Job Title: C++ Software Engineer (Contractor) – Linux OS

Location: Santa Clara, CA onsite

Long Term Contract

Role Summary

We are seeking an experienced Linux Software Engineer (Contractor) to work on a wafer inspection system, with a primary focus on integrating application software with Linux device drivers.

This role does not involve Linux kernel or device driver development. Instead, the engineer will focus on Linux user-space C/C++ development, improving software architecture, robustness, and maintainability while integrating with existing drivers.

Key Responsibilities

• Review and analyze existing Linux C++ application code flow, architecture, and interaction with Linux device drivers.
• Integrate and maintain application-level interfaces with existing Linux device drivers.
• Understand and reassess legacy assumptions related to driver interaction, sequencing, timing, data flow, and error handling.
• Refactor and enhance user-space C/C++ software to improve clarity, scalability, and long-term maintainability.
• Make design and architectural improvements to existing software components.
• Work on complex issues where system behavior and data require deep technical analysis.
• Ensure designs, code, and unit tests are robust, scalable, and future-proof.
• Debug and resolve issues at the Linux user-space / device-driver interface boundary.
• Collaborate with system, driver, and application teams to validate end-to-end functionality.
• Support integration testing, regression testing, and lab bring-up activities.

Required Technical Skills (Must Have)

• Strong experience with Linux user-space software development.
• Proficiency in C / C++ programming.
• Solid understanding of Linux OS fundamentals (processes, memory, threading, I/O).
• Hands-on experience integrating applications with Linux device drivers.
• Familiarity with user-kernel interaction mechanisms such as:
• ioctl
• mmap
• shared memory
• sysfs
• Strong debugging skills using GDB, logs, and Linux diagnostic tools.
• Experience refactoring legacy code and porting functionality across codebases.
