We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.\nRole Overview\nWe are hiring a Manager, Piping Design & Engineering to build and lead the piping discipline behind our refining and minerals processing facilities. The team, the 3D model, the design workflows, and the standards every piping deliverable comes out of.\nYou will own Mariana's piping design group: the designers who build the model, the stress engineers who validate it, and the staff-aug, high-value engineering center, and EPC piping teams that extend it. You own the 3D model as the source of truth, including the metadata behind it, and you develop the workflow that carries a line from P&ID to routed model to stress-checked to supported to issued for construction. You'll also set the stress criteria, own the piping material, valve, and support specifications, and pick up Caesar II or the model yourself when the work calls for it.\nWhat You’ll Do\nLead the piping design team\nBuild and lead Mariana's piping design group. Hire, develop, and directly manage piping designers and stress engineers\n\nManage the blended delivery team. In-house, staff-augs, high-value engineering centers, and third-party engineering firm piping groups\n\nLoad-balance work across concurrent projects, hold the schedule for piping deliverables, and coach designers through the work\n\nAttract non-conventional engineering talent to piping design and engineering positions to develop advanced automation solutions\n\nOwn the 3D model\nOwn 3D model development end to end in Plant 3D and Revit. Plot plan and equipment layout through routing, supports, and IFC isometrics\n\nOwn how the model is built: structure and breakdown, project setup, naming conventions, revision control, and change rights\n\nOwn the spec catalogs and component libraries inside the model, so piping specs are enforced by the model rather than caught in review\n\nRun 30 / 60 / 90% model reviews and Navisworks clash detection across disciplines, and drive resolution to closure\n\nDefine the model, drawing, and file format requirements EPCs and vendors deliver against, and integrate their content into Mariana's environment\n\nKeep the model the single source of truth for quantities. Isometrics, BOMs, and take-offs generated from the model, not maintained beside it\n\nEvaluate and implement state of the art agentic engineering and automation softwares\n\nDevelop the design workflows and standards\nDevelop and implement the piping design workflow itself. The path from P&ID to IFC, what gets checked at each gate, and who signs it\n\nBuild the standards behind it: piping design criteria, layout and access standards, drafting standards, iso and drawing templates, and support detail libraries\n\nEstablish squad check and design checking practice, with disciplined comment resolution, revision control, and IFR / IFA / IFC issue\n\nAutomate the repetitive work with our software team. Model-to-stress data exchange, spec-driven checks, quantity reporting, and QC scripting\n\nOwn the engineering and stress scope\nOwn the pipe stress program. Set the criteria, decide which lines are critical, and approve every package before it drives a support or a nozzle\n\nDirect dynamic analyses. Slug flow, water hammer, relief valve transients, and vibration\n\nOwn piping material specifications, valve specs, and engineering standards, including material selection for hydromet, pyromet, and reagent services\n\nDesign and specify pipe supports, guides, anchors, expansion joints, and specialty components, and own the support detail standards\n\nEnsure all piping systems comply with ASME B31.3, and B31.1 where applicable\n\nDrive piping procurement and support construction and commissioning. Bulk material strategy, long-lead valves and specialty items, field RFIs, redlines, and as-built model closeout\n\nWhat You’ll Bring\n10+ years in piping design and engineering, delivered in an EPC, EPCM, or owner capital projects environment\n\nDirect experience managing a piping design department or group\n\nDemonstrated ownership of 3D model development on a capital project, concept through IFC, including multidiscipline reviews and Navisworks clash detection\n\nTrack record building piping design workflows and standards\n\nStrong pipe stress background in Caesar II\n\nDepth in ASME B31.3, including allowable load definition and nozzle load evaluation\n\nExperience developing piping material and valve specifications and pipe support design criteria\n\nBachelor's degree in Mechanical Engineering or a related field\n\nPreferred, but not required\nProfessional Engineer (PE) license, or the ability to obtain one\n\nMining, mineral processing, metallurgical, chemical, or heavy industrial facility experience\n\nSlurry, reagent, and high-temperature or refractory-lined piping, including lined and non-metallic materials\n\nScripting or model-based automation\n\nOur culture is built on four principles:\nEveryone Gets Home Safe. We never put speed or cost ahead of people.\nExtreme Ownership. We take full responsibility for outcomes, relentlessly driving toward solutions.\nEngineer Out Requirements, then Automate. We simplify, optimize, and then automate for scale.\nShare Your Legos. We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.\nJoin us as we build the future of responsible mineral sourcing and supply!","description_format":"text","description_chars":5619,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Mining","Mining Tech","Non-ferrous Metals"],"lifecycle":[{"event":"open","at":"2026-04-17T18:13:40Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 15","filings_12m":15,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":152500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.384,"p_room":0.28,"age_days":193,"expected_fill_days":40,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-28T05:59:10Z"},"pay":{"stated_usd_annual":210000,"is_top_pay":true},"html_url":"https://alion.io/job/mariana-minerals-manager-piping-design-engineering","json_url":"https://alion.io/job/mariana-minerals-manager-piping-design-engineering.json","meta":{"generated_at":"2026-10-28T23:48:07Z","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":32678,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"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":8004},"rest":"https://alion.io/mcp/rest/get_company?id=8004"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmariana-minerals-manager-piping-design-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"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%2Fmariana-minerals-manager-piping-design-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"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%2Fmariana-minerals-manager-piping-design-engineering"},{"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/mariana-minerals-manager-piping-design-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmariana-minerals-manager-piping-design-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":128871}},{"tool":"search_jobs","arguments":{"company":"marianaminerals.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":128871},"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.
