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-protected 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.
