Job summary

RTX is seeking an Affordability Engineer II for an onsite role in Tucson, AZ. You will develop discrete event simulation models to identify throughput bottlenecks and resource constraints, using data from engineering, operations, and supply chains.

Responsibilities include multi-scenario analyses, documenting assumptions, and supporting lifecycle cost and readiness studies while collaborating with cross-functional teams to align outputs with program requirements.

Qualifications

• Degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 2 years of experience.
• Experience in systems engineering, operations research, industrial engineering or related analytical disciplines.
• Experience working with structured datasets (Excel, CSV, databases) for data analysis and model input preparation.

Responsibilities

• Develop, execute, and maintain discrete event simulation models to analyze throughput, queueing behavior, cycle time, resource constraints, and system bottlenecks.
• Prepare model input datasets using validated engineering, operations, supplier, and sustainment data.
• Identify and characterize constraints across production lines, supply chain flows, and sustainment/repair loops.
• Analyze the impact of design decisions, yield variations, staffing assumptions, or supplier performance on system throughput and affordability.
• Conduct multi-scenario studies, sensitivity analyses, and parameter sweeps.
• Document model assumptions, boundaries, and data traceability to ensure credibility and repeatability.
• Support affordability assessments, including lifecycle cost modeling, business case analyses, and readiness/availability studies.
• Collaborate with Affordability Leads and cross-functional teams to align model outputs with program requirements.
• Update model inputs as new data becomes available to ensure accurate reflection of system behavior.
