Senior Mechanical Engineer – IoT Product Design (Part-Time)

Mechanical Engineer – Ruggedized IoT Product Design (Project-Based)

Location: Austin, Texas (Local preferred)

Engagement: Project-based

Role Overview

We are looking for an experienced mechanical engineer to lead the design and implementation of next-generation rugged IoT enclosures and tooling. This role replaces the need for a third-party design agency and requires hands-on experience bringing industrial products from concept to production.

Key Responsibilities

Design ruggedized enclosures for outdoor/industrial environments (IP-rated).

Develop packaging and internal mechanical architecture for PCB assemblies, antennas, and battery systems.

Select materials suitable for UV, thermal, vibration, and corrosion exposure.

Manage tooling design (injection molding, die casting, CNC components).

Conduct tolerance stack-up, FEA, and thermal analysis.

Work directly with contract manufacturers for DFM and cost optimization.

Support certification requirements (UL, ingress protection, impact ratings).

Qualifications

3+ years mechanical product design experience in industrial or IoT hardware.

Strong proficiency in SolidWorks (or equivalent CAD).

Experience with injection-molded plastics and gasket sealing design.

Demonstrated track record of successful production tooling launches.

Knowledge of antenna integration constraints is a plus.
