Staff Manufacturing Process Engineer

We need to output HTML fragment with sections: About the role? Actually the posting includes "About Mainspring" (company description) and "Job Overview", "What You'll Do", "What You'll Bring", "What Sets You Apart", plus note about flexibility, EEO, compensation/benefits, etc. We must remove boilerplate: cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, application instructions. Also we must not repeat job title as heading. Use

for section headings: e.g., About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. However we need to map content to these headings only when there is real specific content. The posting includes: About Mainspring (company description) maybe "About the role"? Actually "About Mainspring" is company overview, not role. Could be "About the role" heading? The instruction: use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we can use those headings if content matches. We have: - About Mainspring: could be "About the role"? Not exactly. But we could treat as "About the role" maybe describing role? Actually "Job Overview" is about role. So we could put "About the role" heading with content from Job Overview. - Responsibilities: from "What You'll Do" (Manufacturing Process Development, Manufacturing Optimization & Operational Excellence, Manufacturing Scale-Up). That's responsibilities. - Requirements: from "What You'll Bring" (experience, expertise). Could be Requirements. - Qualifications: maybe overlapping with Requirements; but we can combine? The instruction: prefer few substantive sections over many thin ones. So we could have sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule only if content exists. We have content for: - About the role: Job Overview paragraph. - Responsibilities: What You'll Do (multiple bullet-like paragraphs). We'll need to convert to

• for any list of duties/requirements/benefits. The content is paragraphs with sentences; we can treat each sentence as list item? Probably better to treat each bullet point as list item. The text includes headings like "Manufacturing Process Development", then sentences. We could make each major bullet as list item. - Requirements: What You'll Bring (experience, expertise). Could be list. - Qualifications: maybe "What Sets You Apart" could be Qualifications or Skills. Could treat as Skills. - Benefits: The posting mentions "Along with the base salary, Mainspring offers pre-IPO stock options + benefits." Also earlier: "This compensation and benefits information is based on Mainspring Energy's estimate..." and "Along with the base salary, Mainspring offers pre-IPO stock options + benefits." Also "The salary will be adjusted to reflect local market conditions..." So we have some benefits info: pre-IPO stock options, benefits (unspecified). Also mention of compensation: base salary, pay adjusted, etc. So we can have Benefits section with pre-IPO stock options + benefits (maybe health etc not specified). Since we cannot invent details, we only include what is stated: pre-IPO stock options + benefits. Also mention that compensation and benefits information is based on estimate and may be modified. That's maybe not specific enough. We'll include Benefits: pre-IPO stock options + benefits. - Pay: The posting mentions salary will be adjusted to reflect local market conditions, base salary, new hires tend to be paid within starting base pay range, etc. No specific numbers. Since we cannot include placeholder like "not specified" or "varies". The instruction: never emit a heading followed by filler/placeholder text (e.g., "commensurate with experience", "not specified", "N/A", "varies", "TBD"). So we cannot create Pay section if it only contains vague statements. However we have some info: "The salary will be adjusted to reflect local market conditions based on employee location as well as the experience of the employee. Along with the base salary, Mainspring offers pre-IPO stock options + benefits." That's still vague but mentions base salary and adjustment. Is that considered filler? It's not a specific number but it's substantive: says salary adjusted to local market, base salary, stock options. Might be okay. But the instruction says avoid filler like "varies". "adjusted to reflect local market conditions" is somewhat vague but still substantive. I'd include Pay section with that sentence. - Schedule: The posting says "This position is onsite at our Menlo Park HQ." That's schedule? It's location, not schedule. No schedule info like full-time, shift. So we should not create Schedule section. We must remove boilerplate: EEO statements, AI tools, etc. Also remove duplicated lines. We need to preserve all substantive information. So we need to include company description? The "About Mainspring" paragraph is substantive about company. Should we include it? Possibly under "About the role"? But that is about company not role. Could we add a section "About the company"? Not in allowed headings list. The allowed headings are limited to those examples, but we could still use other headings? The instruction: "use

  for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It implies we should use those headings for sections. It doesn't forbid other headings, but suggests using those. Safer to stick to those. So we need to map company description maybe under "About the role"? Not ideal but we could include a brief sentence about company within About the role. However the instruction: "Do NOT repeat the job title as a heading (the page already shows it) and do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short

  or drop it." So we can have a

  for company description maybe not under a heading? But we need to output only HTML fragment; we can include

  directly without heading? The instruction about headings is for sections; we can have paragraphs outside sections? Probably we should structure with headings for each section; any intro text could be a

  before first heading. But they said "use

  for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." So we can have

  About the role

  then content. The company description could be part of About the role? Might be okay. Let's extract substantive content: About Mainspring paragraph: "About Mainspring Mainspring Energy manufactures and delivers fuel-flexible, low-emissions local power solutions that rapidly add new capacity and deliver reliable, affordable, and sustainable electric power. The company began commercial shipments of its Mainspring Linear Generators in 2020 and today has hundreds of megawatts in advanced development and field operations for leading Fortune 500 companies, data centers, and utilities. Mainspring also partners with global energy leaders including AEP, NextEra Energy Resources, Schneider Electric, and more. The core values that ground our work, guide our decisions, and connect us together: Pragmatic Optimism Excellence without Ego Proactive Collaboration" We need to keep that. Job Overview paragraph: "We are seeking a highly capable Senior/Staff Manufacturing Process Engineer with a strong foundation in manufacturing process planning, industrial engineering, and data-driven problem-solving to bridge the gap between product development and scalable manufacturing. In this role, you will partner closely with Mechanical, Electrical, Manufacturing, Quality, and Supply Chain teams to develop robust, scalable manufacturing processes that enable safe, repeatable, and high-volume production.

At Mainspring, we are committed to building a diverse, inclusive, flexible, and collaborative environment, so if you want to help us transition the world to clean and affordable electricity, and don’t meet all posted requirements for a particular role, we’d still love to hear from you. Mainspring can sometimes be flexible enough to shift responsibilities for the right person, or otherwise identify open or upcoming roles that may better fit your professional background. In more traditional words, Mainspring Energy, Inc is an Equal Opportunity Employer." We need to remove EEO boilerplate. The flexibility note is substantive? It's about encouraging applicants. Might be considered boilerplate? It's not EEO but it's a encouragement. Could keep as a short paragraph under maybe "About the role" or separate? The instruction: remove cookie/navigation/legal/EEO/equal-op
