Hardware & Firmware Development Engineers with PATENT TECHNICAL WRITER & AI ENGINEER/MOBILE APP DEVELOPER for Consumer-Grade Embedded IoT System
Budget: €3,000 – €5,000 EUR
We are seeking experienced Hardware and Firmware 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
FIRMWARE DEVELOPMENT ENGINEER
Key Responsibilities:
- Develop, optimise, and debug firmware for industrial IoT devices
- Integrate wireless communication protocols (Wi-Fi, BLE) and sensor systems
- Work with high-speed data interfaces and advanced wireless technologies
- Ensure seamless hardware-software integration and system reliability
- Collaborate with hardware teams for system bring-up and testing
- Participate in hardware validation and integration milestones
Required Qualifications:
- Proven experience with consumer electronics and mixed-signal designs (Hardware)
- Strong background in embedded firmware development for IoT devices (Firmware)
- Experience with wireless protocols (Wi-Fi, BLE) and sensor integration
- 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)
Firmware: 2-3 months
Both roles must coordinate closely throughout the development cycle
Note: Both engineers must strictly adhere to the milestone plan and deliverables. Clear communication and collaboration between hardware and firmware teams is essential for project success.
