Hardware Engineer (San Francisco)

Hardware Engineer

Must be eligible to obtain a U.S. security clearance

We're seeking a Hardware Engineer to lead the mechanical and thermal design of rugged, high-performance defense platforms. You'll work on structural simulation, thermal management, and rapid prototyping, taking systems from concept to field validation. This is a highly hands-on role involving testing, iteration, and collaboration with cross-functional teams.

Job Description

Thermal & Structural Engineering

• Design and validate active and passive thermal management systems for high-power laser components
• Conduct FEA for stress, vibration, modal analysis, and thermal performance using tools like ANSYS or SolidWorks Simulation
• Optimize designs for durability, weight, and thermal reliability under dynamic load conditions

Mechanical Design & Prototyping

• Create 3D CAD models for structural and thermal hardware using SolidWorks, Creo, or equivalent
• Rapidly build and iterate mechanical prototypes using CNC, additive manufacturing, or other methods
• Plan and conduct environmental tests: vibration, shock, and field robustness trials

Material Selection & DFM

• Select and qualify metals, polymers, and composites based on thermal, mechanical, and EMI requirements
• Run DFM reviews to optimize geometry, tolerances, and manufacturability
• Collaborate with suppliers and manufacturers to transition prototypes to production

Manufacturing & Documentation

• Generate GD&T drawings, BOMs, and assembly instructions
• Ensure compliance with MIL-STD and ITAR standards throughout hardware lifecycle
• Support final assembly, system integration, and field testing

Cross-Functional Integration

• Partner with optics, firmware, electronics, and control systems teams to integrate your designs into full systems
• Provide hands-on support during product builds and test cycles

Qualifications

• Minimum 2-8 years in mechanical or hardware engineering (defense, aerospace, robotics, or similar)
• Proficient in CAD tools (SolidWorks, Creo, etc.)
• Strong in FEA tools for thermal and structural analysis (ANSYS, SolidWorks Simulation)
• Experience with CFD, heat transfer simulation, and vibration/shock testing
• Hands-on with prototyping and fixture development
• Familiarity with material properties, design tolerances, and manufacturing methods
• BS or MS in Mechanical Engineering, Aerospace Engineering, or related field
• Passionate about building, breaking, and improving physical systems
• Strong problem-solving skills, fast execution, and excellent communication in cross-functional environments
• Experience with vacuum or environmental chamber testing
• Familiarity with optical alignment or laser safety standards
• Background in EMI / EMC shielding and design
• Experience with ITAR compliance or active security clearance
