Thanks for your interest in working on our team!

Welcome!

Our continued growth is creating exciting opportunities - and we're looking for talented engineers to join our team. Explore our current openings, apply to the roles that best match your skills, and stay informed about your application status and future opportunities.

We appreciate your interest in joining our team!

About the Role

The Senior Software/Firmware Engineer will design, develop, and test embedded software for Reconfigurable Optical Add-Drop Multiplexers (ROADMs). You will collaborate closely with optical, hardware, and test engineers to deliver high-quality, production-grade firmware for next-generation optical networking systems.

Key Responsibilities

  • Design, develop, and integrate modern C/C++ embedded software running on Linux and real-time operating systems (RTOS) such as FreeRTOS.
  • Own the complete software development lifecycle - from requirements and architecture through implementation, testing, debugging, and deployment.
  • Develop and maintain device drivers for fiber-optic components (e.g., WSS, OCM) and other hardware subsystems.
  • Collaborate with hardware teams on schematic reviews, hardware design input, and board bring-up.
  • Partner cross-functionally with optical, hardware, and test engineers in an Agile environment to meet product milestones and quality goals.
  • Develop and maintain unit tests, automation scripts, and test frameworks to verify and validate firmware functionality.

Basic Qualifications

  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
  • 10+ years of experience in embedded software or firmware development, preferably in telecommunications or networking.
  • Strong proficiency in modern C/C++, including adherence to C++ best practices and coding standards.
  • Experience with RTOS, low-level debugging, and hardware/software integration.
  • Solid understanding of embedded communication protocols (SPI, IC, UART) and hands-on experience developing and debugging device drivers.
  • Familiarity with ARM or other microcontroller architectures.
  • Proficient with Git and collaborative development workflows (branching, reviews, CI).
  • Skilled in reading schematics, using oscilloscopes, and troubleshooting embedded systems.
  • Experience participating in code reviews, testing, and documentation to ensure high-quality deliverables.
  • Excellent analytical, problem-solving, and communication skills.
  • Demonstrated ability to work effectively with cross-functional teams, including QA, product management, and manufacturing.
  • Commitment to continuous learning and staying current with modern C++ and emerging embedded technologies.

Nice to Have

  • Experience developing device drivers for ASICs or FPGAs.
  • Hands-on experience with CMake and scripting languages (Bash, Python, Ruby, or Perl).
  • Experience implementing CI/CD pipelines for embedded platforms.
  • Familiarity with Agile/Scrum methodologies.
  • Understanding of optical networking technologies such as OTN, Gigabit Ethernet, and related transport systems.
  • Proficiency in using oscilloscopes, logic analyzers, and diagnostic tools for system validation and debugging.

Requirements & Work Environment

  • Full-time, permanent position (40 hours per week).
  • Hybrid role - in-office Tuesday through Thursday; remote Monday and Friday.
  • Primary location: Norcross, GA, USA.
  • Must be authorized to work in the United States.
  • Energetic, collaborative, and eager to work with a diverse team.
  • Positive attitude, adaptability, and a genuine desire to learn, innovate, and excel.

Why Join Us

Join a team that's shaping the future of optical networking. We offer a collaborative environment, opportunities for professional growth, and the chance to work with cutting-edge technologies that power global communications.
