Principal Airframe Design Engineer

We need to output HTML fragment with sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections that have real specific content. We must not repeat job title. Must not include Job ID etc. Must remove boilerplate, navigation, legal, EEO, etc. Must preserve all substantive info. We need to parse the posting. Let's extract sections: - "Who We Are" description: mission etc. Could be considered "About the role"? Actually "About The Role" heading present. So we need an

About the role

with content from that section. - Then "What You’ll Do" is responsibilities. - Then "Required Qualifications" and "Preferred Qualifications" maybe combine into Requirements and Qualifications? The instruction: Use headings for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Skills). So we need to map content. We have "Required Qualifications" and "Preferred Qualifications". Could treat "Requirements" as required qualifications, and "Qualifications" as preferred? Or maybe "Skills" separate. But we have many skill-like items in responsibilities. We need to decide: Provide sections that have real content. We have: - About the role: paragraph(s) under "About The Role". That includes description of role responsibilities overview. - Responsibilities: bullet list under "What You’ll Do". That's a list of duties. - Requirements: maybe "Required Qualifications" bullet list. - Qualifications: maybe "Preferred Qualifications" bullet list. - Skills: maybe we could extract skill items from responsibilities or qualifications? But we could also omit Skills if not distinct. - Benefits: there is a "Benefits & Perks" section with list. - Pay: "Compensation US Salary Range: $153,000 - $206,000 USD". Also note about range etc. That's specific content. - Schedule: maybe work environment includes location, on-site, travel up to 10%, flexible hours, lift 30 lbs, etc. That could be schedule? Actually schedule heading maybe for work hours, shift, remote etc. We have "Work Environment" includes location, on-site, travel, lift, flexible hours. Could treat as Schedule? Or maybe we could create a "Work Environment" but not in allowed headings. The instruction says use those headings only; we can omit if not matching. But we could put schedule info under Schedule heading if we have info like "Willingness to travel up to 10% domestically for testing and demonstrations Ability to work flexible hours and travel to various testing locations as needed". That's schedule-ish. Thus we will include Schedule section with that info. We must not include boilerplate like Export Control Compliance, Equal Opportunity Statement, etc. Also remove duplicated lines. We must preserve all substantive information; do not invent or summarize away detail. So we need to keep the details from each section. We need to format using

for headings,

• for lists,

  for prose. We must not include markdown fences. Let's extract content precisely. First, "About The Role" paragraph: "Firestorm is seeking a highly skilled Principal Airframe Design Engineer to join our innovative engineering team in developing next-generation UAV systems. As an Principal Airframe Design Engineer at Firestorm, you will be responsible for the design and build efforts of critical flight structures and mechanisms within our product line.

We'll put as
  . Next, Skills: Could we extract skill items from responsibilities? But we already have many skill-like items in qualifications. The instruction says we can include Skills section only if posting has real specific content for it. The posting does not have a separate "Skills" heading; but we could still create a Skills section if we have skill-specific content not covered elsewhere. However we risk duplicating. Better to omit Skills section if not explicitly present. The instruction: "include a section ONLY when the posting has real, specific content for it — never emit a heading followed by filler/placeholder text". Since there is no explicit Skills section, we should not create one. Next, Benefits: "Benefits & Perks" section. We need to extract the list: - We offer comprehensive medical, dental, and visions plans - 401(k) Retirement Savings Plan to invest in your long-term retirement goals - Equity grants for new hires - Unlimited PTO - Extremely generous company holiday calendar, including a holiday hiatus in November, & December. - Generous Parental Leave - Lifestyle Spending Account - FSA DCFSA HSA Hospital Indemnity insurance - Critical Illness insurance - Accident insurance - Basic Life/AD&D, short-term and long-term disability insurance, 100% covered by Firestorm. Plus, the option to purchase additional life insurance for you and your family. - Mental Health Resources: We provide free mental health resources 24/7 including therapy and more. - Additional work-life services, such as free legal and financial support, are available to you as well. We need to preserve all substantive info. Some items are a bit run-on; we can keep as separate list items. We'll create
  • for each. Next, Pay: "Compensation US Salary Range: $153,000 - $206,000 USD". Also note: "The posted salary range reflects an estimate based on a variety of compensation factors, including but not limited to relevant experience, education, certifications, specialized skills, geographic location, and business needs. Actual compensation may vary, and this range is subject to change as our compensation structure or market conditions evolve." We'll put that in

    . Next, Schedule: Work environment info. From "Work Environment": "Based at our Headquarters in San Diego, CAThis role requires an on-site presenceMust be able to lift up to 30 lbs. and wear appropriate PPE [as required]Willingness to travel up to 10% domestically for testing and demonstrationsAbility to work flexible hours and travel to various testing locations as needed" We need to separate sentences. Let's rewrite as prose: "Based at our Headquarters in San Diego, CA. This role requires an on-site presence. Must be able to lift up to 30 lbs. and wear appropriate PPE as required. Willingness to travel up to 10% domestically for testing and demonstrations. Ability to work flexible hours and travel
