Senior Automotive Mechanical Engineer for Reverse Engineering and Complete OEM Technical Drawing Package Anyone

# Reverse Engineering & Complete Automotive Technical Drawing Package

## Project Overview

We are seeking an experienced **Senior Mechanical Design / Automotive Product Design Engineer** to reverse engineer an existing physical automotive accessory and produce a **complete OEM-level engineering drawing and CAD package**.

A physical production sample will be provided for inspection, measurement and disassembly.

This project is **not simply 3D scanning or creating an external CAD model**. The selected engineer must be capable of documenting the complete product down to component level and producing engineering drawings suitable for **automotive OEM design review and approval**.

The product is a relatively simple mechanical automotive accessory consisting primarily of molded plastic components, reflective/material components, rubber parts, fasteners and mechanical joints.

## Scope of Work

The selected engineer will be responsible for:

### 1. Physical Product Reverse Engineering

* Inspect and disassemble the provided production sample as required
* Measure overall and component-level geometry
* Identify all individual components and their interfaces
* Determine dimensions, radii, angles, thicknesses, hole/slot geometry and other relevant features
* Identify fastening and assembly methods
* Identify critical mating/fit dimensions
* Coordinate 3D scanning/CMM measurement if necessary

Please indicate whether you have your own measurement/scanning capabilities or would require us to arrange external metrology services.

### 2. Complete 3D CAD Model

Create:

* Individual 3D CAD models for all custom components
* Complete parametric 3D assembly
* Accurate mating/positioning of components
* Exploded assembly
* STEP export
* Native editable CAD source files

SolidWorks, CATIA or Siemens NX experience is preferred.

### 3. Assembly / General Arrangement Drawing

Produce a detailed assembly drawing showing, as applicable:

* Front, side, top and other required views
* Overall dimensions
* Relevant radii and angles
* Product thicknesses
* Centerlines/datums/reference points
* Section and cross-sectional views
* Component callouts
* Assembly relationships
* Installation/operating configuration
* Product mass
* Material and surface-treatment information
* Relevant engineering notes

### 4. Individual Component Drawings

Produce detailed drawings for all relevant custom components, including:

* Molded plastic parts
* Rubber feet/pads
* Reflective/material components
* Metal parts
* Hinges/pivots/joints
* Pins and similar hardware
* Labels/markings
* Other custom components

Each drawing should contain sufficient engineering information to fully define the component.

### 5. Fasteners & Assembly Details

All screws, bolts, nuts and other fasteners must be properly identified and specified, including where applicable:

* Fastener type
* Diameter
* Length
* Thread specification/pitch
* Head type
* Material/finish
* Quantity
* Installation/interface details

Relevant sections should show how components are mechanically joined and fitted together.

### 6. Dimensions, Tolerances & GD&T

The engineer should apply professional engineering judgment to define:

* Complete dimensional information
* General tolerances
* Critical dimensional tolerances
* GD&T where appropriate
* Datums where appropriate
* Fit/clearance requirements
* Mating/interface dimensions
* Critical assembly dimensions

The objective is not merely to report measured dimensions but to convert the physical product into a properly defined engineering design.

### 7. Bill of Materials

Prepare a complete BOM containing, where applicable:

* Item number
* Component/part name
* Quantity
* Part identification
* Material
* Size/specification
* Mass
* Color
* Surface treatment/finish
* Remarks

### 8. Materials & Product Specifications

Document known or reasonably identifiable:

* Plastic/resin materials
* Rubber/elastomer materials
* Metal materials
* Reflective/material components
* Surface treatments
* Colors
* Component mass
* Product mass

Where exact material composition or properties cannot be determined from physical examination, clearly identify what additional material/laboratory testing would be necessary rather than making assumptions.

### 9. Engineering / Compliance Notes

The drawing package should provide appropriate locations and engineering notes for applicable:

* Performance requirements
* Evaluation/test requirements
* Regulatory requirements
* Material requirements
* Flammability requirements
* Product marking requirements
* Manufacturing requirements
* Color requirements
* Other product-specific requirements

Confidential customer-specific standards and evaluation requirements will be handled separately and incorporated as required during finalization.

## Required Deliverables

Final deliverables should include:

* Complete 3D CAD assembly
* Individual 3D component models
* Native editable CAD files
* STEP files
* Complete 2D engineering drawing package in PDF
* Editable 2D drawing files
* Overall assembly drawing
* Exploded assembly drawing
* Individual component drawings
* Section/cross-sectional drawings
* Complete BOM
* Relevant tolerance/GD&T definitions
* Material/component specifications
* Engineering/manufacturing notes

The completed package should be suitable for submission to an **automotive OEM engineering department for technical/design review**.

## Preferred Experience

We are particularly interested in engineers with experience in:

* Automotive component/product design
* Automotive OEM drawing standards
* Reverse engineering from physical samples
* CATIA / Siemens NX / SolidWorks
* GD&T
* JIS / ISO engineering drawing standards
* Injection-molded plastic components
* Rubber/EPDM components
* Mechanical assemblies and fasteners
* Automotive BOM creation
* Design review documentation
* Manufacturing drawings


## Information to Include in Your Proposal

Please provide:

1. Relevant automotive design/reverse-engineering experience
2. Examples of similar **assembly and component-level engineering drawings** you have produced (confidential information may be redacted)
3. CAD software you use
4. Experience with GD&T and automotive drawing standards
5. Experience with injection-molded plastic and rubber components
6. Experience creating complete BOMs and manufacturing documentation
7. Your physical measurement/reverse-engineering methodology
8. Whether you have access to CMM, 3D scanning or other metrology equipment
9. Whether you are located in the Philippines and can receive/inspect a physical sample
10. Estimated project lead time
11. Proposed project fee

## Important

We are specifically looking for an **engineer with product-development and automotive drawing experience**, rather than a general CAD draftsman.

The successful candidate must be capable of taking an existing physical product and developing a **complete engineering definition of the product at assembly and individual-component level**, with the level of detail expected in an automotive OEM technical drawing package.

Due to customer confidentiality, proprietary OEM drawings, internal standards and customer-specific test requirements cannot be provided during the initial quotation stage. Additional controlled information may be provided to the selected engineer as appropriate. read less
