We are seeking interns who are passionate about applying their technical skills, problem-solving abilities, and commitment to quality to drive the future of clean energy! Application close date: 12/31/2026"
- Then "Responsibilities will vary depending on each intern's are of expertise and interests"
- Then list: Mechanical design and hardware development, Mechanical and thermal analysis using finite element analysis, Systems engineering, Manufacturing engineering, Electrical engineering (pulsed power), Control systems engineering, Computational and software engineering (simulations), Nuclear engineering, Optical engineering, Plasma physics
- Then "Qualifications Qualified candidates must be enrolled in a Bachelor's, Master’s or PhD degree program from an accredited college or university in mechanical engineering, electrical engineer, physics, nuclear engineering, or other related engineering discipline. Application of technical skills outside of the classroom (examples include: extracurricular projects, volunteering, personal projects, laboratory research, or prior internship/work experience). Proficiency in CAD software for 3D modeling and simulation. Strong written, verbal, communication, and interpersonal skills. Passion for fusion energy! Ability to work full-time onsite through the duration of the 12 week internship program in Denver, CO. Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee of granted asylum."
- Then "$25 - $35 an hour Undergraduate intern: $25/hr Masters intern: $30/hr PhD intern: $35/hr Candidates may be considered for other positions at Xcimer Energy, and our actual base salary will be determined on an individual basis and may vary based on job-related knowledge and skills, education, and experience. The range is published in accordance with Colorado Equal Pay for Equal Work Act and California Equal Pay Act."
- Then EEO boilerplate (remove).
- Then "Benefits Benefits Employee Benefits include: Medical, dental, vision, basic and supplemental life insurance, paid parental leave (must be employed at time of birth or adoption), short and long-term disability, 401(k) with a company match of up to 6%. Paid Time Off: 15 days per year based on weekly scheduled hours, 10 paid sick leave, and 13 company-paid holidays for all regular employees (including part-time), fixed-term, and interns. Equity will be granted to eligible employees. Equity is designed to allow employees to share in company results and success. We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us."
- Then "apply for this job Xcimer Energy Home Page Jobs powered by" (remove).
We need to remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. So we remove EEO paragraph, also remove "apply for this job" lines.
We need to keep substantive info: About the role (intro), Responsibilities (list), Qualifications (list), Skills (maybe part of qualifications?), Benefits, Pay, Schedule (maybe schedule is 12-week program, full-time onsite). Also maybe "Application close date: 12/31/2026" could be schedule? Actually schedule could be duration and location. We'll include a Schedule section with "12-week full-time onsite internship in Denver, CO. Application close date: 12/31/2026." That is specific.
Pay: we have hourly rates.
Benefits: we have details.
We need to avoid placeholder like "commensurate with experience" etc. We have actual numbers.
We must not repeat job title as heading. So we will not include a heading for the job title.
We need to use for section headings. Use - for any list of duties/requirements/benefits. Use
for prose.
We need to decide sections: About the role (intro paragraph), Responsibilities (list), Qualifications (list), Skills (maybe combine with qualifications? but we have separate skill items: proficiency in CAD, strong communication, etc. Could be Skills section). Benefits (list), Pay (maybe paragraph with rates), Schedule (paragraph with duration and close date). Ensure we only include sections with real content.
Let's extract:
About the role: The introductory paragraph(s) before responsibilities. Could combine first few sentences up to "Application close date: 12/31/2026"? Actually that is schedule. Better to separate.
We'll create About the role: description of company, mission, internship program, disciplines, location, mentor, etc. Up to "We are seeking interns who are passionate about applying their technical skills, problem-solving abilities, and commitment to quality to drive the future of clean energy!" That seems like role description.
Then Responsibilities: list of tasks.
Then Qualifications: enrollment, etc.
Then Skills: proficiency in CAD, strong written/verbal communication, interpersonal skills, passion for fusion energy, ability to work full-time onsite, citizenship requirement? Actually citizenship is qualification. Might be part of qualifications. But we can keep qualifications include enrollment, technical skills outside classroom, CAD proficiency, communication skills, passion, full-time onsite, citizenship. Skills could be just CAD proficiency and communication. But we can combine.
Better to follow typical sections: About the role, Responsibilities, Qualifications, Benefits, Pay, Schedule. Skills could be part of Qualifications.
But the instruction says use headings for those categories if content exists. We can include Skills if we have distinct content.
Let's extract skills: "Proficiency in CAD software for 3D modeling and simulation." "Strong written, verbal, communication, and interpersonal skills." "Passion for fusion energy!" "Ability to work full-time onsite through the duration of the 12 week internship program in Denver, CO." That's more like requirement.
Thus we could have Qualifications (education, experience) and Skills (CAD, communication, passion, full-time). But we can keep Qualifications include education, experience, CAD, communication, passion, full-time, citizenship. That's fine.
Thus we may not need separate Skills section.
We'll include: About the role, Responsibilities, Qualifications, Benefits, Pay, Schedule.
Now we need to format.
About the role: prose
. Combine sentences.
Responsibilities:
- each item.
Qualifications: maybe
- each bullet.
Benefits:
- each bullet.
Pay: maybe
with rates.
Schedule:
with duration and close date.
We must not include duplicated lines. Ensure we don't include "apply for this job" etc.
Let's craft.
