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
• An open-minded, collaborative culture made up of enthusiastic colleagues who are driven by the challenge of innovation towards profound impact on people and the planet.
• A truly multicultural experience: you will have the chance to work with and learn from people from different geographies, nationalities, and backgrounds.
• Structured, tailored learning and development programs that help you become a better leader, manager, and professional through the Sun Center for Leadership.
