RTL Engineer — Datapath

About The Company

Anthriq builds foundational infrastructure for human-aware technology. Our Human Body API captures, decodes, and translates biosignals, brain, muscle, and physiological data into real-time, programmable applications. With a modular, end-to-end platform, we enable teams to move from signal capture to deployment without reinventing the stack, powering a future where technology responds to human intent, not interfaces.

About The Role

We are building a high-performance signal processing ASIC — a multi-core vector processor with a custom ISA. You will implement the execution units, register files, and data forwarding network that form the computational core of the processor.

Responsibilities

• Implement all execution units across the custom ISA (integer, floating-point, fixed-point,
  
  

complex arithmetic)

• Build multi-port register files (flip-flop-based, conflict-free, multi-read multi-write)
• Implement the bypass/forwarding network for hazard-free data delivery
• Integrate IEEE 754-compliant floating-point datapaths (half, single, double precision)
• Implement saturating arithmetic, configurable rounding modes, and extended-precision
  
  

accumulators

• Optimize critical arithmetic paths (carry-save adders, Wallace trees, Booth-encoded
  
  

multipliers)

• Work with the verification team to achieve per-opcode coverage across all supported data
  
  

types.

Requirements

• 5+ years RTL design in SystemVerilog
• Strong arithmetic unit design (multipliers, dividers, adders — not just instantiating IP)
• IEEE 754 floating-point implementation experience
• Fixed-point arithmetic, saturation modes, rounding modes
• Understanding of pipelining and multi-cycle datapath design
• Comfortable working from a detailed architecture spec
  
  

Nice to Have

• DSP datapath experience (MAC units, butterfly structures, CORDIC)
• Vector/SIMD lane design
• Experience with extended-precision or redundant arithmetic
• SoftFloat or similar reference model experience for FP verification
