Job Details:

The candidate will develop run and maintain fluid and thermal models in support of launch vehicle design test and operations. This role requires strong analytical ability attention to detail and familiarity with system-level thermofluid behavior. The candidate will work with preexisting SINDA/FLUINT models port existing models to new vehicle configurations and generate engineering outputs that directly support design decisions mission timelines and subsystem sizing. A successful candidate will be comfortable working across multiple fluid subsystems and collaborating in an agile team environment.

Required Qualifications:

• Bachelors degree in mechanical engineering aerospace engineering chemical engineering or relevant field

• Experience with thermal-fluid modeling tools

• Familiarity with thermodynamics heat transfer and fluid systems

• Ability to work within a team and communicate results clearly

• Ability to obtain and maintain a security clearance

Responsibilities:

Fill and Drain

• Run SINDA/FLUINT models to support ground launch operations using established fill and drain models.

Gas Distribution

• Analyze high-to-low pressure regulation pressure-control systems and thruster supply paths using SINDA/FLUINT.

• Support valve cycle-count assessments using preexisting models.

Pneumatics System

• Run and update SINDA/FLUINT models to determine cycle counts and characterize high-to-low pressure pneumatic reduction systems.

• Update analyses to reflect evolving mission timelines.

Tank Models

• Port existing tank thermodynamics models to new vehicle geometries and mission timelines.

• Determine tank pressurization demand and bulk liquid warming during burns.

• Provide recommendations for vent and reconditioning system sizing.

Feedline Models

• Port existing feedline chilldown models to new feedline configurations.

• Determine chilldown mass requirements to meet temperature targets.

• Quantify liquid warming post-burn bleed durations orifice sizing and vehicle heat loads.

Thermal Models

• Develop detailed thermal models for fluids panels instrumentation tank penetrations and associated hardware.

• Apply boundary conditions and determine subsystem heat loads including tank boiloff.

Vent Actuator Latency Analysis

• Provide recommendations for vent-valve and actuator sizing.

• Support definition of pressure-control logic and response characteristics.

Heat Exchanger Modeling

• Develop detailed thermal models for heat exchangers and cooling subsystems.

• Generate efficiency and effectiveness values to support design and sizing.

Desired Qualifications:

• Experience with SINDA/FLUINT or similar thermal-fluid modeling tools

• Experience in aerospace fluid-systems design analysis or operations

• Experience modeling cryogenic systems feedlines pressurization networks or pneumatic systems

• Detail-oriented self-directed and motivated with strong problem-solving skills

• Ability to manage multiple tasks and deliver timely analysis in a dynamic environment
