Embedded Software Engineer - Ethernet Retimers

• Debug & System Integration
• Work directly with the system validation team to debug firmware behavior across different Ethernet configurations, link states, and failure modes
• Investigate and fix firmware issues in embedded C, leveraging deep understanding of how Layer 1 PHY, SERDES, FEC/PCS, MAC, and retimer components interact
• Serve as the connective tissue between firmware and system validation teams, triaging issues and driving them to resolution without long handoff loops
• Customer Bring-Up & Field Support
• Support customer bring-up and integration activities, including triaging field issues and coordinating fixes with internal teams
• Partner with field applications engineers to diagnose and resolve deployment issues quickly
• Firmware Feature Development
• Contribute to firmware feature development for SERDES configuration, link training, equalization, and diagnostics
• Partner with SoC, field applications, and platform teams across the full product lifecycle
• Help bring new Taurus products from initial silicon bringup through customer deployment

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field
• 5+ years of experience in firmware development or embedded systems engineering
• Hands-on experience with Ethernet at the system or device level: Layer 1 PHY, SERDES, retimers, gearboxes, NICs, switches, or related devices
• Solid embedded C/C++ skills and comfort working in a firmware codebase on real hardware
• Ability to debug across the hardware/software boundary: register accesses, embedded SDKs, link state machines, PHY telemetry, debug print logs
• Familiarity with Linux development tools: gcc/clang, make, bash, gdb, git
• Strong communication skills and comfort working in a fast-moving environment where the problem in front of you may not have a clean solution

Preferred Qualifications

• Experience with switch or NIC management software, SAI, or OpenBMC
• Knowledge of PMA, FEC, or other PHY-layer subsystems beyond the SERDES
• Background with retimer or gearbox firmware or SDK/API development
• Python scripting for debug, test automation, or data analysis
• Experience with lab equipment: BERT, oscilloscopes, Viavi/Lecroy/Exfo/Keysight/Tektronix or similar
• Understanding of signal integrity: equalization, jitter, eye diagrams, link margin
• Prior experience mentoring engineers or leading debug efforts across teams

Salary range is $133,200 to $185,000 depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
