About Ammobia

Ammobia is on a mission to revolutionize the ammonia industry. We are a seed-stage startup developing Haber Bosch 2.0 – a next-generation ammonia synthesis process enabling cost-effective, clean ammonia production. Until now, ammonia production has been a highly polluting, steady-state, high inertia process. We are developing new regimes of physics and plant design that require dynamic processes, especially for ammonia production from intermittent renewable energy sources. Clean ammonia will support ammonia’s growing role in our decarbonized world, tackling some of the most difficult to abate sectors including chemicals, fertilizers, and heavy-duty transportation. We are supported by leading climate tech organizations including Starlight Ventures, Collaborative Fund, Third Derivative, Forbes 30u30, and more.

Job Description

    Ammobia is seeking a do-it-all engineering technician with a bias towards action and
    rapid design cycles. You have industrial experience in chemicals, energy systems,
    aerospace, or other dynamic fluid systems. You will build, wire, assemble, maintain,
    and operate a pilot-scale reactor system. You are comfortable getting your hands dirty,
    building from scratch, and identifying where to bring in outside vendors/engineers.
    You are comfortable working on pilot-scale machinery with little supervision.
    There will be significant opportunity to grow your role with the company.
    Responsibilities may include:
    • Assembly, disassembly, upkeep and maintenance of Ammobia’s pilot plant.
    • Install power and signal wiring within control panels and between control panels
    and field instrumentation, and for other controls and electrical subsystems as
    needed.
    • Assemble, leak check, disassemble Swagelok tube fittings, NPT threaded
    fittings, Grayloc clamp fittings, and other process connections as needed.
    • Commission pilot plant equipment alongside engineers, including electrical and
    controls tasks such as loop checking, instrument calibrations, and equipment
    function checks.
    • Operate the pilot plant on shift teams with an Ammobia engineer on 8- or 12-
    hour shifts as needed, adhering to safety protocols and executing experimental
    campaigns on individual- and multi-module modes of operation.• Implement changes and improvements to the pilot plant to achieve target
    performance metrics.
    • Create, install, and troubleshoot mechanical, electrical, and controls subsystems.
    • Troubleshoot electrical and mechanical equipment, sensors, and mechanical
    parts as needed to restore pilot machines.
    • Work hands-on building systems, as well as supervise and mentor junior
    technicians and interns.
    • Maintain a robust document management system for pilot equipment that
    includes revision control (P&ID, SOP’s, electrical diagrams).
    • Maintain the workspace and ensure tools and spare parts are well stocked.

Who You Are

    • 4+ years hands-on experience in relevant industrial setting.
    • Demonstrated capability to work safely at the lab-, pilot-, or industrial-scale.
    • Practical experience reading and understanding process and instrumentation
    diagrams (P&IDs).
    • Deep experience working with high pressure fluid lines: Swagelok-style gas
    delivery systems, gas cylinders, manifolds, pressure vessels, heaters, and similar.
    • Practical experience installing, wiring power and signal for, and maintaining
    hardware such as compressors, pumps, heaters, and instrumentation such as
    pressure transducers, thermocouples, mass flow controllers, valves, filters, and
    pressure regulators.
    • Practical experience assembling/disassembling custom mechanical and electrical
    systems, including building modular frames from 80/20 T-slot aluminum framing.
    • Experience working with industrial instrumentation and control systems (e.g.
    PLC, LabVIEW, or similar).
    • Experience working with power tools, basic fabrication, and electrical control
    panels.
    • Self-motivated, hands-on attitude, with a willingness to contribute at all levels.
    • Prior experience working with industrial and electrical design practices, codes,
    and standards for working with high pressure systems.

Nice to Haves

  • Experience with hydrogen, ammonia, other flammables/corrosives, and compressed gases.

  • Proficiency in electrical and controls design

  • Experience operating pilot plants, production lines, or large laboratory systems on a shifted schedule

  • Experience in start-up environments

  • Experience overseeing and maintaining lab space/ machine shop space/ factory

  • Familiarity with chemical processing systems
