Phone Repair Technician, Lagos (Nigeria)
On-site Lagos, Lagos, Nigeria
Location: Lagos, Nigeria
About the Role:
The Phone Repair Technician is to ensure that returned or repossessed phones are restored to full functionality quickly and reliably. The role involves diagnosing technical issues, performing component-level repairs, and carrying out quality control functions. You will handle both hardware and software-related problems, from replacing broken screens and batteries to troubleshooting operating system errors and connectivity issues.
Perform functional tests to triage damaged devices and diagnose failures
- Run diagnostic software/hardware checks on incoming devices (battery health, display, cameras, speakers/mic, sensors, buttons, charging port, Wi-Fi/Bluetooth/cellular)
- Sort and route devices by fault category and repair complexity (e.g., cosmetic-only, component swap, software issue)
- Flag devices that fall outside repair scope or are beyond economical repair (BER)
Disassemble, test, and replace defective components
- Safely disassemble devices using precision tools (spudgers, precision screwdrivers, heat guns/plates, suction tools) without damaging surrounding components
- Isolate faulty parts through component-level testing (multimeter checks, continuity tests, swap testing)
- Replace defective parts screens, batteries, cameras, charging ports, speakers, buttons with OEM approved components
Test and reclaim individual components and external housings
- Evaluate removed components (screens, batteries, cameras, small parts) for reuse potential
- Clean, refurbish, and re-certify housings, frames, and back covers for reuse where cosmetically and structurally acceptable
- Segregate reclaimed parts into inventory, and route non-reusable parts to scrap/recycling per policy
- Maintain accurate records of parts harvested vs. parts scrapped
Reassemble complete devices, following predetermined work instructions
- Follow model-specific SOPs/work instructions for reassembly sequence, torque specs, and adhesive/seal application
- Apply correct adhesives, gaskets, and shielding to maintain water/dust resistance ratings where applicable
- Verify that all components are fully seated before closing the housing.
- Ensure ESD-safe handling practices are followed throughout
Perform full functional, cosmetic, and RF testing
- Run complete post-repair diagnostics covering all functional systems (touch, display, audio, camera, sensors, battery charging/discharge)
- Conduct RF testing (cellular signal, Wi-Fi, Bluetooth, GPS) to confirm connectivity performance meets spec
- Inspect and grade cosmetic condition (housing, screen, ports) against company grading standards
- Document test results and assign final pass/fail/grade status before device moves to the warehouse
Identify potential areas for improvement of internal processes and procedures
- Flag recurring defects, part failure patterns, or workflow bottlenecks to team lead/supervisor
- Suggest improvements to work instructions, tooling, or test procedures based on hands-on findings
- Participate in root-cause discussions when rework or return rates spike
- Contribute to training/documentation updates as processes evolve
Manage inventory of spares and finished goods
- Log spare parts consumption in SAP at point of use (screens, batteries, cameras, connectors, etc.), linking each transaction to the correct device/work order
- Post finished goods (repaired/refurbished units) into SAP upon completion, with correct material code, grade, and storage location
- Process goods receipts for incoming spare parts and goods issues for scrapped/defective parts
- Participate in scheduled cycle counts and full stock takes, reconciling physical counts against SAP records before sign-off
- Investigate and correct stock discrepancies between SAP records and physical bin counts
- Monitor spare parts stock levels against min/max thresholds and raise replenishment/purchase requests in good time to avoid stock-outs
- Maintain FIFO/bin discipline and flag slow-moving, obsolete, or shortage-risk parts to the supervisor
- Bachelor’s degree or its equivalent, major in Electrical Engineering, Electronic Engineering, or a related field
- 2+ years’ direct experience in cell phone or other electronic device repair (mandatory)
- Experienced using precision tools and technology
- Have software flashing and RF test experience (preferred)
- Are a good team player with excellent time management
- Have high integrity and strong work ethic
- Professional growth in a dynamic, rapidly expanding, high-social-impact industry
