Optical Line System / Optical Pluggable NE Software Development Engineer

Client: Nokia



Location: Anywhere in USA



Work Arrangement: Remote; travel may be required based on client location



Employment Type: Full-Time



Client Interview: Yes Job Summary

Nokia is seeking an experienced Optical Line System / Optical Pluggable NE Software Development Engineer to design, develop, and integrate software for next-generation optical network elements, optical line systems, optical pluggables, and coherent optical systems.

The role focuses on embedded and system software, Device Abstraction Layer (DAL), Hardware Abstraction Layer (HAL), 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 develop reliable software for EDFAs, Raman amplifiers, ROADMs, WSS, photodiodes, sensors, coherent modems, and optical pluggables.

• Develop embedded and system software using C/C++ ; MATLAB exposure is a plus for modeling and analysis.

• Develop Device Abstraction Layer and Hardware Abstraction Layer components.

• Implement and integrate hardware interfaces including I2C, SPI, MDIO, EEPROM , and applicable PCIe interfaces.

• Develop software for optical components, sensors, transceivers, and pluggable modules.

• Develop EDFA/Raman amplifier control , gain control, Automatic Power Control (APC), Automatic Gain Control (AGC), power balancing, alarm monitoring, safety shutdown, and protection-switching logic.

• Support ROADM and optical line-system functions , including spectrum allocation, path computation, flex-grid provisioning, and real-time reconfiguration.

• Develop optical pluggable management software supporting CMIS/SFF , DDM/DOM monitoring, module state management, firmware upgrades, and power-class management.

• Support optical topology modeling, path computation, impairment-aware routing, and optical power-management algorithms.

• Apply knowledge of coherent optical technologies including QPSK, DP-QPSK, BPSK, 8QAM, 16QAM, 32QAM, 64QAM , baud rate, spectral efficiency, BER, and FEC.

• Validate optical performance using equipment such as Optical Spectrum Analyzers, optical power meters, oscilloscopes, VOAs, optical switches, wave shapers, tunable lasers, and traffic generators .

• Collaborate with hardware, optics, firmware, system architecture, and QA/test teams.

• Troubleshoot software, hardware-interface, optical-domain, and network-element issues.

Programming

• Strong C/C++ development experience.

• MATLAB exposure is an advantage.

Embedded/System Software

• Experience with Embedded Linux .

• Experience developing drivers, user-space software, firmware, Device Abstraction Layer, Hardware Abstraction Layer, or network-element/system software.

Hardware Interfaces

• Hands-on experience with I2C, SPI, MDIO, EEPROM and/or PCIe.

• Experience accessing sensors and optical pluggables.
