Senior Python Developer

<h3>About the Role:</h3>

We are looking for a highly skilled Python Developer with a deep understanding of device-level programming, Linux systems, and hardware-software interfacing, particularly over USB. In this role, you will be responsible for building and optimizing software components that facilitate communication between the operating system and a variety of instruments and hardware devices.

You will play a crucial role in our product development lifecycle, particularly in the integration of complex instruments with software platforms, ensuring high performance, reliability, and usability of our solutions.

<h3>Key Responsibilities:</h3>

• Python Development in Linux:
  • Design, develop, and maintain Python applications for Linux-based environments.
  • Optimize Python scripts for performance and stability in low-level operations.
  • Ensure compliance with Linux system standards and best practices.
• Device Driver & USB Interface Development:
  • Build and integrate Python modules for USB-based device communication.
  • Create or wrap low-level USB drivers (e.g., using <code>pyusb</code>, <code>libusb</code>, <code>hidapi</code>, or custom interfaces).
  • Handle USB enumeration, control transfer, bulk/interrupt transfers, and driver registration.
  • Debug driver issues using tools like <code>usbmon</code>, <code>dmesg</code>, and Wireshark.
• Hardware/Instrument Interfacing:
  • Interface with various measurement instruments, sensors, controllers, and custom hardware using Python.
  • Implement communication protocols (USB, UART, RS232/485, GPIB, SPI, I2C) as required.
  • Develop reusable libraries/modules for instrument control, data acquisition, and diagnostics.
• Collaboration & Documentation:
  • Collaborate with hardware, firmware, and QA teams for seamless integration and testing.
  • Provide clear documentation for driver interfaces, APIs, communication flows, and setup procedures.
  • Participate in code reviews and provide constructive feedback to peers.

<h3>Required Skills & Experience:</h3>

• 3+ years of experience in Python development, with strong expertise in system-level programming.
• Solid hands-on experience with Python on Linux (e.g., file I/O, multiprocessing, subprocess management, logging).
• Proven expertise in device driver development (especially user-space drivers in Python).
• Strong working knowledge of USB communication, endpoints, and class protocols (CDC, HID, etc.).
• Experience with hardware instrumentation, including interfacing and controlling physical devices.
• Familiarity with pySerial, pyUSB, libusb, pyVISA, or similar libraries.
• Ability to interpret hardware specifications and datasheets to design compatible software interfaces.
• Strong debugging and troubleshooting skills, using tools like <code>strace</code>, <code>gdb</code>, <code>dmesg</code>, and logic analyzers.

<h3>Nice to Have (Bonus Points):</h3>

• Experience with C/C++ for lower-level driver development or performance-critical components.
• Background in test automation or hardware-in-the-loop (HIL) testing.
• Experience with real-time systems or time-sensitive data acquisition applications.
• Knowledge of instrument control protocols like SCPI or Modbus.
• Familiarity with embedded Linux development (e.g., Yocto, Buildroot) or Raspberry Pi-based deployments.

<h3>Educational Qualifications:</h3>

• Bachelor’s or Master’s Degree in Computer Science, Electronics, Electrical Engineering, or a related field.

<h3>Why Join Us?</h3>

• Work on cutting-edge systems that bridge hardware and software.
• Collaborate with an expert team across electronics, firmware, and data systems.
• Flexible work environment with opportunities for innovation and ownership.
• Get hands-on exposure to real-world device integration challenges and industrial-grade instrumentation.
