Principal Engineer, Hardware Design (AI2518)

Description
Job Title: Principal Engineer, Hardware Design
Job Location: San Jose, CA (This position requires a full-time, on-site presence in our San Jose, CA office)
Job ID: AI2518
Job Description
We are seeking a Principal ASIC Design Engineer with deep expertise in RTL design and ground-up block-level silicon development. The ideal candidate will own complex design blocks from microarchitecture and RTL implementation through verification support and silicon bring-up. This position offers the opportunity to shape and influence the design architecture and methodology of SiMa's silicon in a fast-paced startup environment.

Areas Of Focus

• Own microarchitecture definition and RTL implementation of complex blocks from concept through silicon.
• Drive ground-up block design, owning each block from specification and microarchitecture to RTL, integration, and bring-up.
• Develop high-quality, synthesizable RTL (Verilog/SystemVerilog), including custom logic, protocol adaptation, and data-path optimizations.
• Define block-level interfaces, microarchitectural trade-offs, and design specifications.
• Collaborate with verification, physical design, architecture, and firmware teams to ensure each block meets functional, timing, power, and area targets.
• Drive block-level synthesis, timing closure, and DFT readiness.

Key Requirements

• Master's degree in Electrical Engineering, Computer Engineering, or related field.
• 10+ years of experience in ASIC design, with a strong focus on block-level RTL design and silicon development.
• Proven track record of ground-up block design, taking blocks from microarchitecture and RTL through to working silicon.
• Expert-level RTL design skills (Verilog/SystemVerilog), with hands-on experience in synthesis, timing closure, and DFT concepts.
• Strong understanding of microarchitecture trade-offs, data-path and control logic design, and block-level optimization for power, performance, and area.
• Experience with post-silicon validation and debug, using lab equipment such as oscilloscopes, logic analyzers, and protocol analyzers.

Nice To Have

• Experience designing hardware for machine learning / AI accelerators.
• Experience integrating blocks into larger SoCs.
• Experience implementing or integrating high-speed interfaces such as PCIe and UCIe.
• Exposure to firmware or driver development for high-speed interfaces.

Personal Attributes
Can-do attitude. Strong team player. Curious, creative and good at solving problems. Execution and results-oriented. Self-driven, Thinks Big and is highly accountable. Good communication skills.
