Physical Design Engineer Intern Jobs in Puerto Rico

This position will offer you the ability to apply and expand your knowledge of underground transmission line engineering, including routing, duct bank configurations, manhole placement and electrical principles to:

• Design underground transmission lines for voltages up to 500kV.
• Responsible for cost analyses, development of design criteria, siting and routing challenges, and placement of manholes for underground transmission lines.
• Responsible for physical design including duct bank layouts, development of trenchless designs, cable pulling calculations, development of drawing packages.
• Responsible for cable selection studies, determining bonding scheme, performing ampacity calculations.
• Develop riser structure configuration and structural loading.
• Develop specifications including cable procurement, duct bank installation, trenchless installation and general construction specifications.
• Work and coordinate with vendors and clients to specify transmission line components.
• Direct a small project team of other engineers, designers and drafters.

This role offers a hybrid work arrangement. You'll spend three days a week in the office, giving you the flexibility to work remotely for two days.

Dependent upon your location, this opportunity offers a generous relocation package.

We do not sponsor employees for work authorization in the U.S. for this position.

Essential skills and experience:

• This position requires a BS degree from an ABET-accredited engineering program.
• Proficiency with CYMCAP modeling
• Proficiency with cable tensioning calculations and/or software
• 7 or more years of experience as a member of a project team in observing project schedules and budget constraints on diverse underground transmission projects
• Design experience incorporating code requirements, EPRI recommendations, client requirements
• Experience in cost estimate development and schedule creation and coordination
• Experience with XLPE cable design
• Experience in the preparation of specifications for installation and procurement of underground transmission line materials and components
• Knowledge to verify/review right of way requirements, bonding schemes, underground transmission line plan and profile drawings and other construction documents
• Knowledge of design techniques, tools, and principles involved in the production of technical plans, drawings, and models
• Experience in writing and providing support documentation for engineering calculations
• Familiarity with design codes and standards such as NESC, EPRI Green Book, IEC, CSA, IEEE, ANSI, IBC, ASCE 7, AISC, and ACI 318
• Proficiency with MS Office applications
• Excellent written, verbal and interpersonal communication skills
• Attention to detail
• Must be bilingual in Spanish and English (read, speak, and write).

Valued but not required skills and experience:

• Have a current PE license or the ability to acquire one within one year
• Experience with High Pressure Gas Filled or High-Pressured Fluid Filled pipe type cable systems and associated equipment
• Experience with underground distribution or low voltage cable systems

In this role, we expect people to be willing or able to lead others who use modern tools:

• You are expected to lead others in taking engineering problems from issue to solution by setting expectations for using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
• Leaders in these roles often direct automation and process-improvement work, for example, how teams automate calculations, summarize technical documents, or generate design documentation and guiding when and how AI or agentic AI tools are used while ensuring results are checked.
• Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required.
• We also value additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.
