We are looking for an experienced Senior Software Engineer to build the calibration systems software for advanced electron microscope columns.

The rol e

You will own the architecture, design, and implementation of software that combines scientific computing, image processing, and distributed systems to enable fully automated calibration workflows - working at the intersection of software engineering, physics, and real laboratory hardware, under stringent performance requirements. The team is part of the R&D department

behind a major new product, developing the next generation of software and algorithm solutions that will power Applied Materials' metrology and inspection systems.

What you'll be doing:

• Stay deeply hands-on while owning project-level architecture for complex, stateful calibration workflows.
• Build end-to-end, full-stack services - from concurrent, iterative hardware control loops up to the operator-facing UI.
• Own algorithms end to end - research, design, implement, validate, document, optimize - across numerical methods, computer vision (registration, pattern matching, tracking), and performance-critical real-time image processing.
• Apply data science methods to real measurement data: design experiments, analyze results, quantify system performance with sound metrics.
• Build and evolve the AI-specific infrastructure of our physics-informed SDLC harness-agents, tools, context and evaluation pipelines.
• Develop hardware simulation and monitoring tools that support the team algorithm development and automated testing.
• Work closely with physicists to validate and refine calibration workflows and algorithms, and with Product, Design, and other R&D teams to ship them.

What you should have:

• 5+ years of professional software development
• 2+ years of R&D experience (algorithms / ML), including end-to-end ownership of meaningful features and projects.
• Deep concurrency expertise: designing concurrent execution models, parallelism, and multi-threaded dispatchers - and reasoning about their failure modes, tradeoffs, and performance under load.
• Strong system design: microservices and distributed systems, API design, message queues or event streaming (delivery semantics, ordering, failure handling).
• Numerical algorithms and optimization, image processing fundamentals, and familiarity with hardware control or instrumentation software.
• AI engineering: hands-on experience building with LLMs and agents - prompt and context engineering, tool calling, retrieval, evaluation - and a genuine drive to stay current.
• Solid engineering practices: e2e, regression, and automated testing, code review, CI/CD, virtualization (Docker).
• A product mindset - you understand customer needs and business impact.
• B.Sc. in Computer Science, Engineering, or a related field, or equivalent industry experience. Preferred backgrounds: computational physics, applied mathematics, image processing, optics, microscopy, signal processing, numerical analysis.

Nice to have:

• M.Sc. in CS, Software Engineering, EE, or a related field.
• A proven track record of excellence - academic, military, or professional honors, awards, or recognition for outstanding achievements.
• Electron microscopy or semiconductor equipment.
• Experience with advanced performance profiling and optimization.
• Experience with advanced concurrency models in another backend language (C++, Java, Kotlin, Go, Rust).

Technology stack: Our current R&D-phase stack — representative, not a checklist.

• APIs: FastAPI, Uvicorn, Pydantic, WebSockets.
• Algorithms: NumPy, SciPy, scikit-image, Matplotlib, Pillow.
• Hardware: pyserial, cffi, vendor device SDKs.
• Backend: SQLAlchemy, InfluxDB.
• Frontend: Dash, Plotly, PySide6, qasync.
• AI Provider: Anthropic / OpenAI.
• Testing and tooling: pytest (asyncio, mock, benchmark, coverage), mypy, Docker, Git.

Who we are: Applied Materials Israel is home to the Process Diagnostics and Control business unit (PDC).

Based in Rehovot, we develop, manufacture, and market cutting-edge machine learning and computer vision-based metrology and inspection products that are essential elements in wafer fabrication. By playing a significant role in enabling the production of the next generation of microchips, our expertise enables our customers to transform possibilities into reality.
