The range of process fluids is broad (liquid, gaseous, cryogenic, supercritical, molten salt, etc.), requiring strong mechanical and chemical engineering fundamentals. The ideal candidate will be resourceful-combining industry best practices, off-the-shelf and customized hardware, and creativity to deliver these fluid systems on tight timelines. Projects will be on varying scales, from smaller-scale test stands and deep system analysis to larger, complex projects as needed for SPARC and ARC. In addition to designing and building, the engineer will actively operate as a test engineer to commission systems and design automation alongside a team of test/software engineers and operators. You must work collaboratively across production, R&D, procurement, and the SPARC team. Various projects will also require flexing outside of traditional fluids engineering into other disciplines, such as structures and materials engineering, to successfully retire risks for SPARC and ARC., * Design fluid systems for test stands that meet test objectives/requirements, soliciting feedback from interfacing teams as necessary * Challenge requirements as necessary to achieve simplicity in design and develop efficient de-risking strategies and plans * Perform hand calculations and system level analyses demonstrating sufficient margin for fluid system requirements; build and run Ansys structural and thermal simulations on components and assemblies * Procure off-the-shelf process fluid components, manage relationships with vendors, draft specifications for speciality parts and design custom fluid system components as needed * Manage the build and commissioning of fluid systems, coordinating engineers and technicians to safely bring systems to operational status * Design system instrumentation and automation for safe operations ## Related Videos - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Cloud Vendor Lock-In - Is it just a new version of the Database Abstraction Layers?](https://www.wearedevelopers.com/videos/1185-cloud-vendor-lock-in-is-it-just-a-new-version-of-the-database-abstraction-layers) - [Strange New Worlds: shaping the future of the digital age](https://www.wearedevelopers.com/videos/677-strange-new-worlds-shaping-the-future-of-the-digital-age) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Colorful quantum randomness](https://www.wearedevelopers.com/videos/100257-colorful-quantum-randomness) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
