The Amazon Center for Quantum Computing (CQC) team is looking to hire an Electrical Assembly & Testing Engineer. This role builds, tests, and calibrates delicate electronic components for cryogenic quantum computing systems. Candidates must have experience in precision electronics assembly, microelectronics integration, surface-mount (SMT) soldering and rework, and basic DC/RF measurements. The candidate will work with cryogenic RF/microwave systems, quantum processor electronics, and precision electrical test equipment. Responsibilities include precision soldering, rework, and assembly of PCBs populated with fine-pitch SMT components and RF connectors, as well as cable assemblies for cryogenic systems, following technical drawings while adhering to strict ESD and cleanliness protocols. The ideal candidate should have excellent fine motor skills, familiarity with basic electrical engineering principles, and strong problem solving and communication abilities. Working effectively within a team environment is critical. Key job responsibilities The primary responsibility of this role is precision electrical assembly and integration for cryogenic quantum computing operations. You will assemble, integrate, and package electro-mechanical components including PCB assemblies, cable assemblies, and quantum processors using specialized tools. You will perform high-quality hand soldering including connector attachment, SMT reflow, PCB rework, and assembly/routing of DC/RF harnesses/cables. Much of this work is done under a microscope: placing, reflowing, and reworking small SMT packages and miniature RF connectors, and inspecting the result against IPC workmanship standards. You will conduct electrical tests using multimeters, Vector Network Analyzers (VNAs), and automated test equipment to verify assembly performance through continuity, isolation, and transmission measurements. You will assemble components designed for high vacuum and cryogenic environments. You will follow detailed work instructions, update build logs, generate and update assembly procedures, inspect outside vendor assembly work, and maintain strict electrostatic discharge (ESD) safety protocols. A day in the life You will work across teams to assemble, integrate, test, and validate electrical systems for cryogenic quantum computing hardware. A typical week mixes bench work at the microscope, such as populating or reworking SMT components on cryogenic PCBs, with harness and cable fabrication, DC and RF testing, and documentation. You will read and interpret schematics, wiring diagrams, and technical procedures to execute precision assembly tasks. You will coordinate with stakeholders on electrical integration requirements, documentation, and scheduling. You will wire up qubit control electronic racks and contribute to developing new electrical assembly procedures while maintaining rigorous quality standards. The ideal candidate should embrace a fast-paced startup environment: they must be able to learn quickly, operate independently, communicate clearly, and consistently demonstrate reliability. About the team The Amazon Center for Quantum Computing (CQC) is a multi-disciplinary team of scientists, engineers, and technicians, on a mission to develop a fault-tolerant quantum computer.
