Intern – Laboratory Testing Support

<ON.energy> is setting the standard for large load interconnection. ON’s patented AI UPS™ is a medium-voltage UPS that serves as a firewall, protecting the data center from the grid, and the grid from the data center. With multiple gigawatts currently under construction, we are enabling grid-safe data centers. ROLE SUMMARY
This is a six-month internship with structured assignments and increasing ownership. Strong performers may be considered for future full-time opportunities based on business need and role availability. This Intern will support test planning and reporting product and system testing at the National Laboratory of the Rockies (NLR) and <ON.energy>’s Houston laboratory. The intern will help turn engineering requirements into practical test plans, organize execution evidence, prepare clear draft reports by giving support to the laboratory engineers. This is a variable-term, remote R&D internship with optional travel.
Please Note: This is a remote position. Optional travel may include visits to NLR, Houston, or other test locations. On-site participation is subject to applicable access, training, and safety requirements.

KEY RESPONSIBILITIES

Test Plans: Help develop test plans and procedures that define the objective, required software/hardware setup and acceptance criteria. Maintain clear links between requirements, test activities, and results.
Readiness: Support test readiness and daily planning by tracking key resources, dependencies, and open items.
Execution Records: Maintain clear test logs and organize the supporting data, observations, and evidence for each test.
Coordination: Keep plans and status information current across R&D, Commissioning Engineering, and external consultants. Follow up on missing inputs and review actions with the responsible technical leads.
Issues: Document deviations and open questions for engineering review. Support test plan revisions and retest planning when needed.
Data Analysis Tool: Build a reusable tool that can ingest lab test data in different formats and produce consistent, report-ready graphs. Document the tool so future data sets can be processed efficiently and results can be reproduced.
Data Review: Check data quality, create plots, interpret and compare measured results with defined criteria under engineering direction.
Reporting: Draft test reports and concise campaign summaries covering results, issues, and next steps. Clearly distinguish measured facts from interpretation and open questions.
Document Control: Maintain organized revisions and source evidence in designated <ON.energy> repositories.
Process Improvement: Help improve reusable templates and workflows for test planning, evidence management, and reporting.

KEY REQUIREMENTS

Education: Currently pursuing or recently completed a B.S. or M.S. in electrical engineering, data science, or a related technical field.
Technical Background: Coursework or project experience related to power systems, energy storage, power electronics or laboratory testing is preferred.
Tools: Working knowledge of Excel and experience with Python, MATLAB/Simulink, or a similar data-analysis tool.
Core Skills: Strong technical writing, attention to detail, and the ability to organize engineering information across a distributed team.
Safety and Confidentiality: Follow laboratory safety, access, and confidentiality requirements. The intern will not perform energized electrical work unless a separately qualified and authorized user is present.
