Software Product Manager

What MatX Is Building MatX is on a mission to make the world's best AI models run as efficiently as possible, accelerating global progress in AI quality and accessibility. We are building cutting-edge AI infrastructure at the intersection of hardware and software, and our team is growing quickly.  This is MatX's first software-focused Software Product Manager. You'll start by doing mostly internal work that sits at the boundary of product management and technical program management: mapping interfaces between sub-teams, driving API boundary decisions, and making sure the compiler, simulator, kernels, and runtime teams are building toward a coherent whole. You will be managing risks and mitigations applying structural problem solving methodology as needed. You'll also be shaping the software side of our product definition — what goes into the SDK, what tools and documentation we ship, and what kernels and systems software we build or expose to partners.  What You'll Do Here Partner Management: Own the SDK partner relationship model — which partners get early access, what commitments we make, and how we collect and triage feedback API & Systems Definition: Define the shape of the MatX SDK and the systems software surface area we ship to customers: runtime APIs, profiling tools, compiler interfaces, and simulator integrations Own and document API boundaries between the compiler, simulator, kernels, and runtime sub-teams, and across hardware, architecture, and systems software — driving alignment on interface contracts, timelines, and dependencies Kernel Strategy: Determine what kernels MatX should author versus expose for customers to write themselves, and define the tools and documentation that make customer kernel authorship tractable Technical Translation: Translate between customer needs and engineering constraints, and contribute to roadmap prioritization across the software stack with a clear view of customer impact and strategic fit Who You Are Experience in product management or technical program management, working directly on systems software, compilers, ML frameworks, or developer-facing SDKs Strong enough technical depth to read a Rust API, understand what a compiler IR is, and have a meaningful conversation with an engineer about simulator fidelity tradeoffs — you don't need to write production code, but you need to earn trust with people who do  Experience defining and documenting API contracts or SDK specifications in a technical organization  Comfort operating in ambiguity and doing the unglamorous internal coordination work before the external product work becomes available  Strong written communication — you'll write a lot of internal specs, interface docs, and partner-facing materials  Bonus Points If You Have Background in ML accelerator software (inference runtimes, kernel libraries, compiler backends, or ML frameworks such as PyTorch, JAX, or TensorFlow at the systems level) Experience working with early SDK partners or developer ecosystem programs at a hardware or developer-tools company  Familiarity with CUDA/HIP, MLIR, LLVM, or similar low-level toolchains — not necessarily as an author, but as someone who has shipped documentation or tooling around them Previous experience at a company that shipped novel hardware with a co-designed software stack (GPU vendors, custom accelerator startups, or similar)  Previously a software engineer Compensation The US base salary for this full-time position is determined based on a variety of factors including role, experience, location, job related skills, and relevant education and training.
