Hardware Development Engineers for Consumer-Grade Embedded IoT System

We are seeking experienced Hardware Development Engineers to lead the end-to-end development of a consumer-grade embedded IoT system. This is a collaborative project requiring close coordination between hardware and firmware teams to deliver a production-ready industrial IoT device with advanced wireless capabilities and sensor integration. HARDWARE DEVELOPMENT ENGINEER Key Responsibilities: - System-level hardware architecture and design freeze - Component selection (MCU/SoC, power ICs, storage interfaces, wireless modules) - Schematic design and PCB layout (high-speed + mixed-signal, EMI-aware) - Power integrity, grounding, shielding, and DFM/DFA compliance - Prototype fabrication support and manufacturer Q&A - Hardware bring-up support and validation with firmware engineer - Clear documentation for handover and future revisions Deliverables & Milestones: Milestone 1 – System Architecture & Design Freeze (10 days): - System block diagram - MCU/SoC selection with justification - Storage interface definition - Power budget & thermal assumptions - Preliminary BOM with cost estimates - Key risks & assumptions documentation Milestone 2 – Schematic Design + PCB Layout (14 days): - Complete Altium schematic and PCB layout - ERC/DRC-clean design - Stack-up and impedance details - Manufacturing files (Gerber, PnP, BOM) - Design notes (PDF + native files) Milestone 2-Extension – Prototype Fabrication Support: - Manufacturer Q&A support - Assembly file verification - Footprint/polarity confirmation Milestone 5 – Integration & Handover (7 days): - Schematics, PCB files, BOM handover - Bring-up notes - Hardware validation support - Test points/debug guidance Required Qualifications: - Proven experience with consumer electronics and mixed-signal designs (Hardware) - Strong background in Hardware development & comfortable with R&D for IoT devices - Experience with wireless protocols (Wi-Fi, BLE with low latency) and sensor integration - Good hold on codec - Prior experience with EU/US consumer products strongly preferred - Ability to work collaboratively across hardware-firmware boundaries - Strong documentation and communication skills Preferred Freelancer Locations: China, Japan, Taiwan, South Korea, Thailand, Vietnam, Eastern Europe, India Timeline: Hardware: Fixed by milestones as detailed above (approximately 31 days + fabrication support) Both roles must coordinate closely throughout the development cycle Note: Both Hardware & firmware engineers must strictly adhere to the milestone plan and deliverables. Clear communication and collaboration between hardware and firmware teams is essential for project success.
