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 Mechanical Engineer to join our hardware team in Taiwan and drive the mechanical design of connected-home devices, including video doorbells, cameras, sensors, and control modules.

This is an execution-focused senior engineering role. You will personally own the mechanical design of your products from concept through mass production — modeling, prototyping, analyzing, and validating — while working shoulder-to-shoulder with our industrial design, electrical, optical, acoustic, RF, and quality teams, and directly with our manufacturing partners across Asia in the fast-paced development cadence that defines consumer electronics.

Key Responsibilities

Own your product's mechanical design end-to-end: Independently execute detailed mechanical design of consumer electronics products from concept and industrial-design intent through prototyping, validation, and mass production.

Design in CAD daily: Create and manage detailed part and multi-part assembly models, maintaining design intent, robust part relationships, and revision discipline (Creo strongly preferred).

Build mockups and prototypes: Create mockups and functional prototypes to evaluate concepts, validate fit and function, and accelerate design iteration.

Solve build problems with rigor: Plan and execute DOEs and engineering analysis to resolve issues found at EVT/DVT/PVT — sealing and air-tightness, gasket compression, thermal, structural, and cosmetic — and carry solutions into production.

Integrate dense subsystems: Package Wi-Fi/BT antennas, camera optics, IR and light guides, speakers/microphones, and thermal solutions into compact, sealed, weatherproof enclosures that meet product requirements across the full range of environmental conditions.

Design for manufacturing: Design parts for injection molding, over-molding, silicone (LSR), double-shot molding, die-cast metal, CNC, sheet metal, die-cut, and stamped processes; perform tolerance stack-up analysis and drive DFM/DFA/DFX resolution with vendors.

Prepare manufacturing documentation: Produce 2D manufacturing drawings with critical dimensions, tolerances (GD&T), materials, finishes, and colors; prepare BOMs and RFQ packages; document decisions, analyses, assumptions, and risks per team standards.

Support builds at the factory: Work directly with tooling vendors and ODM partners through tool bring-up, first articles, and EVT/DVT/PVT builds, including on-site support at manufacturing sites in Asia.

Collaborate cross-functionally: Partner closely with Industrial Design, Optics, Acoustics, EE, RF, and QE, and with supplier-quality teams on component and finish issues, to deliver a fully validated product.

Required Qualifications

Bachelor's degree or above in Mechanical Engineering or a related field.

5+ years of hands-on mechanical design experience in consumer electronics, with demonstrated personal ownership of products from concept to mass production.

Proficient daily 3D CAD skills with solid assembly-management practice (Creo strongly preferred).

Working knowledge of designing parts for injection molding, over-molding, silicone injection molding, double-shot molding, die-cast metal, CNC, sheet metal, die-cut, and stamped processes.

Proven experience with tolerance stack-up analysis, GD&T, and resolving DFM/DFA/DFX feedback with tooling vendors.

Experience producing manufacturing-ready 2D drawings, BOMs, and clear engineering documentation.

Hands-on experience supporting EVT/DVT/PVT builds at Asia-based manufacturers, with willingness to travel to factory sites.

Self-motivated, collaborative, and effective in cross-functional teams under fast development schedules.

Strong communication skills with professional working proficiency in both English and Chinese.

Preferred Qualifications

Direct experience developing cameras, video doorbells, or similar connected-home devices.
