Senior Principal Software Development Engineer

Jobtailor; Bengaluru; On-site; INR 4,000,000 - 7,000,000; Full time

Job summary

Jobtailor in Bengaluru seeks a Senior Embedded Architect to own end-to-end embedded architecture for optical pluggable devices. You will drive requirements, hardware-software interfaces, and release readiness, collaborating with hardware, architecture and manufacturing teams.

You will define system architecture across MCUs, RTOS or bare-metal stacks, drivers, power management, boot/OTA, and security, while guiding trade-offs and ensuring regulatory compliance.

Qualifications

• BS/MS in Computer Science/Electronics/Electrical with embedded software experience.
• Minimum 15+ years of experience in embedded systems design.
• Deep understanding of RTOS, multi-threaded software systems and OS concepts.
• Knowledge and work experience in OTN standards and Optical devices preferred.
• Excellent analytical and troubleshooting skills.

Responsibilities

• 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.
• Partner with hardware, architecture and manufacturing teams to align schematics, datasheets, 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.
