Additionally, the candidate will be help us enhance our data management, frontend-backend API unification, and cloud integration. Key Responsibilities Contribute to general software development efforts, such as API unification, simulation data management (e.g., caching, syncing, storage), and scripting improvements. Collaborate with EM and infrastructure teams to implement simulation-specific solutions, including enhancements to back-end/scheduler integrations and Python front-end functionality. Improve our task pipelines through an innovative design for a web API in a multi-physical simulation context. Develop and maintain hybrid cloud compute and storage solutions, integrating on-premise HPC systems with modern cloud platforms. Optimize and manage high-performance computing clusters equipped with high-speed interconnects. Requirements Education: Bachelor’s degree or higher in computer science or computer engineering. Technical Skills: Proficiency in Python, C++, and Java, with experience in distributed computing environments (e.g., MPI). Familiarity with backend API development, documentation, packaging, and deployment. Understanding of HPC computing, system administration, and networking. Experience compiling and optimizing C++ source code. Expertise in cloud computing and storage solutions. Proficiency in Linux operating systems, software deployment (e.g., Ansible), and backend security. Experience with containerization and orchestration tools (e.g., Docker, Kubernetes, Swarm). Innovative Mindset: Ability to learn quickly, adapt to new challenges, and innovate in a fast-paced startup environment. Bonus Skills: Familiarity with electromagnetic physics simulations Knowledge of memory, CPU, and GPU resource optimization. Familiarity with simulation-specific tooling and workflows. Understanding of simulation GUI and scripting interfaces. Example Projects Work with the wider team to merge code into a single repo and then build CI/CD that enforces best-practices, like protecting the main branch Implement docker container usage across the developer workflow, from development to deployment including automated, parameterized image building for on-premise customers Build and deploy a desktop configuration with GUI that connects to a network simulation service and includes licensing controls Track, monitor, and improve the end-to-end latency of simulation runs across all user traffic Manage the sizing and configuration of the high-performance computing cluster comprised of CPUs and GPUs, and track metrics like utilization and performance Collaborate closely with EM team members on the design and optimization of multi-physics simulation workflows, including using frameworks like Slurm and Dask and redesigning our web API Join Us By joining Flexcompute, you’ll be at the heart of a movement set to redefine the engineering simulation industry. You will play a key role in shaping the future, where our innovations in simulation technology pave the way for groundbreaking advancements. We are committed to fostering an innovative and collaborative culture where boundaries of possibility are re-imagined, driven by creativity, expertise, and a shared vision of transforming the technological landscape.
