  • Manufacturing Engineering: These engineers bridge the gap between design and production. They are responsible for developing the processes, tooling, and workflows used in the company’s massive production facilities.

Manufacturing and Operations

For those with a background in skilled trades and industrial production, Solar Turbines provides a stable and high-tech manufacturing environment. Unlike many traditional "shop" jobs, the work here involves extremely tight tolerances—often measured in microns—due to the high speeds at which turbine components rotate.

  • CNC Machinists and Operators: Using advanced multi-axis machines, these professionals carve complex components like turbine blades and impellers out of specialized alloys. Knowledge of G-code, Kuraki CNC machines, and precision measuring equipment is often required.
  • Welders and Assemblers: Specialized welding techniques, including TIG and arc welding, are critical for structural integrity. Assemblers handle the final buildup of the engines, ensuring that thousands of individual parts come together in a perfectly balanced system.
  • Quality Assurance and Inspection: Given the critical nature of the equipment, quality inspectors use non-destructive testing (NDT), coordinate measuring machines (CMM), and other forensic tools to ensure every part meets Caterpillar’s rigorous standards.

Field Service and Global Support

One of the most unique career paths at Solar Turbines is the Field Service Representative (FSR) role. These individuals are the company’s "boots on the ground," traveling to customer sites in over 100 countries.

A career in field service is demanding but rewarding for those who enjoy travel and hands-on troubleshooting. An FSR might spend one month on an offshore oil platform in the Gulf of Mexico and the next at a pipeline station in the Middle East. The role requires a high degree of autonomy, technical problem-solving skills, and the ability to represent the brand in high-pressure situations where equipment downtime can cost customers millions of dollars.

Business and Professional Roles

Beyond the engine itself, Solar Turbines requires a robust corporate infrastructure. This includes:

  • Supply Chain and Procurement: Managing a global network of suppliers for raw materials and specialized components.
  • Finance and Accounting: Handling the complex economics of multi-million dollar equipment contracts and long-term service agreements.
  • Human Resources and EHS: Solar Turbines places an extraordinary emphasis on Environmental, Health, and Safety (EHS). Safety isn't just a policy; it's a core cultural pillar that influences every decision on the factory floor and in the field.

Entry-Level Programs and Professional Development

Solar Turbines is known for its "promote from within" philosophy and its commitment to developing the next generation of industrial experts.

Internship and Co-op Programs

The company offers structured internships typically aimed at university students in engineering, IT, finance, and supply chain. These are not "coffee-fetching" roles; interns at Solar are embedded into active project teams and given real-world responsibilities. Recruitment for these roles often starts in the fall for the following year's summer cycle.

Engineering Rotational Program

For recent graduates, the 24-month Engineering Rotational Program is highly coveted. Participants move through different departments—such as design, test, manufacturing, and field service—every six months. This provides a holistic view of the company and helps new engineers find their niche while building a broad internal network.

Manufacturing Apprenticeships

In regions like San Diego and Texas, Solar Turbines often partners with local colleges or runs internal apprenticeship programs to train machinists and technicians. This provides a clear pathway for individuals without a four-year degree to enter a high-paying, specialized career.

Compensation and Employee Benefits

As a subsidiary of Caterpillar, Solar Turbines offers a competitive compensation package that ranks among the best in the heavy industrial sector. Based on recent internal data and public filings, the following components are typical of their offer structure:
