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:

• 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.
• Optimize I/O operations for CPU/GPU-based workflows to minimize bottlenecks.
• Implement caching, compression, and other strategies to enhance performance.
• 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.
• Develop and execute test cases to validate module performance and reliability under various load conditions.
• Conduct benchmarking to ensure scalability across different hardware configurations.
• Document the architecture, APIs, and usage guidelines for the data service module.
• Provide technical support to the development and visualization teams for data integration.

Requirements:

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related fields.
• 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.
• 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
• Might be a plus: knowledge of at least one orchestration and scheduling tool, for example, Airflow, Prefect, Dagster, etc.
• 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.
