Altium PCB Design Review by Remote -- 2

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.
