Software Development Engineer — PDK/ Foundrykits SW Automation Engineer- EM, Thermal, Spice, Spectre simulations

We are looking for a Software Development Engineer to design and build the next

generation electromagnetic (EM) simulation, Thermal, Spice, Spectre and RF/microwave

design automation tools and build & interfaces to & fro for for semiconductor foundries and

customers. You will work on the software that powers full-wave EM solvers, Thermal

simulation engines, Spice & Spectre simulators, layout-driven extraction flows, and the

automation pipelines that turn foundry technology data (ITF/LTD, layermaps, tech files) and

physical layout (GDS) into accurate S-parameter models.

Required Skills

 Strong programming skills in C++ (Modern C++ preferred) and/or Python, with solid

understanding of data structures, algorithms, and software design principles.

 Good understanding of Object-Oriented Design, Design Patterns, and Software

Engineering principles.

 Solid foundation in numerical methods and linear algebra (matrix solvers, sparse

systems, iterative methods, floating-point numerics).

 Experience developing on Linux and/or Windows, with familiarity in build systems

(CMake), version control (Git), and CI/CD workflows.

 Strong problem-solving, debugging, and analytical skills.

 Understanding of software security, testing, and code quality practices.

 Knowledge & insight of TSMC iRCX file format.

 Working knowledge of AES and other encryption method and implementations.

 Basic understanding of high frequency electronic design, its process

(PCB/PKG/RFIC/MMIC) and key components.

 Understanding electromagnetic / RF / microwave theory (Maxwell’s equations,

transmission lines, S-parameters, antenna parameters, signal & power integrity).

Preferred Skills

 Familiarity with electromagnetic simulation tools

 Knowledge of computational electromagnetics (FEM, MoM, FDTD, integral-equation

methods) or other physics-based simulation techniques.

 Familiarity with EDA tools and flows (e.g., ADS, RFPro, EMPro, Momentum, HFSS,

Heatwave, IcePak, Thermal simulators (CAE/ EDA), Cadence, or similar) and technology

data formats (GDS, ITF, LTD, layermap, tech files, Touchstone/SnP).

 Experience building automation frameworks, scripting APIs, or plugin architectures for

simulation tools.

 Experience using AI-assisted development tools (e.g., GitHub Copilot, ChatGPT,

Claude, Cursor) and understanding of AI/LLM concepts, prompt engineering, and

agentic workflows.

 Contributions to open-source scientific/numerical software.
