Open positions
Senior BackEnd (Physical design) Engineer
Leads full RTL-to-GDSII backend flow for semiconductor design, focusing on timing closure, low-power optimization, and physical implementation (floorplanning, CTS, IR-drop) while collaborating with design teams and external vendors.
VLSI Design Engineer
VLSI Design Engineer responsible for designing cutting-edge communication systems from scratch, including micro-architecture definition, RTL coding in Verilog/SystemVerilog, synthesis, timing analysis, and PPA optimization, collaborating closely with verification, DFT, and physical design teams.
System Integration Engineer
Hands-on system integration engineer at Retym (Ramat Gan, fully on-site) who brings up and validates PCBs, EVBs, and optical modules with customer platforms — debugging silicon-to-system issues, analyzing BER/signal integrity in the lab, and building Python/MATLAB test automation. Requires a B.Sc. in EE and 6+ years of hardware/system validation experience.
Optical DSP Chief Architect
Leads DSP system architecture for high-speed optical transceivers (800G/1.6T+), optimizing algorithms like equalization and clock/data recovery while collaborating with hardware/photonics teams to design next-gen optical chips.
