Job description

Mechanical Design Engineer (3D Design Focus)

Mechanical Design Engineer (3D Design Focus)

Location: Birmingham, AL (On-site)
Compensation: DOE + Full Benefits
Travel: ~10%

Overview

A growing industrial automation and custom equipment company is seeking a Mechanical Engineer with proven 3D design experience to join its engineering team. This is not an entry-level role—the ideal candidate will be capable of jumping in on day one and owning mechanical design responsibilities across active projects.

This position is highly design-focused and suited for someone who has already worked in a manufacturing, automation, or machinery environment and is comfortable creating production-ready models, drawings, and assemblies without extensive ramp-up time.

What You’ll Be Doing

3D Mechanical Design (Core of the Role)

Design complex mechanical systems, assemblies, and components using SolidWorks (or similar CAD)

Develop detailed 3D models, fabrication drawings, and fully structured BOMs

Create production‑ready designs that account for manufacturability, tolerances, and real‑world application

Own designs from concept through release—this is a hands‑on design role, not a support position

Work closely with electrical, controls, and applications teams to deliver fully integrated systems

Support builds, troubleshooting, and system validation during shop and field phases

Assist with installation support and real‑time problem solving as needed

Testing & Quality

Participate in design reviews, identifying issues before release to production

Support FAT/SAT activities and ensure systems meet performance expectations

Continuously refine and improve existing designs for efficiency and reliability

Documentation & Communication

Maintain clean, organized CAD files and revision control

Generate clear technical documentation for internal teams and external stakeholders

Communicate effectively with vendors, machinists, and internal build teams

What We’re Looking For

Experience (Non‑Negotiable)

3+ years of hands‑on mechanical design experience in automation, manufacturing, or industrial equipment

Proven ability to independently create complex 3D designs from scratch (not just modify existing models)

Technical Skills

Advanced proficiency in SolidWorks or similar 3D CAD platform

Strong understanding of mechanical systems, materials, and fabrication methods

Experience designing for real‑world conditions (assembly, stress, wear, manufacturability)

Ability to read and interpret mechanical and electrical schematics

Working knowledge of pneumatics, hydraulics, and structural components

Preferred Background

Automation systems, robotics, or custom machinery design

Experience working closely with shop teams or on prototype builds

What This Role Is NOT

Not an entry‑level or training‑heavy position

Not a drafting‑only role—this is true engineering design ownership

Not a sales or customer‑facing commercial role

Not a project management position (though collaboration is key)

Split between engineering office and active shop floor

Hands‑on involvement with builds, testing, and troubleshooting

Occasional travel for system validation or field support (~10%)

$65K – $105K base salary (depending on experience)

401(k) with company match

Health, dental, and vision insurance

Paid time off

Why This Opportunity Stands Out

Strong collaboration with cross‑functional engineering teams

Opportunity to grow into senior or lead design roles
