Altium PCB Design Review by Remote

Freelance Hardware Engineer – Altium PCB Design Review (Remote Access)

We have an existing Pulse Converter PCB designed using Altium Designer and are looking for an experienced freelance hardware / PCB design engineer to perform a technical design review.

The work will be done via remote access to our computer (AnyDesk / TeamViewer). Design files will not be shared.
Detailed circuit functionality and design context will be explained after mutual agreement and confidentiality alignment.

Scope of Work:
Review the schematic and PCB layout in Altium Designer and identify potential design issues, risks, and improvement points, including but not limited to:

Power input and regulation (wide-range DC input)

Relay driver circuits

Optocoupler-based pulse input circuits

MCU (ESP32 or similar) pin usage and protection

Grounding and power plane strategy

EMI / ESD risks

Trace width, clearance, creepage distances

Manufacturability and field reliability concerns

Provide clear, actionable technical feedback and, if needed, revision recommendations.

Requirements:

Strong experience with Altium Designer

Proven PCB design experience with MCUs (ESP32 or similar)

Experience with industrial-grade hardware design

Knowledge of relay, optocoupler, and high-voltage tolerant circuits

Understanding of power integrity, EMI / ESD considerations

Comfortable working via remote desktop tools

Working Model:

Remote, confidentiality-focused engagement

Design review via screen sharing only

Estimated duration: 1–3 sessions (depending on complexity)

Compensation to be agreed based on experience

Application Requirements:

Brief professional background or profile link

Examples of previous PCB / hardware projects

Years of experience with Altium Designer

Availability (days / hours)

Note:
This task is limited to design review and technical assessment. If collaboration is successful, additional work such as design revisions or new PCB development may follow.
