Lead Manufacturing Test Engineer - Pcba & Rf Systems (Reynosa)

Job Title

Sr. Manufacturing Test Engineer

Responsibilities

• Lead and manage the manufacturing test engineering team, providing technical direction, prioritization and support across reflashing, functional test and NPI activities, ensuring consistent execution and team development.
• Oversee the execution of test processes at both PCBA and system level for network-enabled and RF-based products (e.g. gateways, communication modules and network devices), ensuring product validation aligns with design requirements and manufacturing expectations.
• Ensure proper firmware programming and reflashing of PCBAs and electronic modules, validating versions and configurations before product assembly and test execution.
• Define, implement and maintain test systems and fixtures used in manufacturing, including coordination with external suppliers when required, and ensure proper integration with production lines and test processes.
• Ensure each unit reaches the correct operational state prior to functional test execution, maintaining control of system behavior and avoiding invalid or misleading test results.
• Define and maintain the correct sequence between reflashing, system state, configuration and functional testing to ensure reliable and repeatable validation in production.
• Support and lead NPI activities from a test engineering perspective, working closely with design teams to define test requirements, align system behavior and transition initial builds into stable and scalable production processes.
• Troubleshoot and resolve production issues related to firmware, system state, communication, test systems and integration, minimizing downtime and supporting yield improvement.
• Analyze test results and production performance to identify trends, improve test reliability and drive continuous improvement of manufacturing processes.
• Coordinate with cross-functional teams including design engineering, production, quality and supply chain to ensure alignment between product requirements, test processes and manufacturing execution.
• Drive improvements in test architecture, coverage and reliability, ensuring that test processes remain efficient, scalable and aligned with product complexity.
• Ensure proper validation, release and control of test scripts and processes used in production, including pilot builds and production readiness activities.
• Work according to the Integrated Management System which includes ISO 9K, 18K, 14K, 27K, and ***** as applicable.

Required Experience

• Ensure products are validated under correct system conditions prior to release.
• Drive resolution of production issues related to firmware, system state, communication and test integration.
• Maintain stability and reliability of manufacturing test processes across NPI and production.
• Ensure alignment between test processes, product design and manufacturing execution.
• Bachelor's degree in electrical engineering, Electronics, Mechatronics or related field.
• 5+ years of experience in manufacturing test engineering within high-volume production environments.
• Hands‑on experience with PCBA and system-level testing, including firmware reflashing and functional validation of electronic and network-enabled products.
• Experience working with test systems and equipment for network and/or RF-based products (e.g. gateways, communication modules, network devices).
• Experience supporting NPI, including product introduction, test validation and ramp to production.
• Strong troubleshooting experience in manufacturing environments, resolving issues related to test systems, firmware, communication or product behavior.
• Experience leading or coordinating engineering teams or technical groups in a manufacturing environment.
• Experience working with external suppliers for test systems or fixture development is a plus.
• Experience with test software or automation tools (e.g. Python, LabVIEW, TestStand or similar) is preferred but not the primary focus of the role.

Required Abilities

• Strong understanding of manufacturing test processes for electronic and network-enabled systems, including PCBA-level and system-level validation.
• Solid experience working with firmware, including reflashing of PCBAs and electronic modules, as well as understanding how firmware, configuration and system behavior interact during production.
• Experience working with test systems and equipment used to validate network and RF-based products (e.g. gateways, communication modules and network devices), including setup, integration and troubleshooting on production lines.
• Practical knowledge of test fixtures, including definition, development and integration, as well as coordination with external suppliers when applicable.
• Strong troubleshooting skills in manufacturing environments, with ability to identify root cause of issues related to system state, configuration, communication or integration between hardware, firmware and test systems.
• Experience working with common system interfaces such as Ethernet, API-based communication, RF tools and other methods used to interact with embedded systems during test and configuration.
• Experience supporting NPI from a test engineering perspective, including defining test requirements, validating initial builds and transitioning processes into stable production.
• Ability to lead and develop engineering teams, providing technical direction, prioritization and guidance in day-to-day manufacturing and NPI activities.
• Strong cross-functional collaboration skills, working effectively with design, production, quality and suppliers to align test processes and product requirements.
• Ability to manage multiple priorities in a production environment, balancing NPI activities, production support and continuous improvement initiatives.
