  • Support reliability testing initiatives to validate long-term performance under real-world conditions.
  • Diagnose and resolve issues in embedded systems using tools such as GDB, JTAG, and logic analyzers.
  • Engage with customers to understand requirements and translate them into technical specifications for future product iterations.

What You Bring

  • Bachelor’s degree in Computer Science, Electrical Engineering, Robotics, or a related field, plus at least two years of relevant experience (or equivalent practical experience).
  • Proven experience developing firmware in C, C++, Python, and MongoDB, with strong fluency in Linux-based development environments.
  • Familiarity with ASIC firmware reliability practices and datacenter management standards such as CMIS, OpenBMC, and DMTF.
  • Hands-on experience with Git and CMake for software build and project management workflows.
  • Strong grasp of embedded system communication protocols, peripherals, and hardware-software integration principles.
  • Experience collecting, analyzing, and reporting technical data to inform design decisions.

Nice to Have

  • Experience with Snowflake for data reporting and analytics.
  • Background in optical component characterization and test methodologies.
  • Development experience with optical transceivers or similar high-speed communication systems.
  • Proficiency with debugging tools including logic analyzers, JTAG, and GDB.

Environment & Culture

You'll be part of a team pushing the boundaries of computing using light-based technologies. The environment values deep technical expertise, collaboration, and solving hard problems with real-world impact. You’ll work alongside leading scientists and engineers who are redefining what’s possible in high-performance computing.

Work Model

This role operates under a flexible hybrid model, allowing for a balance between in-person collaboration and remote work.

Benefits

  • Comprehensive health coverage including medical, dental, and vision
  • Retirement savings with employer match
  • Life and disability insurance (short- and long-term)
  • Generous paid time off and family leave policies
  • Commuter benefits and professional development support
  • Equity grants for full-time employees, with annual performance-based refreshes

Compensation

Base salary range: $105,000 — $112,000 CAD. In addition to a competitive salary, new hires receive an equity grant with potential for annual performance-based equity adjustments. Total compensation includes recognition for impact and contributions beyond base pay.
