Senior Device Engineer - Mechanical

About the role

Alarm.com (ADC) is a rapidly expanding technology company developing innovative cloud and device solutions for connected-home devices, including video doorbells, cameras, sensors, and control modules. We are seeking a hands-on Senior Device Engineer - Mechanical to join our hardware team in San Diego.

Responsibilities

• Own product development end-to-end: Independently drive mechanical design of consumer electronics products from concept and industrial-design intent through detailed design, prototyping, and mass production.
• Lead large-assembly design: Architect and manage complex, multi-part 3D CAD assemblies, maintaining design intent, robust part relationships, and revision discipline across the full product.
• Create mockups and functional prototypes to evaluate concepts, validate fit and function, and accelerate design iteration.
• Manage simulation and analysis: Plan and manage simulations and engineering analysis, assess risks and design options, and justify decisions against product and cross-functional requirements.
• Drive industrial-design integration: Manage ID discussions to balance and accommodate optical, acoustic, RF, usability, reliability, and operational-efficiency requirements across the full range of intended environmental conditions.
• Design for manufacturing across processes: Design and optimize parts for injection molding, die-cast metal, over-molding, silicone (LSR) injection molding, compression molding, double-shot/two-shot molding, CNC machining, sheet metal, die-cut, and stamped processes.
• Drive tolerance and DFX resolution: Perform tolerance stack-up analysis and lead resolution of DFM/DFA/DFX feedback to ensure manufacturable, reliable, cost-effective designs.
• Prepare manufacturing drawings: Produce detailed 2D drawings for manufacturing that capture critical dimensions, tolerances (GD&T), manufacturing methods, materials, finishes, colors, and all requirements necessary to produce quality products.
• Prepare BOMs, RFQs, and documentation: Prepare preliminary and detailed BOMs and RFQ packages, and document decisions, meeting minutes, research conducted, analyses and simulations performed, engineering assumptions and calculations, and risks with mitigation options.
• Engage vendors and partners: Work directly with tooling vendors and ODM/manufacturing partners across Asia to drive part quality, tool builds, and issue resolution through EVT, DVT, and PVT.
• Serve as the cross-site and cross-functional liaison: Act as the on-site mechanical point of contact for San Diego-based TPMs, EEs, FW, and Acoustics, and coordinate mechanical execution with the distributed ME team in Taiwan, DC, and Florida — ensuring the complete system meets product requirements and is validated and verified according to established engineering standards and methods.

Qualifications

• Bachelor's degree or above in Mechanical Engineering or a related field.
• 5+ years of mechanical design experience, with significant experience in consumer electronics, and a demonstrated ability to take products from concept to manufacturing independently.
• Proficient 3D CAD skills with strong large-assembly management experience (Creo strongly preferred).
• Thorough working knowledge of designing parts for injection molding, die-cast metal, over-molding, silicone injection molding, compression molding, double-shot molding, CNC, sheet metal, die-cut, and stamped processes.
• Proven experience with tolerance stack-up analysis, GD&T, and resolving DFM/DFA/DFX feedback.
• Experience producing manufacturing-ready 2D drawings, BOMs, and RFQ packages, and maintaining clear engineering documentation.
• Demonstrated experience working with vendors and manufacturers in Asia and collaborating with cross-functional, globally distributed teams (ID, Optics, Acoustics, EE, RF, FW, QE).
• Self-motivated with the ability to own product development autonomously and coordinate effectively across remote sites and time zones.
• Strong written and verbal communication skills in English.

Preferred Qualifications

• Direct experience developing cameras and/or video doorbells or similar connected-home consumer devices.
• Experience working in fast-paced consumer electronics development cycles.
• Experience coordinating mechanical work across multiple global sites and external manufacturing partners.
