Job Title

DescriptionAWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, weu2019re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain u2014 and weu2019re looking for talented people who want to help. Youu2019ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. Youu2019ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And youu2019ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion. As a Systems Integration Engineer, with deep expertise in Hardware-in-the-Loop (HIL) testing, you will serve as the critical bridge between software simulation environments and physical hardware u2014 ensuring that control systems, firmware, and mechanical infrastructure perform as designed before field deployment. You will own the end-to-end integration validation lifecycle: from defining test architectures and building HIL rigs, to executing closed-loop testing that replicates real-world datacenter operating conditions. Your work will directly prevent costly field failures, accelerate FOAK product deployment, and build institutional validation frameworks that scale across our global datacenter programs. If you are passionate about innovative projects at hyper-scale and meet these qualifications, this role is for you Key job responsibilities u2022 Design and build HIL test environments that replicate realistic datacenter loading scenarios u2014 including power transients, thermal ramp events, cooling system interactions, and failure injection u2014 enabling hardware and control systems to be validated under conditions that mirror Day 1 field deployment. u2022 Own the integration layer between physical hardware (mechanical systems, electrical infrastructure, sensors, actuators) and software simulations ensuring bidirectional signal fidelity and realistic closed-loop behavior. u2022 Develop and execute integration test plans covering functional verification, stress testing, fault injection, and edge-case scenarios for FOAK products. u2022 Define and maintain Design Verification Plans (DVPs) and acceptance criteria for integrated system behavior, covering thermal, electrical, mechanical, and control system interactions. u2022 Automate HIL test workflows using Python, MATLAB/Simulink, or equivalent tools u2014 enabling repeatable, scalable test execution and continuous integration of hardware validation into the product development cycle. u2022 Lead Root Cause Analysis (RCA) on integration failures by reproducing failure modes in the HIL environment, isolating hardware vs. software root causes, and producing data-backed reports that support deployment sign-off decisions. u2022 Partner with cross-functional teams u2014 including mechanical engineers, controls engineers, and electrical engineers to align on integration requirements, test coverage gaps, and deployment readiness criteria. u2022 Build and maintain simulation-hardware co-validation frameworks u2014 combining CFD/thermal models, electrical simulations, and physical test data to create high-confidence validation packages for new technology adoption. u2022 Develop institutional HIL standards u2014 repeatable test methodologies, rig architectures, signal interface specifications, and acceptance criteria u2014 that scale across datacenter programs and product generations. u2022 Support commissioning and operational readiness by translating HIL validation findings into field deployment guidance, operational runbooks, and risk mitigation strategies. About the team Why AWS Amazon Web Services (AWS) is the worldu2019s most comprehensive and broadly adopted cloud platform. We pioneered cloud computing and never stopped innovating u2014 thatu2019s why customers from the most successful startups to Global 500 companies trust our robust suite of products and services to power their businesses.
