Company

hirify.global is an artificial intelligence company developing multimodal, proactive intelligence and next-generation hardware that connects people with intelligent systems.

What you will do

• Lead structural, thermal, and dynamic FEA across hardware enclosures, assemblies, flex systems, and interconnects from concept through design validation.
• Develop simulation models for drop, vibration, fatigue, thermal cycling, and mechanical load conditions.
• Translate simulation findings into design recommendations covering geometry, materials, wall thickness, weight, stiffness, thermal performance, and manufacturability.
• Own tolerance stack-up analysis and dimensional management for critical assemblies.
• Correlate simulation results with physical test data and refine models using feedback from reliability and quality teams.
• Support design of experiments and design verification planning by defining simulation-based pass/fail criteria.

Requirements

• 8+ years of FEA and structural simulation experience in consumer hardware, aerospace, medical devices, or precision manufacturing.
• Expert proficiency in ANSYS, Abaqus, Nastran, or an equivalent FEA platform, including meshing, boundary conditions, nonlinear materials, and contact modeling.
• Strong fundamentals in solid mechanics, materials science, heat transfer, and dynamics.
• Experience with drop, vibration, fatigue, and thermal analysis for physical products.
• Proficiency in SolidWorks, NX, Creo, or equivalent 3D CAD tools, including preparing geometry for simulation.
• Track record of correlating simulation predictions with physical test results and iteratively improving models.

Nice to have

• Coupled thermal-structural or fluid-structure interaction simulation for compact consumer electronics.
• Experience with flexible PCB or overmold assembly mechanics.
• Acoustic or vibration analysis for wearable or handheld devices.
• Topology optimization, generative design, injection molding, die casting, or precision CNC machining experience.

Culture & Benefits

• Hands-on collaboration with product design engineering, industrial design, mechanical engineering, reliability, and quality teams.
• Simulation directly informs hardware design from early development through production release.
• Full-time employment with a stated US base salary range of $120,000–$300,000 annually.
• Total compensation may include additional components and benefits depending on the role.
