Job Summary
Job summary
We are looking for an engineer to design develop and integrate software for next-generation optical network elements Optical Line Systems optical pluggables and coherent optical systems.
The role covers embedded software Device Abstraction Layer Hardware Abstraction Layer hardware-interface software optical line system control pluggable module management telemetry management plane interfaces and optical-domain software integration.
The engineer will collaborate with optics hardware firmware software system architecture and test teams to build reliable software for EDFAs Raman amplifiers ROADMs WSS photodiodes sensors coherent modems and optical pluggables.
Key responsibilities
Develop embedded and system software using the JD programming reference: MATLAB C/C where relevant; C for OLS software development
Build Device Abstraction Layer and Hardware Abstraction Layer components for I2C SPI MDIO EEPROM sensors pluggables and optical components.
Develop EDFA/Raman amplifier control gain control Automatic Power Control Automatic Gain Control power balancing alarm monitoring safety shutdown and protection switching logic.
Support ROADM and line-system functions including spectrum allocation path computation flexgrid provisioning and real-time reconfiguration.
Develop optical pluggable software for CMIS/SFF interface handling DDM/DOM monitoring module state handling firmware upgrade and power class management.
Support optical topology modelling path computation impairment-aware routing and optical power management algorithms.
Understand coherent optical modulation and performance concepts such as QPSK DP-QPSK BPSK QAM variants baud rate spectral efficiency BER and FEC.
Validate optical performance using Optical Spectrum Analyzer optical power meters oscilloscopes VOA optical switches wave shapers tunable lasers and traffic generators.
Minimum qualifications
Either Optical Line System or Optical Pluggable is Mandatory
Bachelors or Masters 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
