Principal Engineer role focusing on embedded firmware and software development for advanced connectivity products in AI infrastructure.
Обязанности
- Join Astera Labs’ Signal Connectivity Engineering team as a Principal Engineer shaping the firmware and software that makes advanced connectivity products adaptive, reliable, and production-ready . You will own embedded software across analog connectivity and Ethernet retimer platforms, from low-level hardware abstraction and calibration through link management, diagnostics, validation, and customer deployment.
- This is a high-impact role at the intersection of embedded systems, mixed-signal hardware, and Ethernet physical-layer behavior. You will work across architecture, lab debug, automation, and customer integration while partnering with silicon, analog, systems, validation, and applications teams. Your work will help deliver purpose-built connectivity for rack-scale AI infrastructure as Astera Labs continues to scale.
Требования
- Bachelor’s degree in Computer Science , Electrical Engineering, Computer Engineering, or a related field.
- 8–12 years of experience developing embedded firmware or software for resource-constrained systems, with ownership from architecture through production.
- Strong embedded C/C++ skills and deep knowledge of microcontroller architecture, memory-mapped peripherals, interrupt handling, and bare-metal firmware.
- Hands-on experience with Ethernet or high-speed connectivity devices, including Layer 1 PHYs, SERDES, retimers , gearboxes, NICs, switches, or related systems.
- Solid understanding of physical-layer behavior, link state machines, register-level debug, and hardware/software integration.
- Experience with feedback systems, adaptive algorithms, calibration, or tuning of analog or mixed-signal subsystems.
- Proficiency with Microsoft-based development environments and Linux command-line tools, including GCC or Clang, Make, Bash, GDB, and Git.
- Clear written and verbal communication, systematic debugging skills, and the ability to operate effectively in a fast-moving environment with ambiguity.
Будет плюсом
- Master’s degree in Computer Science , Electrical Engineering, Computer Engineering, or a related field .
- Python experience for test automation, debug tooling, data analysis, or lab workflows; hands-on experience with Jenkins and CI/CD infrastructure.
- Familiarity with mixed-signal systems and analog signal paths, including ADC/DAC interfaces, sensor readout, transimpedance amplifiers, transmit drivers, CTLE/DFE equalization, CDR/PLL circuits, or thermal control.
- Experience with retimer or gearbox firmware, SDK/API development, optical modules or pluggable optics, high-speed copper connectivity, Ethernet PHY subsystems, FEC, PMA, or signal-integrity analysis.
- Experience using oscilloscopes, BERTs, logic analyzers, and other lab equipment; familiarity with FPGA emulation, pre-silicon validation, RTOS, device drivers, coroutines, mentoring, or recruiting.
- We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.
