As a **Hardware Engineering - Sustaining,** your role is to keep the in-market fleet healthy, understanding, getting to RC, and resolving any product issues. • Field-issue root cause - 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. • ECO / revision management - manage engineering change orders, PCB respins, and component substitutions (e.g. converter/regulator swaps, fuel-gauge/charger changes); maintain revision traceability across the fleet. • Component & supplier issues - handle EOL, second-sourcing, and vendor quality escalations; author and drive supplier 8D/SCAR corrective actions (batch defects, separator/assembly issues). • Manufacturing support - support Luxshare (Kunshan/Vietnam) with production issues, yield analysis, DFM feedback, and FATP/SMT line support; assist the CM shift for US-market products. • RMA / refurb - own the RMA and refurbishment engineering path; feed field-failure patterns back into design and verification. • Cross-pod triage - act as first responder for sustaining issues across all product lines, escalating to the owning pod only when new design work is required. **Our ideal candidate must have:** • 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. **Strongly preferred** • 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. **Compensation:** $100,000 - $150,000 base salary The specific pay offered may be influenced by a variety of factors, including the candidate's experience, education, and skill set. **What does Tive offer?** • A chance to join what may very well turn out to be the most important company in your career. • The autonomy and resources to build what you know how to build. • Work with a committed global team that have each others back. • Office-based or hybrid options. Your choice. • Competitive equity to ensure all of our employees have a sense of ownership in the long-term success of Tive's growth.
