About The Position

As a Hardware Engineering - Sustaining, your role is to keep the in-market fleet healthy, understanding, getting to RC, and resolving any product issues. This involves owning the investigation of returns and field failures, driving root-cause analysis to closure, managing engineering change orders, PCB respins, and component substitutions, handling component and supplier issues including EOL and second-sourcing, supporting manufacturing with production issues and yield analysis, owning the RMA and refurbishment engineering path, and acting as the first responder for sustaining issues across all product lines.

Requirements

BS/MS in Electrical Engineering or equivalent, with 4+ years in hardware sustaining, NPI, or manufacturing engineering for high-volume electronics.
Solid grasp of schematic and PCB design review — able to read a design, reason about a power tree, and assess a proposed change's risk.
Direct experience with contract manufacturers: DFM, yield, FATP/SMT, and production issue resolution.
Structured root-cause discipline (8D/5-Why/fishbone) and the follow-through to close corrective actions with suppliers.
Comfortable owning ambiguous, cross-cutting problems in a distributed team.

Nice To Haves

Low-power / battery-powered IoT hardware background; familiarity with cellular + GNSS + BLE devices.
Hands-on with the platform silicon class: ESP32-class MCUs, cellular modems (SIMCom/Quectel), fuel gauges and chargers, IMUs, and buck-boost regulators.
Mandarin and/or China-based experience for CM coordination (a plus, not required).
Experience feeding sustaining insight back into verification and design so recurring issues get designed out.

Responsibilities

Own investigation of returns and field failures (e.g. crash-reset/brownout loops, registration failures, latent battery shorts); drive root-cause analysis to closure with clear confirmed-vs-inferred findings.
Manage engineering change orders, PCB respins, and component substitutions (e.g. converter/regulator swaps, fuel-gauge/charger changes); maintain revision traceability across the fleet.
Handle EOL, second-sourcing, and vendor quality escalations; author and drive supplier 8D/SCAR corrective actions (batch defects, separator/assembly issues).
Support Luxshare (Kunshan/Vietnam) with production issues, yield analysis, DFM feedback, and FATP/SMT line support; assist the CM shift for US-market products.
Own the RMA and refurbishment engineering path; feed field-failure patterns back into design and verification.
Act as first responder for sustaining issues across all product lines, escalating to the owning pod only when new design work is required.
