ensure scalability across different hardware configurations. Documentation and Support Document the architecture, APIs, and usage guidelines for the data service module. Provide technical support to the development and visualization teams for data integration. Qualifications Education Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related fields. Experience 3+ years of experience in developing and deploying data services for HPC or similar systems. Proven expertise with HDF5 or similar, in parallel I/O operations. Equivalent experience in distributed systems is also applicable. Technical Skills Programming: Strong proficiency in (at least one): C++, Python, GoLang, or Fortran. HDF5 Expertise: In-depth knowledge of HDF5 APIs and advanced features like parallel HDF5. Parallel I/O: Experience with MPI I/O, POSIX I/O, or similar frameworks for concurrent/parallel data access. Performance Optimization: Skills in profiling and optimizing I/O operations for large datasets. Proficiency in SQL and experience with any RDMS Knowledge of at least one orchestration and scheduling tool (e.g., Airflow, Prefect, Dagster) is a plus. Soft Skills Strong problem-solving skills and ability to work in a multidisciplinary team. Excellent communication skills for cross-team collaboration and documentation. Preferred Qualifications Familiarity with data formats used in scientific computing, 3D visualization, and simulation workflows.
