Mechanical Engineer

About Ironsite

The Role

What You'll Do

• Design Ruggedized Wearables: Lead mechanical design for body-worn and head-mounted camera systems that survive drops, dust, water, extreme temperatures, and 8+ hour daily use on active construction sites
• DFM & Manufacturing: Own design for manufacturing, work with suppliers and contract manufacturers to transition designs from prototype to high-volume production while optimizing for cost and reliability
• Enclosure & Mounting Systems: Design lightweight, ergonomic enclosures and mounting hardware (hard hat clips, vest mounts, chest harnesses) that workers will enjoy wearing all day
• Testing & Validation: Develop and execute reliability test plans including drop testing, vibration testing, environmental testing (IP rating, temperature cycling), and field durability validation with real users
• Cross-Functional Collaboration: Work closely with electrical engineers, firmware engineers, industrial designers, and field ops to integrate cameras, batteries, sensors, and connectivity into cohesive wearable systems

Job Requirements

• Bachelors degree (B.S.) in Mechanical Engineering or related field
• 3+ years of experience in mechanical design for consumer electronics, wearables, or ruggedized hardware
• Strong CAD skills (SolidWorks, Fusion 360, or similar) with portfolio demonstrating end-to-end development from concept to contract manufacturing
• Proven experience with DFM principles, injection molding, CNC machining, and assembly processes
• Hands-on prototyping experience—comfortable building and testing physical prototypes quickly
• Experience with environmental testing standards (IP ratings, drop test standards, MIL-STD or similar)

Preferred Qualifications

• Experience designing wearable devices, body-worn cameras, or head-mounted systems
• Background in ruggedized or industrial hardware (construction, military, oil & gas, public safety)
• Knowledge of battery integration, thermal management, and sealing/gasketing for waterproof enclosures
• Experience working with overseas contract manufacturers (Asia)
• Familiarity with FEA/CFD simulation tools for structural or thermal analysis
• Understanding of ergonomics and human factors for extended-wear devices

Location & Compensation

• San Francisco Bay Area (on-site)
• Hyper competitive salary and equity package
• Full benefits including health, dental, vision, and 401k +6% match
