Hil Jobs in Washington (NOW HIRING)

AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we're 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 - and we're looking for talented people who want to help.
You'll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You'll 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 you'll 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 - 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
Design and build HIL test environments that replicate realistic datacenter loading scenarios - including power transients, thermal ramp events, cooling system interactions, and failure injection - enabling hardware and control systems to be validated under conditions that mirror Day 1 field deployment.
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.
Develop and execute integration test plans covering functional verification, stress testing, fault injection, and edge-case scenarios for FOAK products.
Define and maintain Design Verification Plans (DVPs) and acceptance criteria for integrated system behavior, covering thermal, electrical, mechanical, and control system interactions.
Automate HIL test workflows using Python, MATLAB/Simulink, or equivalent tools - enabling repeatable, scalable test execution and continuous integration of hardware validation into the product development cycle.
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.
Partner with cross-functional teams - including mechanical engineers, controls engineers, and electrical engineers to align on integration requirements, test coverage gaps, and deployment readiness criteria.
Build and maintain simulation-hardware co-validation frameworks - combining CFD/thermal models, electrical simulations, and physical test data to create high-confidence validation packages for new technology adoption.
Develop institutional HIL standards - repeatable test methodologies, rig architectures, signal interface specifications, and acceptance criteria - that scale across datacenter programs and product generations.
Support commissioning and operational readiness by translating HIL validation findings into field deployment guidance, operational runbooks, and risk mitigation strategies.
