Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Test Infrastructure Engineer - **Company:** Avalanche Energy - **Location:** Tukwila, WA, United States - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** 3d Models, Computer-Aided Design, Control Panels, SolidWorks (CAD) - **Published:** October 23, 2026 - **Apply:** https://www.thejobnetwork.com/job/35688848-579a-4c00-8861-b272da32d40d/test-infrastructure-engineer ## About the Role * Bachelor's degree in mechanical engineering, aerospace engineering, or a related field, or equivalent practical experience \n * Strong mechanical design skills, including 3D CAD, detailed drawings, tolerancing, material selection, and design for fabrication and assembly \n * Demonstrated hands-on experience building, installing, commissioning, maintaining, or repairing equipment you designed \n * Experience designing fixtures, tooling, test stands, prototype equipment, or industrial machinery \n * Working knowledge of electrical systems, instrumentation, sensors, controls, and basic electrical troubleshooting \n * Experience integrating fluid, pneumatic, vacuum, thermal, or other facility-supported systems \n * Ability to safely use common hand tools, power tools, measurement equipment, and shop equipment \n * Ability to take ambiguous needs from concept through working hardware with limited oversight \n * Strong ownership, practical judgment, communication skills, and attention to detail in a fast-moving R&D environment \n * Three or more years of experience in tooling, test, manufacturing, or R&D engineering \n, * Experience with SolidWorks or a comparable mechanical CAD and drawing system \n * Experience designing welded structures, machined parts, sheet-metal assemblies, guards, platforms, or equipment frames \n * Experience designing or building radiation shielding systems \n * Familiarity with vacuum or ultra-high-vacuum systems and vacuum-compatible design practices \n * Experience with chillers, pumps, heat exchangers, cryogenic systems, gas handling, or process plumbing \n * Experience working around high-voltage, high-current, stored-energy, radiation, or other hazardous-energy systems \n * Experience with PLCs, automation, machine safety, interlocks, data acquisition, or control panels \n * Experience with rigging, lifting fixtures, equipment installation, and industrial safety practices \n * Experience managing vendors, fabrication quotes, procurement, schedules, and installation work \n * Prior work in fast-paced, hardware-driven R&D, aerospace, energy, or advanced manufacturing environments ## Description You like designing practical hardware, but you do not want to stop at the drawing. You are equally comfortable in CAD, at a workbench, and in a test cell. You may be laying out a fixture in the morning, fabricating it in the afternoon, and commissioning it alongside the experiment. You think like a tooling engineer: you care about interfaces, access, tolerances, safety, serviceability, and repeatability. You take pride in building robust systems, maintaining them, and improving them when reality exposes a better solution., Travel: Occasional travel for vendor visits, equipment procurement, integration, or collaboration as needed
