Senior Product Test Engineer

Locus Robotics designs and deploys autonomous mobile robots (AMRs) that work alongside human associates in warehouse and fulfillment environments to dramatically increase picking efficiency and throughput. Our LocusBots navigate complex, dynamic warehouse floors and integrate tightly with warehouse management systems to drive real operational results for some of the world's largest retailers and 3PLs. As we scale our hardware platform, we need sharp engineers who can ensure every robot that leaves our factory is ready to perform from day one.

We’re looking for a Senior Product Test Engineer to own and optimize end-of-line testing for our autonomous robots, ensuring high quality, reliability, and manufacturing efficiency at scale.

This is an onsite position located at our Wilmington MA headquarters.

Responsibilities

• Own and improve end of line test infrastructure for LocusBot subassemblies and fully integrated robots, including software, calibration, and functional verification
• Develop and maintain automated test sequences that validate drivetrain, sensor, compute, and power systems against defined acceptance criteria
• Spend regular time on the manufacturing floor to understand technician pain points, investigate test failures, and implement solutions that improve first-pass yield (FPY) and reduce cycle time
• Collaborate cross functionally with mechanical, electrical, and software engineering teams to translate design intent into robust, measurable test specifications
• Perform data analysis (SPC, yield trending, failure mode analysis) to identify systemic quality issues and drive continuous improvement
• Build intuitive GUI interfaces for production technicians to operate test stations with minimal training overhead
• Design and build out of new test fixtures and automated test equipment (ATE) as the product line evolves
• Author and maintain thorough documentation for all test systems, including schematics, process procedures, and test result databases
• Support pre production validation, debug efforts, and readiness before introducing new test process to the production environment

Qualifications

• Bachelor's degree or higher in Electrical, or Software Engineering, or Mechatronics Engineering (or equivalent experience)
• 6+ years of hands-on industry experience in manufacturing test, production engineering, or a closely related discipline
• Strong proficiency in Python (or nice to have: C++) for hardware interfacing actuators, motor controllers, sensors, relays, and power systems
• Comfortable working in a Linux environment, including Bash scripting and command line debugging
• Ability to read and interpret electrical schematics and PCB layouts to diagnose hardware failures at the component level
• Familiarity with Networking Foundations and Database Management
• Experience in scaled production environments and hardware lifecycle management
• Solid experience with embedded communication protocols: Ethernet, USB, SPI, UART, SCPI, and CAN bus
• Demonstrated understanding of software engineering best practices version control, code review, modular design, and test-driven development
• Experience with data acquisition hardware and industrial I/O devices (e.g., power meters, current sensors, DAQ cards)
