The Amazon Web Services Center for Quantum Computing (CQC) in Pasadena, CA, is looking to hire an Applied Scientist. You will join a multi-disciplinary team of experimental and theoretical physicists, materials scientists, and hardware and software engineers working at the forefront of quantum computing. You should have a solid foundation in experimental physics and deep and broad knowledge of experimental measurement techniques. 

Candidates should have a track record of original scientific contributions, and those with deep knowledge and experience in low temperature condensed matter physics (superconductivity, Josephson junctions, phononics, TLS physics etc.) will be preferred. We are looking for candidates with strong engineering principles, resourcefulness and a bias for action, superior problem solving, and excellent communication skills. Working effectively within a team environment is essential. You will be expected to work on new ideas and stay abreast of the field of experimental quantum computation. Key job responsibilities In this role, you will be part of the Physical Metrology and Exploration (PME) subgroup within the Device team. You will work with the basic building blocks of quantum processors, ranging from superconducting films and resonators to junctions and qubits. There are two core missions for the PME team. The first is to support the CQC’s central activities through the development of devices, both existing and novel, that fall within this complexity range. This involves understanding their physical principles, identifying performance limitations, and collaboratively enhancing their capabilities. In many cases though, existing tools and measurement protocols fall short in delivering the depth of insights required for this first mission. Hence the second core mission of the team centers on physical metrology development. This involves continuously refining existing methodologies and simultaneously devising entirely new ones by identifying specific physical phenomena and exploiting them for measurement applications. You will constantly learn, innovate, carry out agile and yet scientifically rigorous research, and disseminate findings to the rest of the organization. You will be responsible for building experiments that encompass the integrated stack: design, fabrication, cryogenics, signal chain, and control stack software. Based on your research, you will provide recommendations that improve our next-generation quantum processors.

Payroll Tech's Sheriff team develops and maintains ML and Generative AI applications that support Payroll Operations and Amazon employees at scale. Our portfolio includes Pay-Input Anomaly Detection, which improves the pay experience by identifying pay input irregularities such as leaves and insurance discrepancies; Percept, which improves ticket resolution by providing intelligent ticket prioritization via sentiment scoring, ticket summarization, defect classification, and categorization; Penny, a Virtual Assistant that enables payroll operations teams to efficiently retrieve information from multiple sources including policies, Percept data, vendor data, and HR data via Xylem through a single browser interface; Pay Ticket Genie, in process of being integrated with Amazon AZA(A to Z Assistant); Niyam, our rule engine; and Policy as Code Extraction (PoCo), a critical component of SPACE (Single Payroll Autonomous and Computation Engine) Amazon's in-house payroll system built to eliminate third-party vendor dependency for payroll processing. PoCo ensures data accuracy by validating that pay instructions are correct and performing calculations when required. It consists of two components: policy-based rule creation, where business owners select a pay code and provide policy links to generate rules for specific business processes, and rule evaluation, where upstream services send real-time validation or calculation requests and receive results along with rationale for any failures. Sheriff team owns policy-based rule creation and powering the rule evaluation system with rules generated. As an Applied Scientist on the Sheriff team, you will own and advance the ML and GenAI capabilities that power these systems: driving model accuracy, scientific innovation, and global scale across the payroll ecosystem. Key Job Responsibilities As an Applied Scientist on the Sheriff team, you will operate across three core dimensions: Invent, Implement, and Influence. Invent You bring deep domain knowledge and fluency with state-of-the-art scientific approaches as well as emerging technologies from the research community. You practice customer-obsessed science : working backwards from the needs of Amazon employees and payroll operations teams to extend or invent new ML approaches, even when no textbook solution exists. You design novel ML and LLM-based methodologies for anomaly detection, sentiment analysis, ticket classification, prescriptive analysis, intelligent virtual assistance, and automated policy extraction. You identify and define the research agenda for expanding Percept's capabilities including prescriptive analysis feature; lead the scientific strategy for the Penny-AZA integration enabling accurate and low-latency responses to Amazon employee payroll queries, and drive the ML strategy for Policy as Code extraction(PoCo), developing models that extract, interpret, and codify payroll policies into structured, executable rules that power real-time pay instruction validation and calculation within SPACE. You author or co-author articles for internal or external peer-reviewed venues that validate the novelty of your work, when appropriate and not precluded by business considerations. Implement The ML components you develop are directly integrated into production systems or directly support large-scale applications serving Amazon's global payroll operations. You make appropriate tradeoffs between model accuracy and latency, innovation and stability, and immediate versus long-term solutions; favoring reuse and established frameworks where appropriate. You make progress semi-autonomously with only occasional guidance, implement at the correct level of complexity the first time, and evaluate emerging technologies including Large Language Models (LLMs) and GenAI frameworks largely on your own. You ensure your models and pipelines integrate robustly with data sources including USC (Unified Central Service), Xylem, SIM-Ticketing, Pay Code Governance system, and PoCo's rule evaluation engine. Influence You contribute to tactical and strategic planning for the Sheriff team, including goals, priorities, and roadmaps for ML and GenAI capabilities. You lead the scientific strategy for the global expansion of Percept, driving both feature growth and country-level launches own the complex AI track for Penny-AZA integration collaborating across partner teams including Reflect and GREF to ensure seamless data integration and robust ML pipeline workflows, and drive the scientific roadmap for PoCo's expansion to 100K US employees, ensuring the ML models powering policy extraction, rule generation and testing scale reliably to meet this growth. You mentor scientists and engineers on the team and across teams, championing best practices for the AI-Driven Development Life Cycle (AIDLC) to rapidly increase developer productivity and delivery velocity. You provide peer feedback on research procedures and results within and across teams, help recruit and develop bar-raising talent through interview drives, and grow the team's organizational knowledge of Sheriff team ML solutions. You are visible in the broader internal and external scientific communities as a subject matter expert and regularly serve as a Program Committee (PC) member at peer-reviewed conferences or review articles for journal publications.
