Role ResponsibilitiesSoldering, Rework and SMT Support
Perform hand soldering and rework on through-hole and surface-mount assemblies, including fine-pitch ICs, QFN and BGA-adjacent components, connectors, and RF shields, to IPC-A-610 Class 2 or Class 3 acceptance criteria.
Carry out board-level rework, including component replacement, pad and track repair, jumper wiring, and modification implementation against approved ECN and deviation notes.
Operate and maintain soldering stations, hot-air rework stations, preheaters, and desoldering equipment.
Control tip temperature, thermal profiles, and dwell time to protect boards and components.
Enforce ESD-secure working practices at every workstation, including wrist straps, mats, ionisers, and periodic verification logs.
Support SMT line output where required, including solder paste inspection, reflow profile verification, first-article review, and post-reflow defect assessment.
Firmware Flashing, Provisioning and Traceability
Execute production firmware flashing across the build using JTAG, SWD, UART, USB, or OTA methods,



as applicable to the product.
Operate and maintain programming jigs, bed-of-nails fixtures, pogo-pin adapters, and gang programmers.
Diagnose and resolve flashing failures at the fixture, cable, and target level.
Control firmware version integrity by ensuring the correct approved build is loaded against each work order.
Maintain firmware version traceability per serial number and prevent mixed-firmware batches from reaching dispatch.
Perform device provisioning activities, including serial number and MAC assignment, IMEI mapping, SIM configuration, calibration constant loading, security key or certificate injection, and server or APN configuration.
Coordinate with the firmware and embedded team on release handover, production build validation, and field-issue root cause analysis.
Provide structured failure feedback from the line back to engineering.
