Lead root-cause analysis across hardware, firmware, and optical physics; build automated test benches
5+ years in firmware validation or embedded software
Bachelor’s in EE or CE; strong problem-solving ability
Expert Python for automation; C/C++ for firmware contributions
Hands-on HIL testing and standard lab equipment experience
Agile mindset; ability to work under rapid-growth, high-pressure conditions
Familiarity with Silicon Photonics or Optical Transceivers
Experience with STM32 microcontrollers
Location & work type: Not specified in the provided details
The Role We are seeking a Senior 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.
What Makes You a Good Fit? You don't just follow a checklist; you anticipate where the system might fail and have the technical chops to suggest—or implement—the solution. You are comfortable with ambiguity and can re-prioritize your day as project needs shift.
Why Join Us? This isn't a siloed role. You will have a seat at the table during the entire development lifecycle, from initial concept to final module deployment, working at the cutting edge of optical interconnect technology.
