1D Simulation Engineer information

What is a 1D simulation engineer?

1D Simulation Engineers are professionals who use one-dimensional (1D) simulation tools to model and analyze the behavior of complex systems, such as automotive engines, hydraulic circuits, or thermal management systems. They focus on simulating the performance of these systems using mathematical models, often to predict behavior, optimize designs, or solve engineering problems before physical prototypes are built. Their work helps reduce development costs, improve efficiency, and accelerate product development cycles. 1D Simulation Engineers typically work closely with design, testing, and other engineering teams.

How does a 1D simulation engineer typically collaborate with cross-functional teams during a project?

As a 1D Simulation Engineer, you will frequently work alongside design, testing, and product development teams to ensure that simulation models align with project requirements and real-world data. Collaboration often involves sharing simulation results, validating models with physical test data, and iteratively refining system behavior based on feedback from other engineering disciplines. Effective communication and the ability to translate technical findings into actionable insights for non-simulation stakeholders are crucial for project success.

What are the key skills and qualifications needed to thrive as a 1D simulation engineer, and why are they important?

To thrive as a 1D Simulation Engineer, you need a strong background in engineering fundamentals, physics, and mathematics, typically supported by a degree in mechanical, automotive, or aerospace engineering. Proficiency with 1D simulation tools such as GT-SUITE, AMESim, or Simulink, along with experience in data analysis and modeling, is essential. Strong problem-solving abilities, attention to detail, and collaborative communication skills help distinguish top performers in this field. These skills are crucial for accurately modeling complex systems, optimizing designs, and ensuring effective teamwork in multidisciplinary engineering projects.

What is the difference between 1D Simulation Engineer vs Mechanical Design Engineer?

Aspect1D Simulation EngineerMechanical Design Engineer
Required CredentialsBachelor's or Master's in Mechanical, Aerospace, or related fields; proficiency in simulation softwareBachelor's or Master's in Mechanical Engineering; CAD and design software skills
Work EnvironmentEngineering teams, R&D labs, simulation centersDesign offices, manufacturing facilities, R&D labs
Industry UsageAutomotive, aerospace, energy sectors focusing on system-level simulationsProduct development, machinery, consumer electronics

The main difference is that a 1D Simulation Engineer specializes in creating and analyzing system-level simulations using specialized software, focusing on fluid dynamics, thermodynamics, and system behavior. In contrast, a Mechanical Design Engineer primarily focuses on designing physical components and assemblies. Both roles require engineering credentials, but their daily tasks and tools differ significantly.

Job description

Role Overview

We're looking for a Thermodynamics Performance Engineer to own the dynamic and steady-state thermodynamic models of our direct-fired supercritical CO Brayton cycle. You'll be the person who turns integrated system behavior into clear, actionable insight - running performance studies ahead of test campaigns, reconciling predictions against test data, and growing our modeling capability into a digital-twin-quality simulation platform that supports controls development, trip response, and eventual hardware-in-the-loop testing. You'll work closely with our test, combustion, turbomachinery, recuperator, fluid systems, and controls engineers. This is the simulation backbone for a first-of-a-kind power system, and the work is foundational to how we operate, validate, and scale the technology.

This is an onsite opportunity in our El Segundo, CA office. 

Responsibilities
  • Own the integrated cycle performance model - steady-state and dynamic - for our direct-fired sCO Brayton power loop, maintaining and advancing it through the hardware lifecycle
  • Run performance prediction and sensitivity studies ahead of test campaigns; reconcile model output against test data to drive model refinement and surface component-level insights
  • Own the architecture call on how our dynamic modeling stack should evolve over time - what platform, what fidelity, on what evidence
  • Build property tables, turbomachinery map handling, heat exchanger transient models, and combustor representations appropriate to the cycle and fidelity required
  • Collaborate with combustion, turbomachinery, and heat exchanger engineers to integrate component data into system-level models; collaborate with controls and software teams on closed-loop simulation and HIL planning
  • Develop simulation infrastructure - scripted scenario runs, parameter sweeps, validation cases - that makes the model usable by engineers beyond yourself
Requirements
  • Bachelor's degree in Chemical, Mechanical, Aerospace, Nuclear, or related Engineering field
  • 4+ years of experience in cycle performance analysis, thermodynamic systems modeling, or dynamic process simulation
  • Strong fundamentals in thermodynamics, fluid mechanics, and heat transfer, applied to integrated multi-component systems
  • Demonstrated experience building dynamic simulation models of fluid/thermal systems in an industry-grade 1D system simulation platform - and a clear point of view on tool tradeoffs for closed-loop power cycle applications
  • Working knowledge of integrated power loop equipment - heat exchanger sizing, compressor/pump curves, valve Cv, piping hydraulics - and how each shows up in dynamic response
  • Programming proficiency: Python for data reduction and automation; one of MATLAB/Simulink, Modelica, or equivalent for modeling
  • Strong ownership mentality and comfort driving rigorous analysis in a fast-paced startup environment
Preferred Qualifications
  • Deep experience with industry dynamic simulation platforms (such as GT-SUITE, Modelica/Dymola, NPSS, Flownex, Simcenter Amesim, or equivalent) applied to turbomachinery, power cycles, or closed-loop thermal-fluid systems
  • Background in nuclear thermal-hydraulics with fast-dynamic single-phase modeling experience (RELAP, TRACE, MARS, ATHLET, GAMMA, or equivalent), particularly applied to gas-cooled or sCO reactor concepts
  • Working knowledge of real-fluid EOS handling (REFPROP, CoolProp, Span-Wagner) and turbomachinery map interpolation near critical conditions
  • History of making and defending tool/methodology decisions in a constrained engineering environment
  • Experience with supercritical CO, closed Brayton cycles, high-pressure systems (100+ bar), or other high-density working fluids
  • Experience coupling plant models to control systems for HIL testing, controller validation, FMU export, or operator training simulators
  • Hands-on plant startup, commissioning, or field troubleshooting on first-of-a-kind or developmental systems
  • Background in rocketry, gas turbine, advanced reactors, or high-performance turbomachinery environments
Compensation & Benefits
  • Pre-IPO stock options
  • Medical, dental, and vision insurance (Arbor covers 90% for employees)
  • Basic life insurance fully covered
  • Health savings account (HSA) with matching
  • Flexible savings account (FSA)
  • Unlimited PTO 
  • 12+ company holidays, including Earth Day! 
  • 401(k)
  • Commuter benefits
  • Annual learning and development stipend
  • And more!

Base Pay: $140,000 - $155,000 USD/year. The salary is subject to the applicant's skills, qualifications, experience, and geographic location.
