We are looking for a Senior Electronics Technician to support the development, bring-up, and validation of the electronic systems that power our robots. This role sits at the bench alongside our electrical, embedded, and mechanical engineers, turning new designs into working hardware and helping us find the failure modes before our customers do. You will be hands-on every day with prototype PCB - As, motor drivers, battery systems, and full-robot integration, and your work will directly shape the quality and reliability of the platform. Key job responsibilities- Build, rework, and repair prototype and early-production PCB - As, including fine-pitch SMT components, BGAs, QF - Ns, 0201 passives, and flex circuits - Execute electrical bring-up and functional test procedures on new boards and subsystems, capturing results clearly and feeding issues back to design - Assembling low run SMT PC - Bs working from ECAD schematics in Altium or Ki. CAD - Debug hardware problems at the bench using oscilloscopes, logic analyzers, DM - Ms, power analyzers, and protocol decoders, working from schematics and PCB layouts to isolate root cause - Develop, refine, and maintain test fixtures, jigs, and bring-up scripts in partnership with E - Es and embedded engineers - Support battery pack assembly, instrumentation, and characterization, including cell-level and pack-level testing - Perform incoming inspection and first-article evaluation on components and assemblies from our contract manufacturer and component vendors - Support full-robot integration and electrical commissioning, including harness build, continuity and hipot checks, and powered bring-up - Document work clearly: rework notes, test reports, work instructions, ECO redlines, and traceable records of build configuration - Partner with manufacturing and quality to transfer test procedures and rework standards into production, and to debug failures returned from the line - Maintain the electronics lab: equipment calibration, ESD compliance, inventory of consumables and reference hardware, and general bench hygiene - Mentor junior technicians on soldering technique, debug methodology, and lab safety About the team. Fauna Robotics, an Amazon company, is building capable, safe, and genuinely delightful robots for everyday life. Our goal is simple: make robots people actually want to live and interact with in everyday human spaces. We believe that future won't arrive until building for robotics becomes far more accessible. Today, too much effort is spent reinventing the fundamentals. We're changing that by developing tightly integrated hardware and software systems that make it faster, safer, and more intuitive to create real-world robotic products. Our work spans the full stack: mechanical design, control systems, dynamic modeling, and intelligent software. The focus is not just functionality, but experience. We're building robots that feel responsive, expressive, and genuinely useful. At Fauna, you'll work at the frontier of this space, helping define how robots move, manipulate, and interact with people in natural environments. It's an opportunity to solve hard problems across hardware and software with a team focused on making robotics accessible and joyful to build. Basic Qualifications- Experience working with interdisciplinary teams to execute product design from concept to production- 7 years of hands-on electronics technician experience in a hardware development environment (robotics, consumer electronics, aerospace, medical, automotive, or similar)- IPC-A-610 and IPC J-STD-001 knowledge at a working level; IPC 7711/7721 rework experience- Expert fine-pitch hand soldering and rework, including BGA reball/replacement, QFN, 0201 and smaller passives, and flex assemblies, using hot air, IR, and microscope stations- Proficient reading multi-sheet schematics and multi-layer PCB layouts to trace signals, identify test points, and plan rework- Expert use of oscilloscopes (including differential and high-bandwidth probes), logic analyzers, protocol decoders, DM - Ms, electronic loads, and bench power supplies- Working knowledge of common embedded interfaces (CAN/ CAN FD, SPI, I 2 C, UART, RS 485, USB, Ethernet) and how to capture and interpret them on the bench- Disciplined ESD practice and general electrical safety habits, including working safely around lithium-ion battery packs and higher-voltage DC - Preferred Qualifications- Experience with robotics, motor drives, or other real-time electromechanical systems- Experience with lithium-ion battery pack build, instrumentation, or characterization- Familiarity with Python or similar scripting for test automation and data capture- Experience building and maintaining custom test fixtures- IPC certifications (CIS or CIT) in J-STD-001 and 7711/7721- Experience with EMI/ EMC pre-compliance testing in a lab setting- Associate's degree in electronics technology or equivalent military/trade school/professional training.
