Python Phd Hpc information

What are the key skills and qualifications needed to thrive as a Python PhD HPC (High Performance Computing) specialist, and why are they important?

To excel as a Python PhD HPC specialist, you need advanced knowledge of Python programming, parallel computing concepts, and a doctoral degree in a computationally intensive field. Familiarity with HPC clusters, job schedulers like SLURM, and libraries such as NumPy, SciPy, and MPI for Python is typically required. Strong analytical thinking, problem-solving, and collaboration skills set candidates apart in this role. These competencies ensure efficient development, optimization, and deployment of large-scale computational models that drive scientific research and innovation.

What are the typical challenges faced by a Python PhD HPC professional when working on large-scale computational projects?

Professionals in a Python PhD HPC role often encounter challenges related to optimizing Python code for high-performance computing environments, particularly when scaling computations across multiple nodes or clusters. Managing memory usage, debugging parallel code, and ensuring compatibility with various HPC libraries and frameworks are common hurdles. Additionally, effective collaboration with interdisciplinary teams—such as domain scientists, system administrators, and data engineers—is crucial for project success. Staying updated with advancements in both Python and HPC technologies also requires ongoing learning and adaptability.

What is a Python PhD HPC specialist?

A Python PhD HPC specialist is a professional with a doctoral degree who uses the Python programming language to develop and optimize high-performance computing (HPC) applications. These specialists often work on complex scientific or engineering problems that require significant computational resources, such as simulations, data analysis, or machine learning at scale. They possess deep expertise in both Python programming and HPC environments, including parallel computing, distributed systems, and cluster management. Their work often bridges the gap between theoretical research and practical implementation on supercomputers or large compute clusters.

Job description

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world's first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.
Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!
If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.
Lightmatter is (re)inventing the future of computing with light!
We are hiring a Photonics PDK Modeling Engineer to join our team. In this role, you will lead the development of our internal Process Design Kit (PDK). You will act as the architect of our component library, bridging the gap between physical device physics and system-level simulation. You will develop robust compact models for active and passive components, ensuring that our simulation environment accurately predicts the behavior of our physical layouts. You will work heavily in Python, applying software engineering rigor to the challenges of photonic hardware design.
Responsibilities
  • Develop and maintain a library of pcells using Python-based layout frameworks. Ensure strict synchronization between physical layout, logical netlists, and behavioral models.
  • Create and verify behavioral compact models for passive and active devices
  • Simulation Infrastructure: Build automated workflows that extract parameters from electromagnetic solvers (FDTD/FEM) and package them into the PDK for circuit-level simulation.
  • Model-Hardware Correlation: Validate simulation models against lab measurements. Perform data fitting and statistical analysis to align model parameters with real-world silicon performance.
  • Automated Verification: Implement regression testing and Continuous Integration (CI) pipelines to ensure PDK updates do not break legacy designs or connectivity logic.
  • Netlist & Connectivity: Own the logic for netlist extraction, ensuring that the connectivity graph generated by the code perfectly matches the physical intent.
Qualifications
  • Master's +5 years experience or PhD +3 years experience in Electrical Engineering, Photonics, Physics, or related field.
  • Deep understanding of photonic device physics and experience in device simulation.
  • Experience building behavioral models for circuit simulators (e.g., Lumerical INTERCONNECT, Cadence, Synopsys OptSim, or custom Python solvers).
  • Experienced in Python for modeling, automation, and data analysis. Comfortable with object-oriented programming and scientific libraries (NumPy, SciPy).
  • Python based layout experience.
Preferred Qualifications
  • Familiarity with GDSFactory, OptoCompiler or KLayout Python scripting.
  • Experience with Python-native circuit simulation ecosystems (e.g., SAX, Photontorch, Simphony).
  • Experience with Git version control, unit testing (pytest), and CI/CD workflows.
  • Prior experience in performing physical layout using foundry-provided process design kits (PDKs), adhering to specific design rules and constraints.
  • Experience in taping out and testing large-scale photonic integrated circuits, including familiarity with relevant testing equipment and methodologies.
  • Experience doing inverse design
  • Possess strong project execution skills, demonstrating the ability to effectively manage multiple design priorities, adhere to project timelines, and meet critical milestones.

We offer competitive compensation. The base salary range for this role determined based on location, experience, educational background, and market data.
Salary Range: total compensation goes beyond base salary, it also includes a new hire equity grant, annual performance-based equity, and other rewards that recognize your impact and contribution.
$187,000-$220,000 USD
Benefits
  • Comprehensive Health Care Plan (Medical, Dental & Vision)
  • Retirement Savings Matching Program
  • Life Insurance (Basic, Voluntary & AD&D)
  • Generous Time Off (Vacation, Sick & Public Holidays)
  • Paid Family Leave
  • Short Term & Long Term Disability
  • Training & Development
  • Commuter Benefits
  • Flexible, hybrid workplace model
  • Equity grants (applicable to full-time employees)
