Sr Principal SW Development Engineer

We are looking for experienced individuals who are well versed in architecting software solutions in an embedded system environment.
The candidate will be responsible for architecting, designing, developing and testing mission critical software components deployed into Nokia's Optical pluggable devices. The position requires deep knowledge in system design and architecture. A general understanding of RTOS, multi threaded operating systems and hand-on experience is solution development in embedded devices is a must.

=> Own end-to-end embedded architecture and solutions for Optical pluggable devices — from requirements and trade studies through hardware selection, software layering, interfaces, and release readiness.

=> Define system architecture and implement solutions (hands-on) across MCUs, RTOS or bare-metal stacks, drivers, middleware, power management, boot/OTA, and security (secure boot, crypto, threat modeling).

=> Partner with hardware, architecture and manufacturing teams to align schematics, data-sheets, analyze scope traces/logic analyzers, and validate architecture assumptions on real hardware.
 

=> Establish architecture standards and patterns — coding guidelines, HAL/BSP structure, reusable platform layers, documentation, and design reviews — so multiple teams can build consistently on shared platforms.

=> Lead technical decisions on complex trade-offs (cost vs. performance vs. power vs. time-to-market), document rationale, and present options clearly to engineering leadership and product stakeholders.
 

=> Drive quality and reliability for embedded products: debug strategy, diagnostics, failure analysis, environmental/stress considerations, and compliance with relevant standards (e.g. functional safety, EMC, industry-specific regulations where applicable).
 

=> Mentor development and test engineers - guide design reviews, unblock critical issues, and raise the team’s skill level

=> BS/MS in Computer Science/Electronics/Electrical with experience in embedded software development
=> Minimum 15+ years of experience in embedded systems design and development
=> A deep understanding of RTOS, multi threaded software systems and operating system concepts is required.
=> Knowledge and work experience in OTN standards and Optical devices is preferred.
=> Excellent analytical and troubleshooting skills are critical to this position
=> Experience in architectural leadership is expected
=> Well versed in object orient design philosophy and design patterns
=> Excellent communication and collaboration skills needed
