Top Tech Jobs & Startup Jobs in Austin, TX

Own mechanical design for critical modular nuclear reactor systems from concept through production. Lead structural, thermal, fatigue, and seismic analyses; develop 3D CAD models, drawings, GD&T, specifications, BOMs, and interface documents. Drive design reviews, technical decisions, DFM/DFA, prototype testing, and production transitions. Collaborate with manufacturing teams, mentor junior engineers, and support rigorous design documentation in a regulated, factory-based environment.

Hands-on Supply Chain Manager to build and scale end-to-end supply chain for factory-fabricated microreactors. Own supplier relationships, purchasing execution, inventory and demand planning, MRP contributions, and cross-functional alignment with Engineering, Quality, Manufacturing, and Finance to ensure reliable material availability and scalable processes.

Leads receiving, inventory control, material storage and routing, production kitting, point-of-use support, and inbound and outbound logistics across Austin and Idaho Falls. Builds scalable processes, controls, metrics, and teams while ensuring material traceability, inventory accuracy, quality compliance, and operational readiness. Partners with Purchasing, Quality, Engineering, Manufacturing, Planning, Finance, carriers, and suppliers to resolve issues and improve material flow.

Manage engineering and technical documents through controlled workflows, including numbering, formatting, metadata, approvals, revisions, archival, and distribution. Support document procedures, configuration control, audits, inspections, and cross-functional documentation needs for engineering, quality, regulatory, and project teams. The role requires strong technical writing, organization, and experience with document control or configuration management in a regulated or engineering-focused environment.

Supports bottom-up cost models, should-cost estimates, program budgets, budget-versus-actual tracking, variance analysis, procurement quote comparisons, make-or-buy decisions, and sensitivity analyses for complex hardware assemblies. The role collaborates with Finance, Engineering, Manufacturing, Supply Chain, Quality, and Project Management while developing practical cost-engineering skills in a nuclear hardware environment.

Supports video production for social media, web, and recruiting by editing short- and long-form content, creating platform-specific cuts, assisting with camera, lighting, and audio setup, capturing and organizing B-roll, maintaining footage libraries, and taking projects from concept through final delivery. The intern collaborates with stakeholders, incorporates feedback, and meets publishing deadlines.

Support the marketing and communications team by creating and scheduling social media content, designing graphics, developing messaging, writing and proofreading copy, maintaining content libraries and calendars, conducting industry research, reporting on campaigns, and analyzing content performance. The internship is onsite in Austin, Texas, and focuses on public-facing communications for an advanced nuclear energy company.

Create and maintain precise 2D and 3D mechanical CAD drawings using Siemens NX, applying ASME Y14.5 GD&T standards. Collaborate with engineers to convert concepts into manufacturable, testable designs, maintain drawing packages across iterations, support configuration management, and participate in design reviews and quality improvements for advanced nuclear reactor systems.

Design, build, instrument, and execute physical tests for mechanical, thermal, fluid, pressure, and chemical systems. Own test development from concept through fixture design, procurement, assembly, shakedown, troubleshooting, data capture, and analysis. Create procedures and safety controls, interpret experimental results, and translate findings into design improvements. Collaborate with engineering, manufacturing, procurement, fabrication, EHS, and operations to develop disciplined prototype and validation capabilities for advanced nuclear reactor systems.
