About the role

Key responsibilities & impact

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
