Minimum qualifications

• Bachelor’s or Master’s degree in Electronics, Electrical Engineering, Computer Science, Telecommunications, Photonics, Optics, Applied Physics or related discipline.

• 5+ years for engineer roles, 8+ years for senior roles, in embedded software, telecom software, NE software, firmware, Linux drivers.

• Hands-on experience in at least two core technical areas: programming/system software, Linux/device interface, hardware-interface protocols, optical line system or optical pluggables.

• At least one optical pillar is mandatory: Optical Line System OR Optical Pluggables.

Preferred coherent optics exposure

• Constellation analysis and modulation-format selection.

• ADC/DAC awareness, sampling rate concepts and ENOB awareness where relevant.

• Pre-FEC and post-FEC BER interpretation.

• OSNR sensitivity, reach versus capacity trade-off and modulation impact on line-system design.

• Coherent DSP awareness including equalisation, carrier recovery and impairment compensation at conceptual level.
