Top Tech Jobs & Startup Jobs in Denver & Boulder, CO

Lead cross-functional business operations strategy and execution, translating executive decisions into resourced initiatives. Own operational process design, documentation, training, rollout, adoption reviews, headcount planning, forecasting, knowledge management, risk mitigation, and data workflow improvements. Partner with Finance, PMO, and executive stakeholders on economic modeling, program prioritization, budgeting, board materials, and investor reporting. Manage ambiguous operational projects through implementation and sustainable handoff.

Operate, troubleshoot, maintain, and improve high-voltage pulsed-power systems for an experimental laser facility. Perform electrical diagnostics, waveform analysis, component testing, corrective and preventive maintenance, commissioning, and system upgrades. Develop operating procedures, checklists, alarms, interlocks, and equipment records. Qualify as a Pulsed Power Controller, execute laser experiment procedures, support Shot Directors, and contribute to root-cause investigations and reliability improvements.

A 12-week onsite engineering internship supporting the design and development of laser-driven inertial fusion hardware and software. Responsibilities may include controls systems engineering, mechanical and thermal analysis, systems engineering, manufacturing, electrical engineering, simulations, nuclear engineering, optics, plasma physics, and pulsed power. Interns will work with expert mentors on real-world fusion power plant challenges.

Owns and integrates the Plant Control System across Xcimer’s inertial fusion plant program. Responsibilities include requirements stewardship, interface coordination, technical integration, budgets, schedules, risk mitigation, verification planning, commissioning readiness, procurement, and vendor management. The role coordinates multidisciplinary teams across plant systems, guides decisions without direct authority, and communicates program status and risks to senior stakeholders.

Optimize manufacturing of pulsed power assemblies through DFM/A, work instructions, validation procedures, hands-on assembly support, quality improvement, configuration management, and repair or rework processes. The role translates engineering designs into operational hardware, supports production teams, manages procurement and equipment, validates safety procedures, resolves nonconformances, and mentors manufacturing engineers and technicians in an onsite R&D environment.

Lead the Power Electronics and EMI/EMC sub-department within Pulsed Power Engineering. Responsibilities include managing technical development, leading personnel, creating power electronics technology roadmaps, and defining standards, specifications, requirements, and best practices for high-voltage supplies, DC-DC converters, PCB design, and EMI/EMC compliance.

Participate in a 12-week onsite engineering internship developing laser-driven inertial fusion hardware and software. Responsibilities may include optical, mechanical, electrical, systems, manufacturing, controls, computational, nuclear, or plasma engineering. Interns will apply technical skills to real-world challenges, use CAD and simulation tools, collaborate with expert mentors, and support development of commercial fusion power plant systems.

Summer interns will support mechanical design, hardware development, finite element analysis, systems engineering, manufacturing engineering, and related fusion hardware projects. The 12-week onsite program includes mentorship and hands-on work addressing real-world challenges across structures, mechanisms, thermal systems, optics, pulsed power, controls, simulations, and manufacturing.
