About the role

You will work closely with hardware architects, compiler engineers, and runtime engineers to shape how numerical algorithms are expressed, executed, and optimized on the SPU.

Prototype and implement core numerical linear algebra kernels and libraries for the SPU.
Collaborate with hardware architects, compiler engineers, and runtime teams to evaluate algorithm-architecture tradeoffs and ensure numerical primitives map cleanly to the SPU programming model.
Vorticity is building the world's first Scientific Processing Unit (SPU https://pyrite9.com), a new class of silicon purpose-built to accelerate scientific computing beyond the limits of GPUs.
From day one, you will help build the numerical software foundation of the SPU.

Familiarity with numerical computing libraries such as BLAS, LAPACK, FFTW, Eigen, SuiteSparse, PETSc, cuBLAS, cuSOLVER, cuSPARSE, cuFFT, or similar.
Familiarity with performance analysis tools or modeling techniques, including profilers, roofline models, hardware counters, or analytical performance models.

Strong proficiency in C, C++, and Python.
Comfort working close to hardware and writing performance-critical, low-level code.
Experience with parallel or accelerator programming models such as CUDA, OpenMP, MPI, SYCL, HIP, or similar.
Ability to reason about memory layouts, cache behavior, bandwidth, arithmetic intensity, and parallel execution.
Solid understanding of concurrency fundamentals, including race conditions, atomics, synchronization, and thread/process behavior.
Exposure to compilers, runtimes, code generation frameworks, or domain-specific languages for numerical computing.
Experience applying numerical methods in scientific domains such as physics, geophysics, CFD, climate, materials, fusion, or finance.
Excellent written and verbal communication skills
Comfort operating in an early-stage environment where the hardware, compiler, and software stack are evolving together.
Willingness to put in the hard work needed to bring the SPU to life.
Above all: low ego.
Vorticity's mission is to expand human ingenuity.

As passionate scientists and engineers, we are well aware of the plethora of critical problems in the world that cannot be solved because humanity simply does not have enough computing power.
To address this, Vorticity is developing a radically new silicon chip architecture and system to dramatically accelerate scientific computing problems.
To do that we are building a team of exceptional people to work together on big problems.
We are designing tightly coupled software-hardware systems around applied mathematics workloads to deliver order-of-magnitude performance gains.
This position is ideal for someone who enjoys moving fluidly between applied math, numerical algorithms, and parallel programming, and who wants to help build a new scientific computing platform from the ground up.
