Top Tech Jobs & Startup Jobs in Los Angeles, CA

Design, source, build, and validate custom tooling, jigs, and fixtures to enable safe, repeatable, and scalable manufacturing. Collaborate with machinists and engineers, troubleshoot production tooling, and ensure tooling meets safety, ergonomic, and operational requirements.

Lead cross-functional programs supporting permitting, government and community engagement, and operational priorities for a new site. Coordinate stakeholders, manage schedules, prepare executive briefings, track regulatory and permitting activities, mitigate risks, establish scalable program processes, and represent the company at public meetings and events.

Design, build, and maintain custom test solutions (hardware and software) for in-house electronics and electro-mechanical hardware. Select or design PCBAs and COTS hardware, write Python automation, run test campaigns, root-cause anomalies, and collaborate with design and manufacturing to improve reliability and safety.

Embed with engineering teams to accelerate workflows using AI: build LLM/agent-based tools, automate simulation pipelines, integrate with internal tools, and prototype solutions to speed safety, neutronics, and design analyses.

Support the Nuclear Material Control & Accountability program by performing statistical calculations, tracking and verifying measurement data, estimating uncertainties, designing MC&A reporting forms/spreadsheets, assisting physical inventories and reconciliations, and preparing compliance reports while working with engineers and safeguards staff.

Design, build, and maintain custom test solutions and data-acquisition systems to validate mechanical and electrical hardware. Lead design reviews, execute hardware test plans and qualification campaigns, analyze failures, implement test automation, and collaborate with design and manufacturing engineers to improve reliability.

Own end-to-end procurement and supply chain for mechanical, electrical, and specialty hardware. Source and qualify suppliers, run RFQs, negotiate contracts, manage inventory/lead times, maintain forecasts and vendor performance, implement scalable material-planning processes, and collaborate with engineering, manufacturing, and finance to ensure material readiness and cost optimization.

Design, build, and qualify fixtures, jigs, and workholding for CNC mills and lathes. Partner with machinists and CNC programmers to validate setups, source components, perform first-article inspection, maintain a tooling library, drive continuous improvement, and support facility tooling layout for production ramp-up.

Own dynamics, loads, and vibration analysis for hardware driving requirements, testing, data analysis, and model correlation. Define vibe/shock requirements, execute test programs, perform root-cause analysis, optimize designs for cost and manufacturability, and collaborate with cross-functional engineering teams to ensure integrated system performance.

Execute end-to-end procurement for EPC projects (including NRC-regulated), including sourcing, RFQs, bid evaluation, negotiation, purchase orders, supplier management, compliance with technical/regulatory requirements, performance monitoring, documentation, reporting, and continuous improvement.
