Mechanical Engineer

Applicants must be located in the Petaluma area and able to commute to the office Monday through Friday

Digilock is a leading provider of security solutions, designing and manufacturing locking systems used in workplaces, gyms, healthcare facilities, and beyond. We combine precision mechanical engineering with smart technology to build locks people trust every day.

Digilock is seeking a Mechanical Engineer to design, develop, and improve mechanical lock components and systems from concept through production. This role involves hands‑on prototyping, design for manufacturability, and cross‑functional collaboration with electrical, firmware, and manufacturing teams. Experience with electromechanical systems is a plus, as many of our products integrate mechanical locking mechanisms with electronic components (motors, solenoids, sensors, PCBs).

Key Responsibilities

• Design, model, and prototype mechanical lock components and assemblies using Solid Works
• Conduct tolerance analysis, tooling design review, and DFM/DFA evaluations to optimize designs for injection molding, die casting, and machined parts
• Develop and execute test plans (durability, cycle testing, environmental, and failure analysis) to validate product performance and reliability
• Collaborate with electrical engineers and firmware developers on electromechanical integration (motors, solenoids, actuators, sensors) for smart lock products
• Partner with manufacturing and quality teams, including Digilock’s overseas manufacturing locations, to troubleshoot production issues and support NPI
• Create and maintain detailed engineering documentation: drawings, BOMs, specifications, and change orders
• Support cost reduction, value engineering, and continuous improvement initiatives on existing product lines
• Ensure designs comply with relevant industry standards and certifications (UL, ANSI/BHMA, etc.)

Required Qualifications

• Bachelor's degree in Mechanical Engineering or related field
• 5+ years of experience in mechanical product design, ideally with consumer hardware, locks, hardware/fixtures, or similar precision mechanical products
• Proficiency in Solid Works
• Strong understanding of manufacturing processes: injection molding, stamping, die casting, CNC machining
• Experience with GD&T, tolerance stack‑up analysis, and DFM principles
• Solid problem‑solving skills and ability to manage multiple projects simultaneously

Preferred Qualifications

• Experience with electromechanical systems — integrating motors, solenoids, sensors, or actuators with mechanical assemblies (strong plus)
• Familiarity with lock/security hardware, access control systems, or similar regulated mechanical products
• Experience with UL or ANSI/BHMA certification processes
