Staff Engineer, Digital ASIC Design (CONTRACT)
About the role
The role of the Staff Digital ASIC Designer offers the opportunity to work within the heart of the product development team and founders and to own the core of what will set Butterfly Network apart. This individual will design, implement, and verify digital signal processing, high speed interface, and system-on-a-chip logic for a suite of next-generation products.
Responsibilities
- Develop low-power RTL for large SoCs in an advanced node.
- Implement and optimize signal processing algorithms in RTL.
- Integrate multiple embedded processor cores into a large design.
- Develop efficient high bandwidth on chip data paths.
- Other Technology, Architecture, & Productivity duties as assigned.
Qualifications
- Bachelor's, Master's, or PhD in Electrical Engineering or Computer Engineering (or equivalent practical silicon design experience).
- 8+ years (typical Staff level) in digital IC / ASIC / SoC design with substantial hands-on RTL ownership and at least one major-IP or full-chip tapeout cycle.
- Proven ownership of a defined digital IP/subsystem from micro-architecture and RTL implementation through verification closure and tapeout support.
- Strong RTL skills in SystemVerilog/Verilog, including pipelined datapaths, control logic/state machines, and high-throughput streaming interfaces.
- Experience designing sustained high-throughput datapaths, including buffering/FIFOs, arbitration/backpressure, bandwidth budgeting, and SRAM/memory interface considerations.
- Strong understanding of silicon-level design constraints, including clock/reset architecture, CDC/RDC risk mitigation, power-aware design, and PPA tradeoffs.
- Effective collaboration with verification to drive functional closure through signoff (SV/UVM and/or Python-based frameworks such as cocotb).
- Experience building and using bit-accurate reference models (e.g., Python) to validate fixed-point behavior and enable end-to-end checking.
- Experience supporting post-silicon bring-up/debug and silicon correlation, partnering with firmware/validation to root-cause issues and deliver fixes.
- Strong cross-functional communication to close hardware–firmware interfaces (register maps, control/status paths, data-plane contracts) with systems/firmware stakeholders.
