RTL Engineer Datapath

Anthriq is a signal processing infrastructure company. We build the full acquisition and compute stack for human-aware technology — from custom analog front-end IP that captures biosignals at the source, to signal-first compute systems built for time-critical workloads.

Anthriq Silicon is our ground-up effort to build a new compute category. Read More About Anthriq Silicon Program here: anthriq.com/silicon

About the Role
We are building a compute-heavy 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
