Senior Principal Software Development Engineer

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

Job summary

Jobtailor in India is seeking an experienced Principal Embedded Architect to own end-to-end architecture for Optical pluggable devices, covering requirements, hardware-software interfaces, and release readiness.

You will define system architectures across MCUs, RTOS or bare-metal stacks, and secure boot/OTA, while mentoring engineers and driving cross-functional collaboration with hardware, manufacturing and product teams.

Qualifications

• 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

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 (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.
