Job description

Sanmai is a Public Benefit Corporation advancing breakthrough neurotechnology through clinical expertise and AI-enabled precision medical devices. Our flagship technology uses focused ultrasound to open a new path in neurotherapeutics - helping people with mental health and neurological conditions find the relief they need. We're a mission-driven team that pairs scientific rigor with real human impact.

The Role

We're looking for a Software Engineer to help design, build, and evolve the software architecture behind our neurotechnology platform - from internal tooling to production-ready application and firmware code. You'll also own software verification and validation to ensure compliance with medical device standards, working cross-functionally with engineering, clinical, and regulatory teams across multiple locations. This is a rare chance to shape the software direction of a company working at the frontier of neuroscience, AI, and mental health.

What You'll Do

• Design and implement scalable applications, and write application and firmware code that meets performance, safety, and regulatory requirements
• Contribute to system architecture and lead software design reviews
• Build and maintain internal tools that streamline operations
• Own software V&V activities, including white-box testing, in compliance with ISO 13485
• Partner with quality and regulatory teams to support audits and filings
• Work in an agile process alongside cross-functional teams

What You Should Have

• Demonstrated leadership in software architecture and implementation
• Experience driving software V&V in compliance with ISO 13485
• Advanced proficiency in Python, C++, Qt 6 SDK, and PySide6, with solid object-oriented design
• Comfortable across Windows and Linux, with build and CI tooling (Make, CMake, Jenkins), Bash scripting, and Python unit testing (PyTest/unittest)
• Understanding of Secure Boot (Intel CPUs)
• Strong knowledge of database systems and software design patterns
• Proficiency with Jira, Confluence, Git, and XRay
• Bachelor's in Computer Engineering, Computer Science, or related field (Master's preferred)
• Nice to have: 5+ years developing for regulated medical devices, 5+ years with Rust, ML frameworks (PyTorch/TensorFlow), CUDA/OpenCL, Ubuntu customization, Libvirt or Xen, and Verilog
• Comfortable with high autonomy in a fast-moving startup and skilled at communicating complexity to technical and non-technical audiences

What You'll Achieve

You'll design and scale the software platform behind our flagship neurotherapeutic device, lead the V&V processes that support FDA submissions and international approvals, and help bridge neuroscience, software, and user experience into one coherent technical vision.

Full-time, based in Tucson, Arizona. Salary range: $140,000-$150,000/year.
