What are we building?

Unlimited is a modern engineering and construction company that builds large-scale physical infrastructure projects like factories, power plants, and industrial facilities. Most companies in this space are >100 years old. These incumbents rely on traditional methods and legacy systems, with incentives often misaligned from their customers, resulting in projects that are slow-moving, risk-averse, tech-resistant, and more expensive and complex than necessary. At the core of what we’re building is Forge - a software platform to unify all engineering and project data into one integrated system with AI as a first class citizen. This is the key to ending the current era of stagnation and reclaiming our ability to shape the physical world.

Who are we?

We are an early stage team of builders. We’ve shipped software products to millions and built infrastructure worth billions. Our current team is Alex, Jordan, Tara, James, Russ, and a couple more chemical and mechanical engineers coming soon. We’re recently raised a large Seed round from top-tier investors (will be announced in a few weeks) to build the best team in the world to tackle this ginormous $9 trillion problem. We believe this is one of the most important and largest opportunities over the next couple decades.

Your North Star

Be Unlimited Industries’ mechanical and piping engineering authority (and the basic electrical scope), delivering high quality engineering for every project and convert that know‑how into repeatable digital workflows that power our AI‑driven platform.

If you started today, what would you do?

  • End‑to‑end Mechanical & Piping Engineering for Active & Upcoming FEL 1–3 Studies
    • Prepare Mechanical design criteria, equipment lists, datasheets, specifications, weight estimates, general‑arrangement & plot‑plan layouts.
    • Define piping classes, line lists, preliminary routing, and material specifications; provide early pipe‑stress and nozzle‑load checks.
    • Compile utility balances and tie‑in data for piping & layout studies.
  • Electrical Awareness for FEL 1–2
    • Generate preliminary electrical load list, voltage levels, and power balance.
    • Draft conceptual single‑line diagram and identify major electrical equipment (transformers, MCCs, drives) for coordination with future electrical specialists.
  • Safety, Codes & Compliance
    • Lead mechanical/piping input to HAZID/HAZOP and constructability reviews.
    • Serve as Mechanical Reviewer—approve human‑ and AI‑generated calcs/drawings against ASME VIII, ASME B31.3, API 610/650, relevant Australian/US standards, etc.
  • Cross‑Discipline Coordination
    • Provide timely, accurate mechanical and piping data to process, civil/structural, electrical, and controls teams; resolve interface questions quickly.
  • Project‑Execution Support (incl. Customer Interface)
    • Populate risk registers, decision logs, and reviews for mechanical/piping items.
    • Support the Head of Projects during customer meetings: gather data, present interim results, attend site visits, and keep weekly progress touch‑points current.
    • Jump into adjacent early‑phase tasks—site feedstock analysis, procurement activities, logistics, etc.—to keep the project moving.
  • Proposal & Pre‑Sales Contribution
    • Supply mechanical equipment counts, utility summaries, layout sketches, and man‑hour estimates for new customer proposals.
  • Workflow Capture & Product Enablement
    • Document the end‑to‑end mechanical/piping FEL workflow (inputs → AI step → human QA → deliverable).
    • Package high‑repetition calc modules (e.g., pump sizing, pipe‑wall thickness, weight estimating) for software ingestion and build the initial template library.

Must Haves

  • 5+ years of experience (but more is better!) of early‑phase (FEL 1–3 / pre‑FEED) mechanical & piping engineering on process‑plant projects—has personally produced design criteria, equipment lists/datasheets, piping classes, line lists, material specs, plot plans and GA layouts.
  • Bachelor’s or higher in Mechanical Engineering
  • Expert knowledge of applicable codes: ASME VIII, ASME B31.3/B31.1, API 610/650/618, plus relevant Australian and U.S. standards; comfortable reviewing and signing off calculations and drawings as an Authorized Mechanical Reviewer.
  • Proficient with key design & analysis tools: 3‑D plant/layout software , pipe‑stress, pressure‑vessel & exchanger design, and weight / utility estimating spreadsheets; skilled at reconciling models to vendor or field data.
  • Electrical‑aware: able to generate preliminary load lists, voltage levels and single‑line diagrams sufficient for hand‑off to specialist electrical engineers.
  • Clear, concise communicator who can translate complex mechanical/piping concepts into plain language for customers, executives and non‑technical teammates.
  • First‑principles problem‑solver—breaks novel mechanical challenges down to fundamentals and captures the logic in repeatable sizing spreadsheets, scripts or templates for others to reuse.
  • Cross‑industry versatility—has applied mechanical & piping expertise in at least two sectors (e.g., oil & gas, chemicals, renewables, hydrogen, mining, food, pharma) and can carry best practices between them.
  • Bias for action and startup resilience—thrives amid shifting priorities, jumps into adjacent tasks without prodding, and maintains a high quality, high‑integrity mindset.
  • Able to work overlapping Australian & U.S. time zones and commit to ~20% travel, including short on‑site assignments.
