Climate change is an existential threat, and we need as many of the world’s motivated minds as possible to help. There is no greater challenge or opportunity than fighting climate change.\n\nWe are a world-class team. We are engineers, scientists, and concerned humans from a variety of backgrounds and experiences who are pooling our knowledge and skills to collectively build a more equitable, prosperous future for all.\n\nWe remain united, resilient, and optimistic. We recognize the magnitude of the challenge ahead of us, yet believe that we can contribute to mitigating the worst effects of climate change. It won’t be easy, but we won’t quit.\n\nThe Role\nAs a Senior Mechanical Engineer within the Mechanical Department, you will own the design and execution of complex mechanical subsystems that directly influence the economics, reliability, and scalability of our core technology. This role spans early-stage R&D through NPI and site-scale deployment, requiring strong engineering fundamentals, sound judgment, and a bias toward practical, manufacturable solutions.\nYou will be expected to challenge assumptions, rigorously evaluate tradeoffs, and push the boundaries of design and manufacturing while maintaining a clear focus on cost, reliability, and long-term operability. This is a high-ownership individual contributor role with significant technical leadership and cross-functional influence.\nWhat You’ll Do\nOwn end-to-end design of complex mechanical subsystems, from requirements definition and concept architecture through validation, production ramp, and deployment\n\nDrive subsystem performance across cost, reliability, manufacturability, and serviceability, with direct impact on $/ton CO₂ economics\n\nDesign low and high-volume components using a variety of manufacturing processes, including sheet metal stamping, casting, roll forming, and extrusions\n\nLead design trade studies using first-principles analysis, data-driven methods, and sound engineering judgment\n\nDesign and develop product-level test equipment, fixtures, and validation strategies to support Design for Reliability (DfR), including accelerated life testing, stress testing, and failure-mode-driven validation to ensure robust subsystem and system performance over the intended service life\n\nPartner closely with suppliers, equipment operators, manufacturing, and supply chain teams to ensure designs are robust, scalable, and production-ready\n\nGenerate and review detailed 2D drawings with proper GD&T, aligned with production and inspection standards\n\nSupport rapid prototyping and iterative development cycles while maintaining a clear path to NPI rigor\n\nAct as a technical leader within the team by mentoring peers, driving best practices, and raising the bar for engineering quality\n\nWhat You’ll Bring\n5+ years of experience designing and delivering products through the full lifecycle, from concept to production\n\nStrong passion for product design and solving complex engineering problems with simple, robust solutions\n\nExcellent engineering fundamentals, with the ability to apply first principles, modeling, and data to real-world design decisions\n\nExperience applying Design for Reliability (DfR) principles, including failure mode identification, reliability modeling, accelerated life and stress testing, and translating test results into durable design improvements\n\nExperience with engineering analyses such as reliability modeling, tolerance analysis, FEA, fatigue analysis, and root cause analysis\n\nDemonstrated ability to lead technically complex projects or subsystems with minimal supervision\n\nProven track record of working cross-functionally to balance competing requirements and constraints\n\nExperience producing clear, accurate drawings and specifications suitable for manufacturing and inspection\n\nStrong sense of ownership, accountability, and follow-through-delivering high-quality work on schedule\n\nBonus Points\nHands-on experience designing sheet metal (stamping, press brake), weldments, and plastic parts (e.g., injection molding, thermoforming)\n\nBackground in random vibration and fatigue testing, metallurgy, material and test standards\n\nExperience managing development in a product lifecycle management system (PLM)\n\nComfort operating in both fast-paced R&D environments and the structured rigor of NPI execution\n\nExperience using NX in a production or industrial context\n\nYou don’t have to have every listed requirement and skill to be a great fit. If you are passionate about this opportunity and think you have the skills to succeed, please apply!\nOur Commitment to Diversity, Equity, and Inclusion\nWe encourage you to apply if you identify as Black, Native Hawaiian or Pacific Islander, American Indian or Alaskan Native, Hispanic or Latino, LGBTQ+ - or with any other underrepresented group - even if you don’t tick all the boxes in the description below.\nPerks and Benefits for Eligible Employees\nExcellent health, dental and vision insurance covered up to 100% by Heirloom. FSA option\n\n16 weeks paid parental leave for all Heirloom employees\n\nGenerous stock options\n\nFlexible PTO for exempt (salaried) employees & 120 hours for full time non-exempt (hourly) employees\n\n401(k)\n\nMonthly health and wellness reimbursement\n\nAnnual education and conference budget\n\nOur Principles\nRadical Honesty. We strive to foster an inclusive environment premised on transparency and respect. We push for excellence, yet always remain thoughtful when challenging each other.\n\nPersistent Optimism. We show up to work with optimism and don’t shy away from a challenge. We recognize that the ambitious nature of our mission requires hopefulness, dedication, and persistence.\n\nMaximize Learning. Compounding knowledge is our key to victory - we continuously hone our crafts, seek the fastest paths to improve, and are quick to absorb and apply new insights.","description_format":"text","description_chars":5938,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Parental leave","Stock options","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Alternative Fuels","ESG & Carbon Accounting Software"],"lifecycle":[{"event":"open","at":"2026-09-13T11:44:22Z"},{"event":"close","at":"2026-11-06T00:10:12Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 5 · green card filings: 1","filings_12m":5,"filings_prev_12m":8,"green_card_filings_12m":1,"median_offered_wage_usd":132500,"route":null,"cap_exempt":false,"checked_at":"2026-11-08T10:45:15+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":null,"pay":{"stated_usd_annual":210000,"is_top_pay":true},"html_url":"https://alion.io/job/heirloomcarbon-senior-mechanical-engineer","json_url":"https://alion.io/job/heirloomcarbon-senior-mechanical-engineer.json","meta":{"generated_at":"2026-11-09T06:50:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":3467,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":452716},"rest":"https://alion.io/mcp/rest/get_company?id=452716"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fheirloomcarbon-senior-mechanical-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fheirloomcarbon-senior-mechanical-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fheirloomcarbon-senior-mechanical-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/heirloomcarbon-senior-mechanical-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fheirloomcarbon-senior-mechanical-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":863649}},{"tool":"search_jobs","arguments":{"company":"heirloomcarbon.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":863649},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
