Senior Software Engineer - US-CA-Calabasas, United States
$129,450 - $215,740 USD yearly
Originally posted 28 August 2026 by the employer.
Advance the core architecture of a semiconductor design platform optimized for 3D Heterogeneous Integration.
About the role
As a Senior Software Engineer, you will advance the core architecture of a semiconductor design platform, expanding data representations, system-level APIs, and high-performance execution engines. This role focuses on complex 3D Heterogeneous Integration (3DHI) and programmatic workflows, partnering with domain experts across physical layout, schematic verification, and simulation.
What you'll do
- Drive technical decisions, platform design, and architectural evolution for core packaging engines.
- Design scalable APIs, data-exchange layers, and execution pipelines for code-first design flows.
- Architect extensible, decoupled integration interfaces for interoperability with internal solvers and third-party simulation tools.
- Optimize high-throughput runtime engines for automated design-space exploration and batch execution.
- Develop robust validation loops and constraint-checking mechanisms to ensure designs satisfy physical and manufacturability requirements.
- Partner with domain specialists, systems leads, and engineering teams to establish design standards and review complex codebases.
What you'll need
- Bachelor’s, Master’s, or Ph.D. in Computer Science, Electrical Engineering, Computer Engineering or related technical field.
- 8+ years of software development experience, including 2+ years in software architecture.
- Strong expertise in C++ and/or Rust.
- Demonstrated experience architecting complex data structures for large-scale engineering applications.
- Strong background in building low-latency, high-throughput backend services, or multi-threaded/concurrent data engines.
- Demonstrated ability to drive consensus on complex technical design trade-offs, author clear architecture specifications, and guide large feature initiatives.
- Deep commitment to software quality, including automated test frameworks, deterministic build environments, CI/CD pipelines, and rigorous code-review practices.
Nice to have
- Strong proficiency in Python, with experience in C++/Rust integration.
- Experience designing validation frameworks, rule-checking engines, and telemetry to track state changes and catch constraint violations early.
- Familiarity with programmatic interaction patterns or multi-agent execution frameworks.
- Familiarity with electronic design and packaging abstractions, such as schematic connectivity, physical layout hierarchies, netlisting, or multi-die 2.5D/3D packaging concepts.
