Houston, TX, USA
Posted on May 22, 2025
Brief Description

Amogy is an innovative cleantech startup on a mission to unlock ammonia's potential as a clean energy source. Driven by a vision of a more sustainable future, we've developed carbon-free energy solutions that leverage ammonia as an alternative fuel to decarbonize hard-to-abate sectors, including maritime shipping and stationary power generation. Join our dynamic team as we accelerate the commercialization of our technology and revolutionize the future of energy.

We’re seeking a Principal Thermal Engineer to provide technical leadership across the full product-development life-cycle for high-temperature chemical reactors and combustion-based energy systems. The role spans advanced modeling (CFD / FEA) and hands-on experimental validation, ensuring that designs meet performance, safety, and reliability targets from concept through commercialization.

What You’ll Be Doing

  • Thermal & Reaction System Design
    • Own thermal architecture for catalytic reactors, reformers, burners, and heat-exchanger networks.
    • Couple heat-/mass-transfer analyses with reaction-kinetics models to optimize efficiency, emissions, and hardware durability.
  • Computational Engineering
    • Develop and validate CFD/FEA models (e.g., ANSYS Fluent, STAR-CCM+, COMSOL) for conjugate heat transfer, multiphase flow, and reacting gases.
    • Drive mesh/solver best practices, sensitivity analyses, scale-up correlations
  • Experimental Programs
    • Design high-temperature test rigs, select reliable instrumentation, and oversee data-acquisition campaigns.
    • Translate test insights into model calibration, design updates, and specification sheets.
  • Cross-Functional Leadership
    • Partner with cross function team of mechanical, electrical, controls, and materials engineers on system integration and thermal-management strategies.
    • Provide technical mentorship; review design packages, HAZOPs, and safety cases.
  • Product & Program Support
    • Generate thermal requirements, DFMEA inputs, and validation plans.
    • Support supplier selection, factory acceptance tests, and field-commissioning troubleshooting.
Requirements

The minimum requirements we seek:

  • Education – B.S., M.S., or Ph.D. in Mechanical, Chemical, or Aerospace Engineering (or related), with focus in heat & mass transfer or combustion.
  • Experience – 10 + years in designing and analyzing high-temperature or chemically reacting systems

Technical Depth

  • Expertise in conduction, convection, radiation, phase change, diffusion, and fluid dynamics.
  • Proven track record coupling reaction kinetics with transport phenomena in catalytic or combustion devices.
  • Advanced proficiency in commercial CFD/FEA suites and scripting/post-processing.
  • Hands-on lab skills: burner or reactor setup, flow/pressure metrology, DAQ, instrumentations, & uncertainty analysis.
  • Leadership & Communication – Demonstrated ability to set technical direction, influence cross-functional teams, and present complex findings.
  • Regulatory & Safety – Working knowledge of relevant codes/standards and process safety methodologies (LOPA, HAZOP).

Preferred Experience

  • Design of reforming, hydrogen, syngas systems with combustion technologies.
  • Experience scaling prototypes to pilot- or commercial-scale manufacturing.
  • Familiarity with controls integration.

Summary

What We Offer:

  • Competitive Medical, Dental & Vision Care
  • FSA and HSA
  • 401(k) with 5% company match
  • Life insurance
  • Flexible (PTO)
  • Ancillary Benefits
  • Employee Assistance Program (EAP)
  • Open, supportive culture of drive and execution
