Mechanical Engineering Intern (Energy/Power) - Summer 2027

At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.

Your impact

We’re seeking Mechanical Engineering Interns to join our growing Energy & Power team at different office locations across the United States who can apply knowledge gained in school to solving today’s engineering challenges.

At Jacobs, the Energy & Power team is building on a strong track record in energy markets to drive sustainable progress and set new industry standards in a rapidly changing world. The Energy & Power team’s project portfolio includes work for utilities, universities, government entities, and advanced manufacturing. We help our clients reach ambitious decarbonization goals

As a Mechanical Engineering Intern, you will integrate into a team of experienced engineers. You will report to a senior engineer while working closely with an engineering team on different projects. Your day-to-day responsibilities will include performing engineering design. Project work performed by previous Energy & Power interns include:

• Thermal fluid system design using fluid dynamics, mechanics of materials, and multi-domain energy system analysis
• District energy system design using building energy modeling and energy system efficiency optimization programming
• Deliverable development tasks like Computer Aided Drafting and Building Information Modeling, parts and equipment scheduling, Process Flow Diagramming, and report development

Mechancial Engineering Interns typically perform engineering tasks such as:

• Piping, ducting, and equipment sizing
• Stress analysis
• Life cycle cost analysis

Mechanical Engineering Interns will be provided opportunities to either experience a broader array of engineering projects to explore different interests or to focus work on a specific project to develop mastery of skills and subject matter expertise. The team will meet with the intern regularly to discuss early career goals and development and ensure a gratifying internship experience. Interns are provided with experiences intended to maximize your summer internship experience including training, site visits, and social engagements with other interns and new engineers.

Here's what you'll need

• Currently enrolled in a degree-seeking program for Mechanical Engineering or related engineering discipline from an ABET- accredited program

Ideally, you’ll also have:

Completed lower-classman level coursework such as thermodynamics, mechanics of materials, and engineering computation and numerical methods; more advanced coursework is a plus

An interest in learning and gaining experience with engineering tools such as hydraulic modeling, heat transfer, computer aided drafting, stress modeling, or energy modelling software

Familiarity or experience with: 3D modeling software such as Revit, AutoCAD, CADWorx and NavisWorks

• hydraulic modeling software such as Pipe-Flo or AFT Fathom
• systems modeling software such as Thermoflow or Aspen/Hysys
• Authorization to work in the United States without the need for visa sponsorship now or in the future.

Our health and welfare benefits are designed to invest in you, and in the things you care about. Your health. Your well-being. Your security. Your future. Employees have access to a 401(k) plan, as well as legally mandated benefits.
