ETCH, INC

Thermal Mechanical Engineer – Job Description

Baltimore, MD Full-time

ETCH is a startup commercializing a radically new and efficient decarbonization technology for the simultaneous greenhouse gas-free production of hydrogen and solid carbon from natural gas.

Primary duties include leading the design and development of advanced reactor systems and supporting infrastructure. This role will be central to scaling from pilot to commercial systems, with a strong emphasis on reactor bundles, high-temperature design, and balance-of-plant (BOP) integration. Focus will be on design, improving performance and efficiency, and safety of the processes all while driving continuous improvements and innovations.

Other duties include:

Reactor & Core System Design

Design and optimize annulus reactor bundles, including thermal uniformity, flow distribution, and mechanical integrity
Develop detailed mechanical designs for pilot reactor modifications and scale-up to 5 MTPD (metric tons per day) reactor systems
Perform thermal and structural calculations for high-temperature operation (≥1000°C environments)
Evaluate materials of construction considering creep, thermal expansion, and chemical compatibility

Structural & Mechanical Systems

Design structural supports for reactor systems, accounting for thermal expansion, vibration, and load conditions
Ensure mechanical robustness and maintainability of reactor assemblies
Develop expansion joints, supports, and interfaces between hot and cold sections

Balance of Plant (BOP) & Layout

Lead mechanical design and layout for balance-of-plant systems, including:
Heat exchangers
Piping systems
Valves and flow control
Gas handling systems
Develop plant layout and equipment arrangement for pilot and commercial facilities
Ensure proper integration between reactor core and BOP systems

Engineering Analysis & Optimization

Conduct thermal modeling (CFD/FEA preferred) and heat transfer analysis
Perform stress analysis and lifecycle evaluation of critical components
Support optimization of system efficiency, uptime, and reliability

Execution & Scale-Up

Support transition from pilot to commercial-scale systems
Work closely with fabrication teams, vendors, and operations
Participate in installation, commissioning, and troubleshooting

Qualifications:

Education: Bachelor’s or Master’s degree in Mechanical Engineering or related field
5+ years of experience in: High-temperature systems, Reactor design / process equipment, Thermal systems engineering
Experience with chemical plants, hydrogen systems, pyrolysis, or similar is highly preferred
Strong fundamentals in: Heat transfer, Fluid mechanics, Structural mechanics
Experience with:
CAD tools (SolidWorks, Inventor, or similar)
FEA/CFD tools (ANSYS, COMSOL, etc.)
High-temperature alloys, ceramics, and refractory materials
Pressure systems and piping design codes (ASME preferred)

Preferred Attributes

Experience designing modular or bundled reactor systems
Familiarity with scale-up challenges (pilot → commercial)
Hands-on mindset with ability to work in fast-paced startup environments
Strong problem-solving and ownership attitude

An ability to work independently as well as in a team environment toward timely execution of goals is required.
