Mechanical Engineer - Electromechanical

We need to output HTML fragment with sections: About the role? Actually we have sections: Job Overview, Core Responsibilities, Qualifications, plus maybe Benefits (they mention pre-IPO stock options + benefits). Also Pay? They mention salary adjusted to reflect local market conditions, base salary range? Not specific numbers. They say "The salary will be adjusted to reflect local market conditions based on employee location as well as the experience of the employee." No specific range. They also say "Along with the base salary, Mainspring offers pre-IPO stock options + benefits." That's benefits info. Pay section: they didn't give explicit numbers, just mention salary adjusted, base salary range noted above? Actually they said "New hires joining the company tend to be paid within the starting base pay range noted above, with opportunities to increase pay over time..." but they didn't actually note a range earlier. So no concrete pay info. According to rules: never create Pay/Schedule/Benefits sections unless posting actually states them. Benefits: they mention pre-IPO stock options + benefits. That's a statement of benefits. So we can include Benefits section with that line. Pay: they didn't give numbers, only mention salary will be adjusted, base pay range noted above (but not given). Since no explicit numbers, we should not create Pay section. Schedule: they mention onsite at Menlo Park HQ. That's location, not schedule. No schedule info. So we omit Schedule. We need headings: About the role? The posting has "Job Overview". Could map to About the role? The instruction: use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should use those exact headings if content matches. We have Job Overview -> could be About the role. Core Responsibilities -> Responsibilities. Qualifications -> Qualifications. Also maybe Skills? Not separate. Benefits -> Benefits. We must not repeat job title as heading. Not include Job ID etc. We need to preserve all substantive information. Remove boilerplate: cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, application instructions. The posting includes EEO statement, AI tools note, etc. Those are boilerplate; we should remove them. Also remove "Before you apply, a quick note on your resume" etc? That's application instructions? It's advice for resume; maybe considered application instructions? The instruction says remove application instructions. That includes "Before you apply, a quick note on your resume..." and the bullet list. Also "Thank You!" and "Does your experience not meet all of our posted requirements?" etc. Those are encouraging to apply; likely considered application instructions. We should remove them. Also remove "Mainspring can sometimes be flexible enough..." etc. That's also encouraging. Remove EEO statement. Remove AI tools note. Remove "This compensation and benefits information is based on..." etc. That's about pay/benefits but maybe we keep benefits line? The benefits line is "Along with the base salary, Mainspring offers pre-IPO stock options + benefits." That's substantive. The surrounding sentences about compensation being based on estimate etc are boilerplate; we can discard them but keep the benefits line. We need to keep location: "This position is onsite at our Menlo Park HQ." That's substantive; maybe we can put in a

under About the role or as its own paragraph. Not a heading. We need to keep the core responsibilities list as

• . Keep qualifications as list. We need to keep the "About Mainspring" paragraph? That's company description; maybe we can include under About the role? The instruction: Use

  for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we could have About the role section containing the job overview and maybe company description. The "About Mainspring" is company overview; could be part of About the role. We'll include it. We must not invent or summarize away detail. Keep all substantive info. Let's extract substantive content: Company description: "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" Job Overview: "Mainspring is seeking Mechanical Design Engineers with a focus on designing electrical enclosures and cables while improving functionality and system-level performance. In this role, you will lead projects from setting requirements, designing, conducting cross functional reviews, coordinating testing and release to ensure that key electrical subsystems meet challenging technical requirements with a potential for direct reports. Ideal candidates will have a strong combination of technical expertise and the drive to solve complex problems in a collaborative environment." Core Responsibilities list (bullet points): - Involved in brainstorming and technical review sessions to develop innovative solutions that enhance the performance and cost-efficiency of the Linear Generator and electrical subsystems - Ownership of design, optimization, and execution of electrical hardware, balancing cost reduction, safety improvements, and system-level reliability - Collaborate with reliability and test teams to validate systems and components, ensuring fast iteration cycles and incorporating feedback to drive the next-generation deployment of the Linear Generator - Collaborate cross-functionally with electrical engineering, manufacturing engineering, NPI, and external suppliers to deploy new designs into production, ensuring all systems meet the necessary performance and manufacturability requirements - Development of electrical hardware, including requirements development, prototyping, testing, iteration, and tooling, ensuring project milestones are met and resources are allocated effectively Qualifications: - Degree: BS or MS in Mechanical Engineering or a similar engineering field from an accredited institution. - Experience and degree will determine the level, with the following minimum requirements: - Senior: BS + 3 years or MS + 2 years - Experience designing electrical enclosure and/or cable design - Expertise in sheet metal design for medium-volume production, electrical component specification, mechanical design for electrical systems, and design-for-manufacturability challenges - A solid understanding of electrical engineering principles and thermal modeling, and the ability to integrate them effectively into larger system designs - Experience in SolidWorks and PDM (or a similar CAD version control system). - Experience with CFD, FEA, and programs like SolidWorks Flow Simulation or Ansys is a plus - Passion for creating innovative and cost-effective solutions to enable the large-scale deployment of zero-carbon energy technologies Benefits: "Along with the base salary, Mainspring offers pre-IPO stock options + benefits." Location: "This position is onsite at our Menlo Park HQ." We might also include note about salary adjustment? That's somewhat pay info but not specific; we decided not to create Pay section. Could we include a short paragraph under About the role about salary? The instruction: never create Pay/Schedule/Benefits sections unless posting actually states them. It does state that salary will be adjusted to reflect local market conditions based on employee location as well as experience. That's a statement about pay, but not a range. Should we include it? The rule says "never create Pay/Schedule/Benefits sections unless the posting actually states them." It does state something about pay (salary adjustment). So we could include a Pay section with that statement. However they also say "Prefer a few substantive sections over many thin ones." The statement is vague; maybe we can incorporate into About the role as a note. But the instruction says to use headings for those sections if we include them. If we include Pay, we need a

  Pay

  with content. The content would be: "The salary will be adjusted to reflect local market conditions based on employee location as well as the experience of the employee." That's substantive but not a range. Is that allowed? The rule says "never create Pay/Schedule/Benefits sections unless the posting actually states them." It does state that, so we could include. However they also say "never emit a heading followed by filler/placeholder text (e.g. 'commensurate with experience', 'not specified', 'N/A', 'varies', 'TBD')". The statement "adjusted to reflect local market conditions based on employee location as well as the experience of the employee" is not filler; it's a description. So we could include Pay section. Similarly Benefits we have. Schedule: they didn't state schedule (e.g., full-time, hours). So we omit Schedule. Thus sections: About the role (contains company overview + job overview + location?), Responsibilities, Qualifications, Pay, Benefits. We need to ensure we don't repeat job title as heading. We'll output HTML fragment:
