Senior Air Quality Specialist, Technical Leader

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. Remove boilerplate. Must preserve all substantive info. We need to parse the job posting. Key sections: - Description: includes "DOES THIS DESCRIBE YOU?" paragraph, then "Ascent is seeking a full-time Senior Air Quality Specialist, Technical Leader to join our AGENTs team..." then "In a typical week in this role, you might:" list of duties. - Requirements: list of education, experience, skills. - Work environment: typical office environment, hybrid, physical demands, travel, work authorization. - Benefits: mention competitive salaries, comprehensive medical benefits, perks, link to benefits listing. - Pay: Salary Description $120,000-$150,000. - Schedule: Not explicitly given; maybe full-time, hybrid. There's "Work environmentTypical office environmentHybrid". Could infer schedule: full-time, hybrid. But we should only include Schedule if posting actually states it. It says "Job TypeFull-time" at top, and "Hybrid". So we have schedule info: full-time, hybrid. Could include Schedule section with that. But we must not create sections with filler like "not specified". So we can include Schedule if we have concrete info: Full-time, hybrid. Now we need to decide headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We have content for About the role (the introductory paragraph about you and the role). Responsibilities (the list of duties). Requirements (education, experience). Qualifications maybe overlapping with Requirements; but we can combine? The instruction: prefer few substantive sections over many thin ones. We could merge Qualifications into Requirements or Skills. But we need to follow headings list; we can omit sections lacking content. So we can include About the role, Responsibilities, Requirements, Benefits, Pay, Schedule. Possibly Skills could be extracted from requirements (strong analytical, computer, spreadsheet, writing skills, proficiency in emissions modeling software). Could make Skills section. Qualifications maybe similar to Requirements; we could omit Qualifications if we already have Requirements covering qualifications. But we need to decide. Let's extract: About the role: The opening paragraph: "DOES THIS DESCRIBE YOU? You’re a technically strong, solutions-oriented air quality expert..." plus "Ascent is seeking a full-time Senior Air Quality Specialist, Technical Leader to join our AGENTs (Air Quality/Greenhouse Gas/Energy/Noise/Transportation) team in any of our offices: Berkeley, Irvine/Orange County, Lake Tahoe, Sacramento, or San Diego." That's about the role. Responsibilities: The bullet list after "In a typical week in this role, you might:" includes: - Independently conduct emissions modeling, including Health Risk Assessments using CalEEMod, Excel, AERMOD, EMFAC, HARP, and OFFROAD. - Conduct, review, and provide QA/QC feedback on emissions modeling from software, including but not limited to Calero, Excel, AERMOD, EMFAC, HARP, and OFFROAD. - Lead and direct marketing and business development pursuits, including developing capture strategies. - Lead the preparation of proposals for midsized projects and assist with proposals for larger projects, providing technical input, contributing to proposal writing through scope and cost development, identifying opportunities, and engaging with proposal/interview teams. - Collaborate with the AGENTs team to provide mentorship, build technical capabilities and services, ensure high-quality deliverables, and develop internal training materials and modeling protocols. - Work collaboratively with Ascent’s Environmental Practice Group to ensure timely delivery of technical work meeting Ascent’s quality standards. Also note the disclaimer about duties may change; we can ignore as boilerplate. Requirements: list: - Civil or environmental engineering, math, environmental science, atmospheric science, meteorology, geography, natural resources management, planning, or a related field. - A minimum of 8 years of direct professional experience conducting CEQA/NEPA air quality and GHG assessments. - Strong analytical, computer, spreadsheet, and writing skills are a must, and proficiency in emissions modeling software for development projects in California. - Successful candidates will have demonstrated experience running air quality emission models (EMFAC, CalEEMod, OFFROAD, MOVES) and dispersion models (CALINE-4, AERMOD, HARP) to evaluate project-related construction and operational emission and health impacts. - Candidate will have experience conducting emissions modeling QA/QC reviews, paying close attention to modeling methodologies and model accuracy. - Familiarity with state and federal air quality and climate change environmental policy and regulation, including CEQA, NEPA, and Clean Air Act, preferred. - Thorough understanding of the principles and practices, including meteorology, chemistry, and factors affecting air pollution distribution and effects. - Understanding of US EPA, California Air Resources Board, and local Air Quality Management District or Air Pollution Control District air quality regulatory programs and their relationship to the Federal and State Clean Air Acts. Work environment: typical office environment, hybrid, physical demands (prolonged sitting, lift 15 pounds), travel limited, work authorization: Not eligible for sponsorship, Additional eligibility: N/A (we can drop N/A as filler). Might include as part of Requirements? But we could incorporate into About the role? Probably better to include in a separate section like Work environment, but not in headings list. Since headings list does not include Work environment, we could fold into About the role or Responsibilities? Probably better to include in About the role? But we have limited headings; we could incorporate into About the role as extra paragraph. However the instruction: "Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It suggests we can use those headings but not required to use all. We can also add other headings? It says "use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." That implies those are examples; we could use other headings if needed, but better to stick to those. We could incorporate work environment details into About the role or Responsibilities. Benefits: "At Ascent, we believe in fostering a nurturing environment that prioritizes our people. We are committed to holistic investments in our team, offering not only competitive salaries and comprehensive medical benefits but also a range of perks designed to enhance emotional, financial, and physical wellness. A comprehensive listing of benefits offered can be found here. As a people-first organization, we value and will strive to ascend by welcoming and uplifting all voices, ideas, achievements, and contributions, including those from marginalized communities and identities. We believe that recognizing and embracing our differences makes us a stronger organization. We commit to proactively nurturing environments of mutual support, respect, and caring for all through our words and actions. Interested in learning more about Ascent's culture? Reach out to our People Resources team at PeopleResources@ascent.inc. We look forward to hearing from you!" We should keep the substantive benefits: competitive salaries, comprehensive medical benefits, range of perks for wellness, people-first culture, etc. The link "can be found here" we can keep as is. Pay: Salary Description $120,000-$150,000. Schedule: Job Type Full-time, Hybrid. So we can say: Full-time, hybrid schedule. Now we need to output HTML fragment with

headings and

• for lists,

  for prose. We must not include markdown fences. Let's craft:
