Location: Remote

Reports To: VP of Engineering, Software

I/ONX is leading the industry on cutting-edge AI technology, revolutionizing performance expectations, ease of use, and cost efficiency. With AI redefining the computing paradigm, solutions must evolve to unify innovations in software models, compilers, platforms, networking, and semiconductors. Our team developed the world’s first platform to enable CPUs, GPUs, ASICs, and FPGAs to work together for AI and High Performance Compute workloads. We value collaboration, curiosity, and a commitment to solving hard problems. We are growing our team and looking for contributors of all seniorities.

Role Overview:

As a Staff Software Engineer, you’ll be both a technical leader and a hands-on builder. You’ll shape the design and development of software systems that interface closely with advanced hardware, while also writing the code that brings those designs to life. You’ll collaborate with hardware architects, systems engineers, and product leaders to deliver software that is not only highly performant and reliable, but also scalable enough to power the next generation of AI and HPC workloads.

This role is for someone who thrives on building—driving architectural decisions, mentoring engineers, and rolling up their sleeves to create clean, production-ready systems that push the limits of performance.

What You’ll Do

  • Design, build, and ship system-level software, frameworks, and tools that unlock performance on advanced hardware.
  • Write Rust-based software that is performant, reliable, and safe, alongside code in C/C++ and Python where needed.
  • Collaborate with hardware teams to co-design solutions that maximize specialized compute architectures.
  • Architect and implement distributed systems, APIs, and libraries that scale across clusters and heterogeneous environments.
  • Dive deep into performance bottlenecks, debugging at the intersection of hardware and software.
  • Mentor engineers, guide design reviews, and help shape technical direction while staying close to the codebase.

Who You Are

  • Required Experience

  • 10+ years of software engineering experience, with a strong track record of shipping production systems.

  • Proficiency in Rust, with deep experience building performance-critical, concurrent, or systems-level applications.

  • Strong background in HPC, GPU/accelerator programming (CUDA, ROCm, OpenCL), or distributed systems.

  • Solid understanding of computer architecture, parallelism, and performance optimization.

  • Familiarity with AI/ML frameworks (e.g., PyTorch, TensorFlow, JAX) and their hardware interactions.

  • Proven track record of building APIs, SDKs, or developer tools used in production environments.

  • Experience mentoring engineers and leading architectural discussions.

  • Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or related field (PhD a plus).

  • Preferred

  • Experience with compilers, graph optimization, or runtime systems for ML/HPC.

  • Background with containerization (Docker, Kubernetes) in HPC/AI settings.

  • Contributions to Rust open-source projects, particularly in the HPC/AI ecosystem.

  • Knowledge of networking, storage, or I/O optimization in high-throughput environments.

What we offer

We believe great work starts with a great foundation of support. Here’s how we invest in you:

  • 100% company-paid health insurance for employees and qualified dependents, because your family’s health matters to us too
  • Flexible Time Off (FTO) to rest, recharge, and take the time you need — no accruals, just trust
  • Company-paid life insurance to provide peace of mind
  • Company contribution to your Flexible Spending Account (FSA) to help with healthcare and dependent care costs
  • Optional add-ons like extra life insurance and critical illness protection if you want additional coverage
  • Paid holidays off so you can truly unplug
  • Work From Anywhere — flexibility to do your best work from wherever life takes you
  • A supportive culture that values balance, wellbeing, and being human
