What you will do

• Design, implement, and maintain real-time embedded firmware in C for high-performance connectivity
• Develop low-level drivers, initialization flows, interrupt handling, and control logic for complex hardware blocks
• Bring up and debug firmware in pre-silicon environments and on silicon
• Work with architecture, design, and verification teams to define HW/FW interfaces
• Triage and resolve firmware issues reported by validation, product applications, and customers
• Take part in design reviews and code reviews
• Develop and extend the company SDK, including APIs, device management, firmware update, telemetry, and diagnostics capabilities
• Support customer requests and engagements

Required qualifications

• BSc/MSc in Computer Science, Electrical Engineering, Computer Engineering, or a related field
• 10+ years of hands-on experience as a firmware engineer
• Proven experience in embedded and real-time firmware development
• Strong programming skills in C on resource-constrained, bare-metal, or RTOS-based systems
• Solid understanding of processor architecture, memory-mapped registers, interrupts, and HW/SW interaction
• Strong debugging skills on real hardware using JTAG debuggers, logs, and register-level analysis
• Broad system-level understanding of how silicon, firmware, SDK, host software, and platform interact
• A team player with excellent communication skills
• Comfort with ambiguity and ownership in a fast-moving, high-growth company

Nice to have

• Experience with pre-silicon emulation platforms such as Cadence Palladium or Synopsys ZeBu
• Knowledge of PCIe (link training, enumeration, configuration space, error handling)
• Experience developing SDKs, host-side libraries, or APIs (C/C++ or Python) that interface with embedded firmware
• Experience working directly with customers or supporting customer integration and field issues
• Experience with silicon bring-up of new SoCs
• Python scripting for test automation, debug, or data analysis
