Senior Chemical Process Engineer

We need to output only HTML fragment, no html/body tags, no markdown fences. Use

for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We need to include sections only if posting has real specific content. Let's parse the posting. We have: - Who We Are: description of company. Could be "About the role"? Actually "About the role" is typical heading for role description. The posting includes "Position Overview". That could be "About the role". We'll treat that as About the role. - Key Responsibilities: list bullet points. - Required Qualifications: list bullet points. - Desired Qualifications: list bullet points. - Office location: "Our office headquarters is located in Playa Vista, CA. This position requires in-office presence." Could be under "Schedule"? Not exactly schedule. Could be "Location" but not in allowed headings. We could put under "Benefits"? Not appropriate. Could be omitted? The instruction: include a section ONLY when posting has real, specific content for it. We have Pay: salary range given: $137,000-$193,000. So we can create Pay section. - Benefits: not mentioned explicitly. No benefits listed. So we should not create Benefits section. - Schedule: not mentioned besides in-office presence. Could be considered schedule? Not explicit. Probably skip. - Skills: maybe we can combine desired qualifications as Skills? But we have separate headings: Skills, Qualifications. The posting has Required Qualifications and Desired Qualifications. Could map Required Qualifications to "Requirements" (or Qualifications). Desired Qualifications to "Skills". The instruction: Use headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. So we need to decide mapping. We have: - About the role: Position Overview + Who We Are? Probably combine. - Responsibilities: Key Responsibilities. - Requirements: Required Qualifications. - Qualifications: maybe also Required? But we have both Requirements and Qualifications headings. Could treat Requirements as "Required Qualifications" and Qualifications as "Desired Qualifications"? Or maybe Requirements = Required Qualifications, Qualifications = Desired Qualifications. Skills could be something else like technical skills? But we don't have separate skills list. Could omit Skills if no specific content. But we have Desired Qualifications which could be considered Skills. However we already have Qualifications heading; maybe we should use Qualifications for both required and desired? But we need to avoid empty sections. Let's think: The instruction: "Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It gives examples, not mandatory to use all. We should include a section only when posting has real, specific content for it. So we need to decide which headings have content. We have content for: - About the role: Yes (Position Overview + Who We Are). Could be combined. - Responsibilities: Yes (Key Responsibilities). - Requirements: Yes (Required Qualifications). - Qualifications: Could be Desired Qualifications (maybe treat as Qualifications). Or we could treat Desired Qualifications as Skills. But we have both headings; we could include both Qualifications and Skills if we have content for each. Desired Qualifications could go under Qualifications, and maybe we could put some specific skills under Skills (like "Experience with sol-gel processing at production scale", etc). But those are also desired qualifications. Might be redundant. Better: Use Requirements for Required Qualifications, Qualifications for Desired Qualifications, and omit Skills (since no separate skills list). Or we could put some of the desired qualifications under Skills and keep Qualifications for something else (maybe education?). But we already have education in Required Qualifications. Let's decide: - About the role: combine Who We Are and Position Overview. - Responsibilities: Key Responsibilities. - Requirements: Required Qualifications. - Qualifications: Desired Qualifications. - Pay: Salary range. - Schedule: In-office presence (maybe we can treat as Schedule? Not exactly schedule but could be work schedule: in-office presence). The posting says "This position requires in-office presence." That's about location/work arrangement, not schedule (hours). Could be considered Schedule? Might be a stretch. Safer to omit Schedule if not explicit. - Benefits: none. - Skills: none separate. Thus output sections: About the role, Responsibilities, Requirements, Qualifications, Pay. Now we need to format. Use

for each heading. Under each heading, we need to put content: either

for prose, or

• for lists. We must preserve ALL substantive information; do not invent or summarize away detail. So we need to include all details from each section. Let's extract details. About the role: Combine Who We Are and Position Overview. Who We Are paragraph: "Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions. The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach. Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry." Position Overview paragraph: "The performance of Inversion’s maneuvering reentry vehicles requires that we develop our own TPS materials — and making them at scale requires production-grade wet chemistry. As the Senior Chemical Process Engineer, you will stand up the sol-gel infusion and resin injection manufacturing processes at the heart of our thermal protection system production, carrying them from lab-scale demonstration to reliable, documented production." We should keep both paragraphs as prose under About the role. Now Responsibilities: Key Responsibilities list bullet points: - Develop and stand up sol-gel infusion and resin injection manufacturing processes, from process definition through commissioning of production equipment. - Specify, design, and procure process equipment, including infusion and injection systems, vacuum and pressure vessels, resin delivery hardware, and drying and cure equipment. - Characterize and control the process variables that drive product quality — sol rheology and gelation kinetics, resin viscosity and pot life, degassing, infiltration uniformity, and cure behavior. - Scale processes from coupon-level development articles to full-scale production hardware. - Establish process documentation, travelers, and statistical process control to make processes repeatable across operators and lots. - Establish safe handling practices for production-scale wet chemistry, including solvents and reactive resin systems. - Work closely with materials scientists, manufacturing engineers, and outside vendors to bring new process capabilities in-house at Inversion. We need to preserve all details exactly as given. Use
  • . Now Requirements: Required Qualifications list bullet points: - Bachelor's degree in Chemical Engineering, Materials Science, Mechanical Engineering, or equivalent experience in a related field - Typically, 5+ years of experience in process development and scale-up of wet-chemistry or polymer manufacturing processes - Experience with infusion, infiltration, or impregnation-based manufacturing processes — such as sol-gel infusion, resin transfer molding (RTM/VARTM), matrix infiltration, or similar - Strong fundamentals in polymer and colloid processing, including rheology, gelation and cure kinetics, and mass transfer during infiltration - Experience carrying a process from laboratory demonstration to production, including equipment specification and commissioning - Experience with process safety practices for hazardous chemistry at production scale (e.g., PHA/HAZOP) - Proven ability to work effectively in a fast-paced environment, including prototyping and rapid iteration of new products - Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance. We need to keep each bullet exactly. Now Qualifications: Desired Qualifications list bullet points: - Master's or PhD in Chemical Engineering, Materials Science, or a related field - Experience with sol-gel processing at production scale — such as aerogel blanket manufacturing, oxide CMC densification, polymer infiltration and pyrolysis (PIP), or catalyst washcoating - Experience with solvent exchange and supercritical or ambient-pressure drying processes - Experience processing phenolic or other ablative resin systems - Familiarity with process automation and controls (PLC/SCADA) for chemical process equipment - Prior experience working in startups and/or small independent teams Now Pay: The posting includes salary range and explanation. Paragraph: "The California annual base salary for this role is currently $137,000-$193,000 Pay Grades are determined by role, level, location, and alignment with market data. Individual pay will be determined on a case-by-case basis and may vary based on the following considerations: interviews and an assessment of several factors that are unique to each candidate, job-related skills, relevant education and experience, certifications, abilities of the candidate and internal equity." We need to preserve all substantive information. So we should include that paragraph as prose under Pay. We should not include the ITAR Compliance, EEO, etc. Remove boilerplate. Now ensure we don't repeat job title as heading. The job title is "Senior Chemical Process Engineer". Not used as heading. Now output HTML fragment. Structure:

    Make sure no extra whitespace? It's fine. Now check for any omitted content: The "Who We Are" includes "Headquartered in Los Angeles". Also later they mention office headquarters in Playa Vista, CA. That location info is not included in About the role (we only used Who Are which said Headquartered in Los Angeles). The posting also says "Our office headquarters is located in Playa Vista, CA. This position requires in-office presence." This is location info not captured. Should we include it somewhere? Could be under About the role as additional prose. Since we have About the role section, we can add that sentence after the Who Are paragraph. It's substantive. So we should include it. Thus About the role prose: combine Who Are, Position Overview, and office location sentence. Let's craft: "Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space.
