What you will do

• Architect and own high-fidelity simulators for large, distributed systems with complex interactions, feedback loops, and failure modes.
• Model system dynamics and control behavior across nominal and off-nominal operating conditions.
• Build scalable infrastructure for high-volume simulation, scenario generation, and automated validation.
• Define correctness criteria and validate simulation outputs against test and real-world data.
• Collaborate with hardware, chemical, electrical, systems, and engineering teams to improve testing and simulation capabilities.
• Define architecture, implementation standards, and operational reliability practices for mission-critical simulation systems.

Requirements

• Bachelor’s degree in Computer Science, Electrical Engineering, Mechanical Engineering, Physics, or a related field; an advanced degree is preferred.
• 7+ years of experience building simulators for complex, real-world systems.
• Strong programming skills in C++ and/or Python, including experience handling large data flows.
• Deep understanding of distributed systems, control systems, or physical-process modeling.
• Experience validating simulations against empirical data or hardware-in-the-loop setups.
• Ability to work extended hours and weekends when necessary.

Nice to have

• Experience simulating industrial, aerospace, energy, chemical plant, rocket, or power-grid systems.
• Background in control theory, numerical methods, or systems modeling.
• Experience with large-scale simulations for design validation or fault analysis.
• Familiarity with performance optimization and parallel or distributed simulation.
• Experience in high-stakes engineering environments where correctness is critical.
