Senior Device Engineer - Mechanical

Alarm.com (ADC) is a rapidly expanding technology company developing innovative cloud and device solutions that deliver a unified, connected service to millions of residential and commercial properties in the US and abroad. We are seeking a hands‑on Senior Device Engineer – Mechanical to join our hardware team in San Diego and help define the future of connected‑home devices, including video doorbells, cameras, sensors, and control modules.

As the Senior Device Engineer – Mechanical in our San Diego office, you will independently own the mechanical design of new products from concept through manufacturing. You will serve as the on‑site mechanical point of contact for our local Technical Program Managers, Electrical Engineers, Firmware Engineers, and Acoustics Engineer, while coordinating closely with our mechanical engineering team across Taiwan, Washington DC, and Florida and our manufacturing partners in Asia. This role operates in the fast‑paced, high‑cadence development environment that defines consumer electronics.

Key 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.
• Build mockups and prototypes: 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.

Required 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.

Please note that sponsorship of new applicants for employment authorization, or any other immigration‑related support, is not available for this position at this time.
