Job Description
Senior Principal Engineer – Firmware (Ser Des & DSP)
Location: Bengaluru, India
Minimum Experience: 15+ years
Role Overview
We are seeking a Senior Principal Engineer for Engineering Company to lead firmware development for complex, high-performance Ser Des and DSP-based systems. This is a highly visible, hands-on leadership role where you will own firmware architecture, guide cross-functional teams, and drive products from early silicon bring-up through volume production. This role would require travel to the US/ Europe for upto 3-weeks per year.
This role requires deep, hands-on firmware experience with Ser Des & DSP systems.
Mandatory Experience (Must-Have)
- Hands-on firmware development for Ser Des & DSP systems (Mandatory)
- Experience with SERDES, IM-DD / Coherent DSP, Ethernet or PCIe PHYs, and Optical Module software
- Proven expertise in developing embedded C/C++ firmware tightly coupled with DSP hardware
- Strong experience debugging Ser Des/DSP-based systems on real hardware
- Experience leading firmware development for complex embedded products through production
Key Responsibilities
- Serve as technical and/or project lead for firmware development, guiding a team of 2–8 engineers
- Own architecture, design, development, and testing of embedded firmware controlling complex DSP hardware
- Drive complex HW/SW debug, identify root causes, and collaborate with hardware, validation, and customer teams
- Plan firmware milestones, execute sprint-based development, close defects, and deliver production-quality releases
- Translate complex system and standards specifications (MSA / OIF / CMIS) into clear internal documentation and design artifacts
- Mentor junior engineers and conduct design and code reviews
- Support post-silicon bring-up, field issues, and customer escalations
- Travel globally for product development and chip bring-up (~3 weeks per year)
Required Skills & Qualifications
- 15+ years of experience in memory-constrained embedded C/C++ firmware development
- Proven experience as a Technical Lead or Software Team Lead on embedded products through volume production
- Strong understanding of:
- Embedded So Cs and microcontroller architectures (RISC-V preferred)
- Memory-mapped hardware, GPIOs, ISRs, and low-level HW interfaces
- Excellent debugging skills on real hardware in lab environments
- Strong written and verbal communication skills in English
- Proficiency with Git, defect tracking tools (Jira or similar), and Linux development environments
Preferred / Nice-to-Have Skills
- Designing and debugging firmware state machines
- DSP fundamentals: BER, SNR, FFT, impulse & frequency response, histograms, sampling phase
- Experience with bare-metal, RTOS, device drivers, or Linux kernel
- Mixed-signal control systems (analog + digital, PID / feedback loops)
- Proficiency in Python for tooling, automation, or GUI development
- Familiarity with:
- Compiler toolchains (gcc / clang)
- FPGA emulation and DV simulation environments
- Verilog and digital verification flows
- Lab equipment such as oscilloscopes, PNAs, ONTs, and power supplies
- Understanding of networking fundamentals (PHY to Data Link layer)
Compensation & Benefits
- Competitive compensation package
- RSUs and sign-on bonus included
- Relocation support: Not available
