What is the difference between Simulation Software Engineer Internship vs Simulation Software Engineer?

AspectSimulation Software Engineer InternshipSimulation Software Engineer
Required CredentialsCurrently pursuing or recently completed a relevant degree (e.g., Computer Science, Engineering)Bachelor's or Master's degree in a related field, with some roles preferring experience or certifications
Work EnvironmentInternship programs, often in corporate R&D or product teams, with mentorshipFull-time professional role in engineering teams, often in R&D or product development
Employer & Industry UsageUsed by tech companies, automotive, aerospace, and simulation firms for training and developmentEmployed in similar industries, focusing on developing and maintaining simulation software products

The main difference is that a Simulation Software Engineer Internship is a temporary, learning-focused position for students or recent graduates, while a Simulation Software Engineer is a full-time professional role requiring more experience and responsibility in developing simulation software.

What does a simulation software engineer intern do?

A Simulation Software Engineer Intern assists in developing and testing software models that simulate real-world processes or systems. They typically work with experienced engineers to write code, debug simulations, and analyze results to ensure accuracy and efficiency. Interns may use tools such as MATLAB, Simulink, or Python, and contribute to projects in fields like automotive, aerospace, or robotics. The role helps interns gain hands-on experience in software engineering and simulation technologies, preparing them for future careers in the industry.

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

To thrive as a Simulation Software Engineer Intern, you need a strong foundation in programming languages (such as C++, Python, or MATLAB), mathematical modeling, and computer science principles, typically supported by ongoing or completed coursework in engineering or related fields. Familiarity with simulation tools (like Simulink or Modelica), version control systems (such as Git), and possibly exposure to CAD or physics engines is often required. Problem-solving abilities, attention to detail, teamwork, and effective communication are important soft skills for this role. These skills and qualities are crucial for accurately developing, testing, and refining simulation models within collaborative engineering environments.

What types of projects or tasks can I expect to work on during a simulation software engineer internship?

As a Simulation Software Engineer Intern, you will typically contribute to developing, testing, and refining simulation models used for validating real-world systems or products. Your daily tasks may include coding simulation algorithms, analyzing performance data, debugging issues, and collaborating with engineers from other disciplines such as hardware, robotics, or product design. Interns often work closely with mentors, attend team meetings, and may have opportunities to present findings or improvements. This role provides hands-on experience with industry-standard simulation tools and fosters valuable teamwork and technical skills.

Job description

PlusAI is a Physical AI company pioneering AI-based virtual driver software for factory-built autonomous trucks. Headquartered in Silicon Valley with operations in the United States and Europe, Plus was named by Fast Company as one of the World's Most Innovative Companies. Partners including TRATON GROUP's Scania, MAN, and International brands, Hyundai Motor Company, Iveco Group, Bosch, and DSV are working with Plus to accelerate the deployment of next-generation autonomous trucks. If you're ready to make a huge impact and drive the future of autonomy, Plus is looking for talented individuals to join its fast-growing teams.
We are looking for a Senior Simulation Software Engineer to build and scale the simulation infrastructure that powers our autonomous vehicle development. You will architect simulation pipelines, leverage AI agentic workflows to analyze simulation results, and drive improvements in simulation fidelity to validate autonomy systems and enable critical program milestones. This role offers the opportunity to drive immediate user value while building advanced, AI-powered frameworks for long-term safety validation.
Responsibilities
  • Design and build AI agentic workflows that automatically analyze simulation results, identify failures, and surface root causes across large-scale test runs, translating them into actionable insights for engineering teams.
  • Architect and build scalable simulation pipelines, including the metric evaluation framework, and conduct in-depth analysis of road test and simulation data to identify trends, anomalies, and key performance indicators that enhance model accuracy and validate autonomy performance.
  • Identify, quantify, and reduce sources of divergence between simulation and real-world behavior, leveraging AI and data-driven techniques to increase simulation fidelity across actor behaviors, sensor models, and system dynamics.
  • Monitor and improve the performance, scalability, testing, and reliability of the platform.
  • Collaborate with cross-disciplinary teams-including simulation, onboard, systems engineering, and data science-to reproduce and resolve issues encountered during real-world road tests.
  • Work with other engineers to design the long-term architecture of the system.
  • Ensure that technical work meets customer requirements, regulatory standards, and company quality policies, in accordance with the company's Quality Management System (QMS), and contribute to continuous improvement efforts.

Required Skills:
  • MS with 3+ years of relevant experience, or a PhD new grad, in mechanical, electrical, aerospace engineering, physics, computer science, or a related field.
  • Experience building LLM-powered or agentic workflows for data analysis, evaluation, or automation.
  • Experience quantifying or improving simulation fidelity / closing the sim-to-real gap (e.g., sensor modeling, actor behavior modeling, scenario generation).
  • Proficient in Python or C++, with experience building scalable data processing systems or evaluation frameworks.
  • Ability to solve open-ended technical challenges.
  • Excellent communication skills and the ability to collaborate effectively in a team setting.

Preferred Skills:
  • Experience with autonomous vehicle or robotics simulation and related concepts.
  • Familiarity with LLM agent frameworks (e.g., LangChain, LangGraph, or similar) and prompt/tool-orchestration patterns.
  • Experience developing metrics, user-facing APIs, or interfaces between system components.
