You will translate micro-architecture into clean, high-quality RTL and drive it through synthesis and timing closure. Just as important, the ideal candidate leverages strong firmware coding experience to drive pre-silicon simulation, develop bare-metal diagnostics, and ensure seamless hardware-software integration-for example, writing firmware on an embedded RISC CPU IP to control on-chip analog hardware blocks and low-speed control/calibration loops for optical components. Strong digital ASIC fundamentals, paired with the ability to debug complex designs in emulation and on silicon, round out the profile., * B.S. or M.S. in Electrical/Electronics or Computer Engineering (or related), with relevant digital ASIC design experience. * Demonstrated experience taking digital designs from RTL through synthesis, timing closure, and silicon bring-up. Core Technical Skills * Strong fundamentals in digital ASIC design, micro-architecture, and best RTL coding methods. * Firmware / embedded C development, including bare-metal programming on an on-chip RISC CPU IP (e.g., RISC-V or Arm) to drive analog blocks and low-speed loops. * Knowledge of AMBA and serial protocols, processors, and silicon bring-up sequences. * Strong design, emulation, and silicon debug skills, with proven hardware-software integration experience. * Expertise in synthesis, constraints, timing closure, and equivalence checks (Formality / Conformal). * Experience with Lint / CDC / RDC tools. Professional Skills * Customer-support orientation and excellent communication and oratory skills. Preferred Qualifications * Familiarity with interconnect protocols such as PCIe (Gen5/6/7) and UCIe. * Experience integrating vendor CPU IP and developing the associated firmware, drivers, and diagnostics. * High-speed wireline / SerDes-based SoC experience; UPF low-power design, DFT, and scan/ATPG flows. * Scripting proficiency (Python, Tcl) ## Description * Develop micro-architecture and author high-quality, synthesizable RTL following best-in-class coding methods and design-for-verification / design-for-test practices. * Write firmware and bare-metal diagnostics on embedded RISC CPU IP to configure and control on-chip analog blocks and low-speed control/calibration loops for optical components. * Drive pre-silicon simulation and hardware-software co-verification, validating firmware against RTL well ahead of tape-out. * Integrate processor subsystems-including licensed CPU IP-AMBA fabrics, and serial/interconnect interfaces (e.g., PCIe, UCIe) into the SoC/ASIC. * Drive the full implementation flow: synthesis, timing constraints (SDC), timing closure, and equivalence checking (Formality / Conformal), with clean Lint / CDC / RDC signoff. * Build and run emulation environments; lead silicon bring-up sequences and post-silicon debug, root-causing and resolving issues on hardware. * Provide responsive support-triaging design problems and delivering timely solutions-and collaborate with analog/mixed-signal, DSP, verification, and physical-design teams. ## Related Videos - [The Billion Dollar Machine: First Time Right.](https://www.wearedevelopers.com/videos/393-the-billion-dollar-machine-first-time-right) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [JavaScript?
