Top Tech Jobs & Startup Jobs in Austin, TX

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.

Leads reliability engineering for nuclear microreactor components, subsystems, and assemblies. Develops reliability requirements, predictions, statistical models, experiments, accelerated-life tests, and verification strategies. Analyzes failure data and uncertainty, supports FMEA/FMECA and fault-tree analysis, evaluates system risks, and creates technical documentation. Collaborates with design, test, manufacturing, quality, safety, and systems teams to improve product robustness and mentors engineers.

Create video content documenting Aalo Atomics’ factory, hardware, engineering milestones, people, and events. Own productions from concept through final edit, including social videos, documentaries, launch films, recruiting content, and event coverage. Collaborate with brand and marketing teams while managing production logistics, equipment, footage libraries, and post-production workflows. The role is onsite in Austin and includes travel for shoots when needed.

Designs, builds, tests, and commissions mechanical components, mechanisms, assemblies, tooling, and reactor-support hardware. Creates CAD models, drawings, bills of materials, calculations, test procedures, and inspection plans. Integrates actuators, sensors, and instrumentation with controls systems; builds test rigs; and collaborates with machinists, welders, technicians, vendors, and senior engineers to deliver manufacturable designs. Occasional travel to test sites, vendors, and reactor installations is required.

Designs, maintains, monitors, and troubleshoots wired and wireless network infrastructure, including switches, routers, firewalls, VPNs, and related systems. Provides help-desk and endpoint management support, administers user accounts and access, maintains documentation, and assists with upgrades and infrastructure projects. Supports secure network environments interfacing with operational technology systems, including segmentation and access controls, while coordinating with internal teams, vendors, and service providers.

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.

Design, build, instrument, and operate physical test rigs for mechanical, thermal, fluid, pressure, and chemical systems. Own testing from experiment definition through procurement, assembly, shakedown, execution, data capture, troubleshooting, and analysis. Develop procedures and safety controls, interpret results, and collaborate with engineering, manufacturing, EHS, and operations to improve reactor designs and build scalable internal testing capabilities.

Own build-induced reliability risks for nuclear reactor hardware across design release, fabrication, assembly, inspection, testing, and production ramp-up. Develop quality plans, PFMEAs, work instructions, inspection strategies, and process controls; review designs for manufacturability and testability; analyze production data; investigate failures and nonconformances; and implement corrective actions. Partner with engineering, manufacturing, quality, suppliers, and production teams in a hands-on factory environment while maintaining traceable records and supporting regulated nuclear-quality requirements.

The role involves designing automated manufacturing lines, architecting control systems, PLC programming, integrating robotics, and ensuring safety standards in nuclear reactor production.

The Senior Mechanical Design Engineer leads mechanical design for nuclear reactors. Responsibilities include design ownership, engineering analyses, mentoring, and ensuring safety standards.
