Firmware Validation Engineer

The Role

We are seeking a Firmware Validation Engineer with a builder’s mindset. While your primary mission is to ensure the integrity of our optical modules through rigorous testing, you won't just be finding bugs - you'll be invited to help squash them. This role offers the unique opportunity to contribute directly to firmware development, making it ideal for a validation expert who wants to keep their coding skills sharp and influence the product architecture.

Key Responsibilities

  • Test Strategy & Design:  Analyze product requirements and functional specifications to design comprehensive test plans and detailed test cases for firmware validation.
  • Development Contribution:  Collaborate with the design team to write and optimize firmware code, implement bug fixes, and develop new features for optical control.
  • Test Case Architecture:  Transform complex technical requirements into sophisticated Python-based automation frameworks.
  • Cross-Functional Debugging:  Lead root-cause analysis sessions, bridging the gap between hardware, firmware, and optical physics.
  • Agile Execution:  Rapidly pivot between high-priority tasks in a fast-paced environment where requirements and hardware revisions evolve quickly.

Required Qualifications

  • Experience:  5+ years in firmware validation or embedded software development.
  • Technical Core:  Bachelor’s degree in EE or CE  and a penchant for solving complex technical problems.
  • Scripting & Tooling:  Expert-level Python  skills for automation. Experience with C/C++ is required for your contributions to the firmware codebase.
  • Lab Skills:  Hands-on experience with hardware-in-the-loop (HIL) testing and standard lab equipment (Oscilloscopes, Optical Spectrum Analyzers, BERTs).
  • Mindset:  A "fail fast, learn faster" attitude. You must be highly flexible  and thrive in a high-pressure, rapid-growth setting.
  • Automation:  Proven track record of building automated test benches from scratch to validate hardware/firmware interactions.

Preferred Qualifications

Optics:  Familiarity with Silicon Photonics  or Optical Transceivers  is highly desirable.

MCU:  Prior experience with STM32 family of microcontrollers is a plus.
