About Positron Positron AI develops custom hardware systems that accelerate AI inference, delivering step-function gains in performance per dollar and performance per watt over GPU-centric approaches. Backed by NEA.
About the role
As a Senior Mechanical Engineer at Positron AI, you will own the mechanical, thermal-mechanical, and enclosure design of our AI inference platforms—from carrier-board mechanical integration and chassis design through rack-level packaging of our Asimov-based systems. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Experience: BS/MS in Mechanical Engineering and 7+ years designing electromechanical and enclosure hardware for high-performance electronic systems, spanning the full NPI lifecycle from concept through volume production
- Mechanical Design & Analysis: Proven expertise in 3D CAD (SolidWorks and/or Creo), detailed drawings and GD&T, tolerance stack-up analysis, and structural/thermal simulation (e.g., SolidWorks Simulation/Flow, Ansys)
- DFx Discipline: Demonstrated track record applying DFM/DFA and FMEA to drive cost, quality, and manufacturability in high-volume or high-complexity production environments
- Collaboration: Strong ability to write clear mechanical specifications and communicate trade-offs across electrical, thermal, ASIC, firmware, and operations teams
More about this role
As a Senior Mechanical Engineer at Positron AI, you will own the mechanical, thermal-mechanical, and enclosure design of our AI inference platforms—from carrier-board mechanical integration and chassis design through rack-level packaging of our Asimov-based systems. You will ensure that the structural, thermal, and manufacturability characteristics of our high-power hardware meet the demands of high-density HPC and data center environments, and you will serve as the primary mechanical interface to our contract manufacturers and custom-part fabricators. This is a high-impact role requiring deep expertise in electromechanical design for high-performance electronic systems and the ability to drive designs from concept through volume production with external partners.
This role is based in-office at our Spokane Valley, WA location. Candidates must be able to work on-site as required.
- Mechanical Design Ownership: Own the mechanical design of enclosures, chassis, and carrier-board mechanical integration for rack-mount (1U/2U) inference systems—including spatial studies, conceptual and detailed design, solid models, drawings, BOMs, and tolerance stack-up analysis.
