• Collaborate with a global team of researchers and engineers in Hitachi Energy business units to identify and solve real-world challenges for our customers through expertise in software applications for Power systems.

• Propose, contribute to and lead research and development projects creating mathematical solvers for intense calculations leveraging HPC.

• Work with a multitude of technologies and stacks, for systems spanning from on premise edge device, embedded, single server up to the scalable cloud-based solutions.

• Evaluate feasibility and performance of 3rd party components for application in our products, such as GPU, TPU or other high performance computing technologies.

• Advise researchers on optimizing code for a target platform.

• Advise internal IT on optimal evolution of the company high-performance computing environment.

• Network in the company and actively distribute your knowledge and expertise.

• Provide consultancy in your field of expertise to our business units.

• Collaborate with local and global external partners including universities, open-source communities, startups and vendors.

• Disseminate your results in scientific publications, patent applications, and technical reports.

Your background

• Master’s or PhD degree in Computer Science, Software Engineering or in a related field.

• Ability to conduct all phases of a software project – conceptual work, architecture preparation, design, prototyping and verification.

• Able to analyze algorithms for computing, memory, communications bottlenecks.

• Familiar with modern cluster and GPU/TPU based HPC architectures on premises and in the cloud.

• Experience with SW libraries for using certain HPC architectures (CUDA, MPI,…) and distributed/virtualized systems.

• Know-how of modern design patterns, methodologies, programming languages, frameworks and stacks.

• Willingness to mix conceptual activities with hands‑on work.

• Ability to adapt to different team sizes – from single‑person studies to participation in large teams.

• Willingness to take an interdisciplinary approach, working with experts from domains away from own area of expertise.

• Experience that demonstrates your team-oriented, innovative, and strategic working styles.

• Fluency in English, both written and spoken.

In addition, the following skills would be beneficial for the role:

• Experience with large code bases.

• Experience with container and microservice architectures.
