Sobre
You will be the senior technical point of contact for a large wearable ecosystem in the field, supporting around ten thousand devices and hundreds of smart stations deployed globally. This is a hands on support QA role focused on root cause analysis across firmware, hardware, software, and connectivity, working with customers, support, and manufacturing rather than classic product feature QA.Tasks and deliverables
- Act as a senior support QA engineer for wearables and smart stations deployed globally, with a focus on devices in Mexico and surrounding regions.
- Investigate complex field issues reported from customers, support, and sales teams, involving firmware, hardware, software, connectivity, antennas, and user behavior.
- Collect and analyze logs from Linux based devices (for example journalctl, dmesg, system logs) and related backend systems.
- Reproduce, isolate, and triage issues across multiple layers: firmware, hardware, networking, and mobile / client applications.
- Provide clear troubleshooting guidance for internal teams and customers, including step by step instructions to collect data and logs.
- Work closely with manufacturing and production teams to analyze failures, identify patterns across units (for example firmware version, batch, serial number), and support root cause investigations.
- Maintain traceability and follow up for RMAs and critical incidents, ensuring proper documentation of root cause and corrective actions.
- Collaborate with engineering teams to prioritize and communicate field issues, including preparing concise, data rich incident reports.
- Use internal APIs and tools (for example AWS based dashboards) to correlate device data, events, and configurations across manufacturing and field environments.
- Participate in on site visits when needed to better understand operational environments and assist with complex troubleshooting.
Engagement highlights
- High impact role supporting a large, globally deployed wearable ecosystem.
- Unique combination of QA engineering mindset and real world field support, not typical feature testing.
- Opportunity to work across the full stack of the product: hardware, firmware, connectivity, and user environments.
- Close collaboration with customers, support, sales, and manufacturing to drive real improvements in reliability and user experience.
- Mix of remote analytical work and occasional on site troubleshooting, keeping the role varied and engaging.
