Lyft's Hardware Manufacturing & Quality team is looking for a Manufacturing Test Engineer to design, build, and manage the test systems that ensure every bike and scooter leaving our production lines is safe, durable, and functional. You'll own the software, electrical, and hardware test fixtures used on the factory floor, and you'll be the person production turns to when something breaks - whether that's a failing assembly or a misbehaving test station. Responsibilities: Test System Ownership • Design, build, and own the software, electrical, and hardware test fixtures used during production • Define the vision, strategy, and architecture for current and future manufacturing test systems, and author the test specifications and fixture acceptance plans that govern quality • Write scripts and programs to run automated tests and capture factory data for traceability and yield analysis • Implement features and tooling to support hardware testing across the product line • Own our in-house test platform: an OpenHTF-based Python execution runtime with YAML-driven config, product variants, and feature flags • Maintain the TypeScript/Electron/React operator application that communicates with the Python test agent over gRPC/protobuf • Manage CI, signed installers, semver releases, and an S3-based auto-update pipeline with rollback Hardware Bring-Up & Validation • Own firmware bring-up, validation, and testing of electronic PCBAs and multi-component electrical systems, including motor controllers, battery management systems, and vehicle-controller units • Validate mechanical and electrical assemblies to confirm they meet safety, durability, and functional requirements before they ship • Validate and troubleshoot factory tests, set factory test requirements, assist in software bring-up, and review test fixture software Production & Factory Floor Support • Be the eyes and ears on the ground in a manufacturing environment, partnering with engineers to triage issues, perform initial failure analysis, and drive corrective actions • Troubleshoot assembly failures on the production line and diagnose/fix bugs in test stations to keep the line running • Travel on-site to contract manufacturers as needed to ensure designs are built and tested successfully Cross-Functional & Vendor Leadership • Partner cross-functionally with contract manufacturers, supplier quality, and program teams to resolve manufacturing issues quickly • Maintain key relationships with manufacturing partner teams, internal and external test/lab resources, and mechanical, electrical, and manufacturing engineers • Manage external fixture vendors, including design reviews and Factory/Site Acceptance Testing (FAT/SAT) • Prepare concise, detailed design investigation summaries and test reports, and communicate cross-functionally to deliver successful products to market • Translate manufacturing requirements into terms enterprise IT and security teams can evaluate and support • Lead large test-engineering projects from concept through production execution Experience: • A degree in Electrical Engineering, Mechanical Engineering, Computer Engineering, Computer Science, or a related technical field • Experience with Python, C/C++, OpenHTF,TypeScript, or other scripting languages for test automation • Working knowledge of hardware test equipment (DMMs, oscilloscopes, logic analyzers, custom test fixtures) and lab tools such as soldering and data acquisition • Test fixture and station design and build. You have designed a functional test station and physically built it - instrument selection, DUT interfacing and harnessing, PLC control and power sequencing, enclosure and panel work, BOM specification and procurement. • Hands-on experience with prototype bring-up and debugging, functional verification, and manufacturing support • Experience with embedded systems design and communication protocols (CAN, USB, SPI, I2C, UART) • Experience with ARM-based microcontrollers and RTOS frameworks, preferably the STM32 family.Firmware programming and recovery experience (e.g., ST-LINK/STM32, AVR/ISP, bootloaders) • Strong troubleshooting instincts and comfort working directly on the factory floor Bonus Points • Experience with hardware test frameworks (e.g., OpenHTF,TypeScript, React, Electron, gRPC, protobuf, and SQLite) or building test platforms from scratch • Exposure to MES/ERP integration experience, including traveler, BOM, and label generation (ZPL/Zebra). • Exposure to Cloud data plumbing experience (S3, Lambda/SQS) and dashboarding in Grafana or Mode • Exposure to contract manufacturer (CM) relationships and global production ramps • Familiarity with test data pipelines, traceability, or genealogy systems • Familiarity with firmware debug tools, serial consoles, JTAG/SWD adapters, and bootloaders to support hardware validation • Experience with Android or embedded Linux environments, including building, deploying, and debugging • Willingness to travel to and work on-site at manufacturing and assembly vendors. Benefits: • Extended health and dental coverage options, along with life insurance and disability benefits • Mental health benefits • Family building benefits • Pet benefits • Access to a Lyft funded Health Care Savings Account • RRSP plan with company match to help save for your future • In addition to provincial observed holidays, salaried team members are covered under Lyft's flexible paid time off policy.
